The Efficient Windows Collaborative (EWC) aims to increase the market penetration of energy-efficient window products in both the residential and commercial sectors. The EWC promotes energy performance rating and labeling among window manufacturers. Furthermore, the program educates builders, designers, and consumers about the benefits of energy-efficient windows and how to select efficient windows for various climates. The EWC supports the development of a market for emerging window technologies by providing information about their energy savings potential.
