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?

Hi all, Is it possible to use the refrigerant R-1234 (HFO) to replace the R-134 in a centrifugal chiller? It has low GWP (around 4 or 5) and zero ODP, but it is not in the LEED online form nor in the BD&C guide. Do we have to do a CIR? Thanks in advance.

Use the data you have for the refrigerant, and list your source of information. I don't think you need a CIR.
