"Conditioned Space?"- Free cooling with outside air

NC-2009 EAp2: Minimum Energy Performance
posted by Victoria Watson on Dec 19, 2014, 10:20 pm

Hi,
I am not sure whether to class mechanical rooms which are free cooled by outside air as "conditioned" for the purpose of the baseline (so the baseline would be on system 5 in this...

New Construction vs Major Renovation

NC-2009 EAp2: Minimum Energy Performance
posted by Ritwik Kakati on Dec 18, 2014, 5:31 pm

Our project consists of renovation of 140,000 SF of an existing building, as well as the addition of 30,000 SF of new space. For whole building energy simulation, I see minimum requirement of 10...
