Buildings.ThermalZones.ReducedOrder.SolarGain.CorrectionGDoublePane
Double pane window solar correction
Information
This model computes short-wave radiation through transparent elements with any orientation and inclination by means of solar transmission correction factors. Transmission properties of transparent elements are in general dependent on the solar incidence angle. To take this dependency into account, correction factors can be multiplied with the solar radiation. These factors should not be mistaken as calculation of solar radiation on tilted surfaces, calculation of g-values or consideration of sunblinds, as it is an additional step. The implemented calculations are defined in the German Guideline VDI 6007 Part 3 (VDI, 2015). The given model is only valid for double pane windows. The guideline describes also calculations for single pane and triple pane windows.
