DESCRIPTION

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.

• (2) 26W compact fluorescent open downlights

• Downlights provide adequate ambient illuminance all around bedroom with some cutoff along the long sides of the room

• This option is very flexible –furniture can be placed anywhere without affecting the quality of light in the room

• This option requires the students to provide their own desk lamps = more energy usage and potentially dangerous lamp types (such as halogen)

• Power density = 0.53 watts/sqft, but introducing an incandescent task light will raise power density to 1.45 watts/sqft

• (1) 26W compact fluorescent open downlight, (1) task ambient T5 fluorescent desk light with up/down component

• Downlight provides adequate ambient illuminance at bedroom entrance, wardrobe, and center of bedroom

• Task ambient light provides adequate surface illuminance at desk, and ambient illuminance mostly on “desk side” of bedroom

• This option is very flexible – the task ambient light moves with the furniture

• This option reduces the number of student-owned incandescent desk lamps introduced = less energy usage

• Power density = 0.57 watts/sqft• Provides the best light coverage with the

least amount of fixtures

Environmental and Ecological Benefits for WPI• Reduces the Urban Heat Island Effect , bldg replaced 3 large parking

lots and 2 bldgs.• Reduced green house gas emission (Co2 emissions) as a result of

reduced energy use by air conditioners and baseboard heaters helps WPI meet the Presidents Climate Commitment

Water Conservation• Green Roof absorb rainwater minimizing stormwater infrastructure

Air Cleaning • Improves the air quality, the green roof filters the air moving across it • 10 square meters of grass on a roof can remove 2 kg of pollution

particles from the air per yearCreation of Habitat • The green roofs provide a habitat for songbirds, butterflies  and bees

Planting details at East Hall

Page 39: Case Study: Greening Student Life By Greening Residence Halls

Green Roundtable 2010

Reduction of Waste • Green roofs protect roofing membranes from extreme temperature

fluctuations • The life span of East Hall’s new green roof is twice as long as a

conventional roof so decreases the need for re-roofing and consequently, less waste roofing and construction materials will end up as landfill

Social Benefits • The roof specimans will serve as a learning environment for residents

and the community on issues of energy, resource efficiency, bio-diversity, barrier-free gardens and gardening, storm water management and renewable energy sources

• Increased visual appeal for upper campus

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.

Why Conserve Energy?

The simplest energy conservation measures can save the University millions of dollars in costs annually. But, energy conservation does more than just save money; it reduces damage to the environment and helps minimize social costs.

Just to get a feel for how important energy conservation is, here are a few of the social costs attributed to energy consumption: diminishing wilderness areas due to oil and gas exploration, our growing dependence on foreign oil and the risk of conflict over shrinking energy resources. Remember, conservation reduces air and water pollution, acid rain, and global warming.

Just to get an idea of the amount of money the University would save, check out these facts:

Over a million dollars a year goes to water and electrical utilities – 13% of your housing bill pays for the 420 dollars of utilities you use.

If each student uses two 60 watt light bulbs at .12 cents an hour, the University pays out $134.40/hour just to turn on the lights.

If 75% of WPI students leave their computer on for 12 hours straight, it costs $1,493/day.

If 117 laundry dryers are used for 5 hours a day, it would cost $234/day.

Imagine how much money the University would save if every student tried to curb his or her utility consumption by even just 25%!

Computer Conservation Tips

Personal computers account for approximately 1.5% of all energy consumption. One computer left on 24 hours a day uses between $65 and $115 annually and dumps 850-1,500 pounds of carbon dioxide into the air. Here are a few things you can do to help conserve energy:

Turn your computer off at night or when you are away If the computer is going to be inactive for greater than 15 minutes, consider

shutting it down. After this time, the energy needed to run the computer is greater than the energy needed for start-up

Do not turn the printer on until you are ready to use it Most computer equipment now comes with power management features (Energy

Star), please use them Despite the name, screen savers do not save anything, so turn off your monitor

when not in use. Flashing images actually consume as much energy as during active use

IQP’s- Interactive Qualifying Project

The Interactive Qualifying Project (IQP) challenges students to address a problem that lies at the intersection of science or technology with society. During the IQP, students work in interdisciplinary teams, often with an external sponsoring organization, to develop solutions to real world problems. In doing so, students learn something about the role of science and technology, its impact on society, its place in meeting human needs and human efforts to regulate, control, promote and manage our changing technologies.

In the Fall of 2007 Sophomore Sally Trabucco and Freshman Karalee Conover attended the North East Affiate of College and University Residence Halls (NEACURH) Regional Conference at Ithaca College. NEACURH conferences bring together residential student leaders from across the northeast to learn from each other. At this conference these two students participate in a case study competition in which they were asked to create a sustainability program on campus. These students won first place in the region and brought their ideas back to the WPI campus where they shared their success and ideas with administrators on campus. This led to bottle and can recycling systems being placed in every residence hall. Sally later moved to be an RA in East Hall for her Junior and Senior year where she continued her work with sustainability, in our green residence hall.

Review Assumptions and Learn from Mistakes 

ConclusionsOverall, WPI’s East Hall is a great example of sustainable building. Electricusage 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.
