Case Study: Greening Student Life By Greening Residence Halls


Published on

Residence Halls provide an interesting challenge for green designers because so much of the impact is based on behavior-change and education. Cannon Design presents a case study on Worcester Polytechnic Institute’s new LEED Gold Certified East Hall.

East Hall, WPI’s newest residence hall, was designed to support the Institute’s vision and mission to foster innovation and creativity. Not only does the building provide apartment style living space for students but additionally, collaborative in high-tech media suites and amenity spaces that encourage student wellness and life balance.

The building supports and encourages ongoing research relative to both energy and water use and continues to provide a living learning environment that extols the benefits of sustainable lifestyles. Open 3 years, East Hall continues to serve as a focal point for yearly student IQP’s (Interactive Qualifying Project) where students are encouraged to complete a project that relates technology and science to society or human needs, often relative to the green roof and associated monitors installed at East Hall.

  45. 45. MOVING FORWARD: WPI WPI has a commitment through it mission to educated students through theory and practice. When the PCC was introduced, WPI felt there was a lack of clarity on the literal implications it had. We do not believe that we have enough information to credibly meet those targets. WPI remains committed to sustainability, to the environment, and to reducing our carbon emissions. WPI is collecting information to understand our current levels, the impact of recent projects, and the implications this may have on our growth and master plan. WPI needs to understand the impact on operations and on our future. As this evolves, we are discussing what levels are reasonable and by what time. WPI continues to participate in many of the initiatives noted in the PCCC.

  66. 66. MOVING FORWARD: DO’S Complete POE’s Review Assumptions and Learn from Mistakes   Conclusions Overall, WPI’s East Hall is a great example of sustainable building. Electric usage data shows the building performing much better than even designed. Even with our analysis and possible skewed water modeling, the building is definitely using less water than a conventional building. East Hall’s educational outreach is providing a great source of information about sustainable design and its benefits. East Hall is serving its purpose as an excellent example of a LEED Gold certified building. CIVE5270 Environmental Protection and Management By: Yixing Cao and Michelle DiBenedetto
