Green Walls Reduce Urban Pollution, Boost Energy Efficiency

Green walls have been acknowledged as one of the most effective ways to cut down city air pollution, improve building’s energy efficiency, reduce noise and at the same time give a warm green feel to the usually colorless city architecture.

Imagine walking on the streets of a major city like Paris, battling your way through large crowds and busy traffic, and suddenly entering a “street canyon” of roads between buildings covered with colorful vegetation.

A recent study conducted by a team of scientists at the Karlsruhe Institute of Technology in Germany, led by the biogeochemist Thomas Pugh, shows that green walls can absorb large amounts harmful pollutants such as nitrogen dioxide and particulate matter.

The team created a computer model of green walls covered with generic vegetation in Western Europe, based on factors such as wind speed and building placement. They kept track of various chemical reactions to show that more attention should be paid at the use of green walls to reduce urban pollution.

According to Pugh, the study can provide a solution to the ever-increasing problem of city emissions, and can help governmental officials make clear and simple strategies.
