We have a problem with the interpretation of the information necessary to apply for this credit.

Our project has a WSHP bigger than 135000 btu/h. According to CPG table 2.9.2 the efficiency required for WSHP up to 135000 btu/h is 14 EER and the WSHP of our project has a 14.1 EER.

If all of my zone equipment and my chillers prescriptively comply with the Core Performance Requirements, but for HHW we have heat exchangers with purchased steam from a district source, then do I

Good day, we have a project that is naturally ventilated. ASHRAE 90.1 2007 states that the energy cost budget method cannot be used for designs with no mechanical systems.

I have a chilled beam system and am unsure which efficiency values to use from the options in the Core Performance Guide to show prescriptive compliance.

I'm working on a project that pursues the CI EAc1.3 credit by following Option 2 using ASHRAE 90.1-2007 Section 11.

We are trying to document the equipment efficiency for a fit-out we are involved in under Commercial Interiors 2009.

Hi, I am working on a CI 2009 fit out where the the landlord services such as heating pumps, boilers, AHU's and chillers are already installed.

Hi, Can somebody please send me the link to where I can get the "New Building Institute Advanced Buildings Core Performance Guide applicable for LEED CI 2009. Thanks.

AS part of the commercial interiors we are only specifying indoor HVAC plant items. The larger outdoor chillers, AHU's etc are landlord items and fall under the LEED C&S scheme.
