| Baseline period | July 1, 2004 | June 30, 2005 |
A brief description of when and why the 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.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0.10 MMBtu per square foot | 0.15 MMBtu per square foot |
| Baseline year | 0.12 MMBtu per square foot | 0.21 MMBtu per square foot |
Percentage reduction in total source energy consumption per unit of floor area from baseline:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
A brief description of energy use standards and controls 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. https://denison.edu/forms/energy-occupant-use-standards
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Denison has replaced 95% of campus lighting with LEDs.
A brief description of passive solar heating, geothermal systems, and related strategies 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 co-generation employed by the institution:
N/A
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
As a matter of course, Denison replaces appliances with Energy Star rated ones. As buildings are renovated, Denison utilizes its Green Revolving Loan fund to ensure high efficiency systems and technology are deployed.
