ENERGY@SCHOOL: energy optimization and behavioural change of Central European schools is a cooperation project. The Interreg CENTRAL EUROPE Programme improves capacities for regional development in innovation, carbon dioxide reduction, the protection of natural and cultural resources as well as transport and mobility. With a budget of 246m EUR, this EU cohesion policy programme supports public and private organisations to work together across Central Europe. ENERGY@SCHOOL results have been reached thanks to an integrated approach educating schoolsstaff and pupils to become Seniorand Jun-ior Energy Guardians (EGs). During the span of this programme, there were 8 tested pilot solutions of EE & RES applications in schools under direct contribution of EGs in form of guidelines, toolboxes, and best practices, all of which will be capitalized after the project conclusion. The aim is to set up an Energy Management System for public schools in order to monitor and improve energy consumption.
