Path to Zero Energy Award Winner
Grace Holistic's project was awarded the Path to Zero Energy Award by the panel of Illinois Green Schools Project reviewers.
Students at Grace Holistic Center for Education built solar charging stations for their classrooms, which required them to learn how to read, monitor, and understand energy usage through Multimeters and Kilowatts Meters. The solar charging stations were used to power Chromebooks, which helped reduce costs, save energy, and improve air quality in the classrooms.
The project began with outreach to the community, other students, family members, the project’s mentors at FGM Architects, Inc, resources available through Illinois Green Alliance, The Climate Initiative, ComEd and the World Wide Web.
Students researched different ways of measuring energy usage, and they explored how much energy is consumed and used in the school. Grace Holistic Center for Education used the Illinois Green Alliance mini grant to purchase Multimeters and Kilowatt Meters, and experts in the community taught students and faculty how to use them. These monitors were used to build their Solar Charging Stations for students’ Chromebooks. The meters show the energy being consumed by each charging Chromebook. The school plans to use electric bills to track long-term cost savings.
The students and faculty learned that Chromebooks utilize anywhere from 6.33W to 11.53W of power consumption while idling and approximately 45 W a day. If the Chromebooks are plugged in with approximately 38 students using Chromebooks in the school, 4 hours a day, with a basic cost of $0.12, they figured a baseline of .18 kwh used per Chromebook at $7.88 year, or 65.7kwh at $299.44 per year.
They used this baseline as a very conservative starting point for understanding their energy and cost savings. The Solar Powered project also helps improve the air quality in classrooms by reducing reliance on fossil-fuel burning energy.
