ENHANCED REFRIGERANT MANAGEMENT PERFORMANCE

EAc3

1–2 points

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

Achievement pathways	Points
Existing Buildings	1–2
Enhanced Refrigerant Management Performance	1–2

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 neither have refrigerant-using equipment in the project nor receive district thermal energy generated from refrigerant-using equipment automatically achieve the two-point threshold.
