Housing Nantucket is a nonprofit organization that develops affordable housing on Nantucket Island. The organization completed two green affordable housing projects - a two bedroom unit at 2 Clarendon Rear and a one bedroom unit at 3 Norquarta Rear. Both projects aimed to incorporate green building practices like energy efficient appliances and construction materials. While 3 Norquarta Rear did not pursue formal green building certification, it served as a learning experience. The document discusses the challenges and opportunities for developing green affordable housing, including higher upfront costs, gaining community support, and obtaining green building points related to water management and landscaping in the local context.
