capped in area so designated as 'historic'. Critics of historic districts argue that while these districts may offer an aesthetic or visually pleasing benefit, they increase inequality by restricting access to new and affordable housing for lower and middle class tenants and potential home owners. Canada In Canada, such districts are called "heritage conservation districts" or "heritage conservation areas" (known as "arrondissements historiques", "secteurs de conservation du patrimoine" or "districts de conservation du patrimoine" in French) and are governed by provincial legislation.

A historic district or heritage district is a section of a city which contains older buildings considered valuable for historical or architectural reasons. In some countries or jurisdictions, historic districts receive legal protection from certain types of development. Historic districts may or may not also be the center of the city. They may be coterminous with the commercial district, administrative district, or arts district, or separate from all of these. Historical districts are often parts of a larger urban setting, but they can also be parts or all of small towns, or a rural areas with historic agriculture-related properties, or even a physically disconnected series of related structures throughout the region. Much criticism has arisen of historic districts and the effect protective zoning and historic designation status laws have on the housing supply. When an area of a city is designated as part of a 'historic district', new housing development is artificially restricted and the supply of new housing permanently capped in area so designated as 'historic'.

Canada In Canada, such districts are called "heritage conservation districts" or "heritage conservation areas" (known as "arrondissements historiques", "secteurs de conservation du patrimoine" or "districts de conservation du patrimoine" in French) and are governed by provincial legislation. Taiwan In Taiwan, the Cultural Heritage Preservation Act  protects certain historic districts under the "groups of buildings" category. Districts are overseen by their respective municipality, city, or county governments, but can also be promoted to a "significant" status and overseen by the Ministry of Culture directly.

ited States, a contractor may be a sole proprietor managing a project and performing labor or carpentry work, have a small staff, or may be a very large company managing billion dollar projects. Some builders build new homes, some are remodelers, some are developers. Licensing requirements to work legally on construction projects vary from locale to locale. Description A general contractor is a construction manager employed by a client, usually upon the advice of the project's architect or engineer. General contractors are mainly responsible for the overall coordination of a project and may also act as building designer and construction foreman (a tradesman in charge of a crew). A general contractor must first assess the project-specific documents (referred to as a bid, proposal, or tender documents). In the case of renovations, a site visit is required to get a better understanding of the project. Depending on the project delivery method, the general contractor will submit a fixed price proposal or bid, cost-plus price or an estimate. The general contractor considers the cost of home office overhead, general conditions, materials, and equipment, as well as the cost of labor, to provide the owner with a price for the project. Contract documents may include drawings, project manuals (including general, supplementary, or special conditions and specifications), and addendum or modifications issued prior to proposal/bidding and prepared by a design professional, such as an architect.The general contractor may also assume the role of construction manager, responsible for overseeing the project while assuming financial and legal risks.

Responsibilities General contractors are responsible for the day-to-day oversight of a construction site, management of vendors and trades, and the communication of information to all involved parties throughout the course of a building project. A general contractor is responsible for providing all of the material, labor, equipment (such as heavy equipment and tools) and services necessary for the construction of the project. A general contractor often hires specialized subcontractors to perform all or portions of the construction work. When using subcontractors, the general contractor is responsible for overseeing the quality of all work performed by any and all of the workers and subcontractors. It is a best practice for general contractors to prioritize safety on the job site, and they are generally responsible for ensuring that work takes place following safe practices. A general contractor's responsibilities may include applying for building permits, advising the person they are hired by, securing the property, providing temporary utilities on site, managing personnel on site, providing site surveying and engineering, disposing or recycling of construction waste, monitoring schedules and cash flows, and maintaining accurate records. The general contractor may be responsible for some part of the design, referred to as the "contractor's design portion" (JCT terminology). Terminology United Kingdom, Commonwealth and Australia usage In the United Kingdom, Australia and some British Commonwealth countries, the term general contractor was gradually superseded by builders during the early twentieth century. This was the term used by major professional, trade, and consumer organizations when issuing contracts for construction work, and thus the term general contractor fell out of use except in large organizations where the main contractor is the top manager and a general contractor shares responsibilities with professional contractors. General contractors who conduct work for government agencies are often referred to as builders. This term is also used in contexts where the customer's immediate general contractor is permitted to sub-contract or circumstances are likely to involve sub-contracting to specialist operators, e.g.

Desk" of 1915. Its flat top, with drawers below, was designed to allow managers an easy view of their workers. By the middle of the 20th century, it became apparent that an efficient office required additional control over privacy, and gradually the cubicle system evolved. History The word "office" stems from the Latin "officium" and its equivalents in various Romance languages. An officium was not necessarily a place, but often referred instead to human staff members of an organization, or even the abstract notion of a formal position like a magistrate. The elaborate Roman bureaucracy would not be equaled for centuries in the West after the fall of Rome, with areas partially reverting to illiteracy. Further east, the Byzantine Empire and varying Islamic caliphates preserved a more sophisticated administrative culture. Offices in classical antiquity were often part of a palace complex or a large temple. There was often a room where scrolls were kept and scribes did their work. Ancient texts mentioning the work of scribes allude to the existence of such "offices". These rooms are sometimes called "libraries" by some archaeologists because of scrolls' association with literature.

th a desk and chair, an office is also an architectural and design phenomenon, including small offices, such as a bench in the corner of a small business or a room in someone's home, entire floors of buildings, and massive buildings dedicated entirely to one company. In modern terms, an office is usually the location where white-collar workers carry out their functions. In classical antiquity, offices were often part of a palace complex or a large temple. In the High Middle Ages (1000–1300), the medieval chancery acted as a sort of office, serving as the space where records and laws were stored and copied. With the growth of large, complex organizations in the 18th century, the first purpose-built office spaces were constructed. As the Industrial Revolution intensified in the 18th and 19th centuries, the industries of banking, rail, insurance, retail, petroleum, and telegraphy grew dramatically, requiring many clerks. As a result, more office space was assigned to house their activities. The time-and-motion study, pioneered in manufacturing by F. W. Taylor (1856–1915), led to the "Modern Efficiency Desk" of 1915. Its flat top, with drawers below, was designed to allow managers an easy view of their workers.

The High Middle Ages (1000–1300) saw the rise of the medieval chancery, which was the place where most government letters were written and laws were copied within a kingdom. The rooms of the chancery often had walls full of pigeonholes, constructed to hold rolled-up pieces of parchment for safekeeping or ready reference. This kind of structure was a precursor to the modern bookshelf. The introduction of the printing press during the Renaissance did not impact the setup and function of these government offices significantly. Medieval paintings and tapestries often show people in their private offices handling record-keeping books or writing on scrolls of parchment. Before the invention of the printing press and its wider distribution, there was often no clear cultural distinction between a private office and a private library; books were both read and written at the same desk or table, as were personal and professional accounts and letters. During the 13th century, the English word "office" first began to appear when referring to a position involving specific professional duties (for example, "the office of the....") Geoffrey Chaucer appears to have first used the word in 1395 to mean a place where business is transacted in The Canterbury Tales. As mercantilism became the dominant economic theory of the Renaissance, merchants tended to conduct their business in buildings that also sometimes housed people doing retail sales, warehousing, and clerical work. During the 15th century, the population density in many cities reached a point where merchants began to use stand-alone buildings to conduct their businesses.

ited States federal government's official list of sites, buildings, structures, districts, and objects deemed worthy of preservation for their historical significance or "great artistic value". The enactment of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 100,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the United States Department of the Interior. Its goals are to help property owners and interest groups, such as the National Trust for Historic Preservation, and coordinate, identify and protect historic sites in the United States. While National Register listings are mostly symbolic, their recognition of significance provides some financial incentive to owners of listed properties. Protection of the property is not guaranteed. During the nomination process, the property is evaluated in terms of the four criteria for inclusion on the National Register of Historic Places. The application of those criteria has been the subject of criticism by academics of history and preservation, as well as the public and politicians. A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. Properties can be nominated in various forms, including individual properties, historic districts and multiple property submissions (MPS). The Register categorizes general listings into one of five types of properties: district, site, structure, building or object. National Register Historic Districts are defined geographical areas consisting of contributing and non-contributing properties. Some properties are added automatically to the National Register when they become administered by the National Park Service.

s (NHLD), National Historic Sites (NHS), National Historical Parks, National Military Parks, national memorials, and some national monuments. History On October 15, 1966, the Historic Preservation Act created the National Register of Historic Places and the corresponding State Historic Preservation Offices (SHPO). The National Register initially consisted of the National Historic Landmarks designated before the Register's creation, as well as any other historic sites in the National Park System. Approval of the act, which was amended in 1980 and 1992, represented the first time the United States had a broad-based historic preservation policy. The 1966 act required those agencies to work in conjunction with the SHPO and an independent federal agency, the Advisory Council on Historic Preservation (ACHP), to confront adverse effects of federal activities on historic preservation. To administer the newly created National Register of Historic Places, the National Park Service of the U.S. Department of the Interior, with director George B. Hartzog Jr., established an administrative division named the Federal Office of Archaeology and Historic Preservation (OAHP). Hartzog charged OAHP with creating the National Register program mandated by the 1966 law. Ernest Connally was the Office's first director. Within OAHP new divisions were created to deal with the National Register. The division administered several existing programs, including the Historic Sites Survey and the Historic American Buildings Survey, as well as the new National Register and Historic Preservation Fund. The first official Keeper of the Register was William J. Murtagh, an architectural historian. During the Register's earliest years in the late 1960s and early 1970s, organization was lax and SHPOs were small, understaffed and underfunded. However, funds were still being supplied for the Historic Preservation Fund to provide matching grants-in-aid to listed property owners, first for house museums and institutional buildings, but later for commercial structures as well. In 1979, the NPS history programs affiliated with both the U.S. National Park system and the National Register were categorized formally into two "Assistant Directorates". Established were the Assistant Directorate for Archeology and Historic Preservation and the Assistant Directorate for Park Historic Preservation. From 1978 until 1981, the main agency for the National Register was the Heritage Conservation and Recreation Service (HCRS) of the United States Department of the Interior. In February 1983, the two assistant directorates were merged to promote efficiency and recognize the interdependency of their programs. Jerry L. Rogers was selected to direct this newly merged associate directorate. He was described as a skilled administrator, who was sensitive to the need for the NPS to work with SHPOs, academia and local governments. Although not described in detail in the 1966 act, SHPOs eventually became integral to the process of listing properties on the National Register. The 1980 amendments of the 1966 law further defined the responsibilities of SHPOs concerning the National Register. Several 1992 amendments of the NHPA added a category to the National Register, known as Traditional Cultural Properties: those properties associated with Native American or Hawaiian groups. The National Register of Historic Places has grown considerably from its legislative origins in 1966. In 1986, citizens and groups nominated 3,623 separate properties, sites and districts for inclusion on the National Register, a total of 75,000 separate properties. Of the more than one and a half million properties on the National Register, 100,000 are listed individually.

Criterion A, "Event", the property must make a contribution to the major pattern of American history. Criterion B, "Person", is associated with significant people of the American past. Criterion C, "Design/Construction", concerns the distinctive characteristics of the building by its architecture and construction, including having great artistic value or being the work of a master. Criterion D, "Information potential", is satisfied if the property has yielded or may be likely to yield information important to prehistory or history. The criteria are applied differently for different types of properties; for instance, maritime properties have application guidelines different from those of buildings.

