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

Equipment not list on CPG

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. Since the table doesn't list efficiencies for WSHPs bigger than 135000 btu/h, Do we comply with the credit requirement? Thanks in advance.

I think so. If the equipment you install is not covered by the standard then I think you comply by default.

Thanks Marcus. For the same project we have another doubt. In table 2.9.1 of CPG for unitary air conditioners and condensing units the required efficiency is expressed on EER and SEER. Can we comply with credit requirements achieving just EER or SEER, or are needed both?

Either one should work. The small equipment is usually rated in SEER, so not sure why they have both.

Thanks Marcus.
