Additional Guidance

GSA's Green Proving Groundopens in new window recommends use of this product across all climate zones. Biggest efficiency gain and fastest payback will be in buildings with either single glazing or existing applied film that is low performing or nearing the end of its (~15 year) service life. Also consider this item for lower-performing double glazing that does not already have a low-e coating between panes.