In urban planning, zoning is a method in which a municipality or other tier of government divides land into land-use and building "zones", each of which has a set of regulations for new development that differs from other zones. Zones may be defined for a single use (e.g. residential, industrial), they may combine several compatible activities by use, or in the case of form-based zoning, the differing regulations may govern the density, size and shape of allowed buildings whatever their use. The planning rules for each zone determine whether planning permission for a given development may be granted. Zoning may specify a variety of outright and conditional uses of land. It may indicate the size and dimensions of lots that land may be subdivided into, or the form and scale of buildings. These guidelines are set in order to guide urban growth and development. Zoning is the most common regulatory urban planning method used by local governments in developed countries. Exceptions include the United Kingdom and the city of Houston, Texas.

FIDIC's PSM The International Federation of Consulting Engineers (FIDIC) Project Sustainability Management Guidelines were created to assist project engineers and other stakeholders in setting sustainable development goals for their projects that are recognized and accepted as being in the interests of society. The process is also intended to align project goals with local conditions and priorities and assist those involved in managing projects to measure and verify their progress. The Project Sustainability Management Guidelines are structured with Themes and Sub-Themes under the three main sustainability headings of Social, Environmental and Economic. For each individual Sub-Theme a core project indicator is defined along with guidance as to the relevance of that issue in the context of an individual project. The Sustainability Reporting Framework provides guidance for organizations to use as the basis for disclosure about their sustainability performance, and also provides stakeholders a universally applicable, comparable framework in which to understand disclosed information. The Reporting Framework contains the core product of the Sustainability Reporting Guidelines, as well as Protocols and Sector Supplements. The Guidelines are used as the basis for all reporting. They are the foundation upon which all other reporting guidance is based, and outline core content for reporting that is broadly relevant to all organizations regardless of size, sector, or location. The Guidelines contain principles and guidance as well as standard disclosures – including indicators – to outline a disclosure framework that organizations can voluntarily, flexibly, and incrementally adopt. Protocols underpin each indicator in the Guidelines and include definitions for key terms in the indicator, compilation methodologies, intended scope of the indicator, and other technical references. Sector Supplements respond to the limits of a one-size-fits-all approach. Sector Supplements complement the use of the core Guidelines by capturing the unique set of sustainability issues faced by different sectors such as mining, automotive, banking, public agencies and others. IPD Environment Code The IPD Environment Code was launched in February 2008. The Code is intended as a good practice global standard for measuring the environmental performance of corporate buildings. It aims to accurately measure and manage the environmental impacts of corporate buildings and enable property executives to generate high-quality, comparable performance information about their buildings anywhere in the world.

Green building (also known as green construction, sustainable building, or eco-friendly building) refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throughout a building's life cycle: from planning to design, construction, operation, maintenance, renovation, and demolition. This requires close cooperation between the contractor, the architects, the engineers, and the client at all project stages. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green building also refers to saving resources to the maximum extent, including energy saving, land saving, water saving, material saving, etc., during the whole life cycle of the building, protecting the environment and reducing pollution, providing people with healthy, comfortable and efficient use of space, and being in harmony with nature. Buildings that live in harmony; green building technology focuses on low consumption, high efficiency, economy, environmental protection, integration and optimization. Leadership in Energy and Environmental Design (LEED) is a set of rating systems for the design, construction, operation, and maintenance of green buildings, developed by the U.S. Green Building Council. The Green Building Initiative (GBI) is an American National Standards Institute (ANSI) accredited standards developer and the provider of numerous green building assessments and certifications, including Green Globes. Other certification systems that confirm the sustainability of buildings are the British BREEAM (Building Research Establishment Environmental Assessment Method) for buildings and large-scale developments or the DGNB System (Deutsche Gesellschaft für Nachhaltiges Bauen e.V.) which benchmarks the sustainability performance of buildings, indoor environments, and districts. Currently, the World Green Building Council is researching the effects of green buildings on the health and productivity of their users and is working with the World Bank to promote green buildings in Emerging Markets through EDGE (Excellence in Design for Greater Efficiencies) Market Transformation Program and certification. There are also other tools such as NABERS or Green Star in Australia, Global Sustainability Assessment System (GSAS) used in the Middle East and the Green Building Index (GBI) predominantly used in Malaysia. Building information modeling (BIM) is a process involving the generation and management of digital representations of the physical and functional characteristics of places. Building information models (BIMs) are files (often, but not always in proprietary formats and containing proprietary data) which can be extracted, exchanged, or networked to support decision-making regarding a building or other built asset.

rpenters normally framed post-and-beam buildings until the end of the 19th century; now this old-fashioned carpentry is called timber framing. Carpenters learn this trade by being employed through an apprenticeship training—normally four years—and qualify by successfully completing that country's competence test in places such as the United Kingdom, the United States, Canada, Switzerland, Australia and South Africa.

Training Carpentry requires training which involves both acquiring knowledge and physical practice. In formal training a carpenter begins as an apprentice, then becomes a journeyman, and with enough experience and competency can eventually attain the status of a master carpenter. Today pre-apprenticeship training may be gained through non-union vocational programs such as high school shop classes and community colleges. Informally a laborer may simply work alongside carpenters for years learning skills by observation and peripheral assistance. While such an individual may obtain journeyperson status by paying the union entry fee and obtaining a journeyperson's card (which provides the right to work on a union carpentry crew) the carpenter foreperson will, by necessity, dismiss any worker who presents the card but does not demonstrate the expected skill level. Carpenters may work for an employer or be self-employed. No matter what kind of training a carpenter has had, some U.S.

Formal training in the carpentry trade is available in seminars, certificate programs, high-school programs, online classes, in the new construction, restoration, and preservation carpentry fields. Sometimes these programs are called pre-apprenticeship training. In the modern British construction industry, carpenters are trained through apprenticeship schemes where general certificates of secondary education (GCSE) in Mathematics, English, and Technology help but are not essential. However, this is deemed the preferred route, as young people can earn and gain field experience whilst training towards a nationally recognized qualification. There are two main divisions of training: construction-carpentry and cabinetmaking. During pre-apprenticeship, trainees in each of these divisions spend 30 hours a week for 12 weeks in classrooms and indoor workshops learning mathematics, trade terminology, and skill in the use of hand and power tools. Construction-carpentry trainees also participate in calisthenics to prepare for the physical aspect of the work. Upon completion of pre-apprenticeship, trainees who have passed the graded curriculum (taught by highly experienced journeyperson carpenters) are assigned to a local union and to union carpentry crews at work on construction sites or in cabinet shops as First Year Apprentices. Over the next four years, as they progress in status to Second Year, Third Year, and Fourth Year Apprentice, apprentices periodically return to the training facility every three months for a week of more detailed training in specific aspects of the trade. In the United States, fewer than 5% of carpenters identify as female.

Architecture is the study and practice of designing structures, especially habitable ones. It utilizes civil engineering techniques, but is considered a visual art. It is both the process and the product of sketching, conceiving, planning, designing, and constructing buildings or other structures. The term comes from Latin architectura; from Ancient Greek ἀρχιτέκτων (arkhitéktōn) 'architect'; from ἀρχι- (arkhi-) 'chief' and τέκτων (téktōn) 'creator'. Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements. The practice of architecture itself, which began in the prehistoric era, has been used as a way of expressing culture by civilizations on all seven continents. For this reason, architecture is considered to be a form of art. Texts on architecture have been written since ancient times. The earliest surviving text on architectural theories is the 1st century BC treatise De architectura by the Roman architect Vitruvius, according to whom a good building embodies firmitas, utilitas, and venustas (durability, utility, and beauty). Centuries later, Leon Battista Alberti developed his ideas further, seeing beauty as an objective quality of buildings to be found in their proportions. In the 19th century, Louis Sullivan declared that "form follows function". "Function" began to replace the classical "utility" and was understood to include not only practical but also aesthetic, psychological, and cultural dimensions. The idea of sustainable architecture was introduced in the late 20th century. Architecture began as rural, oral vernacular architecture that developed from trial and error to successful replication. Ancient urban architecture was preoccupied with building religious structures and buildings symbolizing the political power of rulers until Greek and Roman architecture shifted focus to civic virtues. Indian and Chinese architecture influenced forms all over Asia and Buddhist architecture in particular took diverse local flavors. During the Middle Ages, pan-European styles of Romanesque and Gothic cathedrals and abbeys emerged while the Renaissance favored Classical forms implemented by architects known by name. Later, the roles of architects and engineers became separated. Modern architecture began after World War I as an avant-garde movement that sought to develop a completely new style appropriate for a new post-war social and economic order focused on meeting the needs of the middle and working classes. Emphasis was put on modern techniques, materials, and simplified geometric forms, paving the way for high-rise superstructures. Many architects became disillusioned with modernism which they perceived as ahistorical and anti-aesthetic, and postmodern and contemporary architecture developed.

Apprenticeship is a system for training potential new practitioners of a trade or profession with on-the-job training and often some accompanying study. Apprenticeships may also enable practitioners to gain a license to practice in a regulated occupation. Most of their training is done while working for an experienced employer who helps the apprentices learn their trade or profession, in exchange for their continued labor for an agreed period after they have achieved measurable competencies. Apprenticeship lengths vary significantly across sectors, professions, roles and cultures. In some cases, people who successfully complete an apprenticeship can reach the "journeyman" or professional certification level of competence. In other cases, they can be offered a permanent job at the company that provided the placement.

istrative unit. These projects may be completed by a private developer, (quasi-) governmental agency, or a combination thereof. A mixed-use development may be a new construction, reuse of an existing building or brownfield site, or a combination. Use in North America vs. Europe Traditionally, human settlements have developed in mixed-use patterns. However, with industrialization, governmental zoning regulations were introduced to separate different functions, such as manufacturing, from residential areas. Public health concerns and the protection of property values stood as the motivation behind this separation. In the United States, the practice of zoning for single-family residential use was instigated to safeguard communities from negative externalities, including air, noise, and light pollution, associated with heavier industrial practices. These zones were also constructed because of racial and class tensions. The heyday of separate-use zoning in the United States came after World War II when planner and New York City Parks Commissioner, Robert Moses, championed superhighways to break up functions and neighborhoods of the city. The antithesis to these practices came from activist and writer, Jane Jacobs, who was a major proponent of mixed-use zoning, believing it played a key role in creating an organic, diverse, and vibrant streetscape. These two figures went head-to-head during much of the 1960s. Since the 1990s, mixed-use zoning has once again become desirable as it works to combat urban sprawl and increase economic vitality. In most of Europe, government policy has encouraged the continuation of the city center's role as a main location for business, retail, restaurant, and entertainment activity, unlike in the United States where zoning actively discouraged such mixed use for many decades. In England, for example, hotels are included under the same umbrella as "residential," rather than commercial as they are classified under in the US. France similarly gravitates towards mixed-use as much of Paris is simply zoned to be "General Urban," allowing for a variety of uses. Even zones that house the mansions and villas of the aristocrats focus on historical and architectural preservation rather than single family zoning. Single family zoning is also absent in Germany and Russia where zoning codes make no distinction between different types of housing. America's attachment to private property and the traditional 1950s suburban home, as well as deep racial and class divides, have marked the divergence in mixed-use zoning between the continents.

