Williams College Receives Rebate for Green Building

May 4, 2008

$92,670 from Massachusetts Technology Collaborative for Solar Energy Design

Williamstown- State Senator Benjamin B. Downing (D-Pittsfield) and State Representative Daniel E. Bosley (D-North Adams) are pleased to announce that Williams College will receive a Commonwealth Solar grant from the Massachusetts Technology Collaborative (MTC). This award recognizes the commitment to renewable energy Williams College has demonstrated by incorporating solar power on campus. “I applaud Williams College for leading the pack in constructing a sustainable, green building that will serve as a model for future construction projects, and for their pledged commitment to reduce the amount of greenhouse gas they emit. I am pleased MTC has recognized their vision and awarded this grant,” said Downing.

As part of their library renovation project, Williams College is constructing a library shelving facility and will install a 26.88 kilowatt photovoltaic system projecting an output of 29,559 kilowatt hours of solar power annually. The Commonwealth Solar program estimates that the output of this system is equivalent to planting 76 trees a year. This new facility will be used to house special collections and works that are not available for regular circulation in the main library. Library staff will retrieve materials as requested for anyone wishing to lend or have access to them.

“I am pleased to see MTC supporting the continued leadership and dedication of Williams College to renewable energy, environmental stewardship, and the education of young people about clean energy technology. It is a good example to be setting – both for the students and the region as a whole- and a perfect example of how we imagined the Renewable Energy Trust Fund working when we created it in the 1997 energy legislation,” said Bosley.

This award, a $92,670 Commonwealth Solar rebate, will help the College defray the total costs of the project which spokesperson and Acting Director of the Zilkha Center for Environmental Initiatives Stephanie Boyd estimates at roughly $300,000. “Speaking on behalf of Williams College and the Zilkha Center for Environmental Initiatives, we are thrilled to receive this grant in support of the first significant photovoltaic installation at Williams College,” said Boyd. “The renewable energy generated will help the College achieve its ambitious greenhouse gas reduction target of 10 percent below 1990 levels by the year 2020.”

Commonwealth Solar grants are available to homeowners, businesses, non-profits and municipal customers located in investor owned utility areas of the Commonwealth. Awards are in the form of rebates from the state’s Renewable Energy Trust and the Alternative Compliance Payment Funds that the Massachusetts Division of Energy Resources has collected under the state’s Renewable Portfolio Standard program.

A total of 16 awards amounting to $271,940 will be disbursed this funding round.

Getting the heat to your dorm

April 12, 2008

Q.  Are Williams steam lines “leaky” causing us to waste energy? 

Williams central heating system, comprised of the co-generation heating plant and underground steam lines, is a very efficient part of our campus utility infrastructure.

The heating plant operates at 83% efficiency, meaning that for every BTU (british thermal unit)  of energy input, 0.83 BTUs of high pressure steam are generated. The high pressure steam then runs through a turbine to generate electricity.  About 5,000,000 kWh of electricity are produced during the winter months, in addition to the steam heat produced.   Once the steam leaves the plant, it travels through steam tunnels to reach our campus buildings.

Converting steam to building heat: In the buildings the steam then travels through coils in heat exchangers to transfer the energy from the steam to water that subsequently circulates throughout the buildings.  As the steam loses heat in the exchangers it condenses and returns to liquid state. 

One way to evaluate the efficacy of this system is to determine the amount of condensate, condensed steam, that comes back to the heating plant.   At Williams, we recover about 92% of the steam that has been sent out through the system. Therefore, we only have to “make up” or add about 8% water to the system.   As a point of reference, EPA noted a steam improvement project in a large specialty plant that reduced its boiler make up water rate from 35% to 14-20%. Currently Williams is operating at a much better rate.

Melting snow: You may notice in a couple of spots on campus that the snow melts first where there are steam lines buried underground. While this does indicate that the ground is a little warmer in those areas, it is not an indication that the steam lines are leaking. Even well insulated steam lines will be warmer than typical ground temperature in the winter.   Our maintenance practises also ensure that our system operates at maximum efficiency.   Much of the steam system is housed in tunnels large enough for our maintenance personnel to enter.  

Keeping things working: Several times per year, we go through the tunnels to ensure that steam traps are not leaking and that insulation is adequate and performing well. Insulated steam lines should not be too hot to touch by hand.  At the steam plant, we evaluate both the amount of condensate returned, we do this by measuring the amount of ‘make-up’ water we need to add to the boilers, as mentioned earlier; and the hardness of the water.  

The hardness of the water can indicate that some of the municipal water has entered the system.   Hard water has a high mineral content usually due to dissolved calcium (Ca2+) or magnesium (Mg2+) .   Whenever we detect elevated levels of water hardness our maintenance personnel are dispatched to determine the source of this infiltration and correct the problem.  We have a regular program of repairing and up-grading our steam line and related infrastructure in order to maintain high performance levels.  

All of this work helps minimize the amount of energy necessary to keep our buildings at a comfortable temperature during the cold winter months.

Q2. Local fruit in dining halls

March 10, 2008

Q: I’ve noticed the increasing emphasis on locally produced dairy in the dining halls. Is there a similar effort underway to increase the availability of local fruit?

 According to director Robert Volpi, Williams Dining Services is currently making significant efforts to, when possible, use organic and locally produced food products. Through their own efforts and the facilitation of Ginsburg Food Distributors, Volpi and his team have brought an increasing number of locally produced foods into the dining halls in recent years. The five dining halls on campus now carry between 12-15% local products, as well as an abundance of fair trade and organic foods. Because of cost and logistical restraints, though, it is not possible to exclusively carry food that is up to these high standards. According to Volpi, in addition to purchasing local, organic, and fair-trade, Williams Dining Services is making significant efforts to support American farmers by ordering domestically. Thus, while not all food can come from the beautiful Berkshires, we can at least ensure that it comes from sources within the country.

Despite such logistical constraints, Williams is making a statement by purchasing their apples, pears, plums, strawberries, blueberries, raspberries, and melons from local farmers. Between sources such as David’s Melons and the Apple Barn, Dining Services has been able to buy local, while still maintaining a high quality of service and a balanced budget. Last academic year alone, Williams purchased over $28,000 worth of apples from local organic sources. All of this local fruit is either delivered directly to the dining halls, or to the brand new flash-freezer in the basement of the Paresky Center. This innovative freezing process allows Dining Services to naturally preserve seasonal local fruit, and serve it at the dining halls year-roun.

Overall, though Williams Dining Services faces budgetary and logistical restraints, they are taking enormous strides toward providing the College with locally produced products. With a large portion of the fruit already local, Volpi and his team are now moving toward making the rest organic and domestic.

Zilkha Center Logo

March 3, 2008

The recently established Zilkha Center for Environmental Initiatives is working on developing a logo. It is our aim that the logo be used to identify environmental initiatives across campus, whether they be related to sustainable food initiatives, energy conservation, renewable energy, green building practices, education, waste reduction among others.

The Zilkha Center for Environmental Initiatives, launched in December 2007, was established with the generous support of a Williams alum and is intended to work with students, faculty, and staff to incorporate principles of sustainability into the fabric of campus life — in learning, in our purchasing and operations, in capital projects, and in the daily routines of us all. It will lead the development and management of a strategic plan for sustainability to include energy management and greenhouse gas emissions reductions, waste management, environment-friendly development and purchasing, and student involvement and education.

Please let us know what you think of the logo options we have developed!
