Energy Conservation with Old Houses
Michael Blasnik, an independent consultant for over 25 years, specializing in energy efficiency, building science, and weatherization, conducted a study in Upstate New York. He found that people who had replaced their windows -- which can cost $10,000 and more for an entire house -- saved about $40 on their annual heating bills. At these rates, homeowners wouldn't see a net cost savings for another 250 years! Old wood windows, however, were built to be repairable. The Fine Homebuilding Magazine April/May 2010 article, "Should Your Old Wood Windows Be Saved?" is an illustrated problem-and-solution guide that is available at the Anacortes Library (Fine Homebuilding 210, pp 40-43). Also, "New Life for Old Double-Hung Windows", by John Michael Davis is available at the Anacortes Library (Fine Homebuilding,Dec 2007-Jan 2008. pp.76-79).
