"We contacted Trillium to design a passive, energy efficient home that would meet the highest standards for green homes in the United States. The home also had to meet local historic district requirements, while also being an aesthetically pleasing home for a faculty family. We are very pleased with the results!" - James, Taft Facilities Manager

The Taft School wanted to build a state-of-the-art green home to support the school’s commitment to faculty housing and environmental stewardship. This is a single family two-story, three bedroom, two and a half bath home with a detached two-car garage, located in the Historic District of Watertown, CT. The home is oriented to optimize the use of passive and active solar energy and the energy usage is monitored by the residents and students in the classroom.
