FAIRFIELD — The home of the future is here now — a cutting-edge, newly constructed house with a wealth of features that can be celebrated any time of year, but particularly Friday’s observance of Earth Day.

The Colonial at 161 Butternut Lane in the Southport section of Fairfield — north of Post Road (or Route 1) — was built in 2015 and has earned an Energy Star certification. Builder Chris O’Dell of O-Living Experience LLC gave the house extra insulation, a heat-recovery unit, LED light bulbs throughout and tankless hot water.

O’Dell made sure the spray foam insulation continues down the entire foundation walls, wrapping under the basement slab to enclose the entire house, creating an energy-efficient thermal envelope. "There’s no air leakage anywhere," he said.

He also designed exterior walls that are 9 inches thick, double the standard, "so this house is super tight," O’Dell said. But when houses are so well sealed the indoor air quality can suffer. O’Dell addresses that through an energy recovery ventilator, which constantly circulates fresh air throughout the house. It pulls fresh air from outside and pumps it into the house. "It’s like keeping your windows open year round," he said.

The outside air is tempered through the HVAC system so that no energy is expended

Additionally, this is a passive solar house. O’Dell gave it more windows on the south side and created cross ventilation when windows are open during warm weather months. He also installed a Savant Home Control system that allows the homeowner a way to manage the house the way they manage their lifestyle — through use of their cellphone. With the system a homeowner can monitor the property from afar and turn on and off the heat, air conditioning and lights.

The system can be customized to do anything remotely "from running your toaster to how much electricity you use on an hourly basis," he said.

Best yet, all the energy conservation features will have a favorable impact on monthly energy bills. O’Dell estimates there can be an overall savings of just under $1,000 monthly, although that figure depends on a family’s lifestyle choices.
