A recently completed remodeling project in Munster, Ind., is the first home remodel to earn certification under the National Green Building Standard, according to the National Association of Home Builders.

The 1,100-square-foot ranch home built in 1974 was renovated by Lyng Builders after floodwaters filled the basement, as well as two feet of the first floor.

The builders also persuaded the homeowner to make improvements to help save on utility bills by decreasing energy and water consumption and to obtain national green certification through the NAHB Research Center.

Improvements include: upgrade of the heating and cooling system; installation of a high-efficiency water heater; selection of Energy Star-rated appliances; the addition of wall and pipe insulation; thoroughly sealing the home against air and energy leaks; replacement of the faucets and toilets with low-flow fixtures; and installation of a programmable thermostat, a power-vented attic fan, and a programmed exhaust mechanism for efficient conditioning and ventilation.
