Description

Mosses can actively remove some pollutants, have a large bio-active surface and high transpiration rate. Constructed moss walls use these natural capacities of mosses to reduce air pollution and local air temperature. Some moss walls are constructed with technological additions, for example, ventilators that strengthen airflow through the installation, thereby the increasing air filtering capacity. There are many open-air test sites to examine the effectiveness of the variety of moss walls available on the market.

Conditions for Implementation
  • Space need for loading and unloading
  • The installation surface needs to be flat
