I want to model a window in a wall and I am using the E+ window material component because I only know the thermal properties for the glazing unit assembly. However, my window, in reality, has a lot of frame (27%) and I would like to be able to account for that so that my solar gain is accordingly reduced. Is there a way for me to specify how much frame area I want (as an extra script for example).
Other work arounds I have tried:
I tried to make a part of the wall that has the properties of a frame and add the glazing to that (but then I assume I am getting a lot of frame because I’m not sure how much I get as a default). And then add another wall around the frame part (this runs but I get the warning that the surface overlap and the solar gain calculation will be wrong)
I have tried to reduce the total g value by calculating an averaged weighted value considering the frame is opaque and the g value of the glazed part.
I feel like both these options aren’t great and so I would be very grateful if I can simply change the % of frame at the beginning. Also, I’m not really interested in using the therm components unless I really have to, because as I said I don’t have a lot of the detailed properties available.
Thank you for your help
