Compute the direct solar irradiation transmited through a glazing surface considering the incidence angle
Hypothesis and equations
none
Bibliography
Relations from RT2000 (french building regulation), Fauconnier, Cardonnel [1983] and proportional weighting of cos i.
Instructions for use
This model returns the direct irradiation according to the incident irradiation. This information is provided through the FLUX input connector and could be calculated by a solar preprocessing (e.g. FLUXSurf model)
Known limits / Use precautions
none
