Consortium for Energy Efficiency

CEE, a nonprofit public benefits corporation, develops national initiatives to promote the manufacture and purchase of energy-efficient products and services. Its goal is to induce lasting structural and behavioral changes in the marketplace, resulting in the increased adoption of energy-efficient technologies.

The CEE Directory provides easy access to energy efficient residential and small commercial central air-conditioners and heat pump equipment, gas water heaters, furnaces and boilers certified through AHRI. The directory lists thousands of certified systems that qualify for CEE’s residential and commercial HVAC and water heating initiatives.
