FAQs about EAc4 :

We plan on pursuing this credit only if we need to do so to meet our certification target, i.e. if another credit we are counting on gets rejected. How late can we apply for this credit?

I'm working on a renovation project and we'll be keeping some of the existing equipment. Shoud we include these systems in our calculations?

Which portions of a VRF/VRV system should be considered for this credit?


For a split system, does the cooling capacity refer to the cooling power of the interior device (evaporator) or of the outdoor unit (condenser)?

What is the required timeline for completing a CFC phase-out for EAc4?

How can I document a longer equipment life (20 or 30 years) than what is listed in the LEED Reference Guide?

Do the requirements apply to portable fire extinguishers or only permanently installed building-wide fire suppression systems?

NC-2009 EAc4:Enhanced Refrigerant Management

Multiple small split systems - Can they ever work?

I have about sixty-five split systems in two apartment buildings using R-410a. The factor that is keeping me from meeting this credit's requirements seems to be Rc (lb/ton). Since these are small systems, their Rc runs from 1.9 to 3.5, but most are about 2.8. It looks like that makes compliance impossible. Has anybody, anywhere, ever made this credit with small split systems? Or am I just done for?

You will probably not earn the credit with split systems. Hopefully your system selection is helping you save energy and earn points under the energy performance credit.
