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 , There is no mention of screw chillers either under the credit EA 4 or ASHRAE application. I can only see absorption, scroll and reciprocating. Can someone please help me with the life span to consider for screw chillers? As you know it has to be backed up by a source etc. Cheers, Mehdi

Hi Mehdi, If you have specific documentation on the equipment lifespan from the manufacturer, like a guarantee/warranty or service contract, then you should use that lifespan. If you don't have any information, you should use the default "other equipment" lifespan of 15 years.
