A brief description of when and why the building energy consumption baseline was adopted:
Used in Babson College's Sustainability and Climate Action Plan that was submitted to the ACUPCC
None
A brief description of any building temperature standards employed by the institution:
---
None
A brief description of any light emitting diode (LED) lighting employed by the institution:
LED Lights have been used in 2 classroom applications and an office in our Facilities Building. We have also used LED's in the majority of our outdoor lights and we have five solar powered lights that have LED's in them. LED lights are being experimented with for use in elevators and some elevator lobbies.The college recently installed LED lighting in a major parking lot at the college skating rink and a main Student Lot (Knight Lot). We have utilized high efficiency induction lighting in our parking deck. We have installed LEDs in our Campus Center.
None
A brief description of any occupancy and/or vacancy sensors employed by the institution:
70-80% of our non residential buildings have occupancy control. These sensors have been used in several residential buildings. We have offices in our facilities building with motion sensors, classrooms with motion sensors and residence halls where hallways and common spaces have motion sensors. Technologies include passive infrared and acoustic motion sensors. Lights over library stacks are controlled by rows.
