Room Air Conditioners: ENERGY STAR Most Efficient Influence Evaluation and Baseline Assumptions Review

The Northwest Energy Efficiency Alliance (NEEA) contracted with TRC Engineers, Inc. to review NEEA’s influence on the ENERGY STAR® Most Efficient (ESME) specification development for room air conditioners (room ACs), along with NEEA’s naturally occurring baseline market share assumptions for room ACs.

In September through December 2021, TRC conducted qualitative and quantitative analyses to address the research objectives. The report showed that NEEA played a supporting role in the development of the ESME specification for room ACs. Further, the report provides input on what the baseline market share growth for room ACs would be in the absence of the ESME specification.
