In one six-story 83-unit co-op in New York City, Jane Sanders and Mario Bissessar are taking small steps to make a big impact over time by performing a high-performance retrofit of a single unit. Jane Sanders will present the design challenges and plans for this single unit retrofit at the Global Passive House Happy Hour on June 16. Currently, Jane serves as a senior associate and director of sustainability at Henson Architecture.
