  4. Energy demand is rising and prices follow demand Department of Energy data illustrates increasing power demand. You will not offset future cost increases with conventional approaches. Delivered commercial energy consumption per capita - from DOE/EIA Annual Energy Outlook 2006 www.energyinnovation.net

  5. Only one strategy materially cuts your present costs Department of Energy data demonstrates that only with the best available technology can you significantly cut cost. Delivered commercial energy intensity (variation from reference case) - DOE/EIA Annual Energy Outlook 2006 www.energyinnovation.net

  6. What level of savings is realistically attainable • Additional energy savings of 8% to 12% are being achieved for facilities that are already highly efficient; • But savings can reach 25% to 30% for facilities that have not yet effectively engaged in energy efficiency. www.energyinnovation.net

  7. Savings potential of emerging technologies HVACRSAVINGS --- Save to 50% with compressor and controls advances, CO and CO2 sensors, wireless EMS, and ultraviolet UVC. LIGHTING SAVINGS --- Save 20 to 35% for buildings, garages, and street lighting with lighting controls. IMPROVED INDOOR AIR QUALITY --- Protect health with ultraviolet emitters to destroy DNA of virus, bacteria, mold. MAINTENANCE SAVINGS --– Eliminate A/C coil cleaning cost with UVC emitters to keep coils clean. www.energyinnovation.net

  8. — 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.energyinnovation.net

  9. –– 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.energyinnovation.net

  10. — Charles Dunn Real Estate Services"Your program and its personnel became an invaluable resource to us in identifying and implementing opportunities to reduce energy cost and receive very attractive rebates." www.energyinnovation.net

  11. — California Energy Commission"The diversity of so many energy technologies was another added value. EIG'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.energyinnovation.net

  12. Lighting power regulator technologyMicroprocessor-based lighting control connected to lighting panel saves 10%-30% on electronic fluorescent and HID lighting “We experienced an average 20.8% reduction of kW demand ..… lighting appearance and light levels were visibly unchanged.” – Cal/EPA Headquarters, Thomas Properties Group Power regulator, on the right, connected to lighting panel www.energyinnovation.net

  13. Lighting power regulator technology30% decrease in power consumption in parking garage The graph illustrates use of 29.17 kW with Globalight in ‘savings’ mode at the UCDMC Parking Garage. When taken out of savings mode, power use increases to 41.45 kW, demonstrating a 30% reduction of power in the ‘savings’ mode. Sacramento Municipal Utility District report on UC Davis Medical Center Graph showing: 1. Reduced wattage with Globalight in operation 2. Increased wattage with Globalight off-line www.energyinnovation.net

  14. Lighting power regulator technologyMajor savings for street lighting of typically 30% The City installed lighting power regulators to reduce the energy cost to operate its street lighting. SCE paid rebates based on the measured savings. – Redondo Beach, CA Power regulator connected to street lighting control panel www.energyinnovation.net

  15. Globalight voltage and current regulator The Technology and Improved Power and Lighting Quality • A toroidal transformer and control system slowly and smoothly reduces voltage and current from the power distribution system to lighting fixtures. • Design is matched to ballast type (s) and ballast factor, light levels, voltage, lighting system condition, manufacturer warranties and IES guidelines. • Globalight reduces harmonics, improves lamp current crest factor and provides proper lamp electrode temperature. • Lighting is visually unchanged due to the improved power quality and the gradual power reduction process. www.energyinnovation.net

  16. HVACR cycle control managerFor packaged and split systems, heat pump, boilers, chillers with reciprocating compressors, refrigeration, hot water heaters. Results have been so impressive that we automatically include IntelliCon in all energy management projects we initiate in the tri-state area. – Johnson Controls, New York Metro Area IntelliCon installed on 7.5-ton York unit www.energyinnovation.net

  17. HVACR cycle control managerSavings of 10% to 30% on HVAC and refrigeration "Your Intellidyne economizers gave us a 100% return on our investment in their first 9-months of operation." Con Edison Report of Queens Supermarkets DBA Key Food Stores, New York IntelliCon installed on 4-ton American Standard unit www.energyinnovation.net

