Consortium for Energy Efficiency (CEE) High Efficiency Commercial Air Conditioning and Heat Pump (HECAC) Initiative

Date Published

January 12, 2016


The goal of the CEE HECAC Initiative is to increase the availability of high efficiency commercial unitary air conditioners (AC) and heat pumps (HP) across the United States and Canadian market and to encourage efficient upgrades to commercial AC and HP systems. The primary strategy used to meet the Initiative objective is to maintain and support common performance specifications for high efficiency AC and HP equipment, which administrators of voluntary energy efficiency programs can promote in their local markets. The Initiative document outlines the initiative goals, approach and strategies. It also provides a market and technology overview, barriers and opportunities, efficiency specifications, and initiative participation requirements.


A minor correction was made to the Specification on February 17, 2016. The correct tier 1 HSPF requirement for single packge heat pumps less than 65,000 Btu/h is 8.2 HSPF or higher. 

The following corrections and clarifications were made on March 14, 2016.

  • A description of the range of energy savings offered by an air conditioner meeting the CEE advanced tier was added to the second paragraph under section 5.5.2 Unit Savings Potential.
  • The words "Product Availability" were removed from the title of Table 2.
  • The words "Product Availability"  were removed from the title of Table 4 and product availability data was removed from the table.
  • The words "Product Availability" were removed from from the title of Table 5.

Note on 2018 Federal Minimums

New US federal minimum energy conservation standards (federal minimums) for unitary air-conditioning and heat pump equipment ≥65,000 Btu/h and <760,000 Btu/h took effect January 1, 2018. The Commercial Air-conditioning and Heat Pumps Committee is considering revisions to the High Efficiency Commercial Air-conditining and Heat Pumps Initiative that ensure its continued market relevance and role. The Committee has agreed on a proposal to revise the CEE Commercial Unitary AC and HP Specification. CEE distributed the revision proposal to industry partners for a sixty-day review period on November 17 with a comment deadline of January 26, 2018. Following the completion of the industry review period, CEE staff will convene the Committee to consider the full slate of industry comments and determine if modifications need to be made, and if additional industry review would be necessary or beneficial. While subject to Board approval, revisions to CEE commercial unitary equipment specifications are anticipated during the first quarter of 2018 to take effect prior to the 2018 cooling season.
