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!
