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 Innovation Group Tomorrow’s Energy Technologies Today www.energyinnovation.net
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.energyinnovation.net

Ventilation control CO2 sensor technologyElimination 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 CO2 sensors placed in zones throughout building www.energyinnovation.net
Ventilation control CO2 sensor technologyElimination 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.energyinnovation.net
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.energyinnovation.net
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 CO sensor installed in parking garage www.energyinnovation.net
Garage fan CO sensor and VFD systemGarage 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 Control unit www.energyinnovation.net
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.energyinnovation.net
