The Consortium for Energy Efficiency has revised its High Efficiency Commercial Air Conditioning and Heat Pump Initiative.

Additions include specifications for variable refrigerant flow and new criteria based on an integrated energy-efficiency ratio.

The initiative, which includes a high-efficiency energy-performance specification for commercial air-conditioning and heat pump equipment, was created to support CEE members who are program administrators of energy efficiency programs.

By incorporating criteria based on the ratio and adding specifications for high-efficiency variable-refrigerant flow multi-split air conditioners and heat pumps, CEE officials report that the initiative provides efficiency-program administrators with an improved basis for claiming savings across the full range of equipment operation.

“The significance of the IEER measurement is that program administrators can promote greater energy as well as peak savings,” explained Marc Hoffman, acting deputy director of CEE.

While the goal is primarily to meet efficiency program administrator needs for energy savings, the consortium said it believes this goal could not have been achieved without the help of the HVAC industry.

“We are pleased to contribute to the process of updating this important specification,” said Stephen Yurek, president and CEO of the Air-Conditioning, Heating, and Refrigeration Institute. “This project, and many like it, is representative of what we can do when we work together toward a common goal.”

This is the first update to the specification since 2009, and includes current energy savings potential, equipment trends, and a unitary HVAC market analysis, along with descriptions of market barriers to efficiency.
