Gregory Duncan’s interest in high-performance building began while working on a deep-energy retrofit of an office building in Hamburg, Germany in 1996. He returned to the United States to obtain a Master of Architecture degree at the University of Pennsylvania. Working in New York and New Jersey since 2000, Mr. Duncan has acquired a significant amount of experience with building construction, particularly in the mid-rise multifamily, townhouse retrofit, and small commercial areas. Complementing his practical experience, Mr. Duncan works to advance the theory of green design and building science. He is a Registered Architect in New York and New Jersey, a LEED Accredited Professional, a Certified Passive House Designer, and a Vice President of New York Passive House.
