How Window Treatments Can Lower Your Summer Electric Bill in Austin

Why windows matter so much

Sunlight that passes through glass turns into heat inside your home. The U.S. Department of Energy notes that much of the sunlight hitting a standard double-pane window enters and becomes heat. Blocking it at the window is one of the simplest ways to keep rooms cooler.

Stop heat outside first

The most effective approach is to block sun before it reaches the glass. Exterior shades and awnings on west and south walls stop heat outside, so it never enters the room.

Best interior options

• 3% solar shades: cut glare and heat while keeping the view.
• Cellular shades: honeycomb pockets add insulation at the window.
• Blackout shades and lined draperies: block direct sun completely in bedrooms and media rooms.
• Plantation shutters: seal against the frame and add a layer of insulation.

Timing is everything

Shades only help when they're closed during peak sun. Motorized shades on a schedule close automatically in the early afternoon, even when you're at work. See motorized shades and smart homes.

Where to start for the biggest impact

• West-facing living rooms and bedrooms first.
• South-facing windows second.
• Large glass doors and window walls.
• Upstairs rooms, which heat up fastest.
