The first of the cooling load factors used in this method is the CLTD, or the Cooling Load Temperature Difference. This factor is used to represent the temperature difference between indoor and outdoor air with the inclusion of the heating effects of solar radiation. [1] [5] The second factor is the CLF, or the cooling load factor.
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 ...
The purpose of the IPMVP is to increase certainty, reliability, and level of savings; reduce transaction costs by providing an international, industry consensus approach and methodologies; reduce financing costs by providing a project with a Measurement and Verification Plan (M&V Plan) standardisation, thereby allowing project bundling and pooled project financing.
Degree days are a useful metric for estimating energy consumption required for household heating and cooling, and in this context are formally referred to as heating degree days. Since the escape or ingress of heat due to conduction is proportional to the difference between the indoor and outdoor temperature, the amount of energy needed to ...
The building balance point temperature is the outdoor air temperature when the heat gains of the building are equal to the heat losses. [1] Internal heat sources due to electric lighting, mechanical equipment, body heat, and solar radiation may offset the need for additional heating although the outdoor temperature may be below the thermostat set-point temperature.
HeatIT - Free (light) version of Pinch Analysis software that runs in Excel - developed by Pinchco, a consultancy company offering expert advice on energy related matters Simulis Pinch - Tool from ProSim SA that can be used directly in Excel and that is dedicated to the diagnosis and the energy integration of the processes.
Sol-air temperature (T sol-air) is a variable used to calculate cooling load of a building and determine the total heat gain through exterior surfaces. It is an improvement over: It is an improvement over:
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). [1] [2] It therefore has units of BTU ...
