Cooling Load Factors: surface_absorptance
ASHRAE cooling load calculation factors — people heat gain, lighting power density, luminaire heat fractions, motor efficiency, cooking/warewashing appliance heat gain, office/computer equipment heat gain, glazing optical properties, radiative/convective fractions, surface solar absorptance, wall and roof conduction time series (CTS), construction material layer properties, radiant time series (RTS), zone characteristics, and below-grade heat transfer coefficients.
