ENERGY STAR Window Requirements for Baltimore MD Homes

How ENERGY STAR Applies To Windows In Baltimore MD

If you are comparing replacement windows in Baltimore MD, the ENERGY STAR mark is a useful shorthand for performance, especially when you live with hot July sun, windy winter days, and older houses that leak air at every seam.

ENERGY STAR is not a brand of window, it is a standard that tells you the product has met specific efficiency targets for your climate zone.

For Baltimore homes, that usually means paying attention to two ratings: U-factor and solar heat gain coefficient, or SHGC.

The right balance depends on the orientation of the house, the amount of shade, and whether the room tends to overheat in summer or feel cold in winter.

An experienced window replacement company can confirm the cause with a quick inspection.
