Open Access research that is exploring the innovative potential of sustainable design solutions in architecture and urban planning...

Strathprints makes available scholarly Open Access content by researchers in the Department of Architecture based within the Faculty of Engineering.

Research activity at Architecture explores a wide variety of significant research areas within architecture and the built environment. Among these is the better exploitation of innovative construction technologies and ICT to optimise 'total building performance', as well as reduce waste and environmental impact. Sustainable architectural and urban design is an important component of this. To this end, the Cluster for Research in Design and Sustainability (CRiDS) focuses its research energies towards developing resilient responses to the social, environmental and economic challenges associated with urbanism and cities, in both the developed and developing world.

The provision of drinking water turns out to be one of the great challenges for the future because central water supply systems cannot technically or logistically be implemented. FogHive©'s main aim is stopping desertification by repairing endangered fog oases ecosystems, and harvesting water for drinking and irrigation and fostering potential inhabitation in many arid coasts such as Chile, Peru and others latitudes. FogHive© is resilient to different climatic contexts and can dynamically response to the different and intermittent prevailing wind directions by keeping the screen ratio of 1:1 or 1:2. It is an adaptable and lightweight design with emphasis in optimal frame types, forms, structural and surface sizes, structural and constructional specifications made with aluminium, galvanised steel or timber. FogHive© employs hydrophobic meshes and a deployable space-frame to intersect atmospheric water and then harvest it for drinking and irrigation. FogHive© has been tested throughout climatic simulations in the fog oasis of Alto Patache, Atacama Desert (2010). It also performs like a shading/cooling device and a soil humidifier for greenery or crop. Being a transformable construction, it can easily be transported and installed. Its footprint is hexagonal (6m side) which is resistant against strong winds and ‘aerodynamic’ to the landscape. FogHive© consists of a water-repellent skin facing prevailing winds and a shading device facing the Equator. The water collector, filtering and irrigation network considers local structural materials and techniques. Regarding conventional two-dimensional fog collection, FogHive© upgrades the following aspects: 1. Increasing rate and yield of advection fog by taking into account harvesting rate and climatic parameters; 2. Structural reinforcement of fog collectors through lightweight and deployable space-frames; 3. Reducing installation and maintenance of fog collection; 4. Lowering physical impacts on surrounding.
