heat gain

[′hēt ‚gān]
(engineering)
The increase of heat within a given space as a result of direct heating by solar radiation and of heat radiated by other sources such as lights, equipment, or people.

Heat gain

Increase in the amount of heat in a space, including heat transferred from outside in the form of solar radiation, and heat generated within by people, lights, computers, copiers, mechanical systems, and other sources. This additional migration of heat into a space is accomplished by conduction, radiation, or the natural exchange of air. This increase in the amount of heat in a given space must be mitigated by air-conditioning.

heat gain

The net increase in heat within a space.
