Schedules for power (like computers and coffee machines), lighting, and occupancy allow the user to specify which hours of the day to use these loads and at what percentage. These schedules are sent to the engine either directly through parameters on the space's type (see above).
Equipment and lighting both contribute a sensible heat gain directly given by the amount of power they emit. Lighting also may contribute to any plenums that serve a given space and so a percentage of this contribution is taken in to account within the engine. This value can be specified in the Electrical Loads section of a space or by the space's type.
In addition to sensible heat gain, people also give off a latent heat gain. This latent gain is instantaneous, while the sensible gain (like those for appliances) is affected by the thermal storage characteristics of the space.
