None
A brief description of when and why the building energy consumption baseline was adopted:
It is also when the baseline year for the Greenhouse Gas Emissions was adopted.
None
A brief description of any building temperature standards employed by the institution:
Vassar’s Energy policy specifies temperature set-points during a 24 hour period based on expected occupancy and use of all buildings. Temperatures are also adjusted based on measurements of outdoor temperature, and are computer controlled for each building.
None
A brief description of any light emitting diode (LED) lighting employed by the institution:
Vassar’s Buildings and Grounds shop, the Fergusson Quadrangle (an outdoor space), and the main dining hall are illuminated entirely by LED lighting (about 450 bulbs).
Plans are being finalized to install LED lighting in the Lehman Loeb Art Museum (250 bulbs), the Palmer art gallery (50 bulbs) and our campus outdoor lighting (500 bulbs).
None
A brief description of any occupancy and/or vacancy sensors employed by the institution:
Vassar uses lighting sensors in many classrooms across campus. Buildings that have lighting sensors throughout include the Library (combined infra-red and motion detectors), Walker Field House (based on occupancy), Kenyon Hall (motion detectors) and Davison dormitory (motion detectors).
