The aim of the “School of the Future” project which receives funding within the EU’s 7th Framework Program, is to design, demonstrate, evaluate and communicate shining examples of how to reach the future high performance building level. School buildings, their owners and their primary users, namely pupils (the next generation) are the focus of the project. Both the energy and indoor environment performance of four demonstration buildings in four European countries and climates is being greatly improved due to holistic retrofits to the building envelope, the service systems, the integration of renewables, and building management systems. This paper describes the EU project, including all results, a comparison of the four demonstration buildings, and a detailed description of the German demonstration project.
