Modelling the water demand of vertical greenign systems
Abstract
Green walls are a nature- based solution for implementing urban in densely built-up areas. They combine a wide range of functions and contribute significantly to mitigating the negative effects of climate change. For example, they can be used, ideally simultaneously, to cool the street space and buildings, for rainwater management precipitation retention measures, for cleaning grey water and the air, and as a biotope for insects. Despite their wide range of functions and applications, green walls have been studied much less than other green infrastructures, such as green roofs. For this reason, there is a great need to collect measurement data of green walls and to develop models for the behaviour of these systems. Among the models to be developed, those for the water demand and the evaporative cooling of the plants achieved by this take on a key role. The need for such models is also reinforced by the fact that with the increasing implementation of green infrastructure, discussions about its water requirements and the extraction of the necessary water are increasing. For this, models to quantify and analyse the water demand of green walls are essential. Currently, no such model is available. The aim of the present project is to develop models for the water demand of green walls on the basis of measurement data from an experimental green wall, using a combination of physical models and machine learning. The model will subsequently be used to quantify the water demand of green walls in order to determine suitable resources (e.g. drinking, rain or grey water) depending on the local environmental conditions and to determine the effects on the local water cycle.
