Hi,

I am designing in DD wizard and I need to check effect on cooling load with
increase in R value of roof and wall.
Climate zone- 1A

But i am getting strange result by gradually increasing resistance from 1
to 2 to3 and so on, I am getting increase space cool consumption.

The design and schedule value are default with change in Chiller parameter.

Any idea why is it so ?
I dont think it is due to excess heat generated inside.

Kind Regards
