Greetings, Vipin;
I opened your GSHP project here, and ran it with a weather file for
Rochester, NY, USA. The winters are quite cold here, and as I thought,
it shows some heating in a consistent fashion between November and
April. However, as you can see below, miscellaneous equipment energy far
outweighs this. This is very unusual. This means there are plug loads
within your building which are also heating the building. In fact, you
have 6.9 W/sq. ft. entered as the load. I would suggest reducing this
amount to about 1.2 w/sf for a typical office.
Cheers,
Eric
Eric, thanks for the pictorial!
I'd agree with Eric's assessment and offer extra food for
thought/context: I believe 90.1-2007 users manual suggests 0.75 W/SF as
typical for office building plug loads.
Further qualitative perspective: Picture how hot a 60W incandescent
A-lamp gets... Now imagine 60W light bulbs on a 10ft grid all turned
on... that (6W/SF) is a significant amount of heat!
