Intent
To encourage reduced leakage of older refrigerants with high global warming potential (GWP) and ozone-depleting potential (ODP), and to encourage the installation of equipment using refrigerants with low GWP.
Requirements
Refrigerant Leakage Emissions Ratio
To calculate the refrigerant leakage emissions ratio, divide the total GWP of the refrigerants leaked during the 12-month reporting period by the total weight of all refrigerants present in the project.
Points are awarded according to Table 1.
Table 1. Refrigerant Leakage Emissions Ratio
Refrigerant Leakage Emissions Ratio | Points |
≤ 50 | 1 |
≤ 25 | 2 |
Projects that have neither refrigerant-using equipment in the project nor receive district thermal energy generated from refrigerant-using equipment automatically achieve the 2-point threshold.
Equation 1. Refrigerant leakage emissions ratio
where:
- i = Each refrigerant-using system in the project
- GWP = The global warming potential for the refrigerant used in each system
- Rc = Refrigerant charge, that is, the amount (pounds or kilograms) of refrigerant in the system at full charge

What does it cost?
Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.