Contexts Expanded use of mixed-use zoning and mixed-use developments may be found in a variety of contexts, such as the following (multiple such contexts might apply to one particular project or situation): as part of smart growth planning strategies in traditional urban neighborhoods, as part of urban renewal and/or infill, i.e., upgrading the buildings and public spaces and amenities of the neighborhood to provide more and/or better housing and a better quality of life—examples include Barracks Row in Washington, D.C., and East Liberty, Pittsburgh in traditional suburbs, adding one or more mixed-use developments to provide a new or more prominent "downtown" for the community–examples include new projects in downtown Bethesda, Maryland, an inner suburb of Washington, D.C., and the Excelsior & Grand complex in St.

anking countries for 2022 were Mainland China, India, Canada, Brazil, and Sweden. LEED Canada has developed a separate rating system adapted to the Canadian climate and regulations. Many U.S. federal agencies, state and local governments require or reward LEED certification. As of 2022, based on certified square feet per capita, the leading five states (after the District of Columbia) were Massachusetts, Illinois, New York, California, and Maryland. Incentives can include tax credits, zoning allowances, reduced fees, and expedited permitting. Offices, healthcare-, and education-related buildings are the most frequent LEED-certified buildings in the US (over 60%), followed by warehouses, distribution centers, retail projects and multifamily dwellings (another 20%). Studies have found that for-rent LEED office spaces generally have higher rents and occupancy rates and lower capitalization rates. LEED is a design tool rather than a performance-measurement tool and has tended to focus on energy modeling rather than actual energy consumption. It has been criticized for a point system that can lead to inappropriate design choices and the prioritization of LEED certification points over actual energy conservation; for lacking climate specificity; for not sufficiently addressing issues of climate change and extreme weather; and for not incorporating principles of a circular economy. Draft versions of LEED v5 were released for public comment in 2024, and the final version of LEED v5 appeared in April 2025. It may address some of the previous criticisms. Despite concerns, LEED has been described as a "transformative force in the design and construction industry".

Fedrizzi served as the volunteer founding chair of USGBC from 1993 to 2004, and became its CEO as of 2004. As of November 4, 2016, he was succeeded as president and CEO of USGBC by Mahesh Ramanujam. Ramanujam served as CEO until 2021. Peter Templeton became interim president and CEO of USGBC as of November 1, 2021. A key player in developing the Leadership in Energy and Environmental Design (LEED) green certification program was Natural Resources Defense Council (NRDC) senior scientist Robert K. Watson. It was Watson, sometimes referred to as the "Founding Father of LEED", who created the acronym. Over two decades, Watson led a broad-based consensus process, bringing together non-profit organizations, government agencies, architects, engineers, developers, builders, product manufacturers and other industry leaders. The original planning group consisted of Watson, Mike Italiano, architect Bill Reed (founding LEED Technical Committee co-chair 1994–2003), architect Sandy Mendler, builder Gerard Heiber and engineer Richard Bourne. Tom Paladino and Lynne Barker (formerly King) co-chaired the LEED Pilot Committee from 1996–2001. Scot Horst chaired the LEED Steering Committee beginning in 2005 and was deeply involved in the development of LEED 2009. Joel Ann Todd took over as chair of the steering committee from 2009 to 2013, working to develop LEED v4, and introducing social equity credits. Other steering committee chairs include Chris Schaffner (2019) and Jennifer Sanguinetti (2020). Chairs of the USGBC's Energy and Atmosphere Technical Advisory Group for LEED technology have included Gregory Kats. The LEED initiative has been strongly supported by the USGBC Board of Directors, including Chair of the Board of Directors Steven Winter (1999–2003).

uildings. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate governmental or private authority. Building codes are generally intended to be applied by architects, engineers, interior designers, constructors and regulators but are also used for various purposes by safety inspectors, environmental scientists, real estate developers, subcontractors, manufacturers of building products and materials, insurance companies, facility managers, tenants, and others. Codes regulate the design and construction of structures where adopted into law. Examples of building codes began in ancient times. In the USA the main codes are the International Building Code or International Residential Code [IBC/IRC], electrical codes and plumbing, mechanical codes. Fifty states and the District of Columbia have adopted the I-Codes at the state or jurisdictional level. In Canada, national model codes are published by the National Research Council of Canada. In the United Kingdom, compliance with Building Regulations is monitored by building control bodies, either Approved Inspectors or Local Authority Building Control departments.

Types The practice of developing, approving, and enforcing building codes varies considerably among nations. In some countries building codes are developed by the government agencies or quasi-governmental standards organizations and then enforced across the country by the central government. Such codes are known as the national building codes (in a sense they enjoy a mandatory nationwide application). In other countries, where the power of regulating construction and fire safety is vested in local authorities, a system of model building codes is used. Model building codes have no legal status unless adopted or adapted by an authority having jurisdiction. The developers of model codes urge public authorities to reference model codes in their laws, ordinances, regulations, and administrative orders. When referenced in any of these legal instruments, a particular model code becomes law. This practice is known as 'adoption by reference'. When an adopting authority decides to delete, add, or revise any portions of the model code adopted, it is usually required by the model code developer to follow a formal adoption procedure in which those modifications can be documented for legal purposes. There are instances when some local jurisdictions choose to develop their own building codes. At some point in time all major cities in the United States had their own building codes. However, due to ever increasing complexity and cost of developing building regulations, virtually all municipalities in the country have chosen to adopt model codes instead. For example, in 2008 New York City abandoned its proprietary 1968 New York City Building Code in favor of a customized version of the International Building Code. The City of Chicago remains the only municipality in America that continues to use a building code the city developed on its own as part of the Municipal Code of Chicago. In Europe, the Eurocode: Basis of structural design, is a pan-European building code that has superseded the older national building codes. Each country now has National Annexes to localize the contents of the Eurocodes. Similarly, in India, each municipality and urban development authority has its own building code, which is mandatory for all construction within their jurisdiction.

Real estate development is the process of acquiring land or existing property, improving it through planning and construction, and selling or leasing for profit. It involves coordinating design, financing, approvals, construction, and marketing. Developers assume significant risk in exchange for potential returns and may oversee projects ranging from residential housing to commercial and mixed-use developments. Developers acquire land, arrange financing, obtain regulatory approvals, and oversee construction or renovation. Developers usually take significant financial risks in the creation or renovation of real estate and receive the greatest rewards. Typically, developers purchase a tract of land, determine the marketing of the property, develop the building program and design, obtain the necessary public approval and financing, build the structures, and rent out, manage, and ultimately sell it. Real estate development has been criticized for contributing to urban sprawl and environmental degradation. Supporters argue that development expands housing supply, reduces housing costs, stimulates economic growth and creates jobs.

Some developers only handle part of the process. For example, some developers source a property and get the plans and permits approved before selling the property with the plans and permits to a builder at a premium price. Alternatively, a developer who is also a builder may purchase a property with the plans and permits in place so that they do not have the risk of failing to obtain planning approval and can start construction on the development immediately. Financial difficulties in development and investing differ because of leverage. Developers work with many different counterparts along each step of this process, including architects, city planners, engineers, surveyors, inspectors, contractors, lawyers, leasing agents, etc. In the Town and Country Planning context in the United Kingdom, “development” is defined in the Town and Country Planning Act 1990 s55. Organizing for development Development teams vary in size, bigger companies may provide all services in-house. At the other end of the spectrum, a development company might consist of one principal and a few staff who hire or contract with other companies and professionals for each service as needed. Assembling a team of professionals to address the environmental, economic, private, physical and political issues inherent in a complex development project is critical. A developer's success depends on the ability to coordinate and lead the completion of a series of interrelated activities efficiently and at the appropriate time. Development process requires skills of many professionals: architects, landscape architects, civil engineers and site planners to address project design; market consultants to determine demand and a project's economics; attorneys to handle agreements and government approvals; environmental consultants and soils engineers to analyze a site's physical limitations and environmental impacts; surveyors and title companies to provide legal descriptions of a property; and lenders to provide financing.

Interior design is the art and science of enhancing the interior of a building to achieve a healthier and more aesthetically pleasing environment for the people using the space. With a keen eye for detail and a creative flair, an interior designer is someone who plans, researches, coordinates, and manages such enhancement projects. Interior design is a multifaceted profession that includes conceptual development, space planning, site inspections, programming, research, communicating with the stakeholders of a project, construction management, and execution of the design.

ramming, research, communicating with the stakeholders of a project, construction management, and execution of the design. Interior designers make use of fundamental design principles from the visual arts used to help viewers understand a given scene. History and current terms In the past, interiors were put together instinctively as a part of the process of building. The profession of interior design has been a consequence of the development of society and the complex architecture that has resulted from the development of industrial processes. The pursuit of effective use of space, user well-being and functional design has contributed to the development of the contemporary interior design profession. The profession of interior design is separate and distinct from the role of interior decorator, a term commonly used in the US; the term is less common in the UK, where the profession of interior design is still unregulated and therefore, strictly speaking, not yet officially a profession. In ancient India, architects would also function as interior designers. This can be seen from the references of Vishwakarma the architect—one of the gods in Indian mythology. In these architects' design of 17th-century Indian homes, sculptures depicting ancient texts and events are seen inside the palaces, while during the medieval times wall art paintings were a common feature of palace-like mansions in India commonly known as havelis. While most traditional homes have been demolished to make way to modern buildings, there are still around 2000 havelis in the Shekhawati region of Rajasthan that display wall art paintings. In ancient Egypt, "soul houses" (or models of houses) were placed in tombs as receptacles for food offerings.

nd surface in ponds and puddles, evaporate back into the atmosphere, or contribute to surface runoff. Most runoff is conveyed directly as surface water to nearby streams, rivers or other large water bodies (wetlands, lakes and oceans) without treatment. In natural landscapes, such as forests, soil absorbs much of the stormwater. Plants also reduce stormwater by improving infiltration, intercepting precipitation as it falls, and by taking up water through their roots. In developed environments, such as cities, unmanaged stormwater can create two major issues: one related to the volume and timing of runoff (flooding) and the other related to potential contaminants the water is carrying (water pollution). In addition to the pollutants carried in stormwater runoff, urban runoff is being recognized as a cause of pollution in its own right. Stormwater is also an important resource as human population and demand for water grow, particularly in arid and drought-prone climates.

With less vegetation and more impervious surfaces (parking lots, roads, buildings, compacted soil), developed areas allow less rain to infiltrate into the ground, and more runoff is generated than in undeveloped conditions. Additionally, passages such as ditches and storm sewers quickly transport runoff away from commercial and residential areas into nearby water bodies. This greatly increases the volume of water in waterways and the discharge of those waterways, leading to erosion and flooding. Because the water is flushed out of the watershed during the storm event, little infiltrates the soil, replenishes groundwater, or supplies stream baseflow in dry weather. A first flush is the initial runoff of a rainstorm. During this phase, polluted water entering storm drains in areas with high proportions of impervious surfaces is typically more concentrated compared to the remainder of the storm. Consequently, these high concentrations of urban runoff result in high levels of pollutants discharged from storm sewers to surface waters. Daily human activities result in deposition of pollutants on roads, lawns, roofs, farm fields, and other land surfaces. Such pollutants include trash, sediment, nutrients, bacteria, pesticides, metals, and petroleum byproducts. When it rains or there is irrigation, water runs off and ultimately makes its way to a river, lake, or ocean.

In the United States, the Environmental Protection Agency (EPA) is charged with regulating stormwater pursuant to the Clean Water Act (CWA). The goal of the CWA is to restore all "Waters of the United States" to their "fishable" and "swimmable" conditions. Point source discharges, which originate mostly from municipal wastewater (sewage) and industrial wastewater discharges, have been regulated since enactment of the CWA in 1972. Pollutant loadings from these sources are tightly controlled through the issuance of National Pollution Discharge Elimination System (NPDES) permits. However, despite these controls, thousands of water bodies in the U.S. remain classified as "impaired," meaning that they contain pollutants at levels higher than is considered safe by EPA for the intended beneficial uses of the water. Much of this impairment is due to polluted runoff, generally in urbanized watersheds (in other US watersheds, agricultural pollution is a major source). To address the nationwide problem of stormwater pollution, Congress broadened the CWA definition of "point source" in 1987 to include industrial stormwater discharges and Municipal Separate Storm Sewer Systems ("MS4"). These facilities are required to obtain NPDES permits.

