The fifty/fifty campaign incentivised schools to make savings by allowing them to keep 50% of the savings generated by any behaviour change campaigns. This money could then be used for additional energy saving/generating measures such as solar panels.
Each school set up a team of teachers, the caretaker and a member of the staff management team. Their job was to inform the school about the project and their plans to implement it.
Some schools set up teams of pupils to monitor energy and water consumption. Undertaking monitoring encourages the pupils to think about energy waste and on how to save water and energy. Many of the suggestions were integrated into lessons; for example, in the arts class posters were made to advertise the project.
After 12 years 470 schools saved 21.8 Million EURO (=10%), 100,000 tCO2, 355 GWh of heating energy, 49 GWh of electricity and 391,000 m³ of water and the programme has been rolled out to other schools in Germany and other countries.
