I'm working on an energy model for a high-rise project in the Pacific NW that has office and residential, with residential being the top two-thirds of the building.

Shadow Boxes: Counts as Fenestration or Opaque Surface?

NC-v4 EAp2:Minimum energy performance
posted by  Waleed AlGhamdi  on 

Spandrel panels are considered as opaque surfaces per the ASHRAE 90.1 definition. Kalwall and similar products count as fenestration since they allow in light.
