    Weatherization & Deep Energy Retrofit Projects

    Weatherization
     
    Weatherization

    We started weatherizing structures in 2008. A good first step in improving the energy efficiency of an existing home is to have an energy audit. Paul Kando and Topher Belknap are the auditors we have worked with the most. Their contact info can be found on the Midcoast Green Collaborative web site: www.midcoastgreencollaborative.org

    One of our weatherization projects was at an elder care facility, Round Pond Green, in Round Pond, Maine. We were to perform standard work adding cellulose insulation to the exterior walls and 2nd floor ceiling, insulating the basement ceiling, and air sealing. As we began the project we were asked to design and price additional work that included turning 1800 square feet of 2nd floor space into apartments and offices.

    We included an option to add 2″ of polyiso foam board to the inside of the exterior walls and to lift floor boards at the exterior walls so we could insulate the rim joists. The option was accepted and we performed a DEEP ENERGY RETROFIT. The diagram to the right shows the procedure.

    As a result 1800 s.f. of heated space was added and less oil was burned the next heating season for the entire structure.
