In the United States, 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, a trade association, in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment.

Heating seasonal performance factor (HSPF) is a term used in the heating and cooling industry. HSPF is specifically used to measure the efficiency of air source heat pumps . HSPF is defined as the ratio of heat output (measured in BTUs) over the heating season to electricity used (measured in watt-hours ).
In Europe, the seasonal efficiency of refrigeration equipment, chillers and air conditioners is often rated by the European seasonal energy efficiency ratio (ESEER) which is controlled (among others) by the Eurovent Certification Company. [1] A similar standard in the United States is the integrated energy efficiency ratio (IEER).
A new energy label, introduced in 2010, is based on the energy efficiency index (EEI), and has energy classes in the range A+++ to D. [11] The EEI is a measure of the annual electricity consumption, and includes energy consumed during power-off and standby modes, and the energy consumed in 220 washing cycles.
Traditional brick-and-mortar banks tend to offer low interest rates of 0.01% to 0.10% APY, if they pay out interest at all. Online banks offer higher rates, passing along overhead savings in the ...
Key takeaways. Using savings to fund renovations avoids the extra expense of interest and accumulation of debt, and encourages sticking to a budget. But it depletes cash reserves and may mean ...
e. A heat pump is a device that consumes work (or electricity) to transfer heat from a cold heat sink to a hot heat sink. Specifically, the heat pump transfers thermal energy using a refrigeration cycle, cooling the cool space and warming the warm space. [ 1] In cold weather, a heat pump can move heat from the cool outdoors to warm a house (e.g ...
