14 14 Observations (cont.) Covered or Blocked Unit Ventilators

15 15 Observations (cont.) Lack of Knowledge

16 16 How Schools are Typically Operated Without knowledge of energy use and impact of individuals actions No uniform energy policy No approved Energy Management Plan Limited preventive maintenance Lack of total involvement of personnel All impact performance – energy efficiency

17 17 Energy Management Best Practices Utility Management – need to know how much you use before you can determine how much you can save ENERGY STAR Portfolio Manager – Baseline Review and approve utility bills Energy use audit of each facility Building occupancy profiles Building characteristic and systems

18 18 Energy Management Best Practices (cont.) Understanding of EMCS System Develop and obtain approval of energy policy Develop an energy regulation Develop an energy management plan

19 19 Energy Management Best Practices (cont.) Develop and obtain approval of an Energy Policy— foundation for EMP –Short document – 3 or 4 short paragraphs –Include a statement of purpose “.. Provide leadership in developing a realistic energy ethic in the operations of our facilities ……. Success is the joint responsibility of governing body, administrators, teachers, students and all organization personnel and is based on their cooperation….” –Policy should include “… Superintendent is responsible to implement …. and administrators will be evaluated on the success …..”

20 20 Energy Management Best Practices (cont.) Regulation to Implement Policy –Regulations can state specifics about the operations of energy systems in your buildings –Regulation can establish accountability –Regulation can include the establishment of Energy Manager Position and a Energy Mgt Team –Establishment of an incentive program –Establishment of a reporting and evaluation system

21 21 Energy Management Best Practices (cont.) Development of an EMP –Statement of Purpose “…Guide the operation of the agency to achieve the highest standards in energy/water use/environmental and economic performance…” –State goals – “… X percent reduction in energy use for each facility by the FY 20xx –20yy..” Can be in several areas including training and education –Sets objectives to achieve each goal

22 22 Opportunities and Strategies Commissioning of Building Systems Lighting Plug Loads Phantom Loads HVAC Energy Efficient Transformers Buildings as a Teaching Tool

23 23 Opportunities and Strategies (cont.) Commissioning of Building Systems Re-Commissioning can provide an opportunity to tune-up your building Retro-Commission a building that has not been commissioned

24 24 Opportunities and Strategies (cont.) Lighting Control hallway lights in segments with multiple switches Use sensors to automatically dim lights when natural light is present Install motion detectors with manual override to cut lights in unoccupied hallways and seldom-used rooms Use compact fluorescent light bulbs in storage closets Clean lamp lenses Upgrade lamps—New lamps produce more light so fewer are needed

25 25 Opportunities and Strategies (cont.) Lighting Don’t over-do classroom lighting –Most designed over 70+FC –50FC recommended Install separate switches for lights near windows and for lights near interior walls Install motion detectors to cut lights in unused classrooms Control top outlet of a duplex outlet with occupancy sensor Separate switches for task lights and room lights

26 26 Opportunities and Strategies (cont.) Lighting Use fluorescent outdoor lights If school has security system – turn off all interior lighting minutes after being set –Exterior lighting (current) – turn off completely –Exterior lighting (new tech) – sector/motion –Potential energy savings – 10-15%

27 27 Opportunities and Strategies (cont.) Plug Loads Educational devices or appliances plugged into a school’s electrical system—Up to 25% 120/208 volt electrical systems Examples in schools: copiers, refrigerators, pop machines, microwaves Examples in the classroom: computers, TV’s, DVD players, tape players, boom box, radios, CD players, printers, scanners, copiers, fish tanks, mini-refrigerators, toasters, coffee pots, hot plates, overhead projectors, LCD projectors

28 28 Opportunities and Strategies (cont.) Plug Loads Vending Machines Install vending misers on soft drink and snack machines Remove internal lighting 50% energy savings Computers –Turn off computer monitors when not in use –Install energy-saving screen savers –Purchase new ENERGY STAR computers

29 29 Opportunities and Strategies (cont.) Phantom Loads Also known as “Stand-by Power” and “Leaking Power” Phantom loads exist in equipment with electronic clocks or timers, with remote controls, portable equipment and equipment with wall cubes This equipment can consume energy from 3 to 25 watts per hour when turned off Wall cubes big “phantoms” Up to 5%

30 30 Opportunities and Strategies (cont.) Phantom Loads Control plug and phantom loads by –Conducting a plug load survey –Education –Energy awareness training –Developing energy guidelines for plug loads Include fees for personal items Have “teeth” in the guidelines

31 31 Opportunities and Strategies (cont.) HVAC Systems Install an energy-efficient HVAC system Size HVAC system appropriate to square footage and design Control outside air Control unit operation Conduct preventive maintenance Change filters Site heat producing equipment away from thermostats Don’t block vents or use unit ventilators as shelves

32 32 Opportunities and Strategies (cont.) Energy Efficient Transformers Currently, out of sight and out of mind—Today a “Dark Hole for Energy Inefficiency” in all building types Energy Being Lost Behind Closed Doors Energy Efficient Transformers A “Gold Mine” for efficiency and cost reductions

33 33 Opportunities and Strategies (cont.) Energy Efficient Transformers A DOE study * found that: –Aging infrastructure and lightly loaded transformers –60-80 Billion kWh losses annually 40+ Million in commercial buildings –Installing energy efficient transformers can save the equivalent of 9 days of electric power generation * Federal Register – Part II Department of Energy, EERE, 10 CFR Part 430, Energy Conservation Program for Commercial and Industrial Equipment : Energy Conservation Standards for Distribution Transformers, July 29, 2004.

34 34 Opportunities and Strategies (cont.) Potential Energy Savings –Use of lighting systems – 30-40% of classroom lighting –Lighting controls – 10% –Type of lighting –HVAC – up to 20% –Plug loads – 25%+ of current plug load –Phantom loads – 50% of up to 5%

35 35 Opportunities and Strategies (cont.) Buildings as a Teaching Tool Students, Administration, Community Increases energy awareness Have it interactive –Twenhofel Middle School, KY Provides hands on experiences Translate technologies and building features to everyday life
