7.5.4.11.3 Properties

Name Property Type Data Type Description
NominalEfficiency IfcPropertyTableValue IfcNormalisedRatioMeasure/IfcThermodynamicTemperatureMeasure

Nominal object efficiency under nominal conditions.

The nominal efficiency of the boiler as defined by the manufacturer. For water boilers, a function of inlet versus outlet temperature. Note: as two variables are used, DefiningValues and DefinedValues are null, and values are stored in IfcTable in the following order: InletTemperature(IfcThermodynamicTemperatureMeasure), OutletTemperature(IfcThermodynamicTemperatureMeasure), NominalEfficiency(IfcNormalizedRatioMeasure). The IfcTable is related to IfcPropertyTableValue using IfcMetric and IfcPropertyConstraintRelationship.

HeatOutput IfcPropertyTableValue IfcEnergyMeasure/IfcThermodynamicTemperatureMeasure

Total nominal heat output as listed by the Boiler manufacturer.

For water boilers, it is a function of inlet versus outlet temperature. For steam boilers, it is a function of inlet temperature versus steam pressure. Note: as two variables are used, DefiningValues and DefinedValues are null, and values are stored in IfcTable in the following order: InletTemperature(IfcThermodynamicTemperatureMeasure), OutletTemperature(IfcThermodynamicTemperatureMeasure), HeatOutput(IfcEnergyMeasure). The IfcTable is related to IfcPropertyTableValue using IfcMetric and IfcPropertyConstraintRelationship.
