   They then input the observations into a software program which performs the calculation of energy efficiency. The program gives a single number for the rating of energy efficiency, and a recommended value of the potential for improvement. There are similar figures for environmental impact. A table of estimated annual energy bills (and the ...

3. 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]

4. 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.

5. 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 ...

6. Heating, ventilation, and air conditioning - Wikipedia

   en.wikipedia.org/wiki/Heating,_ventilation,_and...

   EER is the Energy Efficiency Ratio based on a 35 °C (95 °F) outdoor temperature. To more accurately describe the performance of air conditioning equipment over a typical cooling season a modified version of the EER, the Seasonal Energy Efficiency Ratio (SEER), or in Europe the ESEER, is used. SEER ratings are based on seasonal temperature ...

7. Audit - Wikipedia

   en.wikipedia.org/wiki/Audit

   An energy audit is an inspection, survey and analysis of energy flows for energy conservation in a building, process or system to reduce the amount of energy input into the system without negatively affecting the output(s).

8. 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 ...
