Overnight Lighting

In January 2009 the Sustainability Director began an informal assessment of campus lighting levels at BU, initially to benchmark where lights were being left on at night, then to observe what progress was being made to reduce that percentage.

As illustrated in the maps below, the ongoing campaign is proving successful. Much of this can be attributed to greater awareness of the need to reduce energy consumption, and the efforts of the University’s custodial staff to turn lights off during their rounds at night.

In November 2009, ten months later,  the Sustainability Director again conducted assessments to benchmark progress to date, and to establish the lighting levels before the Sustainability Liaison program launched. In coordination with the Director of Custodial Services, who provided the January 2009 assessments to the Area Directors, the lighting levels further decreased between November 17th and 24th.  Our hope is that with the added efforts of individual school Sustainability Liaisons, the number of lights left on overnight will further diminish.

These assessments were conducted from the street between 5:30 and 6:30 am and exclude dorm rooms, lobbies, stairway, and hallways. Many of the areas remaining to be improved require system upgrades in improve controllability of the lighting.
