Use your Energy Team to monitor the performance of each class or department at saving energy. Come up with an appropriate system to record performance in each class or department. Consider carrying out daily monitoring of: Checks of classroom temperatures (are they within an agreed range)
Some schools have used a token system where good performance is rewarded by a green token in a pot in the classroom and poor performance is recorded by a red token in a different pot. This creates a visual view of the performance of a class. The class with the most green tokens at the end of an agreed period of time gets an award.
Performance could also be recorded with sticker charts so the individual performance each day can be tracked, or electronically via charts which are shared in assemblies. Decide on the recording system that works best for your school.
Rewards for the best performing classes could range from an Energy Saver of the Month trophy, to environmentally themed low cost prizes such as packets of seeds for use in a school garden, going on a class nature/wildlife walk etc . Some secondary schools have rewarded the best performing department with an extra budget allocation.
