The university's compact Enable home is one of the entries in the U.S. Department of Energy Solar Decathlon design competition in Denver in early October. The two-bedroom, 1,000-square-foot dwelling uses rooftop solar panels to produce enough electricity to power the house and charge a high-efficiency heat and air-conditioning system and an electric car in the garage. The technology also includes self-cleaning windows and walls treated to break down indoor pollution.
The design team spent more than a year talking with and observing boomers in the community to get a firsthand sense of what features might appeal to them, said Maggie Waldron, director of program operations for the House by Northwestern team.
As a result, the single-story house offers features that include doorways without thresholds, walkways throughout that are accessible to those with disabilities, and levers instead of doorknobs. There’s also a smart-lighting system that automatically illuminates pathways to the bathroom when a resident gets out of bed. The kitchen countertops are made from the same durable glass as smartphone screens and require little upkeep.
The prototype would cost $385,000 to build. If the idea catches on commercially, Waldron said, economies of scale would bring down the price.
