Option 2. Limit Refrigerant Leakage (1 point)

Core and Shell only This option is only applicable to projects with at least 20% of total estimated heating and cooling generation capacity in the project scope of work.

Design, construct, and operate the project’s refrigerant-using equipment to minimize refrigerant leakage.

DESIGN

  • Refrigerant-using equipment shall be self-contained, with no field-installed piping:

o For equipment with refrigerants > 700 GWP, AND

o For at least 80% of the total GWP of refrigerants used in the project

  • Specify an automatic leak detection system in fully enclosed spaces with equipment that has an overall refrigerant charge exceeding 100 tCO2e.

INSTALLATION

  • Field-installed refrigerant piping shall use brazed or press-type fittings.

OPERATION

  • Have in place a refrigerant maintenance plan and designate a responsible oversight party. The plan shall include standards for recordkeeping and the following protocols:

o Updating the refrigerant inventory.

o Tracking and recording refrigerant charge and leakage rates for all refrigerant-using

equipment.
