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

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

Yes, simple time clocks have been largely superseded. Equipment operation throughout campus is regulated by our Andover Continuum building automation system (BAS) which allows for complex clock routines and changes in schedule to accommodate the academic calendar. The system has approximately 8,500 control points. Among other functions, it is programmed to automatically reset temperature to save energy during unoccupied periods.When possible the system will shut down energy consuming equipment entirely when buildings are unoccupied. 90% of campus buildings are under the control of the campus BAS.

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

Yes, LED lighting is being used extensively in exit signs throughout campus. We are currently in a program of replacing halogen PAR lamps used in recessed fixtures with new LED lamps throughout campus in dining facilities, library, elevators, and other public spaces.

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

Motion, infrared, and/or light sensors are used throughout campus in classrooms, offices, hallways, and other public spaces. Exterior lighting is controlled by photocells. Athletic facility lighting can be staged to suit the particular function (ex., cleaning, free play, televised sports events).

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

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

President's residence has a single point deep well that serves 7 heat pumps within the building.
Residence Halls 5 & 6 have 8 each geothermal heat pumps (16 total) that provide heating and cooling to the students.

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

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

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

Our Andover Continuum Energy Management System tracks energy consumption and performance in multiple buildings over 1 Million sq ft in a central database/ control server. The system connects over 8,500 points and performs such conservation measures as Load Shedding, Staggered Startup, Outdoor Lighting control, Global Setpoints and Re-sets, Occupied Night Setback, Unoccupied Night Setback, Open Window Detection, Group Scheduling Overrides, Global Outdoor Sensors and Seasonal Control, Dual Loop Plants with Economizer Mode, Demand Based Ventilation sensing CO2 levels, Optimized Zone Occupancy Control.

The system provides user friendly Graphic Display of operating status and real time conditions allowing technicians to tune the system as well as diagnose equipment malfunctions.

The system monitors energy consumption by counting pulses generated by building and campus wide gas and electric meters. This information forms the basis of monthly and annual energy consumption data on a building-by-building level.

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

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

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

Support services has had our provider of vending machines change out their units with sensors and LED's.

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

LED light changeouts, CO2 monitoring in large meeting rooms/auditoriums
