Requirements for Designing Living Wall Systems – Analysing System Studies on Hungarian Projects

Abstract

The concept of green façade design has recently come into prominence. Considering it as a new trade that requires its own professionals is quite new. The current innovative structural solutions have extended the research field of green walls to an interdisciplinary level. Architecture, horticulture, engineering (lighting technology, fertilizing technology) are now essential spheres, which can be supported by IT technologies. Studies concerning green walls are cost-benefit analyses, their potential for energy savings or their role in decreasing air pollutants. The fact that 22 m2 plant surface saves 1 tonne of CO2 highlights the application of vertical gardens. Hardly any research examines the practical use and requirements of living wall systems. Although serving the same purpose of creating a vertical green surface, each system has different requirements. The aim of this paper is to reference the essential requirements and important practical information that must be considered when designing a living wall.
