IfcWaterProperties

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

Attribute definitions:

IsPotable | : | If TRUE, then the water is considered potable.
Hardness | : | Water hardness as positive, multivalent ion concentration in the water (usually concentrations of calcium and magnesium ions in terms of calcium carbonate).
AlkalinityConcentration | : | Maximum alkalinity concentration (maximum sum of concentrations of each of the negative ions substances measured as CaCO3).
AcidityConcentration | : | Maximum CaCO3 equivalent that would neutralize the acid.
ImpuritiesContent | : | 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.
PHLevel | : | Maximum water ph in a range from 0-14.
DissolvedSolidsContent | : | 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.
