Title: 56th and Walnut: A Philly Gut Rehab Development; Philadelphia, Pennsylvania (Fact Sheet)

Load-bearing brick-masonry multifamily buildings are prevalent in urban areas across much of the Northeast and mid-Atlantic. In most instances, these buildings are un-insulated unless they have been renovated within the past two decades. Affordable housing capital budgets typically limit what can be spent and energy improvements often take a back seat to basic capital improvements such as interior finish upgrades and basic repairs. The Consortium for Advanced Residential Buildings (CARB) is researching cost effective solution packages for significant energy efficiency and indoor air-quality improvements in these urban buildings. To explore how these low-cost retrofits can effectively integrate energy efficiency upgrades, CARB partnered with Columbus Property Management and Development, Inc. on a community-scale gut rehabilitation project located at 56th Street and Walnut Street in Philadelphia, consisting of 32 units in eleven 3-story buildings. These buildings were built in the early 1900s using stone foundations and solid brick-masonry walls. They were renovated in the 1990s to have interior light gauge metal framing with R-13 batt in the above-grade walls, induced-draft furnaces, and central air conditioning.