Historic preservation (US), built heritage preservation or built heritage conservation (UK) is an endeavor that seeks to preserve, conserve and protect buildings, objects, landscapes or other artifacts of historical significance. It is a philosophical concept that became popular in the twentieth century, which maintains that cities as products of centuries' development should be obligated to protect their patrimonial legacy.

In 1790, Aubin-Louis Millin submitted a report to the Constituent Assembly regarding the demolition of the Bastille, using the term "monument historique" (transl. historic monument). The idea of preserving sites linked to the Ancien régime and earlier circulated as a result, and under impetus of Talleyrand, the Assembly, on the 13th of October, created the commission des monuments (transl. Commission of Monuments) whose function was to "study the fate of monuments, arts, and sciences." The following year, Alexandre Lenoir was appointed to create the Musée des Monuments français (transl. Museum of French Monuments), which opened in 1795 and exhibited fragments of architecture Lenoir had saved and salvaged from destruction over the previous years. The museum was ultimately closed during the Restoration by Louis XVIII, and its collection was returned to the original owners and their families. The vandalism and widespread destruction which accompanied the French Revolution had inspired several such responses, and the first known register of such buildings was an inventory of the castles begun by Louis XVI by the conseil des bâtiments civils (transl. Council of Civil Buildings), which was completed in 1795. Between 1804 and 1834, several archaeological societies were formed, notably the Société des antiquaires de France in 1804 (originally the Académie celtique), the Société française d'archéologie in 1834, and the Comité des travaux historiques et scientifiques also in 1834. In 1819, the Ministry of the Interior provided an allowance for monuments historiques for the first time, and, on 21 October 1830, François Guizot (then Minister of the Interior) proposed the creation of a post, the Inspector General of Historic Monuments, to classify buildings and distribute funds for their preservation. This post was first assigned to Ludovic Vitet on 25 November 1830, and later to Prosper Mérimée on 27 May 1834. In 1837, Bachasson, in his capacity of Minister of the Interior, officially established the Commission des monuments historiques (transl. Commission for Historic Monuments) to carry out the work of classification and producing an inventory, as well as distributing funding and training architects for restoration work (Eugène Viollet-le-Duc among them). The Commission published its first inventory in 1840, and subsequently continued its inventory work, as well as create visual records for any future restoration. To this end, it created the Mission Héliographique to photograph monuments in 1851. During this period, the combination of reluctance to understand the government's prerogatives and the fact that the classification of private property required the owners' consent resulted in the gradual decrease in the number of registered monuments. On 2 May 1887, a law was passed establishing procedures for the classification of historic monuments as well as establish provisions for a body of Architecte en chef des monuments historiques for their upkeep. In 1906, French law laid down principles of classification of natural sites. Under the 1905 Law of Separation of Church and State, local communities and the government were entrusted with the care and upkeep of religious buildings, however, this led to refusal to care for buildings not of "national interest" by some and the auctioning off of heritage by others. Per consequence, on 13 December 1913, a law was passed which widened the field of protection for classified monuments, including changing "national interest" to "public interest" and allowing the classification of private property without the consent of the owner. During the 1920s and 1930s, classification further opened up to private property; additionally, monuments post-dating the Ancien régime began to be classified. In 1925, a second order of classification was introduced: inscription à l'inventaire supplémentaire des monuments historiques (transl. inscription in the supplementary inventory of historical monuments). In 1930, the classifications were renamed "classé" and "inscrit" (transl. "classified" and "registered") and classification was allowed to include the land immediately surrounding a classified building.

By the mid 19th century, much of Britain's unprotected cultural heritage was being slowly destroyed. Even well-meaning archaeologists like William Greenwell excavated sites with virtually no attempt at their preservation, Stonehenge came under increasing threat by the 1870s. Tourists were chipping off parts of the stones or carving their initials into the rock. The private owners of the monument decided to sell the land to the London and South-Western Railway who stated that the monument was "not the slightest use to anyone now". John Lubbock, an MP and botanist emerged as the champion of the country's national heritage. In 1872 he personally bought private land that housed ancient monuments in Avebury, Silbury Hill and elsewhere, from the owners who were threatening to have them cleared away to make room for housing. Soon, he began campaigning in Parliament for legislation to protect monuments from destruction. This finally led to the legislative milestone under the Liberal government of William Gladstone of the Ancient Monuments Protection Act 1882. The first government appointed inspector for this job was the archaeologist Augustus Pitt-Rivers. This legislation was regarded by conservative political elements as a grave assault on the individual rights of property of the owner, and consequently, the inspector only had the power to identify endangered landmarks and offer to purchase them from the owner with his consent. The Act only covered ancient monuments and explicitly did not cover historic buildings or structures. In 1877 the Society for the Protection of Ancient Buildings was founded by the Arts and Crafts designer William Morris to prevent the destruction of historic buildings, followed by the National Trust in 1895 that bought estates from their owners for preservation. The Ancient Monuments Protection Act 1882 had only given legal protection to prehistoric sites, such as ancient tumuli. The Ancient Monuments Protection Act 1900 took this further by empowering the government's Commissioners of Work and local County Councils to protect a wider range of properties.

ern Oregon to Boise, and is the most populated area in Idaho. Historically, the valley had been known as the Lower Snake River Valley or the Boise River Valley. Pete Olesen, president of the valley's association of local Chambers of Commerce, coined the name "Treasure Valley" in 1959 to reflect the treasure chest of resources and opportunities that the region offered. The valley has a very diverse terrain, from sage flatlands, to mesas, agricultural areas, and urbanized areas.

The Treasure Valley is a valley in the western United States, primarily in southwestern Idaho, where the Payette, Boise, Weiser, Malheur, and Owyhee rivers drain into the Snake River. It includes all the lowland areas from Vale in rural eastern Oregon to Boise, and is the most populated area in Idaho.

eflect the treasure chest of resources and opportunities that the region offered. The valley has a very diverse terrain, from sage flatlands, to mesas, agricultural areas, and urbanized areas. As the Boise Metropolitan Area grows, more and more undeveloped and agricultural land is being urbanized. History Settling the region The tribes that roamed the area, specifically, were the Northern Paiute and Shoshone. In 1834, Thomas McKay built the original Fort Boise, in the area near present-day Parma, which was run for a time by Francois Payette. It later was moved because of flooding troubles and was abandoned in 1854. The Oregon Trail runs through the Treasure Valley. The valley was settled for the most part by ranchers and farmers, initially to supply the gold and silver mining communities in the higher elevations nearby: Idaho City in the Boise Basin and Silver City in the Owyhees. A new Fort Boise was constructed by the U.S. Army in 1863 in present-day Boise, from which the city grew.

Meridian is a city located in Ada County, Idaho, United States. The population was 117,635 at the 2020 census, making it the second most populous city in the county and Idaho, after Boise, the state capital.

Rail transportation (1908–28) Following the raising of $4,000 to lay the Interurban rail line from Onweiler (Meridian and Ustick Roads), the tracks were completed into the village center. Turning east on Broadway and ending at East Second, the last car would spend the night in Meridian before returning to Boise early the next morning with passengers and freight. The interurban Station and Generator building (west one-third of the old library at Meridian and Idaho Streets) was built in 1912, and the line continued on to Nampa via Meridian. The tracks down Broadway were not used after 1912. The Interurban Company entered into receivership and closed in 1928 after 20 years of providing continuous transportation to neighboring towns. It was Meridian's main connection to the area outside the local community. The Union Pacific Railroad spur opened in 1900 and is currently operated by the Boise Valley Railroad. Many industrial customers continue to ship forest, agricultural, and chemical products along this corridor. Creamery (1929–70) The city's official website describes the history of the Ada County Dairymen's cooperative creamery as follows:The lowest days of the Great Depression brightened for area dairymen when the Ada County Dairymen's cooperative creamery began operation in 1929. It provided milk checks to those who were members of the cooperative, enabling them to pay their taxes and provide food for their families. Other community members hauled milk to the creamery and were employed by the creamery, whose product was Challenge Butter. The creamery ran seven days a week for 40 years. Additions and improvements were made while the plant was in full operation. Later years saw the Wyeth Laboratories affiliate with the creamery to manufacture SMA baby formula.

are increased commercial investments in the area and its infrastructure by real estate developers, local government, or community activists and resulting economic development, increased attraction of business, and lower crime rates. Origin and etymology Historians say that gentrification took place in ancient Rome and in Roman Britain, where large villas were replacing small shops by the 3rd century CE. The word gentrification derives from gentry—which comes from Old French genterise, "of gentle birth" (14th century) and "people of gentle birth" (16th century). In England, landed gentry denoted the social class, consisting of gentlemen and gentlewomen (as the latter were known at that time). A more direct derivational base of gentrification is the 19th-century neologism "gentrify," a verb coined by Samuel Laing (1780–1868). This term reflected shifting societal attitudes—specifically, the idea that one could attain upper-class status through conduct rather than birth—while also introducing undertones of conspicuous consumption and pretentiousness. The British sociologist Ruth Glass was the first to use "gentrification" in its current sense.

demographic-ecological: dual white-collar wage-earner households with fewer children wanted to live closer to work and thus moved to the inner city; sociocultural: middle- and upper-middle-class families developed more pro-urban views, opting to live in urban areas; political-economical: the decreasing availability of suburban land prompted more high-income individuals to live in urban areas; community networks: technological advances in transportation and communication prompts more people to live in large-scale communities; social movements: when high status elites and institutions sought to revive the inner cities, more high-income individuals moved into the cities. Other explanations propose that as people tire of the automobile-dependent urban sprawl style of life, they move to urban areas, in particular to homes near public transit stations. The increase in professional jobs in the central business district has increased demand for living in urban areas according to Ley (1980). Critical geographers have argued that capital flows and developers have been instrumental in causing gentrification. The de-industrialization of cities in developed nations may have caused displacement by reducing the number of blue-collar jobs available to the urban working class and middle-class. Some have argued that the counterculture movement in the 1960s created disdain for the "standardization of look-alike suburbs", prompting people to live in urban areas.

Many of the social effects of gentrification have been based on extensive theories about how socioeconomic status of an individual's neighborhood will shape one's behavior and future. These studies have prompted "social mix policies" to be widely adopted by governments to promote the process and its positive effects, such as lessening the strain on public resources that are associated with de-concentrating poverty. However, more specific research has shown that gentrification does not necessarily correlate with "social mixing", and that the effects of the new composition of a gentrified neighborhood can both weaken as well as strengthen community cohesion. Housing confers social status, and the changing norms that accompany gentrification translate to a changing social hierarchy. The process of gentrification mixes people of different socioeconomic strata, thereby congregating a variety of expectations and social norms. The change gentrification brings in class distinction also has been shown to contribute to residential polarization by income, education, household composition, and race. It conveys a social rise that brings new standards in consumption, particularly in the form of excess and superfluity, to the area that were not held by the pre-existing residents. These differing norms can lead to conflict, which potentially serves to divide changing communities. Often this comes at a larger social cost to the original residents of the gentrified area whose displacement is met with little concern from the gentry or the government. Clashes that result in increased police surveillance, for example, would more adversely affect young minorities who are also more likely to be the original residents of the area. There is also evidence to support that gentrification can strengthen and stabilize when there is a consensus about a community's objectives. Gentrifiers with an organized presence in deteriorated neighborhoods can demand and receive better resources. A characteristic example is a combined community effort to win historic district designation for the neighborhood, a phenomenon that is often linked to gentrification activity. Gentry can exert a peer influence on neighbors to take action against crime, which can lead to even more price increases in changing neighborhoods when crime rates drop and optimism for the area's future climbs. Some argue that gentrification is associated with the decline of distinctive local businesses and the rise of chains and franchises. Rehabilitation movements have been largely successful at restoring the plentiful supply of old and deteriorated housing that is readily available in inner cities. This rehabilitation can be seen as a superior alternative to expansion, for the location of the central city offers an intact infrastructure that should be taken advantage of: streets, public transportation, and other urban facilities. Furthermore, the changed perception of the central city that is encouraged by gentrification can be healthy for resource-deprived communities who have previously been largely ignored.

