WALL ARMOR: Photobioreactors on the BIQ building are about 2 feet wide, 9 feet tall and and 3 inches thick.
the flue-gas production process—the nutrient for the photobioreactors—is captured and also used to heat water, and surpluses are stored. According to IBA-Hamburg, although it wasn’t implemented, the original plan used photovoltaics on the roof. Though it could easily be done in the future, in the meantime, electricity will be drawn from the grid. While the initial photobioreactor facade design was implemented at an apartment, IBA-Hamburg believes it is a good fit for several other applications, including industrial and commercial constructions, buildings for public infrastructure, trade, or residential buildings. Rainer Mueller of IBA-Hamburg points out that this is an example of algae production technology leaving the lab and being brought to real life, as a piece of architecture. “So now we have to survey the bioreactors,” Mueller
Fueling the future. Whether harvesting and collecting corn stover or growing miscanthus and energy cane on previously unused land, biomass farmers can add to their total yields and significantly increase profits.
