Energy Savings from New Windows in Baltimore Climate Zone 4A

How Baltimore Weather Exposes Weak Windows

Baltimore's 4A climate puts windows through a practical test all year, with muggy summer air, winter heat loss, and plenty of temperature swings in between.

• HVAC runtime often drops because the house holds temperature better.
• Interior comfort tends to feel more even, especially near exterior walls.

Orientation also matters, since south-facing rooms can gain useful winter sun, while west-facing rooms may overheat in the afternoon.

If you are comparing upgrades, energy efficient windows are best judged as part of the whole house, not as a magic fix on their own.
