Abstract

Nature-based solutions (NBS) emphasize the importance of linking biodiversity conservation with climate-resilient and sustainable development plans. In the built environment, artificial ecosystems, such as vertical gardens (VG), cannot be considered NBS if factors such as biodiversity and sustainability are disregarded. This project demonstrates the workflow of incorporating the suitable plant composition in the process of designing a conceptual VG, in a case study in Athens, Greece, while additionally explores the vegetation influence in buildings’ microclimate. Initially, the process relies on digitizing data pertaining to suitable native plant species along with their growth and maintenance parameters; this further enables the establishment of criteria for selecting plants for VG within the architectural proposal. In the second part, a conceptual design experiment of a VG is conducted, where the selected plant species are evaluated in terms of site-specific characteristics, before reflecting on the prospects of the process, in the third part. As a result, this work demonstrates a design approach that is extended to harness local plant capital for the benefit of urban biodiversity. In doing so, it promotes transdisciplinarity by merging different concepts into a coherent, valuable research set that is replicable and accessible to all.
