In the United States, buildings account for nearly 70 percent of electricity consumption and 40% of energy use of all types. Buildings are responsible for almost 40% of the country's carbon dioxide emissions. The Fermilab site includes more than 100 buildings greater than 5000 square feet. Federal Executive Order 13514 mandates that eventually buildings in this size class must comply with the Guiding Principles for Sustainable Buildings. Fermilab has a goal of improving 15 of 100 existing buildings to meet the Guiding Principles.
There is an effort to ensure that all new buildings at Fermilab are sustainable by designing them to the Guiding Principles for New Construction. Buildings are designed to be energy efficient, conserve resources, and provide comfortable and healthy environments for occupants. The Illinois Accelerator Research Center's Office, Technology and Education Building is designed to meet one of the highest LEED standards. Construction was begun on this 47,000 square foot building in June of 2012.
