    1. Managing Energy Cost in Challenging Times Innovative one-stop service energy programs with the latest technology advances and special negotiated utility rebates a report from Energy Efficiency Group Tomorrow’s Energy Technologies Today www.energyefficiencygroup.net

    2. Roadmap to further cut energy cost If you have a mandate to further reduce costs … and you’ve already done most all you can to cut costs, what is possible? Generally save 10%-30% more with “latest” technologies Generally qualify for rebates up to 70% of project cost Enjoy 25% to 50% R.O.I. Recover investment from savings in 12 to 36 months Complete projects with no cash outlay www.energyefficiencygroup.net 2

    3. Electric demand is rising - prices follow demand Department of Energy data www.energyefficiencygroup.net 3

    4. The strategy to materially cut electricity costs Department of Energy report depicting impact of taking advantage of the “best available technology” to cut cost. www.energyefficiencygroup.net 4

    5. What savings is realistically attainable Added savings of 8% to 12% for facilities already highly efficient Savings of 25% to 50% for facilities not yet energy efficient HVAC…save to 50% with compressor and controls, CO and CO2 sensors, EMS, and HVAC ultraviolet systems LIGHTING …save to 70% for buildings, garages, and street lights with latest fluorescent, LED, and induction lighting, and controls www.energyefficiencygroup.net 5

    6. — CB Richard Ellis "Your program not only produced rebates, but it led to many projects that otherwise wouldn't have happened. You helped us quantify the opportunities and then guided us through to their completion…..." www.energyefficiencygroup.net 6

    7. –– Trammell Crow Company "We consider this a unique approach to utilize our relationships and infrastructure to benefit our clients and to significantly expand energy efficiency throughout our client base." www.energyefficiencygroup.net 7

    8. — California Energy Commission "The diversity of so many energy technologies was another added value. EEG's guidance led to participants taking a more comprehensive approach to energy efficiency … BOMA members engaged in a wide variety of energy projects that reduced peak period demand by 17,000 kilowatts." www.energyefficiencygroup.net 8

    12. HVAC ultraviolet (UVC) emitter technology Installs at A/C coil to cut energy cost, improve IAQ, eliminate coil cleaning Florida Hospital emitters enhance IAQ and infection control, save maintenance and downtime. The substantial energy savings are a great bonus. — Florida Hospital, Orlando, Florida www.energyefficiencygroup.net 12

    13. HVAC ultraviolet (UVC) emitter technology UVC cleans dirty coils and restores like-new performance We have eliminated our four-time per-year coil cleaning program and estimate a conservative 28% drop in A/C system energy usage. — American Electric Power, Dallas, Texas www.energyefficiencygroup.net 13

    14. HVAC ultraviolet (UVC) emitter technology Microscopic amounts of coil fouling significantly reduce efficiency 1. All A/C attracts mold and fouls coils. 2. Cleaning only removes surface fouling. 3. Coil fouling reduces heat transfer and air flow. www.energyefficiencygroup.net 14

    15. HVAC ultraviolet (UVC) emitter technology UVC cleans coils and greatly improves indoor air quality Coil fouling is demonstrated with samples taken from coils. Installed in coil plenum, UVC eradicates bacteria and mold. — Air Conditioning/ Heating/ Refrigeration News www.energyefficiencygroup.net 15

    16. HVAC ultraviolet (UVC) emitter technology Stop the spread of infectious disease through A/C delivery system UV disinfection works by penetrating cell walls of pathogenic organisms and structurally altering DNA, thus preventing cell replication. — U.S Environmental Protection Agency www.energyefficiencygroup.net 16

    17. Ventilation control CO2 sensor technology Elimination of excess outside air ventilation for major energy savings The City of Seattle has standardized on the AirTest CO2 sensor… although there was significant savings on cooling cost, the big savings was on heating costs. — Seattle City Light www.energyefficiencygroup.net 17

    18. Ventilation control CO2 sensor technology Elimination of excess outside air ventilation can save up to 20% The cost for heating or cooling of excessive outside air for building ventilation can be up to 20% of HVAC cost. There are occupancy variations and excess ventilation over design in most buildings. www.energyefficiencygroup.net 18

    19. CO2 sensors for demand control ventilation Building air intakes are not measured and the delivery of outside air is not controlled, generally resulting in significant over-ventilation. Most buildings are over-ventilated 200% to 400% in excess of actual need., especially those with significant occupancy swings . CO2 system determines real-time occupancy throughout the building and adjusts outside air to match the need and cut HVAC cost 5- 20%. www.energyefficiencygroup.net 19

    20. Garage fan CO sensor and VFD system Latest advance in electrochemical sensor technology Fan run time reduced from 24 hours to about 45 minutes per day – over 90% reduction with a simple payback of 18 months. — CB Richard Ellis, Westwood Plaza www.energyefficiencygroup.net 20

    21. Garage fan CO sensor and VFD system Garage fan run time reduced by 90% at Trident Center Total demand reduced from 67 kW before installation to 7 kW after installation, for a reduction of 90%. The project had a simple payback of 12 months. — Trident Center Project Summary, California Energy Commission www.energyefficiencygroup.net 21

    22. Garage fan CO sensor and VFD system Fans typically run continuously when enclosed garages are open. Generally, CO level may require fans about 10% of the time. CO sensors operate fans only when necessary to keep CO from reaching unhealthful levels to produce typical 80% to 90% savings. VFDs on fans maintain constant base level of ventilation and only increase fans to levels necessary if CO is present. www.energyefficiencygroup.net 22

    23. Oil-free refrigerant compressor technology Turbocor oil-free compressor retrofit reducing HVAC costs to 70% This revolutionary technology provides efficiencies up to 30% better than any other compressor in its size range in addition to being extraordinarily quiet and virtually vibration free. — 2003 AHR Expo Innovation Awards www.energyefficiencygroup.net 23

    24. Oil-free refrigerant compressor technology Oil-free compressor with VFD and magnetic bearings Based on test results, 30-40% energy savings over reciprocating air-cooled compressor technologies are realistic. — San Diego Regional Energy Office www.energyefficiencygroup.net 24

    25. The Turbocor compressor at a glance www.energyefficiencygroup.net 25

    26. Redefining the compressor www.energyefficiencygroup.net 26

    27. Whether it’s 60 to 120 tons www.energyefficiencygroup.net 27

    28. Or 720 tons - - - Turbocor starts on less than 2 amps www.energyefficiencygroup.net 28

    30. There was 12.88% average oil overcharge and 21% energy loss from 10 chillers tested In ten (10) chillers tested in the ASHRAE study, average oil system overcharge was 12.88%, for average 21% energy loss. www.energyefficiencygroup.net 30

    32. Solar protection window film options Visibly clear film reduces solar heat to 50% without changing building appearance Tinted films reduce solar heat 50% to 80% and reduce glare Reflective films reduce solar heat 80% Graffiti protection film protects windows from vandals Security film protects against shattering www.energyefficiencygroup.net 32

    33. Solar protection window film reduces heat and U.V. Infrared heat and U.V. rays increase air conditioning cost, create discomfort, and cause fading. Visually clear, tinted or reflective solar protection film can reduce up to 80% of solar heat and block up to 99% of U.V. rays. www.energyefficiencygroup.net 33

    34. Action Steps Determine big picture of “what is possible” energy savings and return-on-investment targets Complete detailed assessment of facilities, develop and evaluate energy savings options, and economic analysis Develop Opportunity Report of action and economics for one-stop, concept through completion energy strategy www.energyefficiencygroup.net 34
