Baseline Year July 1, 2012 June 30, 2013

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):


Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 6,237,005 Gross square feet 6,118,203 Gross square feet

Source-site ratio for grid-purchased electricity:

Total building energy consumption per unit of floor area:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):

Central Michigan University is invested in the behavioral changes of staff, faculty, students and guests. Education and outreach is an effective way to kick start these changes. CMU's Facilities Management team has been working on several behavior modification programs, designed to enhance sustainable efforts on CMU.

Central Michigan University launched a campaign to reduce the use of light's in areas with inconsistent use. In every room, within CMU's institutional boundaries that have individual-controlled lighting options (i.e. a light switch), CMU has places a bright green sticker on the light switch fixture. These stickers read, "Please turn this light off as you leave." These stickers, though seemingly simple, have made a quantifiable difference in energy usage at the University.

Campaigns such as the afore mentioned, have started to change the culture and overall behavior of individuals all over campus. Social norms now dictate that the sustainable thing to do, when leaving a location that one has control over the lighting, is also the correct and normal thing to do. This shift continues to bring energy usage at Central Michigan University into a more efficient age.

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

Central Michigan University has made an immense shift in the past decade towards energy efficient building spaces. One of the large projects that has swept across the institutional boundary is the shift from traditional light fixtures to occupancy/vacancy sensing fixtures. These newer fixtures are motion-censored and are capable of detecting when there are occupants near by. As a result, large indoor areas are able to be lit when in use and conserve energy by remaining dark throughout periods of dormancy.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

Central Michigan University has switched virtually ALL lighting on campus from traditional lighting to energy efficient lamps. This switch to energy efficient lamps saves the University essential money, due to lowered energy bills, as well as drastically reduces the amount of energy used on a day-to-day basis.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
