The ReCO2ST demonstrator building in Vevey is a 1932 apartment building that has been renovated with the ReCO2St approach, fully respecting its architectural identity while also enriching it inside and out to accommodate the selected renovation solutions.


The ReCO2ST approach, is structured to assist the decision making process, but also flexible to allow the permissible interventions leading in a cost-optimal, nZEB, healthy renovation that respects the local environmental, social and cultural contact of the buildings and their surroundings.
