None
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.
None
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.
None
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.
None
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.
None
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.
None
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.
None
A brief description of any cogeneration technologies employed by the institution:
N/A
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:
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.
None
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.
None
A brief description of any energy-efficient landscape design initiatives employed by the institution:
---
None
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.
None
A brief description of other energy conservation and efficiency initiatives employed by the institution:
---
None
