[Equest-users] LEED Simulations

[Sami, Vikram]

Just to add to what Nick said - the rating authority s now the GBCI (green building certification institute). The percentage is based on energy cost and not energy usage - so you might benefit from peak shavings in a TOU rate.

The rating authority for a LEED project is, essentially, USGBC - but USGBC has more or less defined (if loosely) what is required for documentation through the LEED EAc1 template/Handbook.  You might do better to keep section G1.4 in the back of your mind and instead refer primarily to the current EAc1 template and associated Handbook chapter.

LEED EAc1 credits, using the first compliance (energy simulation) method, are based on annual costs - not consumptions.  I think that syncs with 90.1's current glossary terms for performance...

If attempting to show percent improvement for LEED credit per ASHRAE 90.1-2007 Appendix G, who is the "rating authority" in section G1.4?  USGBC?  There will be similar documentation submitted to USGBC I know, but is there some piece of information I am missing?  Does ASHRAE "rate" building performance based on eQuest results?

Also, second question, is percent improvement based on energy usage, or cost of energy usage with regards to LEED?

Thanks!
Tim
