modelExteriorSolarAbsorption
Shortwave radiation absorption on an exterior surface
Information
Transmitted shortwave solar radiation is distributed over all surfaces in the zone in a prescribed scale. This scale is an input value which may be dependent on the shape of the zone and the location of the windows, but literature [Liesen 1997] shows that the overall model is not significantly sensitive to this assumption.
