Integrated approach as a prerequisite for nearly Zero Energy Schools in Mediterranean region-ZEMedS project
This article deals with an integrated nearly zero-energy buildings (nZEB) approach for the retrofit of Mediterranean school buildings, in the framework of ZEMedS project. EU energy policy encourages member states to start converting building stock into nZEB and public authorities to adopt exemplary actions. In Mediterranean regions of Italy, Greece, Spain and France, there are approximately 87.000 schools, consuming in a rough estimation around 2Mtoe/year. The final energy consumption of typical Mediterranean school built in the period 60-80’s was estimated, on an average of 100 kWh/m2 /y in final energy for all uses. A holistic approach should combine measures to achieve energy performance and indoor environmental quality (IEQ), as well as strategies to involve the users, particularly the future generations. ZEMedS project covers a complete renovation path, tackling strategies for the envelope, the systems and renewable energy applications as well as the energy management and users' behaviour. In this context, the first results are presented with case studies of school buildings to be analysed in terms of the energy efficiency and cost optimality so as to define a detailed renovation action plan.
