Green home building is projected to encompass as much as 38 percent of the U.S. residential market by 2016, according to a study by McGraw-Hill Construction and the National Association of Home Builders, up from 17 percent in 2011. Spending on green home technologies (everything from energy-efficient windows to foam insulation to on-site renewable energy generation) is expected to rise to as much as $114 billion from $17 billion. Energy efficient appliances and windows, foam insulation, heating and cooling systems powered by geothermal solar panels and wind mills have all quietly begun invading new construction, particularly in the luxury end of the market. Lower monthly maintenance costs and tax incentives have helped fuel the demand.
