Openings tab in model data
You can enter Wind pressure coefficients (WPC) for wind incidence angles in 45° increments for each surface in the model. DesignBuilder automatically sets up default WPC data as surfaces are created using published Wind Pressure Coefficient template data.
Wind pressure coefficients are only available when using the Calculated natural ventilation model option.
Note: the wind incidence angles are relative to the surface normal for each surface.
