Williams College
In 2007, Williams College committed to a goal of reducing its greenhouse gas emissions to 10% below 1990-1991 levels by 2020. Sebesta Blomberg developed a five-year master plan for campus energy and
greenhouse gas management. The scope included a full energy assessment of 20 facilities with
abbreviated scoping surveys of 60 buildings. The services included the integration of prior
retrocommissioning studies, thus the master plan encompassed the entire campus. Nearly 50 separate
areas of opportunity were identified, including operational enhancements, lighting conversions, controls upgrades and HVAC renovations. The master also addressed related longer term building issues,
including connection to central utilities, distribution piping, electric building heating and obsolete windows. Renewable energy options were also including in the master plan. Sebesta Blomberg assisted
with implementing the recommendations including detailed engineering, commissioning and savings
verification services.
