United States building energy codes are a subset of building codes that set minimum requirements for energy-efficient design and construction for new and renovated buildings. [2] The intent of these energy codes is to moderate and reduce energy use and emissions throughout the lifetime of a building. [ 2 ]
The International Energy Conservation Code (IECC) is a building code created by the International Code Council in 2000. It is a model code adopted by many states and municipal governments in the United States for the establishment of minimum design and construction requirements for energy efficiency.
These statutes direct DOE to participate in industry processes to develop model building energy codes, issue determinations as to whether updated codes result in energy savings, and provide technical assistance to states to implement and comply with the codes. The BECP is part of DOE's Energy Efficiency and Renewable Energy Building ...
Homes built under this code are about 53% more energy efficient than those built to comply with the 2016 Energy Code. [6] This code provides a market for "smart" technologies. [7] The 2019 Code added photovoltaic system requirements for low-rise residential buildings. Exceptions grant a reduction in size for photovoltaic systems.
With each new edition of ANSI/ASHRAE/IES Standard 90.1, DOE is required by statute [8] to issue a determination as to whether the updated edition will improve energy efficiency in commercial buildings. DOE issued a positive determination stating that Standard 90.1-2013 would achieve greater energy efficiency in buildings subject to that code ...
The IgCC addressed some aspects of this issue in its 2015 version by introducing a compliance pathway based on the energy use of the building over a three-year period, where a building will be required to meet baseline requirements outlined in the International Energy Conservation Code (IECC).
The Building Codes Assistance Project (BCAP) is a non-profit organization that advocates for the adoption, implementation, and advancement of building energy codes. It was established in 1994 as a joint initiative of the Alliance to Save Energy (ASE), the American Council for an Energy-Efficient Economy (ACEEE), and the Natural Resources Defense Council (NRDC).

Building-related energy efficiency innovation takes many forms, including improvements in water heaters; refrigerators and freezers; building control technologies for heating, ventilation, and cooling (HVAC); adaptive windows; building codes; and lighting. [109] Energy-efficient technologies can enable superior performance.
