A new apartment complex in Germany is intentionally growing an algae farm on its facade, in order to power the building. The hope to use the green slime to produce the building’s heat, as well as cool the building. It’s a new definition of "green!"
Will we see more green buildings in the future? In the April 25th edition of the New York Times, David Wallis quotes the building’s publicist, Rainer Muller, as saying, "Using algae as an in-house energy source might sound futuristic now, but probably will be established in 10 years."
The algae are farmed on adjustable louvers which cover the building’s surface and are fed liquid nutrients and CO2.
