4 John Wilson Ln, Lexington, MA 02421

Single Family Home for sale

Welcome to Minergy House. Uniquely designed by the original owner together with architect William Mead this passive solar home was built in 1980. A Passive Solar Energy Efficient home provides an open experience connecting you to nature and the fantastic view of the Daisy Wilson Meadow. Passive Solar means without mechanical devices.Minergy house has no furnace, no thermostats, no conventional radiators and has never used any fossil fuels. A spacious south facing greenhouse provides most of the space heating plus a ground mounted photovoltaic solar array in the side yard produces the electricity needed to operate the home. Excess energy is sold back to Eversource as permitted by the Massachusetts "net metering" regulations. The house currently operates as an energy-plus building, producing more electricity than it uses. Now, this is what you call a smart home! Showings will be conducted as short seminars with video to fully understand the home.
