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.
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 ...
the energy efficiency ratio in cooling mode at full load; the appliance type (cooling only, cooling/heating) the cooling mode (air- or water-cooled) the noise rating in dB (where applicable) Labels for air conditioners with heating capability also contain: the heat output at full load in kW; the heating mode energy efficiency category
A similar standard in the United States is the integrated energy efficiency ratio (IEER). The ESEER is calculated by combining full and part load operating Energy Efficiency Ratios (EER), for different seasonal air or water temperatures, and including for appropriate weighting factors. These values are shown in the following table.
The Energy Efficiency Rating (EER) is a score applied to dwellings in the Australian Capital Territory. It ranges from zero to six system– the higher the number of stars, the better. This is mandatory for all dwellings offered for sale in the ACT. The term can also refer to a rating given to household goods sold in the EU.
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 ...
The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [1] [2] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. The COP is used in thermodynamics.
The Nationwide House Energy Rating Scheme (NatHERS) is an Australian scheme to measure the energy efficiency of a residential dwelling. An accredited software tool assesses the home based on a variety of criteria and produces an energy star rating .