  18. HVACR cycle control manager The IntelliCon • IntelliCon provides energy management intelligence to equipment that is typically simply cycled on and off according to fixed set points. The opportunity to reduce costs • HVAC systems are sized to meet “worst-case” load conditions, which occur only a small percentage of the time. • IntelliCon supplements the antiquated on/off action of the thermostat or burner (even “smart” ones) with analysis and control of a computer. www.energyinnovation.net

  19. HVACR cycle control manager • Taking advantage of excess capacity and thermal inertia • The physics of thermal inertia, under reduced demand, cause space that has been cooled or heated to gain or lose temperature slowly. • Each cycle, IntelliCon considers current demand, resistance of a large thermal mass to change and excess HVACR capacity. • IntelliCon determines how long each “off” cycle may be extended, while maintaining temperature requirements. • Due to excess capacity, any fractional temperature change is made up in seconds once compressor cycle begins. • This is a dynamic process each cycle, based on changing real-time conditions, unlike a fixed thermostat setting or a timing device. www.energyinnovation.net

  20. A/C ultraviolet (UVC) emitter technologyInstalls at A/C coil to cut energy cost, improve IAQ, eliminate coil cleaning Florida Hospital's experiences have shown UVC emitters at the coil enhance IAQ and infection control, while saving maintenance and downtime. The substantial energy savings are a great bonus.— Florida Hospital, Orlando, Florida UVC installation downstream of A/C coils www.energyinnovation.net

  24. A/C ultraviolet (UVC) emitter technologyStop 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 UVC light is so intense that it destroys DNA of viruses and other microorganisms www.energyinnovation.net

  25. Steril-Aire A/C ultraviolet emitters All A/C attracts mold to reduce building performance • Operating environment of a/c attracts microorganisms, which are microscopic and results in coil fouling of clean appearing coils. • Coil fouling reduces efficiency, requires coil cleaning, reduces IAQ with bacteria and viruses causes disease, lost productivity and absenteeism. UVC destroys microorganisms to improve performance • Ultraviolet-C emitters at coil attacks the DNA of these microorganisms, cleaning them from the coil and destroying their ability to replicate. • This protects against infectious disease, greatly improves IAQ, returns coils to near original design efficiency and eliminates coil cleaning. www.energyinnovation.net

  26. Ventilation control CO2 sensor technologyElimination of excess outside air ventilation in City of Seattle buildings 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 CO2 sensors placed in zones throughout building for Demand Control Ventilation www.energyinnovation.net

  27. Ventilation control CO2 sensor technologyElimination of excess outside air ventilation can save up to 20% The cost for heating or cooling of excessive levels of outside air for building ventilation can be up to 20% of HVAC cost. Occupancy variations and excess ventilation over design levels exist in most buildings. www.energyinnovation.net

  28. CO2 sensors for demand control ventilation Building air intakes are not measured • Most buildings do not measure or control the delivery of outside air. • The use of excessive amount of outside air results in major energy cost. Most buildings are over-ventilated • Excessive ventilation often is 200% to 400% in excess of actual need. • Buildings with occupancy swings incur significant added energy cost. CO2 sensor system can eliminate excessive outside air use • CO2 sensors determine real-time occupancy throughout the building. • System adjusts outside air to match the need and cut HVAC cost 5- 20%. www.energyinnovation.net

  29.

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

  33. Garage fan CO sensor and VFD system Code requirement for garage exhaust fans and actual needs • Garage exhaust fans typically run continuously during all periods when garage is open to protect against unhealthful build-up of CO. • Generally, it is only during heavy traffic periods when CO might rise to a level that would require the use of the fans. • CO generally reaches levels that would require ventilation only approximately 10% of the time of garage operation. www.energyinnovation.net

  34. Garage fan CO sensor and VFD system CO sensor system can eliminate up to 90% of fan energy use • City codes authorize CO sensors (often combined with VFDs) to operate fans only when necessary to keep CO from reaching unhealthful levels. • VFDs on fans maintain constant base level of ventilation and only increase fans to levels necessary if CO is present. • New electrochemical sensor has 5 year rated sensor life and has a replacement cost of only $70 after 5 years. www.energyinnovation.net

  35. Oil-free refrigerant compressor technologyTurbocor oil-free compressor retrofit reducing HVAC costs to 50% This revolutionary compressor 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 Turbocor oil-free compressor www.energyinnovation.net
