Hello I am leading a LEED Certification for a Supermarket.

My client is a supermarket that leases the supermarket land for 20 year or more, and in there they will construct their stand alone supermarket.
They are about to rebuild a store and they have the complete control over the entire building´s envelope.

The thing is that they have one company that owns the infrastructure and another that operates the infrastructure, that´s why they are asking me which Certification type adequate for us.. New Construction Retail or Commercial Interiors Retail.

The other thing to mention is that after the summer season is over, they close the supermarket for 6 months and when they reopen they change some of the interior equipments as ovens, cash machines, refrigerators, etc.

Which one would be more appropriate and why?

Thanks!
