The project addresses the transformation of the entire village of Zernez in the Swiss Alps to be able to abandon fossil fuels for building operation. To develop appropriate strategies, ecologically as well as economically, the A/S Research Team developed bottom-up modeling based on surveyed building data of 306 buildings. The team used clustering to identify similarities in order to develop cost- and energy optimal retrofit strategies.
Complementary, top-down, large-scale energy infrastructures were researched and evaluated, exploring the interfaces between the urban and building scale. Proposed solutions will be applied in two exemplary pilot projects in the village.
The project Zernez Energia 2020 has been awarded the 'Zürich Klimapreis 2014 - Sonderpreis Bauen und Wohnen'.
