Understanding ENERGY STAR Window Requirements for Baltimore, MD Homes

How ENERGY STAR Fits Baltimore's Weather And Housing Stock

Baltimore weather is hard on glass and framing alike. Hot, humid summers, cold snaps, and a lot of older housing stock mean windows have to do more than look good from the street.

What To Look For Beyond The Sticker

A better U-factor is especially useful in older homes where the window opening, not just the glass, is part of the comfort problem.

SHGC takes a little more judgment. A lower SHGC blocks more solar heat, which can help on western and southern exposures, while a slightly higher number may make sense where you want passive sun in the colder months.
