SolarLeaf, the world’s first bioreactive façade presented at the BIQ House (designed by Splitterwerk Architects of Graz, Austria), has been shortlisted for the Zumtobel Group Award 2014 in the “Applied Innovations” category.
The demonstrator, specially designed for 2013’s International Building Exhibition (IBA) in Hamburg, is a four-story residential building comprising 200m2 of integrated photo-bioreactors which absorb CO2 emissions while cultivating microalgae to generate biomass and heat as renewable energy resources.
The environment for photosynthesis is provided by glass photobioreactors installed on the southwest and southeast elevations. “This passive-energy house also integrates additional functionalities such as dynamic shading, thermal insulation and noise abatement, highlighting the full potential of this technology.” says Arup.
Now that the technical feasibility of the system has been proven by the BIQ House the consortium is working on concepts for integrating the system on a larger scale to demonstrate the commercial benefits.
