The house and barn in Westford were redesigned and constructed to demonstrate the ability to reuse sensitive historic structures for modern uses through advanced technologies which pro-vide for energy efficiency, durability, good indoor air quality, reduce costs, and improve comfort. The 1850’s house interior was redesigned to allow for a modern kitchen and small rooms were opened to each other. The attic was insulated to R-38 and converted into a finished space with two additional bed-rooms and a full bath. Mechanical ventilation was also added. The basement walls and floor were insulated to R-10 and R-10 sheathing was added to the exterior walls.

Building Science Corporation Office SectionThe barn was redesigned to retain its original character as a barn while providing comfort and power for a modern office setting. The interior is the original board sheathing. The exterior is covered with 8-inches of rigid EPS insulation on the walls and 10-inches on the roof. As in the basement, the crawlspace walls and floors were insulated to R-10. A high efficiency combo system provides heat and hot water and a controlled supply mechanical ventilation sys-tem provides for good indoor air quality. The house and barn renovation exceed Energy Star requirements, receiving a score of 91.3 out of 100 points.
