just ran a typical office (250,000 sf) in Fresno, CA in eQuest. When I put
2.5 ft fins on all the windows, I got a slight decrease in heating as well (but
not to your % level).</SPAN></FONT></FONT></FONT></DIV>

15% decrease in cooling, and a 13% decrease in heating. This building is
dominated by VAV/reheat. What I can surmise is that when the cooling load
decreased, the need to reheat decreased as well. That the building is not skin
dominated for energy.</SPAN></FONT></FONT></FONT></DIV>

<DIV>The Questions:</DIV>
<DIV>1. Its very baffling to see the heating consumption go down too. I wanted
to see an increase in heating on implementing the shading devices. How can I
justify that decrease?</DIV>
<DIV> </DIV>
<DIV>2. The building has a total area of 210273 sqft. with 15 ft deep perimeter
zones. The shading reduces the energy consumption by 5 to 6 %. Is that
acceptable?</DIV>
<DIV> </DIV>
<DIV>Any help is greatly appreciated.</DIV>
<DIV>Thank you </DIV>
