omegalpes.energy.buildings.thermal.lookup_effective_mass_area_factor(cm)[source]

Look up the factor to multiply the conditioned floor area by to get the effective mass area by building construction type. This is used for the calculation of the effective mass area “Am” in get_prop_RC_model. Standard values can be found in the Annex G of ISO EN13790

param:

cm: The internal heat capacity per unit of area [J/m2].

return:

Effective mass area factor (0, 2.5 or 3.2 depending on cm value).
