  2. United States building energy codes - Wikipedia

    en.wikipedia.org/wiki/United_States_building...

    Note: Energy Consumption for combined commercial and residential sectors is 39% of Total Energy Consumption when electrical system energy losses are included. [1] 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]

  3. House Energy Rating - Wikipedia

    en.wikipedia.org/wiki/House_energy_rating

    The House Energy Rating (HER) or House Energy Rating Scheme (HERS) are worldwide standard measures of comparison by which one can evaluate the energy efficiency of a new or an existing building. The comparison is generally done for energy requirements for heating and cooling of indoor space. The energy is the main criterion considered by any ...

  4. Energy conservation - Wikipedia

    en.wikipedia.org/wiki/Energy_conservation

    Measurable energy conservation and efficiency gains in the 1980s led to the 1987 Energy Security Report to the President (DOE, 1987) that "the United States uses about 29 quads less energy in a year today than it would have if our economic growth since 1972 had been accompanied by the less- efficient trends in energy use we were following at ...

  5. Efficient energy use - Wikipedia

    en.wikipedia.org/wiki/Efficient_energy_use

    Common energy efficiency label on appliances to indicate their energy efficiency in a clear manner. Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems.

  6. Home Energy Rating - Wikipedia

    en.wikipedia.org/wiki/Home_Energy_Rating

    The Home Energy Rating is an American estimated measurement of a home's energy efficiency based on normalized modified end-use loads (nMEULs). [1] In the United States, the Residential Energy Services Network (RESNET) is responsible for creation and maintenance of the RESNET Mortgage Industry National Home Energy Rating Standards (MINHERS), a proprietary system of standards, [2] which includes ...

  7. California Energy Code - Wikipedia

    en.wikipedia.org/wiki/California_Energy_Code

    The 2019 California Energy Code became effective on January 1, 2020. [5] It focuses on such areas such as residential photovoltaic systems, thermal envelope standards and non-residential lighting requirements. Homes built under this code are about 53% more energy efficient than those built to comply with the 2016 Energy Code. [6]

  8. Energy efficiency gap - Wikipedia

    en.wikipedia.org/wiki/Energy_efficiency_gap

    Perceived risk of energy-efficiency investments. Consumers and businesses can be very risk-averse in terms of investing in energy efficiency technologies. The uncertainties of fuel prices and high discount rate for operating costs have both made energy-efficiency investments even more "risky” for many decision makers. Information gaps.

  9. EnergyGuide - Wikipedia
