Inquiry

Energy and Atmosphere Credit 4 reads: "Install base building level HVAC and refrigeration equipment and fire suppression systems that do not contain HCFCs or Halons." Evaporative cooling complies with the intent of the credit. Our design uses an indirect/direct evaporative cooling system which uses no HCFC\'s or Halons. The evaporative cooling serves the entire building cooling needs including comfort cooling for the occupied areas as well as the telephone and data rooms. There is no halon system or special fire supression system. If the cooling is achieved without the use of refrigerants, other than water, and does not use compressor cooling, does evaporative cooling qualify to get this credit point?
