EPA estimates that on a national average, ENERGY STAR certified (low-e) storm windows can save homeowners $350 on their annual heating and cooling bills (about 10%) when installed over single-pane clear glass windows (without existing storm windows). You can expect to pay back the incremental cost of the ENERGY STAR certified storm windows in about three (3) years.
Consumers who already have clear glass storm windows over their single pane windows and replace the storms with ENERGY STAR certified (low-e) storm windows can save an additional $50 per year on heating and cooling (about 2%) on a national average.
