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.

With best wishes,
Genia Gorbachinsky
