The energy performance of appliances (or plug loads) and other electrical equipment is influenced by a number of factors. These typically include the number of hours that the equipment is operating, the electricity load of the equipment itself and the duty cycle (on/off cycling) for each appliance or other electrical equipment. Refer to the Appliances and Electrical Equipment Examples for more information.

Software & Data
The RETScreen Software Electrical Equipment Model can be used worldwide to evaluate the energy use and savings, costs, emission reductions, financial viability and risk for electrical appliances and equipment energy efficiency measures. The software can model a wide variety of projects ranging from replacement of used appliances (e.g. dishwashers, refrigerators, clothes dryers, dehumidifiers, etc.) by energy-efficient ones in houses and commercial and institutional buildings, to installation of automatic shut-off devices for electrical office equipment such as computers, monitors, printers, scanners and photocopiers in commercial and institutional buildings, to installation of variable speed or multiple-speed motors for pumps and fans in industrial facilities. The model also calculates the cross-effects of other energy efficiency measures employed in the facility (e.g. heating and cooling impact of installing energy-efficient computers). In addition, an Appliances & equipment tool is provided to determine the typical electricity load for various appliances and electrical equipment. The software (available in multiple languages) also includes product, project and climate databases, and a detailed user manual.
