With homeowners concerned about increasing energy costs, it's more important than ever to emphasize conservation, she said.

Standard green-building features include an interactive display that provides homeowners with real-time and historic feedback on electricity and water consumption, energy-efficient appliances and an advanced lighting package.

With a solar-panel system and General Electric "ecomagination" products, a 2,700-square-foot home can reduce the average electric bill by 70 percent, from $300 a month to $90 a month. Monthly utility bills vary based on home size, location, construction characteristics, number of occupants and their lifestyle, temperature settings and other factors.

Sommerset homes will range from 1,700 square feet to 2,700 square feet with three to five bedrooms. Prices start in the mid-$300,000s.

Residential housing represents 20 percent of all greenhouse gas emissions, according to the U.S. Environmental Protection Agency. The average home actually pollutes more than the average car.

The EPA hopes to reduce annual carbon emissions by more than 3.5 million metric tons by 2012, the pollution equivalent of removing 3 million cars from the roads, just by improving the energy efficiency of homes.
