IfcFuelProperties

Definition from IAI: Common definition to capture the properties of fuel energy typically used within the context of building services and flow distribution systems.

HISTORY: New entity in Release IFC2x Edition 2.

EXPRESS specification:

ENTITY IfcFuelProperties
SUBTYPE OF ( IfcMaterialProperties);
CombustionTemperature  :  OPTIONAL IfcThermodynamicTemperatureMeasure;
CarbonContent  :  OPTIONAL IfcPositiveRatioMeasure;
LowerHeatingValue  :  OPTIONAL IfcHeatingValueMeasure;
HigherHeatingValue  :  OPTIONAL IfcHeatingValueMeasure;
UNIQUE
UR11  :  Material;
END_ENTITY;

Attribute definitions:

CombustionTemperature  :  Combustion temperature of the material when air is at 298 K and 100 kPa.
CarbonContent  :  The carbon content in the fuel. This is measured in weight of carbon per unit weight of fuel and is therefore unitless.
LowerHeatingValue  :  Lower Heating Value is defined as the amount of energy released (MJ/kg) when a fuel is burned completely, and H2O is in vapor form in the combustion products.
HigherHeatingValue  :  Higher Heating Value is defined as the amount of energy released (MJ/kg) when a fuel is burned completely, and H2O is in liquid form in the combustion products.
