The currently growing global urge of adapting to climatic changes led the team of the applied research platform NEXT Institute to provide an urban solution to this problematic. Designed specifically for the City of Brno, it responds to the need of the City in 2050 to expand its blue-energy infrastructure, improving microclimate and rainwater waste. The City Cell is now at its prototyping stage, and it’s being used as a testing ground before it’s implementation into more permanent projects. The prototype, designed by architecture studio KOGAA, is able to collect various data, concerning urban greenery plantation and rainwater management. Featuring seatings, a night illumination system, daylight shading, and a raised wooden flooring, the structure is thought as an urban furniture made to merge its functions with the public spaces. It’s shape develops from the need of providing shading, water collecting, and the intent to create a spatial communication between the new object and the existing square, also achieved through the two-sided openness. Additionally, its structure was designed with easy replacement in mind in case of damage. The central part of the prototype is a biofilter, which collects rainwater from the roof, filtering rainwater through settling and phyto processes. Once filtered, the rainwater is then gathered in storage tanks, from where it is pumped by a drip irrigation system up to the vertical greenery of the structure’s outer walls.

In addition to the vertical greenery, the biofilter allows water retention and evaporation, allowing the cooling down of the surrounding microclimate. It’s construction primarily consists of pre-dried KVH timber, on which an additional protective coating is not required. Also, all electricity for the LED lighting system as well as for the water pump is provided by two solar panels on the roof, making the whole prototype entirely self-sufficient.
