We renovated Villa Gisel in Zumikon, built in 1966, and integrated a new energy concept. We simulated different intervention alternatives through our BIM process. The most efficient solution was found to be insulating the roof combined with implementing geothermal and solar thermal energy. Thus, the windows and doors as well as the exposed concrete façade could be preserved in their original form.
