This checkbox defines whether any shading plane surface objects imported from a model via gbXML or IDF should be applied to the DesignBuilder model. Enabled shade surfaces will be listed in the Navigator, displayed on the Edit screen as planes of various colours, rendered on the Visualisation screen and included in Radiance daylighting and EnergyPlus simulations as shading surfaces. The only type of surface currently supported are shading plane surfaces.
Shade surfaces that are not selected are not removed from the model entirely and can be displayed again by changing the selection on this dialog.
Note: When shade surface planes are being shown, the Component block shades and reflects option on the Constructions tab can be unchecked to prevent all or just particular planes from being included in the EnergyPlus simulations.
Note: Shading plane surfaces do not have any impact on external CFD analyses.
