The Home Energy Saver is built on DOE-2, a computer program for building heating and cooling energy analysis and design. [3] DOE-2 performs a thermal load simulation that accounts for heating and cooling equipment and thermal distribution efficiencies, infiltration, and thermostat management. [4]
Likewise, a similar home in Miami, Florida, whose heating degree days for the heating season is 500, would require around one tenth of the energy required to heat the house in New York City. [7] However, this is a theoretical approach as the level of insulation of a building affects the demand for heating. For example, temperatures often drop ...
Weekly or monthly degree-day figures may also be used within an energy monitoring and targeting scheme to monitor the heating and cooling costs of climate controlled buildings, while annual figures can be used for estimating future costs. A degree day is computed as the integral of a function of time that generally varies with temperature. The ...
Energy use/Cost prediction HERS generate energy use and cost predictions for specific end uses like space heating/cooling, hot water and for whole house. These outputs are obtained in absolute measures and unlike to score rating these outputs can be used to compare houses like that of miles-per-gallon ratings are used to compare the cars.
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. [1]
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.
