Jefferson Elementary School District
Jefferson Elementary School District in San Mateo County, California serves over 6,000 students from kindergarten through 8th grade. In the face of significant budget cuts in recent years, District leaders sought a solution to put dollars back into the classroom, while reducing their carbon footprint and modeling environmental stewardship in the community. Just as importantly, administrators and teachers wanted to empower students through the introduction of 21st-century learning tools and STEM educational opportunities.
In 2012, the District partnered with OpTerra Energy Services to fulfill their vision to save critical operating dollars by going green in a fiscally responsible way. The comprehensive project included installing solar PV panels on parking canopies or ground mounts at all school sites, improving indoor and outdoor lighting, installing an electric vehicle charging station, and making improvements to the HVAC infrastructure for better air quality and efficiency. In addition, an LCD display showing real-time energy production from the solar system was installed at the District office.
The $12 million project is paid for in part with funds from the 2012 Measure I bond. $700,000 comes from the California Solar Initiative, which provides performance-based incentives for solar energy produced at the District during the program’s first five years.
A Cutting Edge STEM Education Program
OpTerra’s education team and Jefferson ESD leaders collaboratively designed the Growing Stems for STEM educational program to turn classrooms into living laboratories. This project was developed as a part of a greater bond program effort to ‘go green’ and introduce solar power, energy efficiency, and gardening into District classrooms. The program engages 500 3rd through 8th grade students with hands-on activities and Common Core standards-aligned curriculum each year.
As part of the enriched STEM education offering, students received hands-on learning kits, tailored to grade level, including ‘solar suitcases’ which help students understand how solar photovoltaic energy technology works. Additionally, OpTerra engaged 16 teachers in over 14 hours of STEM-focused professional development opportunities to help them link the solar energy and energy efficiency improvements across the District with STEM learning in the classroom. Another professional development session is currently in the planning phases and it will connect solar energy, energy efficiency and sustainability with gardening, thus completing the Growing Stems for STEM program sequence. Growing Stems for STEM expands Jefferson’s gardening program by helping students understand how energy from the sun not only powers plant photosynthesis and the water cycle but also serves as an abundant source of electricity for schools and classrooms. Students come away with a greater sense of their own environmental impact.
The renewable energy project is outperforming original savings estimates and will achieve $16.8 million in savings over the lifetime of the project with anticipated solar generation of 1,612,550 kWh per year across the District. In addition to saving critical operating dollars, the program inspired students through the innovative STEM-focused education program. Through teacher engagement and professional development, teachers and staff learned to understand and utilize the project’s technological components in their classrooms.
By connecting environmentally responsible, cost-saving energy projects with enriching, standards-based STEM classroom activities, the District continues to increase student engagement, enhance classroom learning and improve quality of life for students and staff. HVAC upgrades have improved classroom air quality, humidity and temperature controls, and better lighting supports student attention and engagement.
All of these successes have cemented Jefferson ESD’s leadership across the region, making the District a model of fiscal and environmental stewardship. The District’s utility cost decreased by 90% and the project reduced carbon emissions by over 2.2 million pounds, equivalent to keeping 770 cars off the road each year.
