<P><FONT SIZE=2>Dear all,<BR>
<BR>
If you have a baseline and a proposed design of a school, and every single input box in the boiler specs and the hot water loop is the same in both, is it possible to get a very different space heating consumption?!<BR>
This has made me crazy, one consumption is 4 times the other.<BR>
I checked the schedules, schedules of operation, everything is the same! I tried a scenario where the boiler capacities are kept to default (autosize) and another scenario where I inputted the same number (1.5 MBtu/h). I am getting really different results. Is there any other variable that I may not be paying attention to?<BR>
<BR>
The electricity consumption in the proposed is around 15% less than the baseline, but why is the gas consumption (space heating only) 4 times more?<BR>
<BR>
Many thanks,<BR>
Omar<BR>
