5 Building Services Mission To provide excellent educational facilities for all stakeholders that are safe, clean, well maintained and environmentally secure CMS Energy Management Purpose is “to minimize CMS energy consumption, greenhouse gas emissions and utility expenditures through implementation of energy conservations measures throughout the district” Mission and Purpose

6 Strategic Plan 2014 Energy Management is the cornerstone to our Environmental Management System (EMS)

7 Key Strategies and Tactics Each focus area in Strategic Plan 2014: Teaching Our Way to the Top is supported by key strategies and tactics. Below are listed the key strategy and supporting tactics for Focus Area Five: Environmental Stewardship. Key Strategy 5.1.1: Engage all stakeholders in conservation of resources. Tactics: Engage students and staff in environmental stewardship Implement a district-wide Environmental Management System that follows the structure of ISO standards and passes a North Carolina equivalency audit Earn the following state-awarded designations: Rising Steward by 2011; Environmental Steward by Reduce electricity usage per square foot Reduce natural gas usage per square foot Reduce water usage per student Identify, pursue and secure supplemental alternative funding strategies for improving environmental performance measures Reduce total waste stream Reduce fuel consumption per mile for CMS fleet and equipment Reduce vehicle and equipment emissions Implement a sustainable-development program that uses high-performance standards for buildings Implement an environmentally sustainable purchasing program.

8 Reduced our KBTU/Sq. ft by 9.7% over the last 2 years (59.96 – 54.12). –This resulted in CMS being under our utility budget by over 2 million dollars for the last 2 school years

9 So how did we do it???

10 Do you have executive buy-in (either the superintendent and/or the Board)? I recommend following the energy star model as the federal government has put a lot of resources into the program that you can tap. Also the name recognition factor (free advertising) goes a long way. Most people know about the appliance side of energy star it is not a big leap to get them to the building side.

11 Energy Star Partner As of August 12 th we have 30 schools labeled totaling in excess of 3 million sq-ft. Received recognition as a Leader for 10 % Energy Reduction Energy Star Stats

12 CMS uses a software called utility manager pro to input all our utility information. 3 of our biggest providers provide electronic files of this information (no manual keying). CMS then uploads this information to Energy Star’s portfolio manager to obtain our rating. You cannot measure what you do not Track

13 Every month we look at several reports (print via PDF) –Usage report – year to date & Monthly Look for variances and inspect high users Budget reports –Track actual costs versus estimates Perform Measurement and Verification activities on maintenance projects –Why do this ??? You want to inform your staff that the work they are doing is making a difference (saving jobs, costs, etc…). Positive re-enforcement!

17 Since the Energy Management group is small CMS and budgets are tight uses other staff to aid in the efforts, these include: –Property Managers –Engineers –Maintenance staff –Custodial Staff –Energy Coordinators - Site base school staff –Students / Visitors also play a major role Staff

18 Each school has a designated coordinator They are responsible for receiving data and disseminating it to staff – monthly with links to data A lot of the reports we send compare school versus schools in the district. As you know most principals/schools are very competitive and if they are at the bottom – you can fill in the blank. Energy Coordinators

19 Property Managers serves as advocates for the Principals’ perform facility inspections and condition assessment, respond to emergencies, and help prioritize maintenance backlogs Energy Management instructs the property managers on what the data in the report means and answers any questions at the school house level. They also aid the Energy Management group in small projects that occur from time to time Property Managers

20 Things to do: –Ensure Schedules are working properly –Look at systems during non instruction time – nights and weekends – we found a lot of waste here – Systems running 24/7 that should not have been –Lights schedules – ensure they are not the same as HVAC schedules –Keep your sequences simple, complicated sequences tend to get over-rode by maintenance staff Energy Management Systems

21 Real time metering At many of our schools CMS has pulse meters and we are able to track real time consumption via our EMS systems. The graph to the left is of the Summer KWH use per day at our Military Magnet school. We were in 4 day work week mode and had our Summer Energy Management plan in place.

22 Energy Management Systems Simple Strategies (low costs/no cost) CMS has implemented simple energy strategies to eliminate re-heat when the outside air temperature is above 80 degrees Schedule Optimization After hours checking Due diligence and follow-up with maintenance staff, teachers, community use, etc…

23 All new schools have dual switching with in board / outboard control of lights (since about 2001). The last several years we have been installing a 3rd switch, row by the windows (day lighting). We have been installing photo eyes on atrium lights Converting T12 to T8 (bulbs and ballasts) Gyms we have started removing Metal Halide and going back with T5 fixtures or T8. Using rebates and grants to offset energy payback on the last 3 items. Lights

24 CMS is working with our curriculum department to integrate energy management and environmental stewardship into many programs –Program for 3 rd and 4 th graders with Duke Energy and Scholastic – Get energy smart –High Schools – many green clubs (as well as AP classes) and we have even funded several projects they proposed. –School incentive program Students

25 Poster Campaigns Signage Get the students involved (lights account for % of your electricity costs) Documents your successes and pass the word. Behavioral Change

26 Solar Hot water Projects in design Test pilot project going on with demand side management (very low demand charges less than $4.00). Goal to get our Energy Star portfolio to a 75 average – its currently at 65. Future for CMS
