The Symposium Solar Architecture is organised by the Swiss Solar Energy Association Swissolar, the trade journal for architecture and construction TEC21, the Swiss Society of Engineers and Architects SIA and solarchitecture.ch.

 

Soon it will be time to aim high at the Solar Building Symposium in the innovative Zwhatt area in Regensdorf. Renowned architectural firms will once again present outstanding projects: this year’s focus is on the integration of photovoltaics in high-rise buildings, and we will provide inspiring insights into visionary and pioneering approaches to solar architecture. The three themed sessions throughout the day will highlight different aspects of the projects presented, with a focus on financing, approval and sustainable construction. A highlight will be the afternoon tour of the climate-neutral Zwhatt urban district. The 24-storey high-rise building by Boltshauser Architekten, with its striking red facade and integrated cantilevered photovoltaic modules, is literally outstanding – a powerful example of the connection between architecture and renewable energy.
