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

2005 was adopted as our baseline year because it represents the baseline we used when signing the Presidents' Climate Commitment. It also represents a year where we know we have accurate and complete GHG data.

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

The Energy Management System (EMS) has timers integrated within it that cover many of the building spaces on campus. There are also a number of stand-alone timers, however, few are used because the EMS is used instead.

Denison has a occupancy use standard that includes temperature set-points and set-backs when spaces are occupied and unoccupied.

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

LED lighting is being tested all around campus. We use it in one of our main reception halls for major events. LEDs are in many of our outdoor lighting features.

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

Multiple buildings on campus have motion-sensing light fixtures. Many bathrooms are also equipped with this technology. Light sensors are used in a few areas that automatically turn off or dim lights based on ambient lighting.

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

Many of our newer buildings including those constructed at the Denison Homestead utilize passive solar designs to reduce heating costs and to take advantage of day light.

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

The Polly Anderson Field Station at our 350 acre biological reserve utilizes ground-source heat pumps for its HVAC system.

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:

The EMS system covers 1,424,015 square feet of building space, roughly 80.6% of all occupied building space on campus. The system provides external monitoring and control over energy consumption. All buildings are sub metered for electricity and water.

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

Our purchasing guidelines require that Energy Star products be purchased when available.

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:

Several vending machines on campus now have motion-sensing technology that turns light for the vending machine on when a person is standing in front of the machine.

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