The U.S. Dept. of Energy Solar Decathlon 2011:

Parsons the New School for Design and Stevens Institute of Technology’s team built the cheapest house in this year’s decathlon. Spending $229,890 on its high-efficiency, solar-powered home, the team tied with Purdue University in the affordability contest on Tuesday. Purdue spent about $20,000 more, however, both teams were below the target construction cost of $250,000 or less.

This year, the Parsons-Stevens team is partnered with Habitat for Humanity of Washington, D.C. The team’s student architects designed the home to accommodate a single parent with an annual income of about $50,000. The team’s market strategy specified that the “family must have experienced unsafe conditions or a severe rent burden in its current home and demonstrate a willingness to participate in the construction and maintenance of the house.”
