The results may be accurate, I have found that over insulating can cause the
cooling load to increase if there are internal loads.

Same way you can get over heated in the winter if you are scooping snow.
Losing energy thru the wall isn't always bad.

Subject: [Equest-users] Adding Insulation to existing building

I have an existing 360' X 140' metal building with offices at one end. They
have the standard 4" thick insulation trapped between girts and panels. In my
building simulation eQuest got within 5% of actual utility bills, but when I
started adding insulation the model gas heating bill went down and the
electric cooling bill went up. Any ideas what I am doing wrong?
Thanks
