New Certification Program for Window Attachments

CodeWatcher window attachment energy efficiency

A new certification program assesses the energy efficiency of blinds, shades, and storm windows. 

In 2018, the Attachments Energy Ratings Council (AERC) launched a DOE Building Technologies Office-funded rating and certification program for residential window attachments (interior and exterior blinds, shades, and storm windows) to provide consumers and utilities with credible, relevant, and comparable energy performance information.
