modelIsotropicAndPerezDiffuseRadiation
Partial model to run BESTEST validation case studies for weather data processing
Extends from Buildings.BoundaryConditions.SolarIrradiation.BaseClasses.PartialSolarIrradiation (Partial model that is used to compute the direct and diffuse solar irradiation).
Information
This model outputs the global radiation with a certain inclination and orientation
using the isotropic sky model and the Perez sky model. The variable H is
the global radiation calculated using the isotropic sky model, while HPer is
the global radiation calculated using the Perez sky model.
