CEE Commercial Unitary Air-conditioning and Heat Pumps Specification

Date Published


In support of the High Efficiency Commercial Air Conditioning and Heat Pump Initiative, CEE publishes the CEE Commercial Unitary AC and HP Specification, which provides high efficiency performance specifications for the following types of equipment:

  • air-, water, and evaporatively-cooled unitary air conditioners;
  • air- and water-source unitary heat pumps;
  • air cooled variable refrigerant flow multisplit air conditioners; and
  • air- and water-source variable refrigerant flow multisplit heat pumps

The Specification provides consensus definitions of efficient performance for use as a basis for CEE member's commercial air conditioning and heat pump programs. By harmonizing programs around a common performance specification, CEE members collectively create a strong market pull to increase the availability of efficient equipment in US and Canadian markets.

Note on 2018 Federal Minimums and Initiative Enhancements

Greater market availability of energy efficient equipment enabled new US federal minimum energy conservation standards (federal minimums) for unitary air-conditioning (AC) and heat pump (HP) equipment ≥65,000 Btu/h and <760,000 Btu/h that took effect January 1, 2018. In addition, the US Environmental Protection Agency (EPA) recently updated the ENERGY STAR® Light Commercial HVAC Specification, which also took effect January 1, 2018. In light of these market developments, on May 30, 2018 the CEE Board of Directors approved enhancements to the HECAC Initiative to ensure the continued market relevance and role of the Initiative. Note that 2018 initiative participation is based on the Appendix A specification; starting on January 1, 2019, Initiative participation will be based on the Appendix B specification.
