Modular Green Wall Systems for Sustainable Cities

It is not an overstatement to say a building’s façade is its most important element, for both architects and for users themselves. Façades become more advanced and sophisticated, and there is much scope for innovation: Urban heating, loss of biodiversity, and scarcity of drinking water are among the big challenges imposed on mankind by climate change. Together with the ZHAW Zurich University of Applied Sciences, Switzerland, Sika started a project for developing a modular green wall system that is intended to solve these challenges all at once.

The project is funded by the Swiss Innovation Agency, Innosuisse. While green roofs are an established option for increasing the quality of urban living, façades offer even more potential and, due to vertical exposure, a much bigger effect on reducing urban heating. At the same time, biodiversity and air quality increase strongly. Building green façades contributes significantly to the energy efficiency of a building which in turn helps to minimise the costs and issues associated with high energy bills.

The building’s envelope has become a key focus of any building’s energy efficiency concept and therefore a key focus for façade designers.The next generation of façades are able to generate energy and it's possible that they may be able to be used for energy storage. Energy harvesting façades will become an option as they allow the building to generate energy and move towards full self-sufficiency.

Modular green facades provide a significant improvement of the quality of urban living.
