Architectural Award Building Integrated Solar Technology – Wednesday, October 20, 2021


The „Architectural Award Building Integrated Solar Technology“ was established by the Solarenergieförderverein Bayern (Bavarian Association for the Promotion of Solar Energy) in the year 2000. It is one of the few international competitions at the interface between architecture and solar energy. The award honors the planning and designing of excellent building-integrated solar systems and showcases exemplary solutions in sophisticated architecture.

Project 07: Ice Rink Bünzmatt Sports Park, Wohlen (CH)

The ice rink at Bünzmatt Sports Park is located in Wohlen in northern Switzerland. To cover the ice rink, phalt architects from Zurich proposed a steel structure with a segmented gable roof, with steppeddown levels at the height of the respective truss girder flanges. In seven bands, monocrystalline PV modules (378 kW) cover the upper roof surfaces, which amount to about two thirds of the total roof area.

With around 379,400 kWh/a of solar power, this enables 67 % of the sports park’s total energy demand to be met. The side areas with the lower roof sections provide effective, uniform illumination with daylight, which additionally reduces electricity consumption and saves operating costs. This provides a coherent concept for the ice rink roofing, with
meticulously designed verges and a concisely articulated roof silhouette.

Phalt Architekten and Planeco were honored for this project with a special mention in the competition “Architectural Award Building Integrated Solar Technology 2020“.
