[Equest-users] Modeling a non-existing cooling system

[Daniel Knapp]

Hi Jeff,

Look at ASHRAE 90.1-2010 systems 9 and 10 which are heating only.  They also show up in addenda dn, do, dp, dq, dr to 90.1-2007.  

Best wishes,
Dan

I completely understand the logic of this requirement – in most cases.

This space is almost half of the building area, will not be cooled, has large overhead doors that are mostly open, and is a place where diesel engines run.

The model will be submitted for LEED review. I can certainly model a cooling system but it does not seem to make sense in this case.
