Dear Caroline:The area that you specify is the total area of the window, including frame. The window heat transfer coefficient (u-value) and energy exchanges are calculated taking into account the ratio of frame area to total area. Please refer to Volume 6-Multizone Building Modeling with Type56 and TRNBuild, part 2, section 2.2, for the description of the window model.

Helo,I was wondering about a simple thing: If I define in Prebid (not in the window library) the area for a window, doI have to define the area for the whole window (glass + frame), or do I define just the area of the glass? Any hint would be appreciated, regards, Caroline
