Courtesy of: ReVision Energy, LLC TerraHaus, the nation's first certified-passive dormitory, will be open for tours on Saturday, October 13.

Visit solar powered buildings across Maine this weekend as part of the Green Building Open House tour, Saturday, October 13 from 10 AM to 4 PM. The tour is free and open to the public.

Three buildings at Unity College, located at 90 Quaker Hill Road in Unity, will be part of the tour – they include:

-          TerraHaus, the first Passive House-certified student residence in the country. This building features an evacuated tube solar hot water system, super-insulation and superior air sealing with backup heat from a cold-climate heat pump and small electric baseboard radiators. Evacuated tube solar hot water collectors provide more than 60% of the building's annual domestic hot water needs.

-          Unity House, the on-campus home of Unity College's president and family. This net-zero carbon residence is a symbol of the college’s sustainability outreach efforts, and features a 5.4 kW photovoltaic array, a solar hot water system, and a cold climate heat pump. This LEED Platinum home for the college president uses passive solar design, high-efficiency thermal insulation, and was built with recycled, non-toxic, locally sourced materials.

-          The Quimby Library, where 144 solar electric panels were recently installed by ReVision Energy. This 37 kilowatt grid-tied array will produce 80% of the building’s electric needs annually.

Another green home in Unity, also on Quaker Hill Road, is participating in the tour. Rusty Mayberry will be giving tours of his family’s solar powered home, which features a 60 tube solar hot water array and a 3 kw grid-tied solar electric system. These solar arrays are estimated to help the Mayberry family offset over 10,500 lbs. of CO2 annually and save them over $1,500 annually at today’s oil and electric prices.
