[BLDG-SIM] Zoning Granularity in Modeling

[Paul Riemer]

Thank you Kevin & Jeff for showing everyone the extreme range of
modeling approaches in our profession.  I happen to think the answer is
somewhere in the middle for most buildings types and analysis goals.  

Given the rise of LEED & EPACT, our industry needs more published best
practices addressing things like zoning granularity but before we can
write those we probably need to study them. 

Would anyone like to work together to find money and/or time to study
how sensitive energy and savings predictions are to zoning granularity
or other basic modeling practices?

Why do you need so many zones? Five per floor is the usual, two can also
suffice.

Ok, this could be embarrassing, but I got to know.

 

Could anyone shed some light on this error message I keep getting?  As
it turns out, I ended up with 405 zones.  I heard Doe-2.1 was limited to
99zones, is there a new limit for Doe 2.2. 

 

I was under the assumption that when modeling for LEED certification
each space in the architectural design should be modeled as a separate
space for building simulation, is this thought right or completely
wrong?  Thanks for the help.
