The intent of this prerequisite is to reduce ozone depletion by reducing or eliminating the use of Chlorofluorocarbons (CFCs).

Requirements for Certification:

Do not use CFC-based refrigerants in new base building HVAC&R systems.

For existing base building HVAC equipment, complete a CFC "phase-out" prior to project completion.

Successful Strategies:

• Replace CFC-based refrigerant.
• Consider non-refrigerant based cooling such as evaporative cooling in dryer climates.

Helpful Hints:

1. This credit has relevance to EAc4, Ozone Protection, so be aware of both when specifying HVAC equipment.

Historical Data (updated June 2006):

• Fundamental Refrigerant Management is a prerequisite for LEED Certification and must be met.
