This project aimed to spread the 50/50 methodology from Germany (concept is established since 1994) to at least 50 schools in Spain, Italy, Finland, Hungary,Portugal,Poland,Greece and Slovenia. The basis of the 50/50 concept is that 50% of the total energy (and finally money) savings achieved from the energy efficiency measures implemented by the students are retained by the school, whereas the other 50% will be a net saving on the energy bills often paid for by a public authority (local or regional government). The result is that everyone wins; schools get additional financial resources and students learn about energy efficiency; managers of school buildings (often local or regional public authoritiies) have less energy costs, and energy efficient schools contribute to local energy and climate change targets.The project created and tested a common methodology in 50 schools. It set out to achieve a minimum annual energy reduction of 2.5% for each school, but acutally reduced energy consumption on average by an impressive 9% in the majorty of participating schools.


  • The project successfully spread the 50/50 methodology from Germany to 50 schools in 8 other Member States and achieved total savings of 412,772 kWh in electricity, 1,897,685 kWh in fuel, 588,66 tCO2eq in emissions and €160,235.99 in financial savings on energy bills.
  • Out of the 50 schools that participated over the two years 25 achieved on average energy savings of 8,73% and CO2 emission reductions of 8,33% in the first year (2010). 37 schools achieved on average energy savings of 9,95% and CO2 emission reductions of 9,27% in the second year (2011). The project also managed to expand the EURONET 50/50 network to a total of 197 schools.
  • A school in Hungary achieved over €13,000 of savings and several schools in the other participating countries between €5,000 and €10,000. This was mostly done through behavioural change measures at no costs or low cost measures identified by the schools' energy teams.
  • The 50/50 methodology successfully facilitated collaboration between schools and their local governments. It made a considerable contribution towards the implementation of local SEAP's in general and energy efficiency in public buildings in particular. Since a lot of municipalities are signatories of the Covenant of Mayors this project has effectively contributed towards reaching their targets. A roll-out was piloted to other public buildings e.g. libraries, sports centres and universities.
  • Common educational materials with the participation of the different actors: pupils, teachers, teacher associations, parent associations, to implement the 50/50 concept. An educational pack (e-pack) has been created and tested by every school with guidelines on 50/50 steps, teaching and energy monitoring information, energy measurement devices and a programme to calculate savings.

Lessons learned

  • Schools need time to get used to 50/50 methodology and integrate it in their activities and objectives. Implementing the project during 2 years has allowed that many schools start to get used to 50/50, many of them with significant energy savings, and would like to continue after the end of Euronet 50/50 project.
  • The 50/50 methodology has to be adapted to the situation of every country and educational system. Each partner has adapted the 50/50 methodology according to their own casuistic and nature
  • The 50/50 methodology allows achieving significant savings. Moreover if savings are reached it is a great incentive to continue saving more. Therefore special attention has to be made to savings calculation during a 50/50 project. Training and support to schools and local authorities is essential to facilitate this task.
