Description

UpperVaporResistanceFactor

P_SINGLEVALUE / IfcPositiveRatioMeasure

Upper Vapor Resistance Factor

The vapor permeability relationship of air/material (typically value > 1), measured in high relative humidity (typically in 95/50 % RH).

LowerVaporResistanceFactor

P_SINGLEVALUE / IfcPositiveRatioMeasure

Lower Vapor Resistance Factor

The vapor permeability relationship of air/material (typically value > 1), measured in low relative humidity (typically in 0/50 % RH).

IsothermalMoistureCapacity

P_SINGLEVALUE / IfcIsothermalMoistureCapacityMeasure

Isothermal Moisture Capacity

Based on water vapor density.

VaporPermeability

P_SINGLEVALUE / IfcVaporPermeabilityMeasure

Vapor Permeability

The rate of water vapor transmission per unit area per unit of vapor pressure differential under test conditions.

MoistureDiffusivity

P_SINGLEVALUE / IfcMoistureDiffusivityMeasure

Moisture Diffusivity

Moisture diffusivity is a transport property that is frequently used in the hygrothermal analysis of building envelope components.
