Name Property Type Data Type Description
TemperatureSetPoint IfcPropertySingleValue IfcThermodynamicTemperatureMeasure

The temperature setpoint range and default setpoint.

TemperatureMax IfcPropertySingleValue IfcThermodynamicTemperatureMeasure

Maximal temperature of the space or zone, that is required from user/designer view point. If no summer or winter space temperature requirements are given, it applies all year, otherwise for the intermediate period.

TemperatureMin IfcPropertySingleValue IfcThermodynamicTemperatureMeasure

Minimal temperature of the space or zone, that is required from user/designer view point. If no summer or winter space temperature requirements are given, it applies all year, otherwise for the intermediate period.

TemperatureSummerMax IfcPropertySingleValue IfcThermodynamicTemperatureMeasure

Maximal temperature of the space or zone for the hot (summer) period, that is required from user/designer view point and provided as requirement for cooling.

TemperatureSummerMin IfcPropertySingleValue IfcThermodynamicTemperatureMeasure

Minimal temperature of the space or zone for the hot (summer) period, that is required from user/designer view point and provided as requirement for cooling.

TemperatureWinterMax IfcPropertySingleValue IfcThermodynamicTemperatureMeasure

Maximal temperature of the space or zone for the cold (winter) period, that is required from user/designer view point and provided as requirement for heating.

TemperatureWinterMin IfcPropertySingleValue IfcThermodynamicTemperatureMeasure

Minimal temperature of the space or zone for the cold (winter) period, that is required from user/designer view point and provided as requirement for heating.

HumiditySetPoint IfcPropertySingleValue IfcPositiveRatioMeasure

Required Humidity Set Point.

HumidityMax IfcPropertySingleValue IfcPositiveRatioMeasure

Maximum allowed humidity.

HumidityMin IfcPropertySingleValue IfcPositiveRatioMeasure

Minimum required humidity.

HumiditySummer IfcPropertySingleValue IfcPositiveRatioMeasure

Required humidity in summer.

HumidityWinter IfcPropertySingleValue IfcPositiveRatioMeasure

Required humidity in winter.

DiscontinuedHeating IfcPropertySingleValue IfcBoolean

Indication whether discontinued heating is required/desirable from user/designer view point. (TRUE) if yes, (FALSE) otherwise.

NaturalVentilation IfcPropertySingleValue IfcBoolean

Indication whether the space is required to have natural ventilation (TRUE) or mechanical ventilation (FALSE).

NaturalVentilationRate IfcPropertySingleValue IfcCountMeasure

Indication of the requirement of a particular natural air ventilation rate, given in air changes per hour.

MechanicalVentilation IfcPropertySingleValue IfcBoolean

Mechanical Ventilation

MechanicalVentilationRate IfcPropertySingleValue IfcCountMeasure

Indication of the requirement of a particular mechanical air ventilation rate, given in air changes per hour.

AirConditioning IfcPropertySingleValue IfcBoolean

Indication whether this space requires air conditioning provided (TRUE) or not (FALSE).

AirConditioningCentral IfcPropertySingleValue IfcBoolean

Indication whether the space requires a central air conditioning provided (TRUE) or not (FALSE). It should only be given, if the property "AirConditioning" is set to TRUE.

AirHandlingName IfcPropertySingleValue IfcLabel

Name of the Air Handling unit or system.
