The International Performance Measurement and Verification Protocol (IPMVP®) defines standard terms and suggests best practise for quantifying the results of energy efficiency investments and increase investment in energy and water efficiency, demand management and renewable energy projects. [1]
The Home Energy Rating is an American estimated measurement of a home's energy efficiency based on normalized modified end-use loads (nMEULs). [1] In the United States, the Residential Energy Services Network (RESNET) is responsible for creation and maintenance of the RESNET Mortgage Industry National Home Energy Rating Standards (MINHERS), a proprietary system of standards, [2] which includes ...
Common energy efficiency label on appliances to indicate their energy efficiency in a clear manner. Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems.
The wall-plug efficiency is the measure of output radiative-energy, in watts (joules per second), per total input electrical energy in watts. The output energy is usually measured in terms of absolute irradiance and the wall-plug efficiency is given as a percentage of the total input energy, with the inverse percentage representing the losses.
Measurement and verification (M&V) is the term given to the process for quantifying savings delivered by an Energy Conservation Measure (ECM), as well as the sub-sector of the energy industry involved with this practice. [1] Measurement and verification demonstrates how much energy the ECM has avoided using, rather than the total cost saved ...
In computing, performance per watt is a measure of the energy efficiency of a particular computer architecture or computer hardware.Literally, it measures the rate of computation that can be delivered by a computer for every watt of power consumed.
The energy efficiency rating in this HERS represents the predicted energy consumption, represents the form of normalized annual energy consumption. This rating scheme consist a detailed measure of CFLs, water heater tanks, ceiling, floors and pipe insulation , efficient refrigerator and freezer, high efficient space and water heating equipments ...
Luminous efficiency, a measure of how well a light source produces visible light; Fuel efficiency, the efficiency of converting potential energy in a fuel into kinetic energy; Energy efficiency in transportation, the fuel economy of various modes of transportation; Energy-efficient landscaping, a type of landscaping designed for the purpose of ...
