The SEER rating of a unit is the cooling output during a typical cooling-season divided by the total electric energy input during the same period. The higher the unit's SEER rating the more energy efficient it is. In the U.S., the SEER is the ratio of cooling in British thermal units (BTUs) to the energy consumed in watt-hours.
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.
SEER—seasonal E efficiency ratio; SHGC—solar heat gain coefficient; SIR—savings-to-investment ratio (energy conservation investments) SLA—Specific leakage area; SPB—Simple Payback (energy conservation investments) SSE—steady-state efficiency; U-value—thermal transmittance (also called U-factor) WF—water factor (clothes washers)
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
EER may refer to: East of England Regiment, a British Army Reserve unit; Effective exchange rate; Energy efficiency rating in the Australian Capital Territory; Energy efficiency ratio, of a cooling device; Engineering education research; Enhanced entity–relationship model; Enlisted Evaluation Report, used by the United States Army
House Energy Rating, a building's thermal performance for residential homes in Australia; Home energy rating, a measurement of a home's energy efficiency, used primarily in the United States; National Home Energy Rating, an accreditation scheme for energy assessors and a rating scale for the energy efficiency of housing in the United Kingdom
Fitch forecast China's economic growth would slow to 4.5% in 2024 from 5.2% last year, in contrast to Citi and the International Monetary Fund, which both revised up their China forecasts.
