Interior designers: Many ways to cut energy costs

When decorating our homes, we tend to consider things like beauty and comfort, the durability of pieces we might buy or the image they project. But how many of us stop to consider our energy bills?

Energy-smart design goes way beyond choosing Energy Star-rated appliances or switching to compact fluorescent bulbs, although both are good ideas. Today's experts see opportunities to conserve energy in nearly every aspect of home design.

There are "so many things that look gorgeous and totally save you money," says interior designer Brian Patrick Flynn.

We asked Flynn and fellow designers Mallory Mathison and Janine Carendi to share their energy-wise secrets:

WINDOWS

Add a layer of heavy "blackout" lining to the back of draperies (DIY or hire a seamstress), Flynn says. "It makes the drapes hang better, and gives them a richer, more full look," he says. The barrier helps keep out noise pollution, as well as light in summer and cold in winter, he says.

As you do with clothing, insulate with layers: Mathison suggests layered window treatments "with a wool sheer and then an outer panel" of heavier fabric.

Check all windows for drafts, Carendi says, and plug holes, or consider replacing windows or repairing window frames. "You would be shocked how much heat you lose," she says, from windows that aren't properly sealed or insulated.

All three designers recommend UV-protectant film, made by 3M to keep heat out in summer and protect furniture from fading (bonus: some versions also enhance security).

LIGHTING/ELECTRONICS

Swapping out bulbs is a great energy-saving first step. The earliest generations of compact fluorescent bulbs gave off a harsh light that turned off some consumers, but newer versions offer softer, more appealing light.

Next, Carendi recommends replacing old dimmers with energy-smart models (she likes Lutron).

The designers also suggest using power strips or other devices that make it simpler to switch off electronics at night. Eliminating energy usage from items you don't use overnight can provide real savings.
