FAQs about EAc4 :

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?

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?

NC-2009 EAc4:Enhanced Refrigerant Management

Simultaneous Heating and Cooling

I have a project with an air-source heat pump that can either do heating, cooling or simultaneous heating and cooling. The heat pump has two refrigerant circuits. Can I count the heating tonnage against one of the refrigerant circuits and the cooling tonnage against the other? thanks,
