5.2.4 Roof / Floor Overhangs

2 minutesread

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 results will be different.

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.

Note: Both Solar Loads and Daylighting will be affected by geometry changes in the model such as this.
