Redeveloped Butler College
 |
In University-led studies to be conducted over the next few years, faculty and students from the Princeton Environmental Institute (PEI) will learn just how much energy can be conserved and stormwater runoff reduced by comparing green features with conventional ones at the redeveloped Butler College complex. Here, Jessica Hsu, a rising senior majoring in civil and environmental engineering (left), and Eileen Zerba, a senior lecturer in ecology and evolutionary biology and director of undergraduate laboratories at PEI, check the sensors on a mockup model located on top of a Butler green roof. photo: Princeton University, Office of Communications, Denise Applewhite (2009) |

Roofs on more than half of the Butler buildings have been planted with 14 varieties of hardy sedum. The contrasts in the palette of the many-hued rooftop garden will intensify as summer turns to fall. photo: Princeton University, Office of Communications, Denise Applewhite (2009) |

Thermograph readings recording surface temperatures taken in June of the Butler College rooftop show the green roof (right) to be cooler than the conventional roof (left). The conventional roof was 107 degrees Fahrenheit, with the green roof registering at 88 degrees Fahrenheit. Keeping the rooftop cooler can cut energy costs, especially for air conditioning, and reduce the building’s carbon footprint. photo: Princeton University, Office of Communications, Jessica Hsu (2009) |

Butler Memorial Court honors the group of classes that generously supported Butler in the past and is paved with bluestone salvaged from the original buildings. The unique gathering place houses a 5,000-gallon underground stormwater storage tank to collect rainwater runoff from the roofs to irrigate the landscaping. photo: Princeton University, Office of Communications, Brian Wilson (2009) |

The five contemporary two- to four-story dormitories, which are connected at the lower level, are adorned with warm red brick accented with limestone. Architect Henry Cobb said he purposely sought to enliven the architecture through the narrow bands of limestone as well as the irregularly spaced wave-like undulations on the buildings' fronts that allow for larger bedrooms in upper-class suites. photo: Princeton University, Office of Communications, Brian Wilson (2009) |

The new Butler complex is expected to house 283 in student rooms such as this one. There will be 41 single suites that consist of two single rooms with a bathroom between them; 59 quad suites with two bedrooms, common area and private bathroom to house four students each; plus six residential college adviser suites, two resident graduate student suites and one resident faculty suite. photo: Princeton University, Office of Communications, Brian Wilson (2009) |
