Thank you! There is another issue: The units (residential and commercial) will be delivered without AC, but the owners have the choice to install it or not. For this location (Costa Rica) typically it is 80% of commercial will do and 20% of residential. Will a lease agreement, establishing the allowed refrigerants comply with EAp3?

Roberto, it probably will comply - there's a good precedent for NC mixed-used projects that have unfinished commercial spaces that will be leased later and completed after certification has been finished. These are "core and shell" spaces that will have future "tenant improvements" (to use the US terms). If the lease agreements are very clear and enforceable regarding the refrigerants that will be allowed, I would imagine you could meet the requirements of EAp3. Since this is a pre-requisite, and failing to meet it will "kill" the certification effort, you may want to submit a CIR and confirm this. It's never been requested, but it might help if you can show any other similar buildings that are built or owned by the same team that do meet the EAp3 requirements to increase the reviewer's confidence that it is reasonable to expect these refrigerants will be selected.
