Would we need to consider the refrigerants used for a split unit which is dedicated specifically for the cooling of a fume cupboard in a laboratory building?

Hi, We are working in a project that will have kitchen refrigerators, some of this equipment has refrigerant R-438A. I believe that this refrigerant complies with the prerequisite, since it is a HF

Has anyone ever documented this prereq. with a system using R407F? It's not part of the drop down list on the form and we're not sure it will comply. Thanks in advance for your help!

We are working on a full service hotel project. For the commercial kitchen, it is my understanding that the permanent walk-in cooler and freezer units should be included in the credit.

I would like to know if the following complies with EAp3: We have a new construction (in process 2011) and the owner is purchasing an old HVAC systems that used R-12.
