6.2.4.24.2 Applicable entities

6.2.4.24.3 Properties

Name Property Type Data Type Description
CoolingDesignAirFlow IfcPropertySingleValue IfcVolumetricFlowRateMeasure

The air flowrate required during the peak cooling conditions.

HeatingDesignAirFlow IfcPropertySingleValue IfcVolumetricFlowRateMeasure

The air flowrate required during the peak heating conditions, but could also be determined by minimum ventilation requirement or minimum air change requirements.

SensibleHeatGain IfcPropertySingleValue IfcPowerMeasure

The sensible heat or energy gained by the space during the peak conditions.

TotalHeatGain IfcPropertySingleValue IfcPowerMeasure

The total (sensible+latent) amount of heat or energy gained by the space at the time of the space's peak cooling conditions.

TotalHeatLoss IfcPropertySingleValue IfcPowerMeasure

The total amount of heat or energy lost by the space at the time of the space's peak heating conditions.

CoolingDryBulb IfcPropertySingleValue IfcThermodynamicTemperatureMeasure

Dry bulb temperature, usually for for cooling design.

CoolingRelativeHumidity IfcPropertySingleValue IfcPositiveRatioMeasure

Inside relative humidity for cooling design.

HeatingDryBulb IfcPropertySingleValue IfcThermodynamicTemperatureMeasure

Dry bulb temperature for heating design.

HeatingRelativeHumidity IfcPropertySingleValue IfcPositiveRatioMeasure

Inside relative humidity for heating design.

VentilationDesignAirFlow IfcPropertySingleValue IfcVolumetricFlowRateMeasure

Ventilation outside air requirement for the space.

DesignAirFlow IfcPropertySingleValue IfcVolumetricFlowRateMeasure

Design air flow rate for the space.

CeilingRAPlenum IfcPropertySingleValue IfcBoolean

Ceiling plenum used for return air or not. TRUE = Yes, FALSE = No.

BoundaryAreaHeatLoss IfcPropertySingleValue IfcHeatFluxDensityMeasure

Heat loss per unit area for the boundary object. This is a design input value for use in the absence of calculated load data.
