replaced. Plexiglass curtains were installed in residential restaurant food preparation areas to focus the amount of air flow to ventilation hoods from cooking areas and reduce air flow from dining areas. Information Technology has implemented a pilot green computing program using software to remotely shut down computer equipment when not in use. The original pilot program included all six colleges, ProfEd, Office of Information Technology, and Auxiliary Services. The pilot resulted in net energy savings of approximately $50,000 annually. Extension of this program to the entire campus would conservatively result in $200,000 in energy savings each year. CMU also takes advantage of the program provided by Apple Inc. to recycle e-waste for those electronic components that cannot be resold as surplus or sold at auction. CRT monitors are being replaced as resources permit with more efficient LCD monitors. Digital imaging systems are already in place in Financial Aid and Payroll Accounting and are being added to other areas such as University Admissions. These energy conservation measures have resulted in a 12% overall reduction in energy use per gross square foot of building space from the FY 2007 baseline. Approximately 2,000,000 kWh of electricity is being saved annually due to these improvements. The following charts from FM illustrate these reductions. Total purchased electricity was reduced by 5.7% from FY 2007 (baseline year) to FY 2010. This reduction of 3,807,376 kWh equates to cost savings of approximately $266,500 at our discounted purchase rate from the electric cooperative of $0.07 per kWh. At the Central Energy Facility, a combustion air pre-heater was installed on the wood boiler combustion system. The facility continues to use waste wood chips from Michigan’s forest product industry in its electric/steam co-generation system. A steam absorption chiller was refurbished to offset the operation of an electric chiller, which is expected to generate $584,000 in purchased energy cost savings per year. FM is also securing all available energy rebates from our energy suppliers. Thus far, rebates are totaling $45,049.
