Extracted Content
- For equipment without automatic leak detection systems, this means checking pressure loss and leaks at least as frequently and with the minimum intervals for equipment containing refrigerants as follows, with a total GWP as follows:
o Every 24 months for 50 tCO2e or less
o Every 12 months for 50 to 500 tCO2e
o Every 3 months for more than 500 tCO2e
-
Identifying the maximum time frame for repairing leaks.
-
More frequent leakage testing and repairing, to be twice as frequent if the total annual refrigerant recharge/leakage exceeds 1%.
Retail (1–2 points)
- Meet Option 1 and/or Option 2 above, or Option 3 below, for a maximum of two points.
AND/OR
Option 3. GreenChill Certification for Food Retailers (1–2 points)
Available to projects where food retailing constitutes more than 20% of the project’s gross area.

For all options DISTRICT ENERGY
Projects with district energy must comply with the requirements of this credit at the district facility or see additional guidance for interpretation of credit requirements.
REQUIREMENTS EXPLAINED
The credit builds on the EAp5: Fundamental Refrigerant Management requirements and rewards teams who further minimize or eliminate refrigerant impacts for their projects. Refrigerants used in equipment that provides thermal comfort, SWH, process heating or cooling, or refrigeration for food storage or other process application in buildings are powerful GHGs, typically causing over a thousand times the detrimental impact of carbon dioxide. As projects electrify heating and SWH systems with heat pumps, mitigation of refrigerant impact becomes increasingly important.
