Horizontal Ceiling - TBC

Projecting a roof is useful when a building’s thermal envelope extends beyond the ceiling line, either up to the roof line or into another zone above. This allows you to model more realistic volumes, especially in spaces like lofts, atriums or vaulted ceilings.

Project a Roof

To project a roof, first navigate to the zone you want to modify. This can be done for one or several zones, offering flexibility depending on your design. In the drawing space, select the zone and open the zone panel. Click on 'Using Envelope Settings' in the left panel and then navigate to the tab 'Ceiling'. Under ‘Ceiling Method’, choose the appropriate method for how ceilings are assigned. Select ‘Projected’ to extend the zone volume up to the external roof line.
