Green paint and panels filled with green algae provide an environmental aesthetic for an environmentally friendly building.
ArupThis building doesn’t just have green paint, it has green algae. 

When it comes to powering a home with energy from the sun, solar panels seem passé compared with the technology embedded in the façade of a new apartment building in Hamburg, Germany.

Green slime, not dissimilar to that which taints the Great Lakes and other nutrient-rich water bodies in the warmer months, grows in panels mounted along exterior walls of the Bio Intelligent Quotient (BIQ) House. The algae will be harvested to produce biofuel and help heat the 50 apartments inside.
