Prescott St. Apartments

February 25, 2016

Sanford, Maine

The Prescott St. apartment building was constructed for the Sanford Housing Authority to replace an aging structure with poor energy efficiency. When designer Lassel Architects performed a blower door test at the completion of the project to assess the building’s air sealing, a key indicator of a building’s energy efficiency, the initial test resulted in a reading of 0.17 ACHnat (air changes per hour), significantly better than the Maine State Housing Authority target of .20 ACHnat.