Planning permission or building permit refers to the approval needed for construction or expansion (including significant renovation), and sometimes for demolition, in some jurisdictions. House building permits, for example, are subject to building codes. There is also a "plan check" (PLCK) to check compliance with plans for the area, if any. For example, one cannot obtain permission to build a nightclub in an area where it is inappropriate such as a high-density suburb. The criteria for planning permission are a part of urban planning and construction law, and are usually managed by town planners employed by local governments. Failure to obtain a permit can result in fines, penalties, and demolition of unauthorized construction if it cannot be made to meet code. Generally, the new construction must be inspected during construction and after completion to ensure compliance with national, regional, and local building codes. Since building permits usually precede outlays for construction, employment, financing and furnishings, they are often used as a leading indicator for development in other areas of the economy. The number of building permits issued per year varies by country.

By-right approval processes can be faster than discretionary approval processes. In specific industries Broadcasting As part of broadcast law, the term is also used in broadcasting, where individual radio and television stations typically must apply for and receive permission to construct radio towers and radio antennas. This type of permit is issued by a national broadcasting authority, but does not imply zoning any other permission that must be given by local government. The permit itself also does not necessarily imply permission to operate the station once constructed. In the U.S., a construction permit is valid for three years. Afterwards, the station must receive a full license to operate, which is good for seven years. This is provided by a separate broadcast license, also called a "license to cover" by the Federal Communications Commission (FCC) in the United States. Further permission or registration for towers may be needed from aviation authorities. In the U.S., construction permits for new commercial stations are now assigned by auction, rather than the former process of determining who would serve the community of license best.

ized construction if it cannot be made to meet code. Generally, the new construction must be inspected during construction and after completion to ensure compliance with national, regional, and local building codes. Since building permits usually precede outlays for construction, employment, financing and furnishings, they are often used as a leading indicator for development in other areas of the economy. The number of building permits issued per year varies by country.

Building information modeling (BIM) is an approach involving the generation and management of digital representations of the physical and functional characteristics of buildings or other physical assets and facilities. BIM is supported by various tools, processes, technologies and contracts. Building information models (BIMs) are computer files (often but not always in proprietary formats and containing proprietary data) which can be extracted, exchanged or networked to support decision-making regarding a built asset. BIM software is used by individuals, businesses and government agencies who plan, design, construct, operate and maintain buildings and diverse physical infrastructures, such as water, refuse, electricity, gas, communication utilities, roads, railways, bridges, ports and tunnels.

Boise (locally also ) is the capital and most populous city in the U.S. state of Idaho. It is the county seat of Ada County. The population of the city was 235,685 at the 2020 census. The Boise metropolitan area, located in the Treasure Valley, includes five counties of Idaho with an estimated population of 846,000, the most populous metropolitan area in Idaho and 95th-most populous in the United States. Located on the Boise River in southwestern Idaho, it is 41 miles (66 km) east of the Oregon border and 110 miles (177 km) north of the Nevada border. Downtown Boise's elevation is 2,704 feet (824 m) above sea level. Boise is home to major employers in the technology, manufacturing, and service sectors, including companies such as Micron Technology and Hewlett-Packard.

...that the military should continue killing Indians 'until the last Indian in the Territories was either on his reservation or enriched the sagebrush with his decaying carcass.' ...if the Indians refused to move there, 'they will be killed or put on the reservation by force, and certainly shot if they don't stay there.' Furthermore, the editor continues, 'The idea that the Indians have any right to the soil is ridiculous. ...They have no more rights to the soil of the Territories of the United States than wolves or coyotes...' This would be our plan of establishing friendship upon an eternal basis with our Indians: Let all the hostile bands of Idaho Territory be called in (they will not be caught in any other manner) to attend a grand treaty; plenty of blankets and nice little trinkets distributed among them; plenty of grub on hand; have a real jolly time with them; then just before the big feast put strychnine in their meat and poison to death the last mother's son of them. At the same time, native warriors around the valley, under the leadership of Howluck also known as "Bigfoot" among white settlers, among others, waged an escalating and intensified guerrilla campaign of harassment of passerby caravans along the Oregon Trail. The United States Army also escalated and intensified "punitive expeditions" against formations of warriors and against civilian communities as well. This marked the start of the "unofficial" Snake War in 1866. This war lasted until 1868, and is statistically the deadliest of the Indian Wars in the West in terms of casualties. In the end, 1,762 men were counted as the casualties of this war from both sides. In 1868, Fort Hall Indian Reservation was established in Southeastern Idaho, about 220 miles upstream, according to the terms of Fort Bridger Treaty. The Boise Valley Shoshone and Bannock Tribes were not party to this treaty. Nevertheless, in April 1869, the United States Military embarked on a campaign of "Removal, rounding up of natives in the region including in and around Boise, and expelling them with cavalry escort to Fort Hall Indian Reservation. This period is known among the Shoshone and Bannock people as Idaho's Trail of Tears. Some of the natives managed to escape, and they ran to either Duck Valley or Fort McDermitt in Nevada. Incorporation and growth Boise's early growth was significantly driven by its role in supplying the nearby gold towns that sprung up in the 1860s northeast and then southwest of the town. Miners sometimes wintered in Boise and a number of early prominent businessmen were miners who settled in town in the years after the gold rush waned. By 1864 substantial agricultural production was underway on easily irrigated lands near the river and three canal companies had been incorporated. Early transportation improvements were largely a result of toll road franchises awarded by the territorial legislature starting in the 1860s. These first ran from Fort Boise to the mining centers in the Boise Basin and east to Rocky Bar and to Rattlesnake Station where they connected to the Oregon Trail. Territorial census records from a special 1864 enumeration list the population of Boise as 1,658, and an act of December 12, 1864, was the first attempt by the Idaho Territorial Legislature to incorporate the city. This was rejected by voters the following March. Two more unsuccessful attempts were made to organize a city administration by election before the 1866 version of the city charter was approved by voters on January 6, 1868. The growing number of homes and businesses, for which owners wanted proper legal title, may have contributed to the eventual success of incorporation. All of these rejected efforts to incorporate the city came after Boise had been controversially made the state capital in 1864 over strong opposition from northern Idaho interests. This decision reflected the rapid shift of population growth from north to south after the discovery of gold in southern Idaho. By 1868 Boise had over 400 permanent buildings with a wide range of commercial services. 1868 also marked the formal beginning of a long advocacy for railroad connections to other Idaho communities and, just as importantly, to other growing cities in the west such as Portland, Oregon. Competing railroad and western state government interests frustrated these efforts for many years. Designed by Alfred B. Mullett, the U.S. Assay Office at 210 Main Street was built in 1871 and today is a National Historic Landmark. It first began accepting gold and silver for purchase on March 2, 1872, largely eliminating the need to transport ore to the mint in San Francisco. A territorial penitentiary, now known as the Old Idaho State Penitentiary, opened the same month several miles east of town. Mining continued to be important to Boise's economic growth and periodic booms contributed to population growth as well, though production of gold and silver probably peaked in the 1860s. 1882's gold and silver production of $3,500,000 declined to $1,488,315 (including lead) by 1899. Boise began to earn its City of Trees nickname in this period with a popular focus on a range of tree planting projects. Thomas J. Davis planted several thousand fruit trees in 1864 and several other early businessmen either founded nurseries or orchards of their own. In the 1870s tree planting began in earnest in downtown Boise led by prominent hotels as well as businessmen and residents. In 1907 Davis donated 43 acres of his orchard property to the city for use as a park in the name of his wife Julia. Commercial agriculture continued to expand, but was slowed by the lack of reliable rail links to regional and national markets and by a lack of large scale irrigation projects, which themselves were often tied to hoped-for railroad projects for financing. A.D. Foote, a successful mining engineer, drew up plans to irrigate up to 500,000 acres immediately south of Boise in 1882, but progress was halting and smaller farms were the norm until after the turn of the century with most located near to the river bottom where soil was productive and irrigation more easily achieved. Fruit orchards proliferated and sugar beets, still an important agricultural industry in Idaho, began to be widely cultivated in the 1890s. Cattle and sheep farming became increasingly important as the century closed. With the exception of dairy, most livestock products were exported from Idaho, unlike other agricultural products which were still largely scaled to support local markets. The timber industry also increasingly thrived in the Boise market in the 1880s and 1890s. Large quantities of timber were exported from elsewhere in Idaho, but a growing Boise supported the expansion of Alexander Rossi's sawmill, first established in 1865. Prominent early Boisean William Ridenbaugh had inherited control of the canal now bearing his name from his uncle William Morris in 1878 and later partnered with Rossi to expand the sawmill capacity under the name Rossi and Ridenbaugh Lumber Company. Their materials supported bridge building and the rapid expansion of Boise in the 1890s. As with many early infrastructure ventures, electrification succeeded only after at least one false start. July 4, 1887, marked the start of electrical transmission from a plant located on the Bench. William Ridenbaugh provided expertise and manpower for the water supply and several months were spent rigging poles and lines from the Bench to the service area across the river. Additional electrical supplies allowed the building of an electric streetcar line in 1891. This ran without interruption until buses replaced the lines in 1927, tracking—and sometimes driving—the development of Boise and nearby communities. This system expanded over several decades, reaching into the North End, South Boise and across the river on Front St. A loop line, completed in 1912, ran as far as Caldwell and Nampa, providing transport throughout the valley. Three early trolley companies merged in 1912 to form the Idaho Traction Company with a depot at 7th and Bannock Streets downtown. Additional services and urban amenities arrived in the 1890s as Boise grew. Exploratory drilling for hot water was successful in 1890 and by the end of the decade many homes along Warm Springs avenue were being heated by this source. A natatorium was built in 1892 close to the source of the hot water near the Idaho State Penitentiary. Churches serving several denominations, a Jewish synagogue, a major hardware store and department store, a Masonic hall, the Columbia Theater, Saint Alphonsus' Hospital, a number of parochial and secular schools, a City Hall and a new Union Pacific passenger station, constructed when service was finally extended to downtown, were all built during the 1890s. Falk's Department Store sponsored a semi-professional baseball team representing Boise from at least 1892 and the city supported other organized sports as they became popular.

the physical layout of human settlements. The primary concern was the public welfare, which included considerations of efficiency, sanitation, protection and use of the environment, as well as taking account of effects of the master plans on the social and economic activities. Over time, urban planning has adopted a focus on the social and environmental "bottom lines" that focuses on using planning as a tool to improve the health and well-being of people and maintain sustainability standards. In the mid-20th century, urban planning experts such as Jane Jacobs called on urban planners to take resident experiences and needs more into consideration. Urban planning answers questions about how people will live, work, and play in a given area and thus, guides orderly development in urban, suburban and rural areas. Although predominantly concerned with the planning of settlements and communities, urban planners are also responsible for planning the efficient transportation of goods, resources, people, and waste. The distribution of basic necessities such as water and electricity; a sense of inclusion and opportunity for people of all kinds, culture and needs; economic growth or business development; improving health and conserving areas of natural environmental significance that actively contribute to reduction in CO2 emissions as well as protecting heritage structures and built environments. Since most urban planning teams consist of highly educated individuals that work for city governments, recent debates focus on how to involve more community members in city planning processes. Urban planning is an interdisciplinary field that includes civil engineering, architecture, human geography, social science and design sciences. Practitioners of urban planning use research and analysis, strategic thinking, engineering architecture, urban design, public consultation, policy recommendations, implementation and management. It is closely related to the field of urban design and some urban planners provide designs for streets, parks, buildings and other urban areas. Urban planners work with the cognate fields of civil engineering, landscape architecture, architecture, and public administration to achieve strategic, policy and sustainability goals. Early urban planners were often members of these cognate fields though in the 21st century, urban planning is a separate, independent professional discipline. The discipline of urban planning is the broader category that includes different sub-fields such as land-use planning, zoning, economic development, environmental planning, and transportation planning. Creating the plans requires a thorough understanding of penal codes and zonal codes of planning. Another important aspect of urban planning is that projects range from the large-scale planning of new towns and Greenfield projects to the transformation and renewal of existing cities, neighborhoods, and public spaces. Pierre Charles L'Enfant and Lúcio Costa are known for planning new capital cities, while Daniel Burnham's Plan of Chicago, Georges-Eugene Haussmann's renovation of Paris, and the urban renewal projects of Robert Moses exemplify the large-scale reshaping of existing urban environments.

