||Urban areas are increasingly larger and more numerous. They use nearly 70% of energy and are responsible for 75% of world greenhouse gas emissions. Urban areas are strongly dependent on food and water, and this makes them vulnerable and responsible for high environmental impacts. Within cities, most energy is required for housing, which is a major source of emissions. Besides, food production relies on energy (particularly for transportation) and water (in Southern Europe irrigation uses about 80% of deep groundwater).
Fertilecity I project (CTM2013-47067-C2-1-R) started research activities on a new horticultural production system based on multy-disciplinary tools (such as LCA, LCC, energy efficiency and MIVES). Fertilecity I was also founded on agricultural methodologies to analyse crop response and development viability. Roof Top Greenhouses (RTG) are still in early stages of research and implementation. In Europe, such type of production is still beginning, and current pilot RTGs are always disconnected from the building underneath.
The objective of FertileCity II project is deepening on research of urban agriculture in RTGs integrated with the building, providing information and tools that make integrated RTGs possible. During FertileCity I, a new facility started to operate on the ICTA-ICP building roof (UAB). Between January 2014-2016 different lettuce and tomato crops were grown. Such facility is currently connected to the building in terms of water, energy and CO2, but only one-way, from the building to the greenhouse.
FertileCity II will focus on establishing a two-way greenhouse-building connection. FertileCity II will address subjects such as the recirculation of water for agricultural production, detailed energy modelling of the greenhouse-building system and its comparison with conventional greenhouses, the architectural and construction study at building and neighbourhood scales, the development of new protocols, innovations on the use of agricultural waste, sustainability analysis (environmental, economic, social), and the identification of business models and their transfer to national and international entities.
Such symbiosis greenhouse-building (energy, water, CO2…) requires a multi-disciplinary approach which is covered by researchers from UAB (with expertise on environmental matters, water cycle in urban areas, waste and economics), UPC (expertise on energy, architecture, construction, and sustainability assessment) and IRTA (exper
