Green building

Green building
Name	Green building

Green building is an approach to design, construction, and operation of structures that seeks to reduce environmental impact, enhance occupant health, and improve resource efficiency. It involves integrated strategies spanning site selection, energy systems, materials, water management, and indoor environments, informed by standards, certifications, and policy incentives. Practitioners draw on interdisciplinary research and implementation experience from architecture, engineering, urban planning, and environmental science.

Definition and Principles

Green building emphasizes sustainability principles such as energy efficiency, water conservation, waste reduction, and occupant well‑being, referencing frameworks from United Nations Environment Programme, World Green Building Council, International Energy Agency, Intergovernmental Panel on Climate Change, and United Nations Framework Convention on Climate Change. Key concepts include lifecycle assessment, embodied carbon accounting, passive design, and resilience as articulated by National Renewable Energy Laboratory, Lawrence Berkeley National Laboratory, European Commission, U.S. Green Building Council, and World Resources Institute. Practitioners integrate principles from Leadership in Energy and Environmental Design, Building Research Establishment Environmental Assessment Method, Passive House Institute, Green Star, and WELL Building Standard with guidance from institutions such as Harvard University Graduate School of Design, Massachusetts Institute of Technology, ETH Zurich, Delft University of Technology, and University of Cambridge.

History and Development

The modern green building movement arose in response to energy crises, environmental activism, and advances in building science during the 20th century, with antecedents in work by Frank Lloyd Wright, Le Corbusier, Ken Yeang, Buckminster Fuller, and Jane Jacobs. Milestones include energy conservation measures after the 1973 oil crisis, early passive solar experiments at Solar Energy Research Institute (now National Renewable Energy Laboratory), and the emergence of rating systems such as LEED and BREEAM in the late 20th century. Policy drivers include emissions commitments under Kyoto Protocol, Paris Agreement, and national initiatives from European Union, United States Department of Energy, China National Energy Administration, Japan Ministry of the Environment, and Australia Department of Industry, Science and Resources.

Design and Construction Practices

Design and construction practices combine architectural strategies and engineering systems developed at firms and institutions like Foster + Partners, Skidmore, Owings & Merrill, Zaha Hadid Architects, Arup Group, and Atkins. Techniques include passive solar design from practitioners influenced by Richard Neutra and Alvar Aalto, natural ventilation approaches taught at Columbia University Graduate School of Architecture, integration of daylighting studies using tools from Autodesk and IES VE, and performance simulation pioneered at Lawrence Berkeley National Laboratory. Construction methods draw on modular construction trends seen in Katerra, prefabrication systems used by Sekisui House, and adaptive reuse projects like Tate Modern and High Line driven by developers such as Related Companies and planners from New York City Department of City Planning.

Materials and Technologies

Materials and technologies include low‑embodied carbon materials evaluated using standards from ISO, ASTM International, European Committee for Standardization, and lifecycle databases maintained by Inventory of Carbon & Energy, Greenhouse Gas Protocol, and World Resources Institute. Innovations include cross‑laminated timber promoted by Stora Enso, high‑performance glazing developed by Pilkington, advanced insulation from Owens Corning, and HVAC advancements from Carrier Global Corporation and Trane Technologies. Renewable energy integration uses photovoltaic modules from companies like First Solar and SunPower, battery systems by Tesla, Inc. and LG Chem, and district energy concepts applied in projects by Denmark Energy Agency and Fortum. Water technologies include greywater recycling systems by Wabag and rainwater harvesting installations championed in projects supported by World Bank programs.

Certification and Standards

Certification frameworks and standards guide evaluation and marketization, with prominent systems including LEED (administered by U.S. Green Building Council), BREEAM (from Building Research Establishment), and Passive House (run by Passive House Institute). Other systems and standards include WELL Building Standard (by International WELL Building Institute), Green Star (from Green Building Council of Australia), DGNB System (by German Sustainable Building Council), CASBEE (from Japan Sustainable Building Consortium), and national codes such as the International Building Code influences and ASHRAE standards (notably ASHRAE 90.1). Regional certification schemes are implemented by organizations like China Green Building Council, India Green Building Council, Green Building Council South Africa, and Green Building Council of Indonesia.

Environmental and Economic Impacts

Studies by Intergovernmental Panel on Climate Change, International Energy Agency, World Bank, McKinsey Global Institute, and Rocky Mountain Institute quantify benefits including reduced greenhouse gas emissions, lower operational costs, improved air quality, and enhanced productivity. Economic analyses from Harvard Business School, University of California, Berkeley, and London School of Economics compare lifecycle costs and payback periods, while case studies from projects such as The Edge (Amsterdam), One Central Park, and Bullitt Center demonstrate energy performance and financial models. Environmental impacts—assessed using methodologies from ISO 14040 and Greenhouse Gas Protocol—include reductions in operational energy and embodied carbon, with mitigation strategies promoted by C40 Cities and ICLEI.

Policy, Incentives, and Adoption Worldwide

Adoption is shaped by policy instruments and incentives from bodies such as European Commission, United States Environmental Protection Agency, China National Development and Reform Commission, Indian Ministry of Housing and Urban Affairs, and municipal programs in Singapore. Mechanisms include building codes, tax incentives, feed‑in tariffs, green bonds issued by entities like World Bank and European Investment Bank, and public procurement standards set by agencies such as UNEP Finance Initiative and G20. International networks and campaigns—organized by World Green Building Council, C40 Cities, ICLEI, Global Covenant of Mayors for Climate & Energy, and United Nations Environment Programme Finance Initiative—accelerate diffusion through pilots, capacity building, and finance mechanisms deployed by multilateral development banks like Asian Development Bank and Inter-American Development Bank.
