[Equest-users] app g economizer

[Bishop, Bill]

Aaron,
It doesn't seem ambiguous to me - air-side economizers are required in
the baseline for some system types and some climates. (The requirement
was expanded in 90.1-2007 vs. 2004. I haven't seen 2010 yet.) 
If it helps, "outdoor (outside) air" and "economizer, air" are defined
in Section 3.2.
Regarding architectural choices, I think one of the points of energy
codes is to influence design... ;)
Regards,
Bill

Subject: [Equest-users] app g economizer
 
A simple Q -  
 
Does everyone agree that the App G baseline building is supposed to have
an air-side economizer (in the mentioned climates)?
 
There are some buildings where architectural choices make it difficult
to accommodate an air-side economizer.
 
Nonetheless, Section G3.1.2.6 appears to require modeling specifically
an air-side economizer for the baseline
 
I am thinking it could be a bit ambiguous depending on what you think
"outdoor air economizer" means. 
 
Has anyone seen interpretations clarifying this one way or the other?
Or submitted a CIR to allow water-side economizers in the baseline where
that is the industry standard for the building type?
 
THANKS,
