IFC (IFC4X3_ADD1) development Pset_SpaceHeaterTypeCommon Semantic definition

Space heater type common attributes. SoundLevel attribute deleted in IFC2x2 Pset Addendum: Use IfcSoundProperties instead. Properties added in IFC4. Applicable entities Properties

Name Property Type Data Type Description
Reference IfcPropertySingleValue IfcIdentifier

Reference ID for this specified type in this project (e.g. type 'A-1'), Also referred to as "construction type". It should be provided as an alternative to the name of the "object type", if the software does not support object types and no classification reference to a recognized classification system used.

Status IfcPropertyEnumeratedValue PEnum_ElementStatus

Status of the element, predominately used in renovation or retrofitting projects. The status can be assigned to as "New" - element designed as new addition, "Existing" - element exists and remains, "Demolish" - element existed but is to be demolished, "Temporary" - element will exists only temporary (like a temporary support structure).

SpaceHeaterPlacement IfcPropertyEnumeratedValue PEnum_SpaceHeaterPlacementType

Indicates how the space heater is designed to be placed.

TemperatureClassification IfcPropertyEnumeratedValue PEnum_SpaceHeaterTemperatureClassification

Enumeration defining the temperature classification of the space heater surface temperature. low temperature - surface temperature is relatively low, usually heated by hot water or electricity. high temperature - surface temperature is relatively high, usually heated by gas or steam.

HeatTransferDimension IfcPropertyEnumeratedValue PEnum_SpaceHeaterHeatTransferDimension

Indicates how heat is transmitted according to the shape of the space heater.

HeatTransferMedium IfcPropertyEnumeratedValue PEnum_HeatTransferMedium

Enumeration defining the heat transfer medium if applicable.

EnergySource IfcPropertyEnumeratedValue PEnum_EnergySource

Enumeration defining the energy source or fuel cumbusted.

Note: hydronic heaters shall use UNSET; dual-use hydronic/electric heaters shall use ELECTRICITY.

BodyMass IfcPropertySingleValue IfcMassMeasure

Overall body mass of the heater.

ThermalMassHeatCapacity IfcPropertySingleValue IfcReal

Product of component mass and specific heat.

OutputCapacity IfcPropertySingleValue IfcPowerMeasure

Total nominal heat output as listed by the manufacturer.

ThermalEfficiency IfcPropertySingleValue IfcNormalisedRatioMeasure

Overall Thermal Efficiency is defined as gross energy output of the heat transfer device divided by the energy input.

NumberOfPanels IfcPropertySingleValue IfcCountMeasure

Number of panels.

NumberOfSections IfcPropertySingleValue IfcCountMeasure

Number of sections.

Number of vertical sections, measured in the direction of flow.
