Fog Water Harvesting Through Smart Façade for a Climate Resilient Built Environment
Water emergency is one of the terrible effects of climate change; it is defined as the Blue gold of twenty-first century. In this scenario, fog stands as a potential alternative water resource. Many territories are affected by fog phenomenon; here fog collectors have been developed to extract water from humid mass of air. The aim of this paper is to explore the application of this technology in building sector. The Large Fog Collector is the device commonly used for these projects; it is a textile structure, composed of a mesh, two poles and cables. The exploitation of conventional water resources implies a massive distribution system with significant energy consumption and costs. Otherwise, fog harvesting is a passive system; it relieves the stress upon freshwater resources. Nowadays, fog collectors are low tech devices, and fog harvesting projects are commonly developed in arid areas for agricultural and reforestation purposes. Nevertheless, taking advantage of the vertical development of the device, this textile structure shall be integrated in façade, to promote resilient constructions and make buildings water self-sufficient. The paper explores the design criteria for the development of a novel concept of smart water collecting façade. It can promote also shading effect, reducing the use of cooling system, energy demand, so lowering the ecological footprint. Depending on fog Liquid Water Content, the collected water can be used for the irrigation of green roofs, gardens or in an optimal scenario also for domestic use. The analysis of local weather data is crucial to extend the territories where this system can be applied; but, more important, the improvement of the device’s technology is essential to implement it in new application fields.
