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

leed credit EAc4

Having built a cafeteria at a local University we are having trouble getting the Q (tons ) for some of the refrigerated display equipment. Has anybody had luck getting this information for True Mfg. Models TSSU-48-12, TSSU-60-10, TPP 44, TAC 48, G4SM-23PT. We have contacted the MFG.s engineering dept and they have indicated they do not have this info. We do have the refrigerant charge on some of this equipment but need the tons to calc the total. Thanks any help greatly appreciated

Hi Craig, Thanks for the information. Will you also have the refrigerant mass and cooling capacity for the True Mfg. model T-24-GC-S? We got the refrigerant which is R404A but we are having difficulty getting the rest of the information we need to get the Rc. Thanks!
