[Equest-users] eQuest for Energy Code Compliance? (Whole Building Performance path)

[Dahlstrom, Aaron]

Steve:

I have used eQUEST and another DOE-2 interface (VisualDOE) for a dozen or so energy code compliance models.

I don't use the compliance shell, but rather create my two buildings (design and baseline) according to the rules in section 11 of ASHRAE 90.1-2007.

I recently looked at IECC 2009 section 506 and saw a provision requiring that the baseline model be automatically generated by the software. I believe it specifically prohibits any user intervention in creating the baseline. Seeing this, I believe that eQUEST and VisualDOE have not implemented compliance shells that achieve that level of perfection - so I chose to use IECC section 501.1 / 501.2 to use ASHRAE 90.1's ECB (section 11) instead.

Hello eQuesters

I was wondering if any of you had used eQuest for Energy Code compliance outside of California?  e.g. 90.1-2010 chapter 11 or  IECC-2009 section 506? (the whole building performance methods).
If yes, specifics?  If not, what software do you use for this instead?

By 'whole building performance' I mean a shortcoming in one category (e.g. too much glass, too many lights) can be compensated for from another category (e.g. efficient HVAC).


What I have learned so far:
COMcheck works fine for prescriptive compliance which is the way most commercial plans are sent through.   COMcheck is not set up for whole building performance ( I have tested this).
eQuest works well for LEED EA credits which uses 90.1 Appendix G.....
Appendix G starts out by saying it is not intended as an alternative for chapter 11....


thanks folks
Steve
