Don't be fooled by the cottage-chic exterior of the Green Home garage. This hard-working two-car garage will house the GMC Yukon Hybrid that is part of the Green Home giveaway, plus the golf cart that comes with all homes in Tradition. It's also the hub of the Green Home's solar power and rainwater harvesting systems.

The Green Home generates about 10 percent of its own electricity through solar power, with a photovoltaic system located on the south roof. In addition, rainwater from the roof is harvested in an underground cistern and piped through the garage to supply water to the toilets.
