Buildings.BoundaryConditions.SolarIrradiation.Examples.DiffuseIsotropic
Test model for diffuse solar irradiation on a tilted surface using the isotropic model
Information
This example computes the hemispherical diffuse irradiation on a roof, wall and a floor, using an isotropic sky model. Since the floor only sees the ground, it receives the lowest amount of diffuse solar irradiation.

Buildings.BoundaryConditions.SolarIrradiation.Examples.DiffusePerez
Test model for diffuse solar irradiation on a tilted surface using the Perez model
Information
This model tests the implementation of Perez' model for diffuse solar radiation. The three instances of Perez' model compute the diffuse solar irradiation on a roof, a wall and a floor. Since the floor only sees the ground but not the radiative heat flow that is scattered in the atmosphere, it receives the lowest amount of diffuse solar irradiation.

Buildings.BoundaryConditions.SolarIrradiation.Examples.DirectTiltedSurface
Test model for direct solar irradiation on a tilted surface
Information
This model tests the direct solar irradiation received on a ceiling, a wall and a floor. The assert statement will stop the simulation if the floor receives any direct solar irradiation.
