2. European Union energy label - Wikipedia

   en.wikipedia.org/wiki/European_Union_energy_label

   EU Directive 92/75/EC (1992) [1] established an energy consumption labelling scheme. The directive was implemented by several other directives [2] thus most white goods, light bulb packaging and cars must have an EU Energy Label clearly displayed when offered for sale or rent. The energy efficiency of the appliance is rated in terms of a set of ...

3. Efficient energy use - Wikipedia

   en.wikipedia.org/wiki/Efficient_energy_use

   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. For example, insulating a building allows it to use less heating and cooling energy while still ...

   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 ...

6. Seasonal energy efficiency ratio - Wikipedia

   en.wikipedia.org/wiki/Seasonal_energy_efficiency...

   The energy efficiency ratio (EER) of a particular cooling device is the ratio of output cooling energy (in BTUs) to input electrical energy (in watt-hours) at a given operating point. EER is generally calculated using a 95 °F (35 °C) outside temperature and an inside (actually return-air) temperature of 80 °F (27 °C) and 50% relative humidity.

7. EnerGuide - Wikipedia

   en.wikipedia.org/wiki/EnerGuide

   EnerGuide is the official mark of the Government of Canada for its energy performance rating and labeling program for key consumer items—houses, light-duty vehicles, and certain energy-using products. [1] The EnerGuide efficiency percent is calculated by dividing the power output by power input. EnerGuide labelling exists for appliances ...
