Winchester Housing Authority Palmer Street Apartments

Energy Audit and Blower Door Air Leakage Test

Winchester Housing Authority Palmer Street Apartments is a 52 dwelling unit senior citizens subsidized complex built in 1974.   All apartments are one bedroom.  The complex is comprised of six (6) brick faced masonry buildings with newly installed attic insulation of 12 inches.   All the building have new vinyl windows.  There are four three-story walk-ups, one single story handicap building and a community building with central laundry.   The complex is heated by electric baseboard.  DHW is supplied by 120 gallon electric tank type heaters.  The apartments are cooled by window air conditioners. The foliage around the site is very mature resulting in limited potential for renewable energy generation on site.   The common area lighting recently been upgraded with high performance T-8 fluorescent lighting.  

The results of the blower door test can simply be summarized in a simple statement.   The buildings are more airtight then the existing building code (Massachusetts Stretch Code). At  a measured rate of 5.9 ACHnat is between the Stretch Code (7ACHnat) and the Massachusetts latest building code (5ACHnat).  We identified the two major sources of air leakage and being the original aluminum frame sliding glass doors and missing sealant between the pre-cast concrete flooring planks.

The three (30  major energy improvements we identified two potential ECMs (energy conservation measures) for the complex.
