Cool Collaborations: Weatherization in Vine

Have you ever wondered what the steps are to weatherize a home? You may have noticed a draft around a window or door, but do you know how much heat is actually escaping your home and from where? And do you know how to improve the air sealing in your home enough to make a difference? Community Homeworks has just completed a pilot project with the Vine Neighborhood Association to work with a group of homeowners, tenants and landlords to weatherize eleven homes and apartments. The project was designed to bring Community Homeworks’ technical expertise and supervision together with the residents own efforts to produce real energy savings.

The first step in a weatherization project is to do an audit to determine how much air loss is happening. Have you ever heard the term “blower door test“?

Each home and apartment in the project had an initial blower door test performed. All the participating residents were trained by Community Homeworks on how to do the necessary air sealing of their homes using caulk and insulation. The goal was to achieve a 20-30% reduction in air infiltration in the second blower door test. Once that goal was achieved, Community Homeworks installed high-efficiency furnaces in each residence (and several new water heaters where needed). More than $70,000 in improvements were made in the 11 homes – residents can anticipate 25% or more in energy savings going forward. We are looking forward to evaluating the results of this pilot and continuing to develop innovative ways to bring the benefits of energy savings to the community.
