Conducting an energy retrofit of our first home, a neglected 1852 Greek Revival, provided us with hands on experience and knowledge. We were looking for a new project and were alerted to a vacant historic 1830 farmhouse. The front of the home faces south and a bike path that leads to our town center is located on the north side of the property. After walking through the dilapidated building we could see the hidden value of the structure. We envisioned it powered 100% by the sun.
We set three goals for the project, to maintain the historic character, make the renovation sustainable and green and provide an energy efficient building.
We started demolition only to find substantial insect, water damage and other structural issues that greatly increased the scope of work. Our architect incorporated the newly found damage as well as other ideas from the Building Science Corporation book “Builders Guide to Cold Climates” by Lstiburek and ideas from the book “Prescriptions for a Healthy House” by Baker-Laporte, Elliott and Banta.
We built new partitions inside the existing exterior walls using offset studs, allowing us to increase the insulation, as well as provide a thermal break. The new wall cavities were filled with approximately 8” of closed cell foam. After replacing the second story roof structure (inadequate for the expected snow loads) we filled the rafter spaces with closed cell spray foam, covered the decking with a recycled rubber roof underlayment, 4 inches of Styrofoam insulation, and finally a standing seam metal roof.
The design required us to preserve the existing room layout and south facing facade of the building. We renovated the facade by reinstalling wood siding, rebuilding the porches, existing double hung windows and wooden storms. In addition, we installed magnetic interior storm windows over the existing windows to increase their energy efficiency.
Care was taken in choosing systems and products for energy reduction as well as local sourcing to reduce our construction and operating carbon footprint.
