The main objective of the ClimAct project is the promoting of the transition towards a low-carbon economy in schools. By means of smart energy management, renewable energy, and a change in behaviour, ClimACT will improve the energy efficiency of buildings and will reduce their environmental expenses and their risks to health and safety. Moreover, in order to make use of the awareness potential of the educational sector it will also carry out formative activities to make schoolchildren conscious of the importance of low-carbon economy.
