A brief description of when and why the building energy consumption baseline was adopted:

Fiscal year 2012 is used as the baseline because that is the first reporting period following the college's conversion of #6 fuel oil to a mix of #2 fuel oil and propane gas.


A brief description of any building temperature standards employed by the institution:

Where possible, temperature set-backs and set-points are used. Typically, a set point range around 68-70 degrees during heating period is employed and building systems, where these are adjustable, strive to achieve room temperatures within this set point range. Few buildings on campus are air conditioned but for those that are, summer a/c set points around 74-76 degree are employed.


A brief description of any light emitting diode (LED) lighting employed by the institution:

All screw-in incandescent light bulbs were upgraded to LED lighting. The gym recently was upgraded and lighting upgraded to LEDs as well.


A brief description of any occupancy and/or vacancy sensors employed by the institution:

Occupancy sensors are installed on many public space light switches, including bathrooms in Macmillan Hall and Long Library and bathrooms, classrooms and hallway lighting in Zabriskie Hall.


A brief description of any passive solar heating employed by the institution:

Stratton Hall has south and west facing windows into the central atrium area so is able to employ some solar heat gain of the cement floor in that atrium area.


A brief description of any ground-source heat pumps employed by the institution:

none


A brief description of any cogeneration technologies employed by the institution:

none


A brief description of any building recommissioning or retrofit program employed by the institution:

none


A brief description of any energy metering and management systems employed by the institution:

Electricity submeters are in use on several campus buildings: Stratton Hall, Weld, Dodge, Long Library, Macmillan. We don't currently have an energy management system in place but are uploading monthly meter readings made manually by Facilities staff into EPA's Portfolio Manager to track changes.


A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:

Wells regularly upgrades equipment to EnergyStar standards, where this certification applies. Information Technology group, which purchases computer and AV equipment for the campus, utilizes the EPEAT standard, which incorporates EnergyStar standards.


A brief description of any energy-efficient landscape design initiatives employed by the institution:

Any hard scaping and sidewalks around most buildings are kept light-colored, so as to reflect light and reduce heat island effect.


A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:

Our new contract for vending machines (to start summer 2016) was bid to include EnergyStar TierII compliant cold beverage vending machines. This new equipment will also be retrofitted to feature LED lighting and sensors. Where appropriate, even with LED lighting, if room ambient lighting is sufficient to see the available product, we will request no interior lighting in both cold beverage units and snack machines.


A brief description of other energy conservation and efficiency initiatives employed by the institution:

A significant component of the community outreach campaign related to sustainability involves engaging the campus community in energy conservation (turning off light switches, engaging sleep settings on computers, turning off monitors, reducing water use, etc.).
