This document describes an energy efficiency program in Vermont that achieved significant energy savings and market transformation by working directly with HVAC equipment suppliers rather than end users. The program collaborated with distributors, manufacturers and contractors to develop strategic plans to increase sales, marketing, inventory and training of efficient products. As a result, sales of efficient circulator pumps increased 600-10,500%, and sales of heat pumps grew 43.8%. The program showed suppliers how promoting efficient equipment could increase their profits through higher margins and inventory turns. This upstream approach was more effective at transforming markets than conventional downstream rebates.
