Hi. The credit language states that projects without cooling towers are ineligible for this credit. But if a project has cooling towers for the purpose of pre-cooling the refrigerant without utilizing water (only fan cooling), is the project still eligible for the credit? Kindly Emil Andersson

Emil, you seem to be describing an air cooled condenser - usually finned refrigerant coils with fans to circulate air over the coil. The unit condenses refrigerant gas to liquid. Since no water is used in the process, the project would ineligible for this water conservation credit. There is a form of condenser that uses a water spray over the refrigerant coil - an evaporative condenser. Although not strictly a "cooling tower" I would argue that there is justification for awarding WEc4.2 if the requirements are met.
