<P class=MsoNormal>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?</P></DIV>
