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.
In the United Kingdom, a Seasonal Energy Efficiency ratio (SEER) for refrigeration and air conditioning products, similar to the ESEER but with different load profile weighting factors, is used for part of the Building Regulations Part L calculations within the Simplified Building Energy Model (SBEM) software, and are used in the production of Energy Performance Certificates (EPC) for new ...
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 averages instead of a constant 35 °C (95 °F) outdoor temperature.
HERS—Home energy rating standard (conservation) HHI—Herfindahl–Hirschman Index (markets) HID—high intensity discharge (electricity) hp—Horsepower (measurement) HRSG—Heat recovery steam generation; HTGR—high temperature gas cooled reactor (nuclear) HVAC—Heating, ventilation, and air conditioning (conservation)
The efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER), which is defined by the Air Conditioning, Heating and Refrigeration Institute in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment. [61]
The rating level of buildings is determined in three parameters; Basic Items: refers to the regulated energy use per square meter, obtained by computer modeling or measurements. Required Items: refers to minimum performance requirements for building envelope and Heating Ventilation and Air-Conditioning (HVAC).
