Table 1. Refrigerant GWP Benchmarks
| GWP benchmark* | Equipment and systems |
|---|---|
| 1400 | Heat pump service hot water heaters |
| 700 | HVAC |
| 700 | Data centers, computer room air-conditioning, and information technology equipment cooling |
| 700 | Process chiller equipment or ice rink refrigeration equipment |
| 300 | All other process refrigeration for retail, industrial, or cold storage |
*GWP benchmarks are based on a 100-year time horizon GWP relative to CO2.
AND/OR
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 protocols for:
o Updating the refrigerant inventory.
o Tracking and recording refrigerant charge and leakage rates for all refrigerant-using
equipment.
