The Window Selection Tool and Products Database
The EWC web site's Window Selection Tool is a web-based database that links consumers to qualified energy efficient window products. Here's how it works: Consumers visit the EWC web site to learn more about energy efficient products. After finding their state under the Window Selection Tool, consumers compare the energy performance of over 30 generic window product types. Once they identify the right generic product type for their needs, they can click through to a list of qualified energy efficient products for that given product type.
