eQuest - Energy consumption increasing on reducing Glass U-Value

Hi There

I am facing an issue in eQuest in almost all simulation models for most hot
and composite indian climates. Whenever we reduce U-value of glass in
model, from Single Glazing U-Value of 1 Btu/hr Sqft F to 0.32 Btu/hr Sqft F
(or any other U-value lower than 1), we see an increase in energy
consumption.

Can someone point out principal mistake that may be making in the model.

Thanks in advance.
