Project Details
A massive redevelopment of the 1940s-vintage Mercy Hospital campus in Portland, Maine, features two of the state’s first all-electric affordable housing projects, including 95 units designed to Passive House performance criteria. They are among the first projects to meet Portland’s Green New Deal energy efficiency standards.
Winter Landing’s energy footprint is 34% more efficient than that specified by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Collaboration between our structural and sustainability teams, in coordination with CWS Architecture + Interior Design, accelerated accurate energy modeling for thermal bridging and insulation details.
Next door, we provided sustainability consulting to Ryan Senatore Architecture for the equally energy-efficient Equinox development, which includes 43 of the 95 units. The annual operational energy cost savings projected for both developments is $57,000, compared to the widely used ASHRAE baseline.
The rental units, developed by Community Housing of Maine and Portland Housing Development Corporation, provide homes for residents earning less than 60% of the area’s median income, help alleviate a rental housing shortage, and provide walkable access to the city’s West End neighborhood.
