At the moment we are creating an energy model for a big warehouse, consisting of three floors.
In this warehouse, there are huge areas with cold stores for various consumable products. These stores are served by air cooled ammonia refrigeration equipment.

The question is:

For the Baseline model (it’ll be System 8), how to proceed with these cold stores. Should they be modeled identical to the Proposed model (project design), or it should follow the rules for System 8 – meaning a system per each floor.

Your suggestion is highly appreciated.
