SolarLeaf is a bioreactive façade system developed by Arup of Germany to absorb CO2 emissions, producing biomass and thermal energy.
Based on photosynthesis triggered by microalgae contained in bioreactors, the system has been applied on the southeast and southwest walls of BIQ House, a residential building designed by Splitterwerk Architects in Hamburg for the 2013 International Building Exhibition (IBA).
The project was selected by an international panel of judges for the 2014 Zumtobel Group Award, chaired by Winy Maas, for the prize in the applied innovation category.
The judges emphasised that Arup’s project in which energy is produced without occupying any additional space is an outstanding example of how it will be more and more important in the future to develop buildings which not only offer shelter and cut energy consumption but make an active contribution to improving air quality and supplying energy to the urban environment.
