microalgae for energy
"...the world’s first (building) to have a “bio-reactor facade” – panels filled with algae which produce energy and can cool the interior"
The tiny green algae will play a huge role in determining the future potential of this technology, which aims to provide shade and a renewable fuel source for the experimental apartment.
The BIQ house was built as part of this year’s International Building Exhibition (IBA) in Hamburg. With 200m² of integrated photo-bioreactors, this innovative passive-energy house generates microalgae biomass and heat as renewable energy resources. At the same time, the system integrates additional functionalities such as dynamic shading, thermal insulation and noise abatement, highlighting the full potential of this technology.
The microalgae used in the facades are cultivated in flat panel glass bioreactors measuring 2,5m x 0,7m. In total, 129 bioreactors have been installed on the south west and south east faces of the four-storey residential building. The heart of the system is the fully automated energy management centre where solar thermal heat and algae are harvested in a closed loop to be stored and then fermented to generate hot water. arup
