A government-backed program that labels energy-efficient products, with guidance for choosing efficient windows.
ENERGY STAR is a program backed by the United States government that identifies energy-efficient products, including many windows. Its website offers guidance on choosing windows by climate zone and explains how window ratings relate to comfort and costs. Homeowners in Nashville often see its label on spec sheets and ask what it means for their own home.
We are an independent contractor, and we use program information as one input among several. We explain how the label, the window ratings and the climate zone fit together, compare models for your home and tell you plainly what a window can and cannot change. We also talk about air sealing, since leaks often matter as much as the glass.

Guidance differs by region, and Middle Tennessee has its own.
Labels help you compare products at a glance.
The label connects to U-factor and solar heat gain numbers.
Better windows can improve comfort and may help with bills.
Air leaks and insulation also matter.
We explain the numbers in everyday terms.
