The renovation-densification of a building is a priori more attractive in terms of energy and environmental impact than demolition-reconstruction. Réno-cité proposes to extend the study to a neighborhood and see if the hypothesis holds true at this scale, by adding social and economic impacts to the prism of analysis.
The project is based on two case studies, in two Swiss cities facing the challenges of ecological transition of the building stock and densification of already built-up areas. Scenarios favoring either renovation-densification or demolition-reconstruction are established and analyzed from energy, GHG emissions, social and economic angles.
If the hypothesis proves correct and renovation-densification is indeed preferable, the results will enable the pilot cities to adapt their public policies, and if they can be generalized, recommendations will be drawn up for other Swiss cities.
