Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):
kWh MMBtu
Imported electricity 45,849,000 Kilowatt-hours 156,436.79 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) 15,283 Kilowatt-hours 52.15 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):
MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy 973,159.73 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
1,129,648.66 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
6,118,203 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):
Start date End date
Baseline period July 1, 2009 June 30, 2010

A brief description of when and why the energy consumption baseline was adopted:
2012 marks the publication of a Sustainability is Central report, which indicates the initiation of new sustainable programs and systems across campus. Therefore, this is an ideal year for comparative measurements.

Source energy

Source-site ratio for imported electricity:
3.14

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.17 MMBtu per square foot 0.20 MMBtu per square foot
Baseline year 0.18 MMBtu per square foot 0.24 MMBtu per square foot

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:
15.22

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
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:
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:
Central Michigan University uses solar panels in order to supplement the heating and cooling systems. These are not quantitatively measured, but have a significant impact in reducing the cost of heating and cooling, as well as reducing the amount of non-renewable energy purchases. The solar panels are location on top of the Education and Human Services building, near the south end of campus.

A brief description of co-generation employed by the institution:
---

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Beginning as early as 2008, Central Michigan University began creating sustainability initiatives in order to reduce the universities environmental impact. These have included everything from sustainable purchasing guidelines, to water reduction systems, and even a 25% renewable energy purchasing rate.

Data source(s) and notes about the submission:
Central Michigan University has a significant environmental impact from the innovative usage of solar panels to replace non-renewables on sunny days. These data figures are not tracked, and therefore are not reflected in the STARS report.
