Having efficient new windows and doors doesn't mean giving up your house's historic character. These styles, seen at the International Builders' Show, will save money on the power bill without sacrificing curb appeal.
The biometric SmartScan lock opens when it recognizes a fingerprint—even if you've lost your keys, you've probably still got your hand. Its battery-powered system remembers up to 50 fingers, which you can save (or delete) in seconds. It's programmable for unlimited or temporary access, and, if necessary, you can just use an old-fashioned metal key.
Approx. $200; Kwikset.
