Project Description

Lake Park High School District 108 of Roselle, IL, was looking for ways to dramatically increase the energy efficiency at the East and West campuses and hired Performance Services to implement a guaranteed energy savings project. Implemented in two phases, energy upgrades at the high schools included new energy-efficient vertical classroom units, controls system upgrades, lighting upgrades, and a cooling tower replacement. The Phase I project was completed in August 2016.


To further reduce energy costs, the District also completed a Phase II guaranteed energy savings project to finance two roof-mount solar PV systems at Lake Park West High School and Lake Park East High School. The combined 1.86 MW solar photovoltaic (PV) system will reduce electricity use by more than 2.2 million kWh. The school solar project is also distinguished as one of Illinois’s largest solar installations with net metering.

Solar renewable energy credits (SRECs) will become an income source for the District. They sell excess solar credits to utility companies that need them to meet certain energy use requirements. Expected revenue from excess solar renewable energy credits is projected to exceed $5 million over 25 years. Phase II was completed in March 2017.

Press Release

After two successful phases, the District partnered with Performance Services in 2020 to begin an additional four phases of work. These phases focused on improving the learning environment for students while generating energy savings. Project improvements included new air handling units, domestic hot water heaters, emergency generators, high-efficiency chiller, high-efficiency boiler, LED lighting, science lab renovations, vertical classroom unit ventilators, and controls upgrades.
