Guardian Glass for BIM supports roof and floor overhangs in Mass and Detailed models. A canopy may be used in mass models to achieve this affect. In Detailed Models, when a Roof or Floor is extended beyond the Building Line and Shading Factors are turned on in the Building Manager, the Heat Gain results will be reduced.
Note: If a Roof is extended as a shade device, the roof area will not increase when displayed in the Building Manager since this extended area is categorized as a Shade Surface by Revit’s Energy Analysis. This will also apply to Floor Areas (It is good practice to model these floors with external functions).
Note: Both Solar Loads and Daylighting will be affected by geometry changes in the model such as this. Daylighting will be affected since this element did not exist before.
