Princeton's Green Roofs... www.princeton.edu … From August 2009 - Faculty, students and staff involved in a monitoring project are measuring the effectiveness of sustainability efforts on the newly installed Butler College green roof.
When 283 Princeton undergraduates move into Butler College this September (2009), they will be entering a 113,000-square-foot complex integrating sustainability features from top to bottom, including the green roofs on more than half of its buildings and a stormwater cistern that will collect and recycle rainwater to irrigate courtyard landscaping./n"Green roofs provide many ecological and aesthetic benefits, from cooling the roof surface, to helping ease the urban heat-island effect, and creating a wildlife habitat," said rising Princeton University senior Jessica Hsu, a civil and environmental engineering major. This summer, she compared temperatures of green and conventional roofs across campus using infrared technology as a Princeton Environmental Institute (PEI) summer intern, along with faculty mentor, Eileen Zerba, a senior lecturer in ecology and evolutionary biology and director of undergraduate laboratories at PEI.
