[Equest-users] ER Wheel in Baseline

Tue Nov 29 13:44:18 PST 2016

Aru,

I may be reading the question wrong but the proposed case system does NOT dictate baseline case ERV requirements.  If the autosized baseline case systems meet the characteristics outlined in 90.1-2007(?) Section G3.1.2.10, then an ERV must be included on that system unless one of the exceptions apply.

Hi Aru,

Yes you are correct - you have to create an exhaust air heat recovery with at least 50% effectiveness in your baseline bldg.  Check out section 6.5.6.1 of ASHRAE 90.1 for further guidance.

Hello there,

In a 5A climate zone, I am working with a Proposed model with a RTU (30,000 CFM, 100% OA) with exhaust air ER wheel in it. I am kinda sure that I've to create a ER wheel for the 90.1 Baseline (as per G3.1.2.10). Just want to make sure if I am correct? 

Help please. Thanks

Best,

Aru Sau
