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?

CS-2009 EAc4:Enhanced Refrigerant Management

HVAC System

HVAC for the whole building is in the process of being designed (VRF system). We would like to know if the system can be installed in 2 stages, but we would like to submit the LEED certification after stage 1 is completed. Is this a valid approach for LEED CS 2009? Could this stepped approach in installing the HVAC System compromise the certification? • The first stage comprises all piping and HVAC preparations for the whole building, but HVAC equipment would be initially installed only in the areas to be occupied by the owner of the project. This would happen before full occupation and appropriate commissioning tests are conducted. • The second stage of the project is to install HVAC units on the tenants’ spaces as they occupy their rented areas.

Yolanda, your description seems consistent with how a typical CS HVAC system might be installed, and seems consistent with the credit requirements. You do need to require the use of certain systems in your tenant lease agreements to qualify for the credit, however.
