Guaranteed Energy Savings Contract

Total Contract

Oct. 2016

Completion Date

$407,286

Annual Guaranteed Energy & Operational Savings

Project Description

Performance Services was selected by Mokena SD 159 to implement a comprehensive HVAC renovation at Mokena Elementary School and energy upgrades at Mokena Jr. High School. The project not only improved the energy efficiency of the schools, but also the learning environment of the classrooms. 

Mokena Elementary had a complex mix of electric and gas heating which proved a challenge to renovate since it lacked uniformity. Cooling was provided by packaged classroom units which were not only inefficient but did not contribute to an optimal learning environment for students and staff. A new central plant was installed with high-efficiency boilers and chillers to heat and cool the whole building. New Vertical Classroom Unit Vents were installed in the 1st, 2nd, and 3rd grade wings. A new comprehensive vendor-independent control system was installed at Mokena Jr. High School and Elementary which will help maintenance troubleshoot issues.
