Example that simulates a predefined thermal building model with 1 zone, based on 1D-discretized building elements. The areas of window1 (included in wall1) and window3 (included in wall3) are set to zero. Further wall1 is definend as an adiabatic wall and the outer surface temperature of wall3 is set to 20 degree Celsius. The soil temperature under the building is set to 10 degree Celsius. window4 on the south facade is shaded by an horizontal overhang.
