Pset_MaterialCombustion A set of extended material properties of products of combustion generated by elements typically used within the context of building services and flow distribution systems. IfcMaterial IfcMaterial SpecificHeatCapacity Specific heat of the products of combustion: heat energy absorbed per temperature unit. Specific Heat Capacity N20Content Nitrous oxide (N2O) content of the products of combustion. This is measured in weight of N2O per unit weight and is therefore unitless. N20 Content COContent Carbon monoxide (CO) content of the products of combustion. This is measured in weight of CO per unit weight and is therefore unitless. COContent CO2Content Carbon dioxide (CO2) content of the products of combustion. This is measured in weight of CO2 per unit weight and is therefore unitless. CO2 Content
