  2. Low-energy house - Wikipedia

    en.wikipedia.org/wiki/Low-energy_house

    A low-energy house is characterized by an energy-efficient design and technical features which enable it to provide high living standards and comfort with low energy consumption and carbon emissions. Traditional heating and active cooling systems are absent, or their use is secondary.

  3. 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 ...

  4. Energy efficiency in British housing - Wikipedia

    en.wikipedia.org/wiki/Energy_efficiency_in...

    In 2003 the housing stock in the United Kingdom was amongst the least energy efficient in Europe. [8] In 2004, housing (including space heating, hot water, lighting, cooking, and appliances) accounted for 30.23% of all energy use in the UK (up from 27.70% in 1990). [9] The figure for London is higher at approximately 37%. [10]

  5. Passive house - Wikipedia

    en.wikipedia.org/wiki/Passive_house

    In the United States, a house built to passive house standard results in a building that requires space heating energy of 1 British thermal unit per square foot (11 kJ/m 2) per heating degree day, compared with about 5 to 15 BTU/sq ft (57 to 170 kJ/m 2) per heating degree day for a similar building built to meet the 2003 Model Energy Efficiency ...

  6. Energy performance certificate - Wikipedia

    en.wikipedia.org/wiki/Energy_performance_certificate

    Energy performance certificates (EPCs) are a rating scheme to summarise the energy efficiency of buildings. [4] [5] The building is given a rating between A (Very efficient) - G (Inefficient). The EPC will also include tips about the most cost-effective ways to improve the home energy rating. Energy performance certificates are used in many ...

  7. Thermal insulation - Wikipedia

    en.wikipedia.org/wiki/Thermal_insulation

    Thermal insulation is integral to greenhouse design, enabling controlled environments for plant growth and energy efficiency. Common insulation techniques include the use of double-layer films and multi-wall polycarbonate panels, which trap air between layers to reduce heat transfer while maintaining sufficient light transmission for ...

  8. 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 ...

  9. European Union energy label - Wikipedia

    en.wikipedia.org/wiki/European_Union_energy_label

    A new energy label, introduced in 2010, is based on the energy efficiency index (EEI), and has energy classes in the range A+++ to D. [11] The EEI is a measure of the annual electricity consumption, and includes energy consumed during power-off and standby modes, and the energy consumed in 220 washing cycles. For the washing cycles, a weighted ...
