The PNC SmartHome is complete at the Cleveland Museum of Natural History and open to visitors who want to learn how to make environmentally-friendly improvements to their own properties. The 2,500-square-foot three-bedroom house uses 90 percent less energy than a traditional home, and it uses no furnace for heating and cooling. The walls are a foot thick and packed with insulation, while the windows are triple-pane glass -- both of which reduce heat loss. The home is heated and cooled with small heat pumps.

"The museum wanted to help people understand how they can dramatically reduce energy consumption," says David Beach, director of the GreenCityBlueLake Institute at CMNH. "We think the SmartHome will be the first home to receive passive home certification in Northeast Ohio."

Other features include hardwood floors made from 100-year-old reclaimed wood and artwork with environmental themes created by local artists. The landscaping features storm water management techniques to keep rain water on-site instead of in storm sewers.

So far, the home has been well-received. "People walk in it and go, 'wow,'" says Beach. "What they are reacting to immediately is what a beautiful home it is. Then they see they can learn things [to do] for their own homes."

The house will be moved to an empty lot on Wade Park Boulevard this fall and will go on the market soon. Beach says they've already received inquiries about purchasing the house.

Tours run Monday through Saturday 11 a.m. to 4 p.m., Wednesdays from 11 a.m. to 9 p.m. and Sundays 12:30 p.m. to 4 p.m. Tickets are $5 with museum admission, $3 for those who can't go upstairs. Children 2 and under are free.
