DVGBC 2016 GROUNDBREAKER AWARD
DVGBC's jury selected the Pennsylvania Housing Finance Authority (PHFA) Project for the 2016 Program Award recognition. The PHFA Project is the result of the organization introducing language into their competitive funding application process which encourages developers to build to Passive House standards, a hyper-energy-efficient standard.
The PHFA Project began in 2014 when Tim McDonald, under the auspices of the Architectural Research Center, a think tank housed within the Temple University Architecture program, approached Stan Salwocki and Holly Glasuer from PHFA with the suggestion that all affordable housing be net-zero energy capable by 2030. McDonald's design/build firm, Onion Flats, had already built Belfield Townhomes, Pennsylvania's first Passive House project, serving formerly homeless families and as a proof of concept that Passive House projects can be built on affordable housing budgets.
