Substance

A physical substance with physical—i.e., optical, thermal—properties.

Note that, contrary to EnergyPlus' Materials, Substances do not contain information about the thickness, which in Simple is given when creating a Material. The idea is to enable multiple materials of different thicknesses to reference the same material.

Note: Glazing substances are Normal substances with solar_transmitance and visible_transmittance. However, contrary to all other properties, this property does depend on the thickness of the substance. So, in order to build a coherent Glazing, you'll need to match this Substance with an appropriate Material
