For the Corn Exchange Building, a New York Landmark building on Park and 125th Street in Harlem, Steven Winter Associates, Inc. (SWA) served as the Sustainability Consultant, providing energy modeling services and acting as the Commissioning Agent on behalf of 125 Street Equities and Artimus Construction.
Completed in 2014, this project transformed the 110 year old Corn Exchange (also known as the Mount Morris Bank) into a new seven story office and retail space. The original building was six stories tall, but decay and neglect led to the removal of the four upper floors in 2009 because of safety concerns. The two remaining floors were gut renovated and five new floors were added, for a total of seven stories. The $5.5 million project achieved certification under the LEED Core and Shell program and SWA provided LEED Fundamental Commissioning for this project.

With a total of 31,000 sf, the bottom two levels became 9,000 sf of retail space,  three levels of office space, and two levels occupied by the Harlem Culinary School. Originally built in 1889, the building earned landmark status in 1993. The original building was considered to be one of the finest architecture examples in Harlem. This project, initiated by the NYC Economic Development Corporation, sought to revitalize the neighborhood and reflect the past with some modern additions.
