                       GreenChill Store Certification Criteria
 The following document summarizes the criteria required for achieving both Gold- and Silver-Level
 Certification. Please see the GreenChill Store Certification Program Guidance for more information on each
 of these criteria.

 Gold-Level Store Certification: To qualify for GreenChill's Gold-Level Store Certification, a store must
 meet the requirements under either A or B:

   A.  HFC-Based Refrigeration Systems

        •   The store must only use refrigerants with zero ozone-depleting potential;
        •   The store must only use refrigerants that have been found acceptable by EPA's Significant New
           Alternatives Policy Program (SNAP) for use in retail food refrigeration end-uses;
        •   The store must achieve an average HFC refrigerant charge equal to or less than 1.25 Ibs. of
           refrigerant per 1000 BTU/hr. total evaporator cooling load;
        •   The store must achieve a store-wide annual refrigerant emissions rate of 15% or less; and
        •   All newly constructed stores must be leak tested at installation according to the standards in
           GreenChill's Installation Leak Tightness Testing Guidelines


   B.  Refrigeration Systems using Low-GWP Refrigerants

        •   The store must only use refrigerants with zero ozone-depleting potential;
        •   The store must only use refrigerants that have been found acceptable by EPA's Significant New
           Alternatives Policy Program (SNAP) for use in retail food refrigeration end-uses; and
        •   All refrigerants used in the store must have global warming potentials (GWP) lower than 150.

 Silver-Level Store Certification: To qualify for GreenChill's Silver-Level Store Certification, a store
 must meet the following requirements:

      •   The store must only use refrigerants with zero ozone-depleting potential;
      •   The store must only use refrigerants that have been found acceptable by EPA's Significant New
         Alternatives Policy Program (SNAP) for use in  retail food refrigeration end-uses;
      •   The store must achieve an average HFC refrigerant charge equal to or less than 1.75 Ibs of refrigerant
         per 1000 BTU/hr. total evaporator cooling load; and
      •   The store must achieve a store-wide annual refrigerant emissions rate of 15% or less.
