Building Envelope Innovation Prize - Secondary Glazing Systems

Pays cash prizes across three phases to teams that build cost-effective secondary glazing inserts upgrading commercial windows without a full replacement.

About 40% of U.S. commercial buildings still have single-pane windows, but only around 0.3% get a full window replacement each year because of the cost and disruption involved, even though modelling suggests high-performance windows could cut window-related heating and cooling energy use by nearly 25%. This prize targets that gap by rewarding secondary glazing inserts that fit over existing window…

Looks for window and glass manufacturers who can design cost-effective secondary glazing inserts that improve the energy performance of commercial buildings without replacing existing windows or altering a building's exterior. Solutions should cut heating and cooling energy use while costing and disrupting less than a full window replacement.
