Green building in the United States is the practice of designing, constructing, operating, and certifying buildings in the United States to reduce environmental impact, increase energy efficiency, and improve occupant health. The movement intersects with federal agencies, nonprofit organizations, professional associations, and private industry to drive standards, technologies, policies, and market adoption across states and metropolitan regions. Influences include early conservation efforts, postwar architectural trends, and contemporary sustainability advocacy from civic institutions.

History and development

The modern era traces roots to advocates such as Rachel Carson, whose work influenced environmental awareness, and initiatives like the National Environmental Policy Act and Clean Air Act that shaped building-related regulation. Early sustainable design principles were advanced by architects linked to the American Institute of Architects and practitioners influenced by precedents including Frank Lloyd Wright and the Usonian house movement. The energy crises of the 1970s catalyzed programs at the Department of Energy and research at laboratories including Lawrence Berkeley National Laboratory and Oak Ridge National Laboratory, while demonstration projects at Arlington County and the Rockefeller Foundation–funded efforts showcased passive solar design. In the 1990s and 2000s, organizations such as the U.S. Green Building Council, World Green Building Council, and International Living Future Institute institutionalized certification, while state efforts in California, New York, and Massachusetts accelerated adoption. Major events like the Energy Policy Act of 2005 and the American Recovery and Reinvestment Act of 2009 funded efficiency retrofits and influenced standards. Academic centers at Massachusetts Institute of Technology, Harvard University, and Stanford University expanded research on materials, embodied carbon, and resilience.

Standards and certification systems

Certification systems include the Leadership in Energy and Environmental Design program from the U.S. Green Building Council, the Energy Star program administered by the Environmental Protection Agency, the WELL Building Standard from the International WELL Building Institute, and the Living Building Challenge by the International Living Future Institute. State and local codes increasingly reference standards such as the International Energy Conservation Code promulgated by the International Code Council and the ASHRAE Standard 90.1 developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers. Federal procurement follows guidance from the General Services Administration and policies from the Office of Management and Budget. Green mortgage and financing mechanisms involve institutions like the Federal Housing Administration and private actors such as Fannie Mae and Freddie Mac. Rating systems for historic buildings intersect with the National Trust for Historic Preservation and the Secretary of the Interior's Standards for Rehabilitation.

Green building technologies and practices

Common technologies include high-performance glazing and façades developed by firms collaborating with research centers like the National Renewable Energy Laboratory, photovoltaic systems by manufacturers linked to First Solar and SunPower, and HVAC innovations guided by Carrier Global Corporation and Trane Technologies. Water efficiency uses fixtures conforming to American Water Works Association recommendations and rainwater harvesting designs employed in projects associated with the U.S. Environmental Protection Agency. Materials strategies involve recycled-content products from companies like Steelcase, low-VOC paints influenced by standards from the California Air Resources Board, and mass timber engineered by firms such as Weyerhaeuser and projects supported by the American Wood Council. Smart building controls draw on platforms from Siemens and Schneider Electric, while resilience practices incorporate floodplain mapping from the Federal Emergency Management Agency and resilience planning promoted by the Rockefeller Foundation's 100 Resilient Cities initiative.

Policy, incentives, and regulation

Federal policy includes tax incentives under the Energy Policy Act of 1992 and subsequent extensions, grants administered by the Department of Energy and Environmental Protection Agency, and executive actions from the White House. State programs such as California Title 24, New York State Energy Research and Development Authority, and Massachusetts Stretch Code set benchmarks and incentives. Municipal green building ordinances in cities like Seattle, Austin, Chicago, and Boston establish local requirements and density bonuses. Utilities including Pacific Gas and Electric Company and Consolidated Edison offer rebates and performance-based incentives. Financial mechanisms involve tax credits, Property Assessed Clean Energy programs pioneered in jurisdictions like Berkeley, and public–private partnerships with organizations such as the Federal Financing Bank.

Market trends and economic impacts

Market adoption is tracked by consultancies and associations such as McKinsey & Company, Deloitte, U.S. Green Building Council, and Green Building Initiative. Commercial real estate firms including CBRE Group and Jones Lang LaSalle report premium rents and occupancy for green-certified assets in metropolitan markets like New York City, San Francisco, Los Angeles, and Washington, D.C.. Residential green retrofits are influenced by mortgage investors Fannie Mae and Freddie Mac policies and programs by nonprofits such as Habitat for Humanity. Supply chains and manufacturing are affected by trade policy debates involving U.S. Department of Commerce and international partners like Canada and China. Studies by Brookings Institution and Urban Land Institute analyze job creation in energy-efficiency sectors and lifecycle cost savings for owners.

Environmental and social outcomes

Research from institutions like National Oceanic and Atmospheric Administration, Intergovernmental Panel on Climate Change, and National Academies of Sciences, Engineering, and Medicine evaluates greenhouse gas reductions, urban heat island mitigation, and public health outcomes. Green buildings can complement climate adaptation strategies outlined by Federal Emergency Management Agency and National Climate Assessment reports. Social equity initiatives promoted by groups such as the Enterprise Community Partners and Local Initiatives Support Corporation seek to ensure affordable housing benefits from efficiency investments, while labor standards are advanced by unions like the Building Trades Unions. Health-focused outcomes are studied by Harvard T.H. Chan School of Public Health and the Centers for Disease Control and Prevention.

Major projects and regional initiatives

Notable projects include the Bullitt Center in Seattle, the California Academy of Sciences in San Francisco, the Sustainability Base at NASA Ames Research Center, and the Salt Lake City Public Safety Building. Regional initiatives include the New York City Climate Mobilization Act, LEED for Cities pilots in Los Angeles, Greenest City Action Plan in Vancouver-adjacent collaborations, and the Cool Roofs programs in Miami and Las Vegas. University-led models include sustainability campuses at University of California, Berkeley, Arizona State University, and University of Michigan. Philanthropic and nonprofit partnerships involve the Rockefeller Foundation, Kresge Foundation, and The Nature Conservancy.
