modelSkyRadiationExchange
Radiative heat exchange with the sky and the ambient
Extends from Buildings.BaseClasses.BaseIcon (Base icon).
Information
This model computes the infrared radiative heat flow between exterior building surfaces and the ambient. The ambient consists of the sky black-body radiation and the outdoor temperature (which is used as an approximation to the surface temperature of the ground and neighboring buildings).Parameters
