7.5.4.11.1 Semantic definition

Water boiler type common attributes.

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(IfcNormalisedRatioMeasure). The IfcTable is related to IfcPropertyTableValue using IfcMetric and IfcResourceConstraintRelationship.
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 IfcResourceConstraintRelationship.

NominalEfficiency

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(IfcNormalisedRatioMeasure). The IfcTable is related to IfcPropertyTableValue using IfcMetric and IfcResourceConstraintRelationship.

HeatOutput

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 IfcResourceConstraintRelationship.
