blockDiffuseIsotropic
Diffuse solar irradiation on a tilted surface with an isotropic sky model
Extends from Buildings.BoundaryConditions.SolarIrradiation.BaseClasses.PartialSolarIrradiation.
Information
This component computes the hemispherical diffuse irradiation on a tilted surface using an isotropic model. The irradiation is a sum composed of diffuse solar irradiation and radiation reflected by the ground. For a definition of the parameters, see the User's Guide.
