I am working to model window improvements in a multifamily building tower. I have confirmed that the only difference between the models is the change of U-0.38 to U-0.20 windows, with a substantial window area on the tower.

When the change to U-0.20 windows is made cooling energy goes up which is unexpected. Has anyone experienced this issue? The models can be found here:
