Updating The Old To Be New Again:

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.

Mechanical systems include a 3 ton ground source heat pump, a heat recovery ventilator and a whole house dehumidifier. Renewable energy is provided by pole mounted 8.4 kW photovoltaic (PV) and solar hot water (SHW) systems in the rear yard. We located the PV and SHW systems separate from the structure to maintain the historic facade of the structure.

Interior work include American Clay finish over all walls, a milk based poly whey coating for all exposed wood finishes, paper stone counters and a local Amish cabinet maker crafted oak cabinets.

The project met our three goals! We received the 2011 Town of Clifton Park Historic Preservation award and Town Conservation Easement, earned LEED Platinum and NAHB Certified Green Building Emerald awards and a NYS Energy Star rating. For the first year the local utility paid us for our excess electricity. We are now using the excess carbon free energy generated to power a 2012 Nissan Leaf and a 2012 Toyota plug-in Prius to help cover our transportation carbon footprint.

Occupancy Statement:
The building, 4 Balsam Way has been continuously occupied by at least 2 persons since we moved in January 2011 to now, November 2012. For the first 6 months we had a teenager living with us while she went to school locally. In the almost two year period, with an exception of two weeks this last summer and an occasional overnight visit to our families we have lived here continuously. One occupant is retired and home most all day and second occupant is a school teacher and works 10 months per year. Person days of occupancy = 1485.

Cost of Project and Square Footage of Conditioned Space:
The building has 2134 sq. ft. of conditioned space. The house construction costs were approximately $288,000 (minus barn, driveway, landscape, design and legal fees) or approximately $135 per sq. ft. (including PV, GSHP and SHW).
