[Equest-users] baseline model HVAC equipment placing

[Walson, Kristy]

Anura,

It depends on how large your building is and which version of ASHRAE  
you're using. For ASHRAE 90.1-2004, the baseline should have one  
system per thermal zone (even if you're proposed model is set up  
differently). If you're in ASHRAE 90.1-2007, up to a certain size  
building, it's still one system per thermal zone. After the threshold  
size, you're supposed to do one system for each floor of the building.  
I think the threshold size is 150,000 sq ft, but double check App.G to  
be sure.
