Hello, I am currently seeking advice regarding modelling different fenestration setups and analysing there respective outputs on cooling and heating.

Using the theoretical glass [207] that Openstudio’s provides, I have tried to see the difference single pane, double pane and low emissivity glass would have by changing the respective conditions in the constructions tab in Openstudio’s but haven’t seen any changes in the buildings cooling or heating loads.

Has anyone come across this problem or would perhaps have some advice going forward on how best to analyse different window configuration? Any help would be greatly appreciated, cheers!
