Save Money and Energy — Choose ENERGY STAR Qualified Windows, Doors, and Skylights

Installing ENERGY STAR qualified windows lowers energy bills and saves you money over single-pane and even new double-paned, clear-glass windows.

For a typical home, choose ENERGY STAR and save:

  • $126–$465 a year when replacing single-pane windows
  • $27–$111 a year over double-pane, clear glass replacement windows
