Cities 4.0 is a European subsidy project to support Bologna, Eindhoven, Helmond, Leuven, and Turku in their climate mission. The challenge for all cities is to reduce greenhouse gas emissions from existing homes and buildings. With an average renovation rate of 0.2% in Europe, it would take well into 2050 for all homes and buildings to be modernized. The cities involved in the Cities 4.0 project want to investigate how the renovation of the existing housing stock can be accelerated. An industrialized solution is needed that provides standardized renovations and partial solutions. To identify solutions, a challenge has been set. The selected parties will work on a pilot in Leuven and Bologna.
