FAQs about EAc1.3 :

If pursuing Option 2, what is the scope of the energy model if the space shares a central plant, and what type of software should be used?

For Option 1, Zoning and Controls, is a thermostat considered an “active control capable of sensing space demand"?

CI-2009 EAc1.3:Optimize Energy Performance—HVAC

CIv2009: Advanced Buildings Core Performance Guide (CPG)

Hi Everyone, We have two different versions of the CPG! One with " Printed Date: July 2007" and one "Revised Edition 1.11, July 2011" that have completely different required efficiencies for mechanical systems. The reference guide, LEEDonline forms or the CIRs fail to address that. Which one should we use to meet the intent of EAc1.3 Option 1? Thanks,

We have always used the July 2007 version. I haven't seen an addendum or interpretation from USGBC about an update.

Yep the one in effect when LEED 2009 came out is the one you must use. However if you used to more recent one it would likely be approved.

Thank you Marcus and Erik. We'll do just that. Since there is no specific guidance on the versions, I'll assume the older one will work just fine. Thanks again.

http://www.powells.com/biblio/9780974296913?page=customercomments#product_details Is this the book you are referring to? I need to buy this and want to make sure it is only available to purchase and wasn't available online to view somewhere.
