The research project aims to develop a brick-based facade system with (possibly self-supporting) wall modules for dynamic facade greening, cooling, and retention. The modules are intended to form a robust building envelope that creates vertical biodiverse habitats for flora and fauna, simultaneously enhancing the climate and aesthetics of urban spaces and mitigating the impacts of extreme weather events. The capillary water-retaining property of clay, with high weather resistance, will be utilized to store water, irrigate vegetation, and provide evaporative cooling. The surface of the modules combines aesthetics and function through a deliberately porous and visually appealing structure, facilitating plant establishment and anchoring, as well as directing moisture outward. Ideally, the modules will be an integral part of the rainwater system and be directly moistened by the water from the roofs. During heavy rainfall, water can be temporarily stored and released in dry periods through a cistern. The goal is to minimize technical complexity. Vertical planting systems traditionally employ taller plants to achieve the appearance of a lush green wall. However, high failure rates due to frost and drought result in high maintenance costs and unsightliness. Our system aims for a dynamic development of self-regulating plant communities by using locally adapted, low-growing plants and encouraging spontaneous vegetation. In conjunction with an aesthetically appealing surface structure, an attractive image is created at all stages of development, providing habitat and retention space without relying on widespread greening, and achieving cooling effects through plant evapotranspiration and module water evaporation.
