Here's what makes it so:
• Oriented so rooftop solar panels are at most effective angle.
• Made of Rastra block, which is recycled Styrofoam and concrete.
• Designed so afternoon breezes sweep hot air up and out of house.
• Bamboo floors.
• Counters made of recycled newsprint and resin.
• Carpeting made of corn. And more.
