A townhouse in Herndon, Virginia had been neglected for nearly 20 years. When Roger Lin, a principal at Southern Exposure Homes, bought the investment property, he knew from the start that he wanted to do more than simply make minimal fixes before putting it back on the rental market. He was on a mission to prove that even older, ill-repaired homes could be economically transformed into models of efficiency and performance. He also knew that the single most significant energy waste in most homes today is caused by leaks in the property’s air duct system. So, one of the first items on his renovation “To Do” list was to have the ducts sealed with Aeroseal.
Lin represents a growing legion of building renovators that are passionate about home energy performance and engineered comfort. He can’t just retrofit a house – he is driven to make his properties as efficient as practical. Aiming to have the Herndon townhouse officially receive a low HERS rating (signifying high energy efficiency), he implemented a number of energy-saving upgrades – from insulating the roof, walls and floors, to using special sheeting material to help get the house air tight. When he first heard about Aeroseal duct sealing, he dug deep into the research and found that the duct sealing technology could have a dramatic impact on indoor air quality, comfort and energy savings. The research showed that effective duct sealing is typically the single most effective thing a homeowner can do to reduce home energy usage. He also learned that it was one of the least expensive energy retrofit options available in terms of cost vs. BTUs saved.
Aeroseal reduced the townhouse duct leaks by 95%, which had a dramatic impact on lowering the property’s heating and cooling costs, improving indoor air quality and increasing overall comfort throughout the home.
