Sustainable Attainable House
Affordable Green House Prototype
The Maine State Housing Authority hosted a design competition inviting architects, builders, students and anyone else, to submit plans for an affordable house design that was affordable, innovative, and easily reproduced. Each design submitted was to be buildable at a construction cost of 150 thousand dollars or less (excluding site). Green Design Studio (Briburn's previous name) submitted the Attainable Sustainable House. Simplicity of form and energy efficiency make this design affordable. Its rectangular footprint, mono-pitched roof, structural insulated panel (SIP) wall construction, and single span joists simplify construction, yielding a very cost effective home. The passive solar design contributes 46% of the home’s annual heating needs while shading it from summer sun. The high efficiency gas boiler, in combination with the solar hot water system, makes up the remainder at an estimated annual cost of only 540 dollars.
