Oakland Schools 2014/2015 Energy Report January 31, 2016

ANALYSIS  CONSUMPTION  Total electrical consumption is down 1% compared to the previous year and is equal to the ten (10) year average.  Total natural gas consumption is down 2.7% compared to the previous year but is 13.5% higher than the ten (10) year average.  Combined natural gas and electricity total BTU consumption per square foot decreased 6.03% but is 10.19% below the ten (10) year average.  UTILITY RATES (Generation and Distribution)  Average “all in” electricity rates paid by OS increased from 7.65 cents per kilowatt hour (KwH) in 2014 to 7.91 cents per KwH in 2015 for primary service. Secondary service decreased from cents per KwH in 2014 to 10.7 cents per KwH in  Average “all in” natural gas rates paid by OS decreased from $8.63 per thousand cubic feet (McF) in 2014 to $6.77 per McF in  ANNUAL COSTS  The total annual cost for electricity and natural gas combined is down $78,429 or 7.64% less than the prior year, a decrease from $1,026,458 to $948,029.  Cost per sq. ft. is 7.84% higher than the previous year but is 3.73% lower per sq. ft. than the ten (10) year average. Total energy costs organization-wide are down 16.63% or $189,053 lower than ten (10) year average. 2

ANALYSIS cont.  CLIMATE  According to the National Oceanographic and Atmospheric Administration (NOAA)'s Climate Center, 2015 was the warmest year on our planet in more than a century of record keeping and they expect 2016 to be even warmer.  According to the Farmers Almanac, 2016 winter weather will be colder than normal with below normal precipitation. Summer will be hotter and slightly drier than normal with the hottest periods in late June and mid to late August.  CONCLUSION  Increases in natural gas and electricity consumption are mostly weather related with the exception of the Summit Campus. It is believed that the increases in the Summit Campus utility consumption are from neighboring suites tied into Oakland Schools metered utility lines. Oakland Schools Legal Department is working on this issue. 3

Ongoing Energy Cost Saving Measures Monitor utility usage and frequently check HVAC 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, turning off refrigeration units during summer months. Study utility market pricing to lock in contract rates when favorable. Continued lighting control and LED bulb/fixture improvements. HVAC energy saving updates for all buildings as the need arises (i.e. new high efficiency administration building boiler). Building temperatures continually monitored at all locations per Board policy. Track down unnecessary appliance use (heaters, fans, refrigerators, etc.). On-going energy savings awareness program at all buildings. Upcoming Projects DTE re-commissioning of HVAC system and building envelope. Upgrade Metasys HVAC control system to provide reliable access. Recover utility charges related to the Summit campus metering issue. 8
