2. 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 ...

   en.wikipedia.org/wiki/Energy_Performance_of...

   This version of the EPBD (Directive 2010/31/EU) broadened its focus on Nearly Zero-energy buildings, cost optimal levels of minimum energy performance requirements as well as improved policies. According to the recast: [4] for buildings offered for sale or rent, the energy performance certificates shall be stated in the advertisements

4. Coefficient of performance - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_performance

   A realistic indication of energy efficiency over an entire year can be achieved by using seasonal COP or seasonal coefficient of performance (SCOP) for heat. Seasonal energy efficiency ratio (SEER) is mostly used for air conditioning. SCOP is a new methodology which gives a better indication of expected real-life performance of heat pump ...

   At the end of 2025, new Government rules means that any home rented out under a new contract needs to have a C rating or above. By 2028, all rentals have to be up to that level.

7. Energy hierarchy - Wikipedia

   en.wikipedia.org/wiki/Energy_hierarchy

   Energy efficiency was a lower priority when energy was cheap and awareness of its environmental impact was low. In 1975 the average fuel economy of a car in the US was under 15 miles per gallon [ 6 ] Incandescent light bulbs, which were the most common type until the late 20th century, waste 90% of their energy as heat, with only 10% converted ...
