The project I am working on is an office building that operates 20 hrs per day
with most of the loads occuring at night and low occupancy on daytime.?It is a
cooled by a DX roof unit and has a very high internal load. No heating equipment
is required because the building is in Climate 1. I was surprised that when I
changed my window U-value from 0.3 to 0.7 I got less cooling consumption. I
always thought that getting low?u-value will give me less coling consumption.
Can somebody tell me why I am getting less cooling when I use?a higher window
U-value?

Thanks,
