Campus Night Audits
For several years, the Sustainability Office assessed off-hours energy use in campus buildings to understand the potential savings from advocating that building occupants turn off lights and other equipment, close shades and windows, and take other actions. As part of various academic class projects, students worked with Sustainability Office team members to perform unannounced night audits several times each quarter. During a night audit, buildings were thoroughly examined during predominantly unoccupied times to find potential energy waste.
Audits measured losses from unnecessarily active electrical equipment like lighting, computers and peripherals, copiers, printers, and chargers, as well as thermal losses like open windows. Losses were totaled and potential savings estimated. Data gathered during the audits can be used to assess the impact of conservation efforts, justify additional conservation projects, as well as report potentially unsafe conditions (low light levels, fire hazards, etc.). A summary of night audit results is presented in the table to the right.
