Hi all,

I'm trying to model a building in eQuest that has both punched opening windows with single pane glass AND an IGU curtain wall.  The internal punched opening windows are existing, the curtain wall is proposed.  I'm using Optics5 and Window5 to get the R-value and SHGC for the curtain wall, I'm just not sure how to accurately model a building with two separate glazing systems. The goal of this exercise is to determine the impact different glazing units in the curtain wall have on the building's energy consumption.

I've included a section below showing the IGU on the left and 2 floors with punched opening windows on the right.  Thanks in advance for your assistance.