Technical aspects of urban planning involve the application of scientific, technical processes, considerations and features that are involved in planning for land use, urban design, natural resources, transportation, and infrastructure. Urban planning includes techniques such as: predicting population growth, zoning, geographic mapping and analysis, analyzing park space, surveying the water supply, identifying transportation patterns, recognizing food supply demands, allocating healthcare and social services, and analyzing the impact of land use. In order to predict how cities will develop and estimate the effects of their interventions, planners use various models. These models can be used to indicate relationships and patterns in demographic, geographic, and economic data. They might deal with short-term issues such as how people move through cities, or long-term issues such as land use and growth. One such model is the Geographic Information System (GIS) that is used to create a model of the existing planning and then to project future impacts on the society, economy and environment. Building codes and other regulations dovetail with urban planning by governing how cities are constructed and used from the individual level. Enforcement methodologies include governmental zoning, planning permissions, and building codes, as well as private easements and restrictive covenants. In urban planning, technical tools increasingly include incentive-based regulatory frameworks alongside zoning and building codes. Research on urban policies shows that financial, non-financial, and social incentives shape planning outcomes only when embedded in appropriate institutional and regulatory configurations. Rather than operating automatically, incentives interact with local rules, governance arrangements, and collective action capacities. Comparative urban studies highlight that effective planning depends on coordinated incentive systems, trust, monitoring mechanisms, and stakeholder co-production, rather than on isolated economic stimuli. This approach emphasizes the regulation of incentives themselves as a technical dimension of strategic urban planning. Recent advances in urban planning include the use of urban digital twins (UDTs), which leverage artificial intelligence (AI) and the Internet of Things (IoT) to simulate and predict urban development scenarios. These technologies enable planners to collect real-time data, predict population growth, traffic patterns, and assess the environmental impact of urban interventions.

States Department of Labor that originally had federal visitorial powers to inspect and examine workplaces. The United States Congress established the agency under the Occupational Safety and Health Act (OSH Act), which President Richard M. Nixon signed into law on December 29, 1970. OSHA's mission is to "assure safe and healthy working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education, and assistance". The agency is also charged with enforcing a variety of whistleblower statutes and regulations.

History From its creation in 1934, the Bureau of Labor Standards of the Department of Labor addressed some work safety issues. The economic boom and associated labor turnover during World War II worsened work safety in nearly all areas of the United States economy, but after 1945 accidents again declined as long-term forces reasserted themselves. Additionally, new and powerful labor unions played an increasingly important role in worker safety post-World War II. In the 1960s, increasing economic expansion again led to rising injury rates, and the resulting political pressures led Congress to establish the Occupational Safety and Health Administration (OSHA) on April 28, 1971, the date that the Occupational Health and Safety Act became effective. The new agency incorporated much of what had been the original Bureau of Labor Standards. George Guenther was appointed by Labor Secretary James D. Hodgson as the agency's first director. OSHA has run a number of training, compliance assistance, and health and safety recognition programs throughout its history. The OSHA Training Institute, which trains government and private sector health and safety personnel, began in 1972. In 1978, the agency began a grant-making program, now called the Susan Harwood Training Grant Program, to train workers and employers in reducing workplace hazards.

OSH Act coverage The OSH Act covers most private-sector employers and their workers, in addition to some public-sector employers and workers in the 50 states and certain territories and jurisdictions under federal authority. Those jurisdictions include the District of Columbia, Puerto Rico, the Virgin Islands, American Samoa, Guam, Northern Mariana Islands, Wake Island, Johnston Island, and the Outer Continental Shelf Lands as defined in the Outer Continental Shelf Lands Act. Private sector employers The OSH Act covers most private sector employers in all 50 states, the District of Columbia, and other U.S. jurisdictions—either directly through federal OSHA or through an OSHA-approved state plan. State plans are OSHA-approved job safety and health programs operated by individual states instead of federal OSHA. Federal OSHA approves and monitors all state plans and provides as much as fifty percent of the funding for each program.

jurisdiction and on the type of structure. In the United States, obtaining a certificate is generally required whenever: a new building is constructed a building built for one use is to be used for another (e.g., an industrial building converted for residential use) occupancy of a commercial or industrial building changes, or ownership of a commercial, industrial, or multiple-family residential building changes The purpose of obtaining a certificate of occupancy is to prove that, according to the law, the house or building is in liveable condition. Generally, such a certificate is necessary to be able to occupy the structure for everyday use, as well as to be able to sign a contract to sell the space and close on a mortgage for the space. A certificate of occupancy is evidence that the building complies substantially with the plans and specifications that have been submitted to, and approved by, the local authority.

Temporary certificate of occupancy (TCO) A temporary certificate of occupancy grants residents and building owners all of the same rights as a certificate of occupancy, however it is only for a temporary period of time. In New York City, TCOs are usually active for 90 days from the date of issue, after which they expire.

hod of procurement, the authors of Design-build Contracting Handbook noted that: "from a historical perspective the so-called traditional approach is actually a very recent concept, only being in use approximately 150 years.

the position that design–build can be led by a contractor, a designer, a developer or a joint venture, as long as a design–build entity holds a single contract for both design and construction, some architects have suggested that architect-led design–build is a specific approach to design–build. Design-build plays an important role in pedagogy, both at universities and in independently organised events such as Rural Studio or ArchiCamp.

Design–build contractor The "design–builder" is often a general contractor, but in many cases a project is led by a design professional (architect, engineer, architectural technologist or other professional designers). Some design–build firms employ professionals from both the design and construction sector. Where the design–builder is a general contractor, the designers are typically retained directly by the contractor. Partnership or a joint venture between a design firm and a construction firm may be created on a long-term basis or for one project only. Until 1979, the AIA American Institute of Architects' code of ethics and professional conduct prohibited their members from providing construction services. However today many architects in the United States and elsewhere aspire to provide integrated design and construction services, and one approach towards this goal is design–build. The AIA has acknowledged that design–build is becoming one of the main approaches to construction. In 2003, the AIA endorsed "The architect's guide to design–build services", which was written to help their members acting as design–build contractors.

floor 1. When space allocated to multiple functions is significant, these buildings can be called multi-use.

Commercial property, also called commercial real estate, investment property or income property, is real estate (buildings or land) intended to generate a profit, either from capital gains or rental income. Commercial property includes office buildings, medical centers, hotels, malls, retail stores, multifamily housing buildings, farm land, warehouses, and garages. In many U.S. states, residential property containing more than a certain number of units qualifies as commercial property for borrowing and tax purposes. Commercial buildings are buildings that are used for commercial purposes, and include office buildings, warehouses, and retail buildings (e.g. convenience stores, 'big box' stores, and shopping malls). In urban locations, a commercial building may combine functions, such as offices on levels 2–10, with retail on floor 1. When space allocated to multiple functions is significant, these buildings can be called multi-use.

Heating, ventilation, and air conditioning (HVAC ) systems regulate temperature, humidity, and indoor air quality in vehicles and buildings. They are designed to provide thermal comfort and to control airborne contaminants through heating, cooling, ventilation, filtration, and humidity control. HVAC design considerations include energy efficiency, indoor air quality, maintenance, and environmental impact, particularly in green building projects. In building design, mechanical, electrical, and plumbing engineers may integrate HVAC systems with other building systems (i.e.

Summary The three major functions of heating, ventilation, and air conditioning are intertwined. HVAC systems can provide ventilation and maintain pressure relationships between spaces. The means of air delivery and removal from spaces is known as room air distribution. Individual systems In modern buildings, the design, installation, and control systems of these functions are integrated into one or more HVAC systems. For very small buildings, contractors normally estimate the capacity and type of system needed and then design the system, selecting the appropriate refrigerant and various components needed. For larger buildings, building service designers, mechanical engineers, or building services engineers analyze, design, and specify the HVAC systems. Specialty mechanical contractors and suppliers then fabricate, install, and commission the systems.

pa ( ) is the most populous city in Canyon County, Idaho, United States. The population was 100,200 at the 2020 census. It is Idaho's third-most populous city. Nampa is about 20 miles (32 km) west of Boise along Interstate 84, and 6 miles (9.7 km) west of Meridian. It is the second principal city of the Boise metropolitan area. The name "Nampa" may have come from a Shoshoni word meaning 'moccasin' or 'footprint'. According to toponymist William O. Bright, the name comes from the Shoshoni word /nampai/, meaning "foot".

