Hello BESTers,

After many attempts to embed Photovoltaic systems into building envelopes,
time has come for bioreactors to be tested as facade elements.

The entire frontage of a four-story, corner building in Hamburg, Germany,
has been turned into a living power plant and is now called the Bio
Intelligence Quotient (BIQ) house. Thanks to a $6.5 million
investment, since April 2013, 129 glass bioreactors have been producing
energy and bubbly visual effects.  The concept was devised by a local
inventor and then further developed by a team of specialists at Arup, a
British engineering firm, including Jan Wurm, an architect specialized in
glass structures.

The BIQ's complex circulatory system utilizes compressed air to keep the
algae alive and circulate heat through pipes embedded in room floors;
preheats water stored in 260 ft deep boreholes; and ultimately turn the
wheels of a power generator. Once a week or so the algae are filtered and
trucked to be processed into methane and hydrogen.

Personal comment: given the energy intensive materials, only a complete
life-cycle analysis would confirm any claims of carbon neutrality, but the
BIQ house is certainly an impressive initial exploration of a promising
frontier.
