County reduces expenditures through energy efficiency improvements

Eagle County saved a total of $144,094 in utility expenditures during 2010 by reducing energy consumption and improving efficiencies in its facilities. The savings were achieved through a partnership with the Ennovate Corporation, an Aurora-based energy efficiency firm, who made recommendations that were implemented by the county.

Ennovate completed a Technical Energy Audit in April of 2008 on five county buildings, including the Eagle County Building, airport terminal, animal shelter, Eagle River Center and Gypsum Maintenance Center. Through the audit, Ennovate recommended a series of energy and efficiency changes to reduce energy consumption, including electricity, gas and water.

Ennovate guaranteed at least $107,488 in annual savings for the county in its first three years after implementing suggestions from their energy performance contracting (EPC) services.  Calculated savings totaled 34 percent more than the guaranteed amount. The final cost of the project implementation was $761,094, which was funded through the county’s CIP Fund. This equates to a return on investment (ROI) for the project of 5.3 years.

“While much of our attention is focused on renewable energy, it is energy efficiency work like this that should be on the forefront of energy plans,” said Adam Palmer, Environmental Policy Planner for Eagle County.  “As a comparison, to achieve the dollar savings achieved last year alone from the energy improvements and behavioral changes made, you’d have to install a 900-kilowatt solar farm.”

Major improvements to county facilities included replacing the boilers in the Eagle County Building; replacing light bulbs countywide with more efficient T8 fluorescent bulbs and compact fluorescent bulbs; adding occupancy sensors and timers for lighting; installing a pellet boiler at the landfill and utilizing beetle kill pine wood from Kremmling for its fuel; improvements in cooling and heating scheduling with improved monitoring and control software and hardware; retro-commissioning (tune-ups) of facilities systems and adding variable speed motor drives to large fans and pumps.

Many of the changes were implemented by county staff, including a portion of the labor for the addition of the landfill pellet boiler and lighting and electrical for all improvements at the Eagle County Building and airport. Ennovate will continue to monitor usage for two more years as part of the original contract to document the calculated savings and honor their guarantee. County staff will continue to make cost-saving energy improvements as part of its ongoing facilities operating plan.
