Sealing Air Leaks, Adding insulation and Reconnecting Ductwork
A customer of Fleming-Mason Energy was having a tough time paying her high electric bills. Living alone in a two-story, stick built home, this customer could not see how her modest sized home, with the thermostat set in the low 60s, could create such high usage and cost in the winter. Fleming-Mason recognized that this woman’s house would be a good candidate for the How$martKY program. In a unique partnership, Fleming-Mason was able to have both the audit and the home improvements completed by People’s Self-Help Housing (PSHH) in Vanceburg. PPSHH is a non-profit housing group experienced in energy efficient housing.
After a comprehensive whole house energy evaluation by highly trained staff using state-of-the-art testing equipment, two major problems were identified:
• Very high air leakage from the house to the attic
• Very leaky ductwork in the crawl space underneath the first floor
In fact, much of the original ductwork was not connected at all, meaning the majority of warm air that should have been delivered into the home was instead heating the crawl space. In addition to fixing this major problem as well as adding spray foam insulation to the walls in the crawl space, and reducing the air leakage by almost 40 percent, People’s Self Help Housing was also able to use the resulting energy savings to fund additional improvements that were needed to make the home more durable. Those improvements included diverting rainwater away from the foundation and venting the dryer to the outside.
With the improvements now completed, the customer is looking forward to a lower electric bill. She has already noticed an improvement in the comfort level of her home saying, “it’s a lot warmer now” on cold nights.
