Yet another exhaust question

NC-2009 EAc1: Optimize Energy Performance
posted by Lawrence Lile on Apr 17, 2015, 5:54 pm

We've got an 11,000 square foot maintenance garage for trucks, modeling it under LEED and ASHRAE 90.1-2007. This is a tricky space.

It has more than 15 BTUH/SFT of heat so according to...

Room exhaust fan energy process or not?

NC-2009 EAc1: Optimize Energy Performance
posted by Haojie Wang on Mar 19, 2015, 2:49 pm

I remember seeing from somewhere that if the exhaust fan is not interlocked with the HVAC, it should be considered a process load and modeled the same in proposed and baseline. Could someone...

Interstitial or Interior Blinds

NC-2009 EAc1: Optimize Energy Performance
posted by Sandra Lester on Mar 14, 2015, 10:38 am

Would interstitial or interior blinds could contribute to load reductions and contribute to an increase in energy efficiency? What if the blinds are automated and these controls cannot be...
