ENERGY STAR Window Requirements for Baltimore MD Homeowners

When Baltimore homeowners shop for replacement windows, ENERGY STAR comes up fast, but the label only tells part of the story.

How To Read Window Performance Labels Without Guesswork

You do not need to become a window engineer, but three ratings matter more than the rest: U-factor, solar heat gain coefficient, and air leakage.

U-factor is the insulation measure. The lower the number, the better the window usually holds heat in during winter and keeps cold surfaces from building up inside the room.

Solar heat gain coefficient, or SHGC, matters because Baltimore gets real summer sun. A lower SHGC can help reduce overheating on south- and west-facing walls, while slightly higher solar gain may still make sense in some shaded spots.

Air leakage is the detail that gets missed most often. A window may have good lab ratings and still feel drafty if the frame or installation is off.

Permits, Rebates, And The Details That Keep The Job Clean
