Tufts University has a long tradition of environmental and energy action. In 1990, Tufts was the first university to sign the EPA Green Lights pledge, a promise of upgrading lighting in 90% of our floor space. We have fulfilled this commitment.
People tend to forget shutting off lights. All over campus, many lights are left on accidentally at night and during weekends. In many class rooms, the wiring is such that light switches are not located near the doors but rather in front of the room which discourages shutting off of lights. Lights are also regularly left on in offices and bathrooms.
The potential energy and carbon savings of shutting off lights at nights and during weekends and term breaks are quite large.
In 2001, Tufts decided to invest heavily in these lighting upgrades. The following buildings were equipped with motion sensors and CFB.
|Campus||Building||kWh Savings||$ Saving||Payback in years|
|Medford||Cabot Hall of Flags||29,784||$2,978||0.9|
|Medford||Facilities (520 Boston Ave) -2nd floor||10,850||$1,085||2.6|
LEDs are very energy efficient. They have been used in several applications on Tufts campus:
The main parking garage located at 419 Boston Avenue was retrofitted with LED lighting in 2008. It was the first of its kind in Massachusetts.
The Brown and Brew, one of Medford campus’ cafe, was retrofitted with LED lighting in 2009.
LED lights were used as in long run hour locations in the renovation of the Facilities Services building (2011).
