425 Grand Concourse is not just the biggest Phius Passive House building to date, it's also a model for democratizing the benefits of healthy and resilient buildings. With 277 residences, a grocery store, a medical facility, and CUNY campus space all within a single airtight envelope, this high-rise in the Bronx might just be the future of housing. The building was recognized by NYSERDA, the New York State Energy Research and Development Authority, as a Building of Excellence.
