Cleanroom Chase Area Classification

NC-v4 EAp2: Minimum Energy Performance
posted by Michael Hill on Nov 8, 2018, 2:37 pm

I am wondering if anyone knows if a cleanroom return chase would be counted in the conditioned floor area for determining the primary system type for ASHRAE 90.1. There is no intent to condition...

"with errata but without addenda"

The LEED v3 reference book already refers to ASHRAE 90.1 "with errata but without addenda."  The v4 book only says "with errata."  Does that imply that all addenda to ASHRAE 90.1 must be followed...

posted by Alfonzo Collins on Nov 6, 2018, 4:32 pm

I understand the energy model is based on ASHRAE 90.1, but is the LEED project building required to follow ASHRAE 90.1 as the energy code?  Here in NYC, we are allowed to follow either ASHRAE 90....

Fan power in Baseline

NC-v4 EAp2: Minimum Energy Performance
posted by Tanushree Charan on Oct 27, 2018, 8:48 pm

I wanted to understand what is the ballpark for the fan energy consumption for the ASHRAE 90.1 Baseline model for LEED v4. 

Is this number about 10% of the total energy consumption for the...

At issue, our proposed system (chilled water) is paired against a System 5 (non-residental < 5 floors & 25,000 < SQFT < 150,000) but we are having a problem with the energy modeling...
