The teams of students who participated at this year’s Solar Decathlon were instructed to design their energy-efficient houses for $250,000 or less. Solutions included some pointedly avant-garde designs. Yet some students and faculty advisers worry that the Decathlon’s new emphasis on affordability will deter innovation and lead to the construction of more-pedestrian homes. Other participants found fault with the system for estimating costs. Nevertheless, a few entries succeeded in making a significant point: Going green can have mass-market appeal.
