This prerequisite focuses on the elimination of CFC-based refrigerants that contribute to ozone depletion in HVAC&R equipment.

The credit covers all space-conditioning and refrigeration systems included in the LEED scope of work, including chillers; unitary HVAC equipment (split and packaged); room and window air-conditioners; computer, data center, and telecom room-cooling units; commercial refrigeration equipment; and fire suppression systems. The prerequisite does not, however, apply to small units and other types of equipment, such as refrigerators and small water coolers that contain less than 0.5 pounds of refrigerant.
