Eligible equipment and rebate amounts
Replacement windows
Improve the efficiency of your business by installing high performance windows that can significantly reduce energy bills without sacrificing style, versatility or comfort.
Efficient windows can help reduce your energy bills up to 15 percent. Over the lifetime of a typical window, the return on investment can be substantial; and as an added benefit, saving energy prevents pollution. Double-paned windows are, on average, twice as efficient as the average window manufactured 10 years ago.

| Windows with a U-factor of 0.30 or less (minimum size of eight square feet each; one opening equals one window) |
