ENERGY STAR Window Requirements for Baltimore MD Homeowners

If you are replacing windows in Baltimore, ENERGY STAR is usually the first label people ask about, but the label alone does not guarantee the right result for an older house.

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.

Air leakage is the quiet troublemaker. A window can look efficient on paper and still feel drafty if the frame, sash, or installation is sloppy.

In older Baltimore houses, especially brick rowhomes, fit and installation can matter as much as the performance label. A high-rated window in a bad opening is still a bad result.

Why Baltimore Housing Stock Changes The Equation
