I have an O+M project considering Option 2. The reference guide states that Retail projects must meet Option 1 or 2 for all HVAC systems and stores with commercial refrigeration systems must comply with stated additional requirements. My question is, if a project is not pursuing LEED O+M Retail but has commercial refrigeration systems do they also have to comply with the stated additional requirements?
- Average HFC refrigerant is no more than 1.75 lb. of refrigerant per 1,000 BTU/h (2.72 g of refrigerant per kW) total evaporator cooling load.
- Project-wide annual refrigerant emissions rate is no more than 15%.
- Project uses only non-ozone-depleting refrigerants.

LEED v4.1 OM guide says that there has been no changes from LEED v4 in this credit. Hence, as the v4 manual states, the commercial refrigeration systems must comply with these addtional requirements in non-Retail projects by following the prescriptive criteria available to retail projects for commercial refrigeration systems. Both these prescriptive criteria for the commercial refrigeration systems, and the credit requirements for the HVAC refrigerant-using systems must be met to achieve credit compliance in this case.
