6.2.4.25.1 Semantic definition

The space thermal load defines all thermal losses and gains occurring within a space or zone. The thermal load source attribute defines an enumeration of possible sources of the thermal load. The maximum, minimum, time series and app

6.2.4.25.3 Properties

Name	Property Type	Data Type	Description
People	IfcPropertyBoundedValue	IfcPowerMeasure	Heat gains and losses from people.
Lighting	IfcPropertyBoundedValue	IfcPowerMeasure	Lighting loads.
EquipmentSensible	IfcPropertyBoundedValue	IfcPowerMeasure	Heat gains and losses from equipment.
VentilationIndoorAir	IfcPropertyBoundedValue	IfcPowerMeasure	Ventilation loads from indoor air.
VentilationOutdoorAir	IfcPropertyBoundedValue	IfcPowerMeasure	Ventilation loads from outdoor air.
RecirculatedAir	IfcPropertyBoundedValue	IfcPowerMeasure	Loads from recirculated air.
ExhaustAir	IfcPropertyBoundedValue	IfcPowerMeasure	Loads from exhaust air.
AirExchangeRate	IfcPropertyBoundedValue	IfcPowerMeasure	Loads from the air exchange rate.
DryBulbTemperature	IfcPropertyBoundedValue	IfcPowerMeasure	Dry bulb temperature of the object. Loads from the dry bulb temperature.
RelativeHumidity	IfcPropertyBoundedValue	IfcPowerMeasure	Loads from the relative humidity.
InfiltrationSensible	IfcPropertyBoundedValue	IfcPowerMeasure	Heat gains and losses from infiltration.
TotalSensibleLoad	IfcPropertyBoundedValue	IfcPowerMeasure	Total energy added or removed from air that affects its temperature. If a value is less than zero (negative), then the thermal load is lost from the space. If a value is greater than zero (positive), then the thermal load is a gain to the space.
TotalLatentLoad	IfcPropertyBoundedValue	IfcPowerMeasure	Total energy added or removed from air that affects its humidity or concentration of water vapor. If a value is less than zero (negative), then the thermal load is lost from the space. If a value is greater than zero (positive), then the thermal load is a gain to the space.
TotalRadiantLoad	IfcPropertyBoundedValue	IfcPowerMeasure	Total electromagnetic energy added or removed by emission or absorption. If a value is less than zero (negative), then the thermal load is lost from the space. If a value is greater than zero (positive), then the thermal load is a gain to the space.
