U-factor tells you how much heat passes through the window assembly. The lower the number, the better the window holds back heat transfer.

SHGC, or solar heat gain coefficient, measures how much solar heat gets through the glass. In a hot climate, lower is usually better for sun-facing windows.

Energy Star ratings give you a baseline, but the best fit still depends on which side of the house the window faces, how much shade the lot has, and whether the home is a newer build or an older structure with different framing conditions.
