3 Green Roofs

Hamerschlag Hall, Porter Hall, and Doherty Hall all have green roofs. A green roof reduces cooling and heating energy consumption, protects the roof's structural elements from UV rays, extends the life of the roof, and lowers storm water waste streams. Carnegie Mellon currently has 5,644 sq. ft. of green roof tray systems and 35,515 sq. ft. of green roof space. Learn more: cmu.li/VCBuU #The12DaysOfEngineering
