Glazing Retrofit Coating
Preliminary Technology Assessment
What is This Technology?
This clear, water-based spray-on window coating molecularly bonds to existing windows surfaces, and is designed to reduce heat gains across the entire solar spectrum without significantly reducing transmittance of visible light. It is intended for use in retrofits where existing windows do not have coatings or have coatings that need to be replaced.
Why is GSA Interested?
The glazing retrofit coating can be used in any climate. It is projected to be most effective in hot climates where solar heat gain is a larger issue, where it can reduce cooling loads.
Adapted from a report by the National Renewable Energy Laboratory. The Green Proving Ground program, in association with a federal laboratory, is subjecting the glazing retrofit coating to real-world measurement and verification in GSA buildings. Findings from that investigation will be available in late 2013 or early 2014.
