Exploring green façades as complex systems and their relationships with soundscape quality through a system thinking approach

Green faades, on which plants grow, are increasingly prominent in research and industry.They provide benefits beyond conventional faades.All faades act as a buffer between the outdoor and indoor environment, regulating heat, moisture, light, pollutants and sound.Green faades carry these forward-reducing the urban heat island effect, boosting biodiversity, providing food, improving the microclimate for sound and air quality, and increasing access to nature, which has major benefits for health.Research to date has primarily examined isolated aspects of green faades, such as their impact on outdoor noise reduction, often focusing on correlations rather than causality.This narrow approach overlooks the broader, interconnected relationships between the numerous variables influenced by green faades, including the interplay between faade-induced biodiversity and both outdoor and indoor soundscapes.This study aims to untangle these interdependencies through a participatory systems thinking approach-a method that has yet to be applied to green faades.It is based on participatory systems thinking workshops
