Hello all,

I've been beating my head in trying to get my design heating load down. I have been looking at the neat little summary tab for the air side hvac. Having been unable to get the heating load to be lower than ~60 (Btu/h per sf) or even lower that the cooling load, I decided to look at the detailed report. Looking at the  SS-D report I see that the maximum heating load works out to be approximately 34(Btu/h per sf)! Is that correct? Where does the summery tab get its information?

Another way to check whether my heating is reasonable is to check the annual use, I assume. The only problem is I have no idea what that is. Currently the system uses 830 MBtu. Any help would be great!

thanks
