Project teams often confuse CFCs and HCFCs. Chlorofluorocarbons (CFCs) have been completely phased out of new equipment in the U.S. as of 1996, and hydrochlorofluorocarbons (HCFCs), their transitional substitutes, are being phased out as of 2010. EAp3: Fundamental Refrigerant Management, addresses only CFC use in base building equipment, whereas this credit deals with all refrigerants, including CFCs and HCFCs. Hydrofluorocarbons (HFCs) are another class of refrigerants that are used as more environmentally friendly substitutes for CFCs and HCFCs. Currently, there are no federal regulations to phase out the production of HFCs.