History Nampa had its beginnings in the early 1880s when the Oregon Short Line Railroad built a line from Granger, Wyoming, to Huntington, Oregon, that passed through Nampa. In Nampa there is a history museum that marks the railroad's significance. More railroad lines sprang up through Nampa, making it an important railroad town. Alexander and Hannah Duffes established one of the town's first homesteads, eventually forming the Nampa Land and Improvement Company with the help of their friend and co-founder, James McGee. Despite the name, many early settlers called the town "New Jerusalem" because of its citizens' strong religious focus. After only a year the town grew from 15 homes to 50. As amenities were added, Nampa continued to grow, and it was incorporated in 1891. Downtown Nampa's street grid is oriented with the railroad tracks, which run northwest–southeast; this was done intentionally by Alexander Duffes to prevent accidents like one that occurred earlier in a town he had platted near Toronto, where a woman and her two children were killed by a train when their buggy wheel got stuck as they crossed the tracks. As the Oregon Short Line railroad originally bypassed Boise, Nampa has the fanciest of many railroad depots built in the area. Nampa gained attention in 1889 due to a purported archaeological discovery known as the Nampa figurine. George Frederick Wright wrote up details that year for the Boston Society of Natural History. The first elementary school was built in the 1890s. Lakeview School was on a hill on 6th Street and 12th Avenue North, with a view of Lake Ethel. Just after the school's centennial celebration, it was condemned as a school and sold to the First Mennonite Church. In 2008 the building was refurbished, and it is now used by the Idaho Arts Charter School. Lake Ethel, an irrigation reservoir, had long been the site of community picnics, and many citizens fished, swam, boated, and even hunted on it and its surrounding property. But the hunting didn't last long, as O. F. Persons, owner of the adjoining homestead, took offense when local hunters started shooting his pet ducks. The city later auctioned off the lake. E. H. Dewey (a former Nampa mayor) was the only bidder. But occasional flooding led to a series of lawsuits from neighbors. Dewey eventually drained Lake Ethel. Not long after, the city council became interested in buying back the Fritz Miller property as well as the Dewey home. Pressure had been building for more than four years. Nampa citizens wanted another park. On August 7, 1924, the city council passed an ordinance to purchase the Miller property and name it Lakeview Park. A bandstand was completed in 1928, and the municipal swimming pool opened on August 13, 1934. It is Nampa's largest park and many community celebrations are held there. Colonel William H. Dewey, a man who made a fortune mining in Silver City, built the Dewey Palace Hotel in 1902 for $250,000. He died in his hotel in 1903, leaving his son $1 million. The hotel survived the great fire of 1909, which burned several blocks of downtown Nampa, but was razed in 1963 after redevelopment plans failed. Relics from the hotel such as the chandelier and the hotel safe can be found at the Canyon County Historical Museum, which is in the old train depot on Front Street and Nampa City Hall. After demolition the location on First Street between 11th and 12th Ave. South was sold to private enterprise, including a bank and tire store, replacing this building with modern structures. A public-use postage stamp sized park was later placed across the street from the old palace property as a collaboration between the Downtown Alliance of Nampa (the local business council) and an Eagle Scout Project for the Boy Scouts of America. The park includes a large mural/wall sculpture of running horses commissioned for the project. A Carnegie library was built downtown in 1908; it burned down after the library moved in 1966. Nampa Public Library was then on the corner of 1st Street and 11th Avenue South in the old bank building. A new library, on 12th Avenue South, opened in 2015. Deer Flat Reservoir, an offstream irrigation storage reservoir, was constructed by the United States Bureau of Reclamation between 1906 and 1911. Known locally as Lake Lowell, it is surrounded by the Deer Flat National Wildlife Refuge, established in 1909 by President Theodore Roosevelt. The refuge is administered by the U.S. Fish and Wildlife Service. Lake Lowell is filled by the concrete New York Canal; the water is diverted from the Boise River a few miles below Lucky Peak Dam. In 1910, the Idaho State School and Hospital was built northwest of Nampa for the state's developmentally challenged population. It opened in 1918. The institution was largely self-sufficient, with a large farm staffed by the residents. The higher-functioning residents also cared for residents who could not care for themselves. The land for the farm was sold and is now golf courses (Centennial and Ridgecrest), and the residents no longer give primary care to other residents. The institution is modernized and remains in operation, though a few of the oldest buildings now house juvenile offenders. Nampa held an annual harvest festival and farmers' market from about 1908, a time of celebration and community fun. From this festival emerged the Snake River Stampede Rodeo in 1937, which continues to this day. It is one of the top 12 rodeos in the pro rodeo circuits. In 1913, a local congregation of the Church of the Nazarene built a small elementary school, which became to Northwest Nazarene College in 1915 and finally Northwest Nazarene University. As of 2025, the university has approximately 1,800 undergraduate and graduate students. Karcher Mall opened in 1965, the first enclosed shopping mall in the Treasure Valley. It was "the place to gather" for several decades until the Boise Towne Square mall was built in Boise in 1988, drawing business away. Karcher Mall was renamed District 208 in 2022. The Idaho Press-Tribune is the local newspaper for the Canyon County area.

Idaho Hispanic Community Center (IH2C) In 2003, the Hispanic Cultural Center of Idaho (HCCI) opened thanks to community support. It has recently transitioned back to the City of Nampa and was renamed the Idaho Hispanic Community Center (IH2C) and is home to the Idaho Hispanic Foundation.

The American Institute of Architects (AIA) is a professional organization for architects in the United States. It is headquartered in Washington, D.C. AIA offers education, government advocacy, community redevelopment, and public outreach programs, and collaborates with other stakeholders in the design and construction industries..

stakeholders in the design and construction industries.. While many US-based architects are members of the AIA, it is not a professional requirement. History The American Institute of Architects (AIA) was founded in 1857 in New York City by a group of thirteen architects. The founding members include Charles Babcock, Henry W. Cleaveland, Henry Dudley, Leopold Eidlitz, Edward Gardiner, Richard Morris Hunt, Detlef Lienau, Fred A. Petersen, Jacob Wrey Mould, John Welch, Richard M. Upjohn, and Joseph C. Wells, with Richard Upjohn serving as the first president. They held their inaugural meeting on February 23, 1857, and invited 16 additional architects to join, including Alexander Jackson Davis, Thomas U. Walter, Frederick Clarke Withers, and Calvert Vaux. There were no architectural schools or licensing laws in the United States at the time, allowing anyone to claim to be an architect. By March 10, 1857, they had drafted a constitution and bylaws under the name New York Society of Architects. The name was later changed to The American Institute of Architects at the suggestion of Thomas U. Walter. On April 15, 1857, the members signed the new constitution, having previously filed a certificate of incorporation two days earlier. The following year, the constitution was amended to include the mission of promoting the artistic, scientific, and practical aspects of architecture, facilitating professional interaction and camaraderie, raising the profession's standing, and uniting architects for the advancement of the field. In the 1860s, architects from other cities began joining AIA. By the 1880s, chapters had been established in Albany, Baltimore, Boston, Chicago, Cincinnati, Indianapolis, Philadelphia, Rhode Island, San Francisco, St. Louis, and Washington, D.C. As of 2008, AIA boasts over 200 chapters. In 1898, the AIA moved into its new national headquarters in the historic Octagon House, in Washington, D.C. AIA rented the building for 4 years, and then purchased it in 1902. Under president of the AIA, D.

The Americans with Disabilities Act of 1990 (ADA) (42 U.S.C. § 12101) is a civil rights law that prohibits discrimination based on disability. It affords similar protections against discrimination to Americans with disabilities as the Civil Rights Act of 1964, which made discrimination based on race, religion, sex, national origin, and other characteristics illegal, and later sexual orientation and gender identity. In addition, unlike the Civil Rights Act, the ADA also requires covered employers to provide reasonable accommodations to employees with disabilities, and imposes accessibility requirements on public accommodations. In 1986, the National Council on Disability had recommended the enactment of an Americans with Disabilities Act and drafted the first version of the bill which was introduced in the House and Senate in 1988. A broad bipartisan coalition of legislators supported the ADA, while the bill was opposed by business interests (who argued the bill imposed costs on business) and conservative evangelicals (who opposed protection for individuals with HIV). The final version of the bill was signed into law on July 26, 1990, by President George H. W. Bush. It was later amended in 2008 and signed by President George W.

Sustainable architecture is a branch of architecture that focuses on the design and construction of buildings according to environmental sustainability criteria, with the aim of minimizing their negative environmental impact by enhancing efficiency, reducing material and energy consumption, and minimizing the disturbance to the surrounding ecosystem. Sometimes, sustainable architecture may also focus on the social aspect of sustainability. Social sustainability concerns sustainable handling the everyday positive and negatives of running a business. This includes the impacts that the negatives and positives have on each individual. architecture relies on social sustainability to guide the topic towards its true goal. Sustainable architecture uses a conscious approach to energy and ecological conservation in the design of the built environment.

Background Shift from narrow to broader approach The term "sustainability" in relation to architecture has so far been mostly considered through the lens of building technology and its transformations. Going beyond the technical sphere of "green design", invention and expertise, some scholars are starting to position architecture within a much broader cultural framework of the human interrelationship with nature.

actures computer memory and computer data storage products, including dynamic random-access memory (DRAM), flash memory, High Bandwidth Memory (HBM), and solid-state drives (SSDs). Founded in 1978 in Boise, Idaho, Micron is the only major American computer memory manufacturer. It is one of the "Big Three" computer memory manufacturers, along with the South Korean companies Samsung Electronics and SK Hynix. Micron marketed its consumer products under the brand Crucial, with the sub-brand Ballistix being used to denote products targeting gaming computers, until its disestablishment on 2026. Micron and Intel together created IM Flash Technologies, which produced NAND flash memory. It owned Lexar between 2006 and 2017. Sanjay Mehrotra has served as president and CEO of Micron since 2017. On May 26, 2026, Micron became the latest U.S.

n since 2017. On May 26, 2026, Micron became the latest U.S. company to reach a US$1 trillion market capitalization, amid surging demand for its HBM chips. History 1978–1999 Micron was founded in Boise, Idaho, in 1978 by Ward Parkinson, Joe Parkinson, Dennis Wilson, and Doug Pitman as a semiconductor design consulting company. Startup funding was provided by local Idaho businessmen Tom Nicholson, Allen Noble, Rudolph Nelson, and Ron Yanke. Later it received funding from Idaho billionaire J. R. Simplot, whose fortune was made in the potato business. In 1981, the company moved from consulting to manufacturing with the completion of its first wafer fabrication unit ("Fab 1"), producing 64K DRAM chips. In 1984, the company had its initial public offering. Micron sought to enter the market for RISC processors in 1991 with a product known as FRISC, targeting embedded control and signal processing applications. Running at 80 MHz and described as "a 64-bit processor with fast context-switching time and high floating-point performance", the design supported various features for timely interrupt handling and featured an arithmetic unit capable of handling both integer and floating-point calculations with a claimed throughput of 80 MFLOPS for double-precision arithmetic. Micron aimed to provide a "board-level demonstration supercomputer" in configurations with 256 MB or 1 GB of RAM. Having set up a subsidiary and with the product being designed into graphics cards and accelerators, Micron concluded in 1992 that the effort would not deliver the "best bang for the buck", reassigning engineers to other projects and discontinuing the endeavour. In 1994, founder Joe Parkinson retired as CEO and Steve Appleton took over as Chairman, President, and CEO. A 1996 3-way merger among ZEOS International, Micron Computer, and Micron Custom Manufacturing Services (MCMS) increased the size and scope of the company; this was followed rapidly with the 1997 acquisition of NetFrame Systems, in a bid to enter the mid-range server industry.

