Useful Energy Intensity
See also: Analysis View, Demand Analysis, Useful Energy Demand Analysis
The useful energy intensity screen only appears when conducting a useful energy analysis and is only defined at Category with Energy Intensity branch types () .
Unlike a final energy intensity, which specifies the amount of fuel used per unit of activity, a useful energy intensity is a measure of the energy service provided per unit of activity -- the "useful" energy. Examples include the heating load of a building (NOT the fuel used in its boilers) or the amount of heat in a cooking pot required to cook a meal (NOT the amount of wood burnt).
Useful energy intensities are calculated for Current Accounts based on the fuel shares and efficiencies of devices. This calculated value is displayed for you to project into the future when editing scenarios.
Refer to Useful Energy Demand Analysis for information on how to configure branches for entering useful energy intensities.
Note: Because they are not associated with a particular fuel, LEAP only lets you enter useful energy intensities in energy units.
