[BLDG-SIM] LEED EA Prerequisite 1 and eQUEST

Peter,

 

You are correct in the interpretation of the ASHRAE rules and
regulations. 

 

However, for those working on a LEED project, the USGBC allows the
Appendix G analysis to suffice for the minimum energy performance
prerequisite. I was doing both (Appendix G and ECB) until I learned
about this allowance, which is stated in the LEED-NC Reference Guide
(Oct 2005) on page 164.  I guess you could produce a reduced energy use
building with Appendix G and not meet ECB; but to meet the LEED point
threshold (10.5%) it's still most likely you meet ECB.

 

Regards,

It is my understanding that what you state below is not actually
correct. demonstrating savings via Appendix G does not demonstrate
compliance with the standard. If you do not meet the mandatory
provisions you do not meet the prerequisite. If you do not meet the
prescriptive requirements then officially you need to demonstrate
compliance via the ECB method (chapter 11) in a pass/fail mode. 

 

provided you pass, then you use Appendix G to demonstrate savings.

 

all - correct me if I am wrong here.

 

Peter

Thanks to everyone for weighing in on this. It  turns out my question
regarding LEED was a little premature - you can use your Appendix G
documentation for this.

 

Which brings up the question - given that LEED now requires a minimum of
2 energy reduction credits to be earned, what's the point of the
prerequisite documentation?

Vik:

 

eQuest in its present form only can develop California Title 24 forms.
There IS a 90.1 Version in the works, but it is not yet available. Stay
tuned.

Vik,

 

I believe eQUEST will only produce overall performance for Title 24 not
the prescriptive forms.

Has anyone used eQUEST to document the EA prerequisite (compliance with
90.1 or other codes)? I suspect eQUEST does not do that for anything
other than Title 24 - am I correct?
