What we are doing

The Energy transition of the EU building stock needs to evolve from being an energy waster to being highly energy efficient and an energy producer, as a prerequisite for Europe’s 2050 carbon neutrality goal. Achieving those targets requires shifting from the present slow-paced energy renovation market towards a dynamic plus energy market. To contribute to this endeavour, EXCESS will spearhead four innovative demonstration projects, introducing technical solutions that enable buildings to produce more renewable energy than they consume over the course of a year. By implementing demonstration projects in the Nordic, Continental, Oceanic and Mediterranean climate zones, EXCESS seeks to test, validate and share PEB solutions with high replicability potential across Europe. EXCESS merges technical concepts for Positive Energy Buildings (PEBs) with new opportu-nities for the production of renewable energy and self-consumption, as provided by the EU Clean Energy Package. In addition to driving forward the development of building materials to enable PEBs in diverse climatic conditions, a key focus of EXCESS lies on facilitating the integration of building technologies. Further, the project harnesses co-design processes to reflect user requirements and market players’ needs to optimise the integration of innovation technologies. This user-centric ap-proach is instrumental for the development of positive energy building solution packages that can be replicated broadly. By engaging local, regional as well as national and international stake-holders throughout the project cycle, EXCESS [1] supports better policy-making for positive energy buildings and districts; [2] promotes the deployment of integrated energy efficiency / generation solutions in building construction and renovation; [3] raises awareness on the importance of energy efficiency in the built environment.

What we are achieving

ICLEI leads EXCESS' communications and dissemination work package as well as specific replication activities with the aim of raising awareness of the benefits of PEBs, engaging industry and the public sector and roll out rapid replication of PEBs in Europe. The additional role of ICLEI in the project is to assess the proliferation of Plus Energy Buildings across the EU, by means of stock taking, interviews and statistical analyses.
