Holistic sustainable buildings renovation: a case study from Switzerland

Renovation is a pivotal element in realising sustainability objectives in the construction industry, as established by the EU Commission. By analysing a real-life case study in Switzerland, this study provides insights into strategies and measures crucial not only for attaining an energy-efficient building state but also for achieving broader sustainability goals encompassing social and economic aspects. In addition, a general decision-making framework for residential building renovations is provided. The presented case study may serve as a role model for the successful sustainable renovation of other similar residential buildings and stimulate further research that facilitates effective holistic sustainable renovation.
