Iowa State University has been accepted into the Department of Energy's Solar Decathlon competition for 2009. We are the first team to participate from the State of Iowa. Our project, the Interlock House, will be designed as a free-standing solar-powered dwelling that will generate enough energy for its needs and direct any surplus to the grid or a companion house nearby.

Spaces. It is designed to be constructed within an established community to connect with the site's existing infrastructures, not only its utilities, but its educational, commercial, transit, and social networks. Inhabiting in-between spaces in already developed neighborhoods is a strategy for community densification and an alternative to sprawl, especially in rural and suburban areas. The house will also enable people such as retirees, empty nesters, college students, or members of extended households to stay in neighborhoods which they might not be able to afford otherwise.

Less Energy, Less Waste. In addition to creating new energy-efficient housing options within existing neighborhoods, the Interlock House demonstrates a new practices of residential construction that uses less energy, creates less waste, and helps develop local enterprise. The house aims to build a safe and healthy environment for its occupants by addressing and surpassing ASHRAE standards. Key among the house's innovative material features are building components with recycled and recyclable materials such as agricultural waste (bio-composites) and a water system that minimizes reliance on offsite infrastructure including storm water drainage systems.
