Tour Energy-Efficient Home in Westport, Connecticut

On Sunday, November 11, 2012, there will be an opportunity for a guided tour of the Bauhaus Residence in Westport, Connecticut. Designed in 1934 by a disciple of Frank Lloyd Wright, the home was in dire need of renovation in 2011. The cast-in-place concrete structure is a striking example of the International Style in rural New England. Unfortunately the original concrete walls required a tremendous amount of energy to keep warm in the winter. In order to increase the energy efficiency and comfort of the house, architect Ken Levenson clad the entire building in ten inches of Foamglas insulation. With a passive solar hot water heating system, triple-glazed European windows, and an energy recovery ventilator, the award-winning project is going for Passive House retrofit (EnerPHit) certification. Gregory Duncan Architect performed the energy modeling and thermal bridge calculations required for certification.
