verdecal

Green facades have numerous advantages: contributing to a cooler temperature in the city, they provide psychological benefits, thermal and sound insulation. However, due to costs of upkeep and potential damage to property, they are rarely implemented. Verdecal is a modular system of ceramic facade elements that can accommodate many different plants. The hollow interior of each element supports hydroponic cultivation using rainwater, while four different surface textures offer varied levels of adhesion for climbing plants. By placing glazed variations in specific zones, owners and residents can precisely guide foliage along the wall and keep it clear of e.g. windows. The system is compatible with existing ventilated curtain wall structures, creating a breathable, protective layer without risking water damage or mildew. By 3D printing the elements, details such as hanging points or watering systems are “programmed” into the material itself. In this way Verdecal reimagines facade systems as active components in urban ecology—providing a modern, architectural response to the changing city climate.
