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

CPG - Efficiency Compliance

Hello, I would like to know on how to comply CI EAc1.3 if using base build Chilled Water Fan Coil Units. What is the alternative to verify the efficiency compliance on Core Performance Guide if the chiller's efficiency is not available.

If the chiller's efficiency in not listed in Table 2.9.5 see note b in that table and then see the link at the bottom of the page for more chiller tables. http://www.advancedbuildings.net/reference-materials/reference-materials-access-form

Thanks Marcus but how about Chilled Water Fan Coil Equipment Efficiencies since these are not covered under Core Performance Guide? Do we really need to collate the Landlord / Base Build systems together with the project's HVAC systems to comply with this credit requirement? Thanks in advance.

Chilled water fan coil units do not really have a rated efficiency. It is the efficiency of the chiller itself that is in CPG 2.9. Yes it appears that way. The whole system design is what is addressed by sections 1.4 and 2.9.
