8.10.4.11.2 Applicable entities

8.10.4.11.3 Properties

Name Property Type Data Type Description
IsPotable IfcPropertySingleValue IfcBoolean

If TRUE, then the water is considered potable.

Hardness IfcPropertySingleValue IfcIonConcentrationMeasure

Water hardness as positive, multivalent ion concentration in the water (usually concentrations of calcium and magnesium ions in terms of calcium carbonate).

AlkalinityConcentration IfcPropertySingleValue IfcIonConcentrationMeasure

Maximum alkalinity concentration (maximum sum of concentrations of each of the negative ions substances measured as CaCO3).

AcidityConcentration IfcPropertySingleValue IfcIonConcentrationMeasure

Maximum CaCO3 equivalent that would neutralize the acid.

ImpuritiesContent IfcPropertySingleValue IfcNormalisedRatioMeasure

Fraction of impurities such as dust to the total amount of water. This is measured in weight of impurities per weight of water and is therefore unitless.

DissolvedSolidsContent IfcPropertySingleValue IfcNormalisedRatioMeasure

Fraction of the dissolved solids to the total amount of water. This is measured in weight of dissolved solids per weight of water and is therefore unitless.

PHLevel IfcPropertySingleValue IfcPHMeasure

Maximum water PH in a range from 0-14.