Since 2000 In 2000, Gurtej Singh Sandhu and Trung T. Doan at Micron initiated the development of atomic layer deposition high-k films for DRAM memory devices. This helped drive cost-effective implementation of semiconductor memory, starting with 90 nm node DRAM. Pitch double-patterning was also pioneered by Gurtej Singh Sandhu at Micron during the 2000s, leading to the development of 30-nm class NAND flash memory, and it has since been widely adopted by NAND flash and RAM manufacturers worldwide. In 2002, Micron spun off its personal computer business as MPC Corporation and put it up for sale. The company found the business difficult as the number 12 American computer maker with only 1.3 percent of the market. Micron and Intel created a joint venture in 2005, based in IM Flash Technologies in Lehi, Utah. The two companies formed another joint venture in 2011, IM Flash Singapore, in Singapore. In 2012 Micron became sole owner of this second joint venture. In 2006 Micron acquired Lexar, an American manufacturer of digital media products. The company changed leadership again in June 2007 with COO Mark Durcan becoming president. In 2008, Micron converted the Avezzano chip fab, formerly a Texas Instruments DRAM fab, into a production facility for CMOS image sensors sold by Aptina Imaging. In 2008, Micron spun off Aptina Imaging, which was acquired by ON Semiconductor in 2014. Micron retained a stake in the spinoff. However, the core company suffered setbacks and had to layoff 15 percent of its workforce in October 2008, during which period the company also announced the purchase of Qimonda's 35.6 percent stake in Inotera Memories for $400 million. The trend of layoffs and acquisitions continued in 2009 with the termination of an additional 2,000 employees, and the acquisition of the FLCOS microdisplay company Displaytech. Micron agreed to buy flash-chip maker Numonyx for $1.27 billion in stock in February 2010. On February 3, 2012, CEO Appleton died in a plane crash shortly after takeoff from the Boise Airport. He was the pilot and sole occupant of the Lancair IV aircraft. Mark Durcan replaced Appleton as the CEO shortly thereafter, eliminating his former title of president. In 2013, the Avezzano chip fab was sold to LFoundry. In the 2012 to 2014 period, Micron again went through an acquisition-layoff cycle, becoming the majority shareholder of Inotera Memories, purchasing Elpida Memory for $2 billion and the remaining shares in Rexchip, a PC memory chip manufacturing venture between Powerchip and Elpida Memory for $334 million, while announcing plans to lay off approximately 3,000 workers. Through the Elpida acquisition, Micron became a major supplier to Apple Inc. for the iPhone and iPad. In December 2016 Micron finished acquiring the remaining 67 percent of Inotera, making it a 100 percent subsidiary of Micron. In April 2017, Micron announced Sanjay Mehrotra as the new president and CEO to replace Mark Durcan. In June 2017 Micron announced it was discontinuing the Lexar retail removable media storage business and putting some or all of it up for sale. In August of that year the Lexar brand was acquired by Longsys, a flash memory company based in Shenzhen, China. In May 2018, Micron Technology and Intel launched QLC NAND memory to increase storage density. The company ranked 150th on the Fortune 500 list of largest United States corporations by revenue. In February 2019, the first microSD card with a storage capacity of 1 terabyte (TB) was announced by Micron. As of March 2020 3.84TB Micron 5210 Ion is the cheapest large-capacity SSD in the world. In September 2020 the company introduced the world's fastest discrete graphics memory solution. Working with computing technology leader Nvidia, Micron debuted GDDR6X in the Nvidia GeForce RTX 3090 and GeForce RTX 3080 graphics processing units (GPUs). In November 2020, the company unveiled a new 176-layer 3D NAND module. It offers improved read and write latency and is slated to be used in the production of a new generation of solid-state drives. On October 22, 2021, Micron closed the sale of IM Flash's Lehi, Utah fab to Texas Instruments for a sale price of US$900 million. In February 2022, Micron announced that it would discontinue its Ballistix gaming brand. With the passage of the CHIPS and Science Act, Micron announced its pledge to invest billions in new manufacturing within the United States. In September 2022, Micron announced it would invest $15 billion in a new facility in Boise, Idaho. In October 2022, Micron announced a $100 billion expansion in Clay, New York. Micron Technology owed Netlist, Inc. $445 million in damages for infringing Netlist's patents related to memory-module technology for high-performance computing. The jury found that Micron's semiconductor-memory products violated two of Netlist's patents willfully, potentially allowing the judge to triple the damages. Netlist had sued Micron in 2022, accusing three of its memory-module lines of patent infringement, which Micron denied, also arguing the patents' invalidity. The U.S.

city in Idaho. As of the 2020 census, Caldwell had a population of 59,996. Caldwell is considered part of the Boise metropolitan area, and is the location of the College of Idaho. The city is located approximately 24 miles (39 km) west of Boise, and approximately 17 miles (27 km) east of the Oregon border. History The present-day location of Caldwell is along a natural passageway to the Inland and Pacific Northwest. Native American tribes from the west coast, north Idaho and as far away as Colorado came to the banks of the Boise River for annual trading fairs, or rendezvous. European and some Hawaiian explorers and traders soon followed the paths left by Native Americans and hopeful emigrants later forged the Oregon Trail and followed those paths to seek a better life in the Oregon Territory. Pioneers of the Trail traveled along the Boise River to Canyon Hill and forded the river close to the Silver Bridge on Plymouth Street. During the Civil War, the discovery of gold in Idaho's mountains brought a variety of new settlers into the area. Many never made it to the mines but settled along the Boise River and run ferries, stage stations, and freighting businesses. These early entrepreneurs created small ranches and farms in the river valleys. Caldwell's inception occurred largely as a result of the construction of the Oregon Short Line Railroad, which connected Wyoming to Oregon through Idaho. Robert E. Strahorn came to the Boise River Valley in 1883 to select a route for the railroad. He rejected the grade into Boise City as too steep and chose a site 30 miles to the west. He drove a stake into an alkali flat of sagebrush and greasewood and the City of Caldwell was platted. Caldwell was named after one of Strahorn's business partners, Alexander Caldwell, a former senator from Kansas. When Caldwell was platted in August 1883, its founder, the Idaho and Oregon Land Improvement Company, started persuading settlers and businessmen to move to the area. Within four months, Caldwell had 600 residents living in 150 dwellings, 40 businesses, a school, a telephone exchange, and two newspapers. On January 15, 1890, the Board of Commissioners of Ada County issued a handwritten order incorporating the City of Caldwell. The College of Idaho was founded in Caldwell in 1891. In 1892, Canyon County was established from a portion of Ada County, and Caldwell was named the county seat. Irrigation canals and waterways were constructed throughout Canyon County, providing the foundation for an agricultural economy. The Oregon Short Line Railroad became part of the larger Union Pacific Railroad network and in 1906 the Caldwell freight and passenger depot was constructed. Caldwell experienced moderate growth as an agricultural processing, commercial retail and educational center during the 20th century. In 2009, the City of Caldwell completed a revitalization project to restore Indian Creek, which runs through downtown Caldwell, but had been used for sewage disposal by local industries and been covered over.

location of the College of Idaho. The city is located approximately 24 miles (39 km) west of Boise, and approximately 17 miles (27 km) east of the Oregon border. History The present-day location of Caldwell is along a natural passageway to the Inland and Pacific Northwest. Native American tribes from the west coast, north Idaho and as far away as Colorado came to the banks of the Boise River for annual trading fairs, or rendezvous. European and some Hawaiian explorers and traders soon followed the paths left by Native Americans and hopeful emigrants later forged the Oregon Trail and followed those paths to seek a better life in the Oregon Territory. Pioneers of the Trail traveled along the Boise River to Canyon Hill and forded the river close to the Silver Bridge on Plymouth Street. During the Civil War, the discovery of gold in Idaho's mountains brought a variety of new settlers into the area. Many never made it to the mines but settled along the Boise River and run ferries, stage stations, and freighting businesses. These early entrepreneurs created small ranches and farms in the river valleys. Caldwell's inception occurred largely as a result of the construction of the Oregon Short Line Railroad, which connected Wyoming to Oregon through Idaho. Robert E. Strahorn came to the Boise River Valley in 1883 to select a route for the railroad. He rejected the grade into Boise City as too steep and chose a site 30 miles to the west. He drove a stake into an alkali flat of sagebrush and greasewood and the City of Caldwell was platted. Caldwell was named after one of Strahorn's business partners, Alexander Caldwell, a former senator from Kansas. When Caldwell was platted in August 1883, its founder, the Idaho and Oregon Land Improvement Company, started persuading settlers and businessmen to move to the area. Within four months, Caldwell had 600 residents living in 150 dwellings, 40 businesses, a school, a telephone exchange, and two newspapers. On January 15, 1890, the Board of Commissioners of Ada County issued a handwritten order incorporating the City of Caldwell. The College of Idaho was founded in Caldwell in 1891. In 1892, Canyon County was established from a portion of Ada County, and Caldwell was named the county seat. Irrigation canals and waterways were constructed throughout Canyon County, providing the foundation for an agricultural economy. The Oregon Short Line Railroad became part of the larger Union Pacific Railroad network and in 1906 the Caldwell freight and passenger depot was constructed. Caldwell experienced moderate growth as an agricultural processing, commercial retail and educational center during the 20th century. In 2009, the City of Caldwell completed a revitalization project to restore Indian Creek, which runs through downtown Caldwell, but had been used for sewage disposal by local industries and been covered over.

Eagle is a city in Ada County, Idaho, ten miles (16 km) northwest of downtown Boise. The population was 30,346 at the 2020 census. History 19th century Eagle Island in Idaho was settled in 1863 by Truman Coe Catlin, who later shifted from crop farming to dairy farming, starting the island's dairy tradition. He also pioneered irrigation in the area by constructing a wide irrigation ditch. The most notable early community developer was Thomas Hugh Aiken, a Canadian surveyor, who helped establish the Eagle community in the 1870s.

Parks and recreation The city features numerous parks, including Arboretum Park, Friendship Park, Heritage Park, Orval Krasen Park, Reid W. Merrill Sr. Community Park, and Stephen C. Guerber Park, among others. The Parks and Recreation department offers youth sports leagues, camps, special events (such as Eagle Fun Days), and maintains extensive trails. Nearby Eagle Island State Park provides a swimming beach, trails, disc golf, and winter sports. Education Most of Eagle is in the West Ada School District, with a small portion in the Boise School District.

20th century The Eagle Fish Hatchery, established in the late 1940s in Idaho, was originally part of a trout program until the 1980s. In 1991, it was restructured to support the conservation of Snake River sockeye salmon, an endangered species listed that year. The hatchery's mission shifted to preserving the species and its genetic diversity through the development of eight broodstocks derived from smolts, anadromous adults, and residual populations.

In the United States, an architectural firm or architecture firm is a business that employs one or more licensed architects and practices the profession of architecture; while in South Africa, the United Kingdom, Ireland, Denmark and other countries, an architectural firm is a company or partnership that offers architectural services.

es, an architectural firm is a company or partnership that offers architectural services. History Architects (or master builders) have existed since early in recorded history. The earliest recorded architects include Imhotep (c. 2600 BCE) and Senemut (c. 1470 BCE). No writings exist to describe how these architects performed their work. However, members of the nobility had staffs of assistants and retainers to help refine and implement their work. The oldest surviving book on architecture, De architectura by the Roman architect Vitruvius describes the design and construction of towns, buildings, clocks, and machines, but provides no information about the organisation of the architect's assistants. It is generally accepted that throughout most of human history, most architects were wealthy individuals who derived their primary income from activities other than design and who practiced design as a part-time pursuit, employing assistants on a project-by-project basis. It was only in the 19th century that architecture began to be practiced as a full-time profession, when specific training and accreditation began to be offered. In the United States, Charles Bulfinch is the first American believed to have worked as a full-time professional architect. Henry Hobson Richardson may have been one of the first to have an established office and McKim, Mead, and White may have been among the first to resemble the large, modern architectural firm. The oldest active architecture firms in the United States are SmithGroup of Detroit, MI and Luckett and Farley of Louisville, KY, having both been founded in 1853. In the United Kingdom, Brierley Groom is the oldest continuing practice, having been founded in 1750 at York, England.

Licensure and legal form Architects may be licensed by individual states or provinces, as they are in Australia, Canada and the United States. Licensure is usually achieved by a combination of formal education, internship, and examinations. Although architects are licensed individually, state laws allow them to join together in various forms of business organisation. All states in the United States allow architects to form partnerships, most allow architects to form corporations or professional corporations, and some allow limited liability partnerships (LLPs) or limited liability companies (LLCs). Some states require the firm to obtain a registration to provide architectural services. Others merely require that the architectural work of the firm be performed under the direct supervision of an architect licensed in the state. A few US states allow corporations to provide architectural services provided that a licensed employee of the firm serves as architect of record for any project. In the United Kingdom and other countries, an architecture firm must have a business registration. The firm needs at least one registered professional within the team to offer a full architectural service.
