Abstract
In Sweden, green walls are relatively unknown. However, the technology in itself is not new; it has been used for several years in countries such as France, but it is only in recent years that the interest in green walls has increased in Sweden. In 2013, one of Sweden’s first public green walls outdoors was built at Sundstorget in Helsingborg. Furthermore, scientists from the Swedish University of Agricultural Sciences in Alnarp built two green wall systems in Malmö, which they have been studying since 2012.
Having plants in an urban environment has many benefits, including cleaning the air of pollutions, reducing noise, reducing the air temperature in cities, and increasing biodiversity. A green wall can also affect the temperature of an... (More)
In Sweden, green walls are relatively unknown.

Furthermore, scientists from the Swedish University of Agricultural Sciences in Alnarp built two green wall systems in Malmö, which they have been studying since 2012.
Having plants in an urban environment has many benefits, including cleaning the air of pollutions, reducing noise, reducing the air temperature in cities, and increasing biodiversity. A green wall can also affect the temperature of an exterior wall through shading in the summer, thus reducing the need for indoor cooling.
There is not enough research on how green walls affect the underlying structure, particularly regarding moisture. The purpose of this study was therefore to increase the knowledge of green walls in the Swedish climate. The main focus was to examine how the green wall can affect the underlying structure. Two different systems were studied; one commercial system based on modules and one homemade system based on pockets.
The results showed that the green wall sometimes protects the underlying structure from precipitation. This applies only if the system is properly constructed and installed. The relative humidity of the brick wall behind the commercial system does not seem to be adversely affected by the green wall. However, a poorly constructed system could lead to increased relative humidity, which can cause water damage within sensitive structures. (Less)
