[Bldg-sim] Building zones

[John Aulbach]

Genai:
 
I don't do much LEED. But don't you set up the model in the way it is actually zoned? A single zoom would not have two thermostts.

Dear all, 

I often do  loads, and I have not had this question before. Now I have a debate with my co-worker. 
The LEED and ASHRAE 90.1 say that every solar exposure has to have a separate control zone. I agree. But ...
I usually model a room with different exposures as one zone if it is different from other rooms or attach this room  to a zone with the exposure that has more influence ( if room has South and West walls, I attach to a zone with similar usage rooms with south exposure). And my co-worker says that LEED asks to submit a plan with properly modeled zones which have to have their own control. 
The question is 
Do I have to assume 2 zones for a room with 2 different exposures or I still can model as one zone with one control. 

Thank you,

With best wishes,
