“…The ICTA-UAB building is the research institute of environmental science and technology in the compounds of Universitat Autònoma de Barcelona (UAB) that incorporates 4 integrated rooftop greenhouses (Figure 1). It is a unique building that has been served as a research platform to assess multiple issues of urban agriculture (Arcas-Pilz et al, 2021;Nadal et al, 2017;Sanjuan-Delmás et al, 2018). This study is focused on this building to exemplify the environmental consequences of applying single interventions, which otherwise might be difficult to assess since assessing multiple cases will also introduce more variabilities to the assessment.…”

It is widely accepted that urban agriculture provides multiple benefits to society. Rooftop greenhouses are a form of urban agriculture that take advantage of urban resources (urban land, building materials, sunlight spaces) and waste flows (energy, nutrients) to provide food and ecosystem services to cities. However, the integration of urban greenhouses within buildings is a complex issue that must be addressed in-depth. Compared to the well-known conventional greenhouses, the urban environment display different constrains requiring to be assessed in order to later optimize greenhouse building materials. The aim of our study was to environmentally assess rooftop greenhouses and propose improving scenarios. Life cycle assessment was used to detect environmental hotspots and to evaluate different impact categories of an iRTG case study in the Barcelona area. Results showed that the greenhouse environment and ventilation design directly determine greenhouse structures and environmental impacts. Optimized strategies showed a potential reduction of up to 35% of the amount of structural steel used, while less improvement potential existed for covering materials (5%). Compared to conventional greenhouses, 1.6 times more steel and up to 8 times more energy were required to build the urban greenhouse in this study. The assessment revealed that these differences can be reduced by optimizing greenhouse structures to avoid a shift of material flows and environmental impacts from building urban greenhouses compared to conventional greenhouses. In turn, the assessment presented here provides guidelines on how to design and plan urban greenhouse constructions in future assessments. That will facilitate the incorporation of urban agriculture in cities based on consistent environmental assessments, ultimately contributing to the low-carbon future development of cities.

“…To use nutrients more economically and efficiently, recycling and recirculation of hydroponic solutions have been proposed. − Such systems recirculate the hydroponic nutrient solutions for a long time, and the systems can be managed by monitoring the solution’s electrical conductivity. − However, recycling such solutions can spread plant diseases or exudates that stunt growth . To advance, hydroponics will require new methods for improving nutrient usage, possibly by using slow-release fertilizers, − or by recovering the nutrients in hydroponic waste solutions for reuse.…”
