LEED BD+C: New Construction | v3 - LEED 2009

Fundamental refrigerant management

EAp3 | Required


To reduce stratospheric ozone depletion.


Zero use of chlorofluorocarbon (CFC)-based refrigerants in new base building heating, ventilating, air conditioning and refrigeration (HVAC&R) systems. When reusing existing base building HVAC equipment, complete a comprehensive CFC phase-out conversion prior to project completion. Phase-out plans extending beyond the project completion date will be considered on their merits.

Existing small HVAC units (defined as containing less than 0.5 pounds (228 grams) of refrigerant) and other equipment, such as standard refrigerators, small water coolers and any other equipment that contains less than 0.5 pounds (228 grams) of refrigerant, are not considered part of the base building system and are not subject to the requirements of this prerequisite.

Credit substitution available
