Washington, D.C.'s Public Housing Scattered Site Demonstration Project targets public housing units that have deteriorated over the years and have become inhabitable. To pursue this work, seven nonprofit developers in the District have formed the Homeownership Group to take title to approximately 75 units, which are being rehabilitated for sale to first-time homebuyers as affordable housing.
One of the nonprofits, Manna, has developed nearly half the units--36 in total--as part of this program.
PATH's Demonstration project with Manna at the University Place Cooperative is part of the Scattered Site program. It is located in the Columbia Heights neighborhood in Northwest DC. University Place Cooperative encompasses the rehabilitation of 15 units. The finished rehab includes 5 one-bedrooms, 7 two-bedrooms and 3 three-bedrooms-all of which incorporated PATH strategies and technologies to a limited extent.
PATH provided expertise to Manna's design and construction staff in the following areas: Specification of building materials and products (particularly in the building envelope), fixtures, finishes, and appliances; design and specification of electrical, HVAC, and other mechanical equipment (such as hydro-coil units); energy use and heat gain/loss analysis and recommendations (including REM/Design and Manual J calculations); and education and training of subcontractors about new building materials and construction methods (for example, on-site training was conducted on OVE framing techniques and air-sealing practices).
While Manna's design and construction staff were very receptive to the suggested strategies and technologies, budgetary constraints prevented them from pursuing many of them. In the end, the following were installed to a limited degree:
- Light-colored bituminous roofing membrane
- Slag concrete
- Framing at 24" on center for exterior walls
- Air sealing
- ENERGY STAR® appliances
- Fluorescent fixtures in kitchen, common rooms, and stair wells
This project has been completed.
