With its unique “diagrid” design, the Hearst Corporation’s new $500 million, 46-story steel and glass tower in midtown Manhattan has a tremendous impact on the city’s skyline. It also has a tremendous impact on our environment. Constructed largely with recycled and resource-efficient materials, featuring heat conducive limestone, polyethylene water circulation tubing, and a rainwater irrigation tank, the building was awarded a LEED Gold Certificate in 2006. Tasked with creating equally efficient building management operations, TEC produced a system synced on Honeywell’s EXCEL 5000® Open™ technology. The system was successfully integrated with the building’s energy designs, and features automated daylight sensors, variable-speed fans, and spill-air technology, in full compliment to the tower’s eco-friendly mission.
