Cabarrus County Schools Annual Energy Management Report 2015-2016

Current average efficiency is 44.39 KBTU/Square Foot

The spikes in water usage, Feb The spikes in water usage, Feb. 2012, came from a water leak at Jay Robinson.

Annual Summary ( 2015-2016- Baseline Year ) Red will indicate a rate increase This table is an attempt to compare this year’s utility usage and cost (2015-2016) to the baseline year’s utility usage and cost of each building. Keeping in mind that the baseline year for the new schools will be different from older CCSs. The baseline year used for most buildings is 2009-2010. The new buildings will be forced to use their first year of operation as their baseline year. Why use 2009-2010 as the baseline year? This was the beginning year for CCS’s Energy Conservation Program. Thus, using this year as a baseline will provide the performance of the program over the last four years. Cost Avoidance = $1,002,922.16 *Baseline year for most schools is 2009-2010 However, new schools will use their 1st year of operation as their baseline year.

Annual Summary (2015-2016/2014-2015) Comparing the last school year 2012-2013 to the previous school year 2011-2012 Cost Avoidance $329,009.02 Red will indicate a rate increase Cost Avoidance for (2015-2016) = $120,213.49

Annual Summary (2014-2015) Currently we are tracking the utility data from 39 buildings. In 2009-2010 we were tracking data from 37 buildings. Metric Tons of CO2 kept from the atmosphere = 41,829.66

Accomplishments When comparing 2015-2016 (July-June) data to the 2014-2015 data. CCS generated a cost avoidance of $1,006,327.06 for the district. Our energy usage has decreased over the past six years by 61,011,750.25 KBTU. Thus, keeping 41,829.66 metric tons of CO2 from the atmosphere. Average Efficiency (energy usage/sq. ft.) has dropped from 64.46 KBTU/Ft2 (2009-2010) to 42.54 KBTU/Ft2 (2015-2016). Over the last six years, when comparing the county buildings to their baseline data, they have provided a cost avoidance of 1,006,327.06 million dollars to the district. In the US, we account for 20% of the man made greenhouse gas emissions, with less than 5% of the world’s population.
