Roof water-farm

Upscaling und Übertragbarkeit des modularen ROOF WATER-FARM Ansatzes werden von der "Schraube zur Gesamtstadt" nachvollziehbar. ROOF WATER-FARM kommuniziert künftige Stadt- und Infrastrukturentwicklung zielgruppenübergreifend und alltagstauglich. Ergänzend zur Demonstration der Technologie (Pilotanlage) und zielgruppenübergreifend dient das E-Book als Inspiration und Werkzeug für den nachhaltigen Stadtumbau im Kontext von Wasser, Nahrung und Kreislaufstadt./Fresh fish and fresh vegetables harvested directly from the roof, produced with treated wastewater from the building, that is the vision of ROOF WATER-FARM (RWF 2013-2017). Water-Farm technologies such as aquaponics and hydroponics as resource- and space-sensitive farming systems are at the focus of urban and infrastructural transformation processes towards the loop city. RWF first-time investigates the link of these light-weight farm systems with technologies and modules of building-integrated (waste-)water recycling. Besides the theoretical reflection of rainwater use, the hygienically-safe treatment and use of greywater (kitchen, bathroom) as service water for the production of fish and edible plants is investigated and tested on a practical level. In addition to, the project first time tested the production of an urban liquid fertilizer ("goldwater") out of blackwater (toilet) for an resource saving urban food production. Based on and via an upscaling process building studies and building passports are developed for conventional typologies such as residential buildings, educational buildings, hotels or commercial buildings. Networking maps envision the loop-oriented city transformation exemplary for distinct Berlin neighbourhoods from the inner-city, via the periphery to areas of transformation. The publication summarizes the results of four years of interdisciplinary research in the format of a compact manual. It shows technological and urban design strategies linking decentralized wastewater and food production as multifunctional infrastructure within the urban context. The results of practical and design work are shown at different scales: technology, building, neighbourhood, city as well as from the perspective of RWF actors and users. A Toolbox offers additional materials and examples focussing topics such as operation & maintenance, feasibility or life-cycle assessment. Upscaling and transferibility of the modular ROOF WATER-FARM approach become understandable "from the screw to the city scale".
ROOF WATER-FARM communicates future city and infrastructure development to a broad audience suitable for daily-use. Complementary to the technologie showcase (pilot plant), the e-book functions as cross-sectoral inspiration and tool for the sustainable urban transformation facing urban water, food and the loop city.
