Oakland Schools 2010/2011 Energy Report October 28, 2011

SUMMARY CONSUMPTION  Total electrical consumption is down 3.83% as compared to the previous year.  Total natural gas consumption is up 2.46% as compared to the previous year.  For both natural gas and electricity, the total BTU consumption per square foot has increased 2.69% but is 26.9% below the 2009 level and 40% lower than the consumption rate per sq. ft. in 2005 CLIMATE  According to the National Oceanographic and Atmospheric Administration (NOAA)'s Climate Center, Southern Lower Michigan’s winter was mostly cooler than normal with above normal snowfall. UTILITY RATES (Generation and Distribution)  The electrical rates increased, from 9.20 to cents per kilowatt hour (KwH) for primary service and increased, from to cents per kilowatt hour for secondary service.  Natural gas prices decreased, from $9.54 per McF in 2010 to $8.27 per McF in ANNUAL COSTS  The total annual cost for both electricity and natural gas is down $60,343 or 5.6% under the prior year (a decrease from $1,077,670 to $1,017,330). The resulting savings is due to: cost saving energy improvements at the campuses and the administration building continued strict enforcement of the energy policy rate decreases from buying utilities on the open market  Cost per sq. ft. is 39% lower than the cost per sq. ft. in 2006 and total energy “cost” organization wide are 24.6% or $374,170 lower than in

Ongoing Energy Cost Saving Measures Continued monitoring of utility usage and frequent checking of controls to ensure systems are operating efficiently. Examples include night set back of temperatures, run times on equipment, adjustment of timers for parking lot lighting, and turning off refrigeration units during summer months. Continued monitoring of utility market pricing and locking in contract rates when favorable. Continued elimination of night lighting at all buildings. HVAC Energy Saving Measures continuing for all buildings. Building temperatures increased in the summer and reduced in the winter and continually being monitored at all buildings per Board policy. Replacing older fixtures with more energy efficient fixtures. Unnecessary appliances removed (heaters, fans, refrigerators, etc.). Implementation of energy savings awareness program at campuses. Addition of alternative energy sources at all buildings. 7
