Algae Powered Building Retrofit Wins Metropolis Mag’s Next Generation Design Competition

The competition, now in its 8th year, is for emerging architects and designers to push the limits on design, and this time focused on helping the Government Service Administration re-imagine how it can make their massive number of aging buildings environmentally sound  and better places to work in. The winning team, made up primarily of professionals with 10 years or less of experience from HOK and Vanderweil, used the premise of the Living Building Challenge 2.0  to design a building that was not just a better place to work and made all of its energy on site, but also cleaned the air and water around it.
That goal was achieved by the unique proposal of incorporating huge glass tubes on the southern façade of the building which will hold algae breeders . The technology is being heavily researched by many private and public groups with the hope that the right technology and algae species can create useable fuel. The technology uses waste water from the building as nutrients and pumps CO2 laden air from the freeway  to the basic building block for the plant. The algae then pumps out oxygen and creates fatty lipids which can be burned in co-generators for heat and electricity.
The team pushed the design further by slicing open the vast roof and building a series of carefully placed light shafts. The design will provide daylight for 100% of the interior, a far cry from the cave-like working conditions in the building now. The energy savings start to really add up when artificial lighting is minimized but to get to net zero the team proposes to eliminate all desktop computers and use efficient cloud servers for data management.
Of course, a solar array on the roof and a deep energy retrofit is also in the cards including shading, natural cooling and efficient user controlled heating. Many proposals for net zero energy buildings exist now but few retrofits go so far, especially retrofits that improve the environment rather than just degrading it at a slower pace.
