ENERGY STAR Window Requirements for Baltimore MD Homes

What ENERGY STAR Really Means For A Baltimore Window Upgrade

In Baltimore, the ENERGY STAR label matters because it points to windows that are designed for real weather, not just a showroom display.

The label is tied to performance criteria that vary by climate zone, and Baltimore sits in climate zone 4A, so the target numbers are set with this region in mind.

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

A lower U-factor generally means better insulation, which is helpful in older rowhomes and colonials where heat loss through windows can be easy to feel on a windy night.

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