RE: [EnergyPlus_Support] Roof modeling



Thank you for the quick response.

Also, the roof has sizable overhangs on all sides. According to the user
manual, roof extensions/ overhangs do not need to be modeled as separate
shading surfaces. If I understand correctly, EnergyPlus determines the
portion that extends beyond the walls (using entered wall and roof vertices)
to calculate shading effects. Since the roof will be divided into sections
covering several zones, will an overhang associated with a particular roof
section be limited to shading only the wall(s) of the zone it belongs to?
Or, depending on the Sun's position, can it also shade the walls of other
zones?

It needs to be divided into surfaces covering each zone.

Can a roof spanning over several zones be modeled as one big 
rectangular heat transfer surface? Or, does it need to be divided into 
surfaces covering each zone? 
If the roof can be modeled as a single surface covering several zones, 
which zone name is entered under the  "InsideFaceEnvironment" field ?
