The project draws parallels from the genetic architecture of foliar trichomes in plants to develop dynamic, pubescent surfaces that can regulate heat and atmospheric moisture on an architectural scale. Arid countries like Saudi Arabia face extreme high temperatures and humidity. The blind adaptations of contemporary design and ignorance of environmental conditions has led to a stagnant urban development. Flat glass façades with maximum sun exposure create an immense dependence on air-conditioning and non-renewable energy. As climate change further impacts the trends of rising temperatures and reduced rainfalls in arid and semi-arid regions, it is imperative to develop strategies that can counter the future environmental threats. Therefore, learning from the natural survival mechanisms of desert plants, such as pubescent textures called trichomes and thick waxy cuticles, can help architects and designers to develop strategies that can address the threats posed by climate change in such regions. Trichomes can be de¬fined as hair like structures on the epidermal layer of leaves that help to regulate the rate of transpiration, reduce the heating effect of sunlight and protect the plants from insects and herbivores. Inspired by this phenomenon, the research aims to explore the function of trichomic architectural skins embedded with responsive thermodynamic mechanisms through moisture regulation and evaporative cooling.
