The Three Little Pigs Never Thought of This Building Material


Bricks, sticks, and hay are decidedly pedestrian building materials in comparison to a new building that just opened to the public last Thursday in Hamburg, Germany. Ambitious architects have built an apartment covered in a thin layer of living, breathing algae.

The building, known as BIQ (for Bio Intelligent Quotient), meets the extremely stringent passive-house standards of energy efficiency set by the International Passive House Association in part by covering the facade with 200 square meters of algae-filled bioreactors. The bioreactors act as a giant algae farm; they insulate against temperature extremes while generating populations of algae that will ultimately be fermented and turned into electricity for the building. Green architecture just got greener.
