Q: What is required of a window to receive tax incentives for efficiency?

That is an excellent question and very timely. The tax incentive qualifications have changed significantly over the years, and will likely continue to adjust to market demands and new policies. Case in point, the economic stimulus package, H.R. 1: Div. B, Sec. 1121 (The American Recovery and Reinvestment Act of 2009), which was recently accepted by Congress and signed by President Obama, included a few significant changes to the standards for windows, doors and skylights that qualify for federal tax credits.

Exterior window and door assemblies are tested for their performance characteristics and carry a National Fenestration Rating Council (NFRC) label that displays their measured U-value (insulating) and their SHGC (solar heat gain coefficient) value. The U-value indicates how conductive the windows are to thermal energy transfer.
