Modern History: America’s Oldest Net-Zero Home

By installing state-of-the-art technology and alternative energy systems, self-described “average couple” Kelly and Matt Grocoff transform their century-old house into a cutting-edge net-zero home.

In addition to turning off when occupants exit, the home's automatic lighting controls can be set to turn on when someone enters a room and adjusted to ambient light levels, meaning lights don't turn on when there is plenty of daylight.
