Summary: These guidelines were approved in June 2011 by the Williams College Board of Trustees.
In 1991, the College's physical plant measured 1.9 million square feet; by 2007 it had grown
about 24% to 2.4 million square feet. At the same time, its energy use per square foot increased
20%. The student population stayed roughly constant but the number of faculty and staff
increased from 750 to 990 full-time equivalents.
The result of these trends was a 40% rise in greenhouse gas emissions.
In January 2007, the Board of Trustees approved the College's goal to reduce greenhouse gas
emissions associated with campus operations to 10% below 1990/91 levels by 2020 and the
adoption of environmental sustainability as a guiding college principle.
Since January 2007, concerted efforts have significantly reduced building-related energy use and
greenhouse gas emissions. The College has invested in energy conservation projects, electricity
and steam metering systems, installed photovoltaic panels on the Library Shelving facility,
improved control systems and operating practices, and changed to cleaner sources of fossil fuels.
It also is working toward LEED certifying new building projects and adopted energy modeling,
building systems commissioning, recycled waste management, and other sustainable design
practices. To continue to make progress, Williams must continue to find ways to reduce energy
use and to ensure that new building and renovation projects support emissions reduction goals.
