The BIQ house will use microalgae to generate renewable energy for the building while also providing shade.

The BIQ house in Germany, which was designed for the International Building Exhibition in Hamburg, features a ‘bio-adaptive façade’ that uses microalgae to generate renewable energy and provide shade. The zero-energy house is currently under construction and will be the first real-life test for the new façade system.

Algae in the bio-reactor façades grow faster in bright sunlight to provide more shade. The bio-reactors power the building by capturing solar thermal heat and producing biomass that can be harvested. The BIQ house was designed by Splitterwerk Architects, in collaboration with Colt International, Arup, and SSC. Arup’s Europe Research Leader, Jan Wurm, said:
