Field Test Data from Retrofit of a Small Residential House Using EISF Technology

The post-WWII housing boom in North America has mirrored the baby-boom that came with it. We now have a very large number of houses that are in need of special care. They are typically well-built, ‘right-sized’, on smaller lots, close to municipal services such as mass transportation. This makes them the perfect target for energy upgrading. This presentation will describe how a 60-year-old house in Maine was selected and retrofit with an exterior insulated cladding system that increased the wall thermal performance to R30 with no disruption to the interior. The house was monitored for a year before the retrofit and then monitored for a year following. The paper will document how the walls were retrofit, the detailing to accommodate existing conditions, the sensor placement and the validation of the modeling done in support of the work. The energy modeling part of the presentation will demonstrate the long-term energy savings and durability of the house.
