HOK recently won the Architecture at Zero Jury Special Recognition Award

I recently came across this website which talks about Bay Common SF Bay marine animals in specific I was interested in the Phylum Porifera which can act like a mini “hotel” or “apartment complex” for other animals.  Wikipedia was where I got the inspiration of  how Water flow and body structures work in sponges

Syconoid – Water flow


Porifera<http://en.wikipedia.org/wiki/Porifera> body structures[10]<http://en.wikipedia.org/wiki/Sponge#cite_note-9>

Most sponges work rather like chimneys<http://en.wikipedia.org/wiki/Chimney>: they take in water at the bottom and eject it from the osculum<http://en.wikipedia.org/wiki/Osculum> (“little mouth”) at the top. Since ambient currents are faster at the top, the suction effect that they produce does some of the work for free. Sponges can control the water flow by various combinations of wholly or partially closing the osculum and ostia (the intake pores) and varying the beat of the flagella. Also Sponges with photosynthesizing<http://en.wikipedia.org/wiki/Photosynthesis> endosymbionts<http://en.wikipedia.org/wiki/Endosymbiont> produce up to three times more oxygen<http://en.wikipedia.org/wiki/Oxygen> than they consume, as well as more organic matter than they consume. Such contributions to their habitats’ resources This is what I have to say

Using the free energy system principles inherent in the form of the net positive sponge type “syconoid” a similar digital massing was built in Vasari and tested with onsite wind analysis.  The results were exciting.  Each unit has open pores that allow air to circulate through the shell into an interior atrium and each unit can control the flow of air. The air is then exhausted with the help of the negative pressure at the opening of the building at the leeward top of the mass which creates a suction effect that periodically pulls air through the system.  This effect would also be heightened with stack effect but was not tested in the conceptual model.  When the air flow is watched in real time animation the effect is similar to a primordial heartbeat causing the flow of air to surge in pulses through the body of the building.  The biomimetic process was very stimulating and  informing the team in our understanding of the origins of complex systems in life and inversely how complex building systems can begin to perform with the efficiency and beneficial attributes of life. Paired with the BIOS-FIN system = The BIOS-FIN (Functionally Integrated NutraFilters)

Using flat panel photobioreactors would grow algae and be incorporated into a building facade system which also functions as vertical light blades. The system could be even more robust if it not only absorbed CO2 from the building occupants but it could also biofiltrate<http://en.wikipedia.org/wiki/Biofilter> greywater waste. Taking inspiration from local salt flats in the bay that system would change color due to different strains of algae and bacteria colonies at different purification.[cid:image004.jpg@01CCADE5.E8270890]<https://biosarch.files.wordpress.com/2011/07/399px-salt_ponds_sf_bay_drod.jpg>  Similar to the tiered cleaning pools of a living bio-filtration ponds structured as artificial wetlands.  The end result is a Light Filtering, CO2 absorbing, Greywater Purifying, Bioenergy producing Rainbow Beauty.
