Some items you can turn off include office computers, copiers, and printers. Encourage coworkers to do the same. Adopt a last person out policy. The last person to leave labs, lecture rooms, and meeting rooms should be responsible for turning off unnecessary equipment and lights.
Fume hoods are a major source of energy consumption.
Laboratory workers should keep fume sashes at a minimum working height after setting up experiments and keep sashes closed when not in use. Turn off lights when they are not being used. Unoccupied offices, classrooms, conference rooms, and restrooms with lights on are opportunities for energy reduction. Turn these lights off as you leave the area. Possibly check these areas as you leave the office for the day, especially before weekends and holidays.
