3.3.3 Receptacle and Process Loads

Inputs for receptacle and process loads are specified at the space level (see specification below). In those instances when thermal blocks contain just one space, the inputs here will be identical to the inputs for the single space that is contained within the thermal block.

For those instances when a thermal block contains more than one space, the software shall either model the receptacle and process loads separate for each space and sum energy consumption and heat gain for each time step of the analysis or it must incorporate some procedure to sum inputs or calculate weighted averages such that the receptacle and process loads used at the thermal block level are equal to the combination of receptacle and process loads for each of the spaces contained in the thermal block.

When the spaces contained in a thermal block have different schedules, combining receptacle and process loads from the space level may be challenging and would have to be done at the level of each time step in the simulation. See discussion above on lighting.

Inputs for receptacle and process loads are specified at the space level (see specification below). In those instances when thermal zones contain just one space, the inputs here will be identical to the inputs for the single space that is contained within the thermal zone.

For those instances when a thermal zone contains more than one space, the software shall either (1) model the receptacle and process loads separately for each space and sum energy consumption and heat gain for each timestep of the analysis or (2) incorporate a procedure to sum inputs or calculate weighted averages such that the receptacle and process loads used at the thermal zone level are equal to the combination of receptacle and process loads for each of the spaces contained in the thermal zone.

When the spaces contained in a thermal zone have different schedules, combining receptacle and process loads from the space level may be challenging and would have to be done at the level of each timestep in the simulation. See discussion above on lighting.
