Waterloo Local School District

The Opportunity

Waterloo Local School District (WLSD), located in a small township called Atwater in Northeast Ohio, entered into a comprehensive energy partnership with OpTerra Energy Services in 2009. After evaluating which improvements could be made to save the most money and energy, OpTerra soon began the design and implementation process. Throughout the development of the energy conservation plan, the District’s primary focus was to enhance the educational environment. OpTerra identified the need for new boilers and roofs, as well as efficient lighting retrofits inside and out, including new stadium lighting, which would be enjoyed by the whole community.

The Partnership

WLSD partnered with OpTerra to modernize two buildings with energy efficient equipment in a 15-year contract. In addition to helping the District secure funding for the upgrades, OpTerra worked closely with District leaders through all phases of the project: analysis, design and implementation and monitoring. A small but powerful change was giving teachers individualized controls for heating classrooms so they could optimize both the learning environment and energy savings.

The Impact

This comprehensive energy efficiency project achieved considerable energy cost savings of over $365,000 for this small district. The District saved over 2,400,000 kWh in energy, avoiding 1,655 metric tons of CO2 emissions, or the equivalent to the carbon sequestered annually by 1,356 acres of forest. In addition to demonstrating WLSD as a strong environmental leader, this project showed its commitment to providing the best possible learning environments to help students succeed.

The project not only empowered teachers to manage the energy use of their classrooms, but it also effectively promoted energy savings through behavioral changes and awareness in the school community. And the stadium’s large-scale lighting retrofit united the larger community together around local sporting events.
