Green Wall applications are growing in popularity around the world. Often thought of as a decorative element they provide much more than aesthetic appeal. Especially in dense urban environments with limited availability of conventional green spaces, Green Walls are seen as a potential strategy to positively affect the local microclimate and help with air pollution. This paper documents an ongoing case study that aims to integrate green wall technology into a conventional rainscreen façade system. The ultimate goal is to standardize the green wall approach on multiple fronts. Through standardization, lower investment as well as maintenance cost and increased reliability a Green Wall rainscreen system will lead to broader use on private/commercial building envelopes and can positively affect the urban climate as a result.
The year 2007 marked the moment when the urban and rural populations on this planet reached parity (Fig.1). After millennia of rural dominance rapid urbanization since the early 20th Century
Industrially produced rainscreen systems have been widely used in façade construction since the early 1960s. But the basic principles of a rainscreen wall go back for centuries. A simple wood
Starting point of this research was the identification of conventional cladding elements that would work in a green wall context. These basic components were then used to develop prototype panels
The present research is focused on two aspects: system design and prototyping. As illustrated above the first round of prototypes were built and are currently being tested under various conditions
