Project Summary: Bensenville Police Department

Project Location: 345 E. Green Street, Bensenville IL 60106


The Project

The Ogni Group worked with The Village of Bensenville to provide strategic recommendations for financing and energy efficiency design improvements for the construction of the new state- of-the-art Police station. The guidance provided by The Ogni Group reduced the capital costs for the Village and also provided significant grant rebate dollars from the Illinois Department of Commerce and Economic Opportunity.

Background

The project, which broke ground in November 2013, involved re-purposing an existing building into a 48,000 square feet sustainable public facility. While the $16 million dollar project was eligible for LEED Silver, The Village was looking for alternative funding options to reduce capital costs. The Ogni Group provided energy modeling and analysis services to the Village and supported an application to Dupage County for Qualified Energy Conservation Bonds (QECB) funding. QECB is a low-cost financing tool issued by the federal government for state, tribal or local government to fund energy conservation projects that reduce the energy consumption of a publicly owned building by 20% or more.

In addition to creating an energy model to support the bid for QECB, Bensenville worked with Ogni to analyze avenues of energy conservation, and to identify opportunities to qualify for LEED Gold Certification.

The Solution – QECB

Ogni created a whole building energy model for the proposed police station using industry standard software EnergyPlus, which compares the designed facility to the ASHRAE 90.1 baseline.
Ogni identified energy reducing measures that provided operational utility savings by upgrading the thermal resistance roof insulation from the industry standard value of R-20.8 to R-42.72. Ogni also proposed the upgrade of the air-cooled chiller in the facility from an energy efficiency ratio (EER) of 12.75 to 14. The improvements to the roof insulation, and the improved chiller efficiency resulted in an energy savings of 30.68% and a cost savings of 30.78%. These improvements qualified The Village for QECB bond funding and awarded $6.8 MM allowing The Village to save up to $1MM in interest cost. http://www.chicagotribune.com/suburbs/elmhurst/community/chi-ugc-article-bensenville-police- facility-awarded-68-mill-2014-09-12-story.html


The Solution – Energy Efficiency Project Funding

The Ogni Group identified rebate grant opportunities for the project through the Department of Commerce and Economic Opportunities (DCEO), a state funded program for energy efficient upgrades in public facilities. Bensenville was approved by DCEO for a total incentive of $117,788 to install measures of higher efficiency than ASHRAE 90.1 2010.

Conclusion

In addition to being a LEED New Construction sustainable site, the facility will be incorporating high efficiency equipment which will reduce operating and maintenance costs through the life of the building. The Village of Bensenville Police Station is now LEED Gold eligible and has been awarded an incentive of $117,788 from DCEO in addition to bond funding of $6.8 MM through QECB.
