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?

Nena, Can you get the cooling capacity (in tons) and the total pounds of refrigerant in a full charge (lbs of refrigerant) for the equipment from manufacturer cut sheets, technical information documentation, or the company website? Refrigerant charge is calculated by dividing the total pounds of refrigerant in a full charge by the cooling capacity of the equipment. So the resulting value is in units of lbs/ton.

Is the original charge in manufacturer's spec the same as full charge? I can only find the original charge.

The cooling capacity of the split units in our project is calculated according to ISO not ARI standard. Can I use it ?
