I have already touched on the fact that house plants can help clean the air in your home, Clean your air Naturally! 21 Houseplants that make great air purifiers, but what can they do for outdoor pollution?
It seems that they might have an impact in urban areas where Green Walls are being built and tested. What is a Green Wall?
Green Wall Technology is the development and application of planting systems that rely of man-made structures as an
armature for vertical growth. Basically, vertical landscaping.
World wide, green walls are being installed to help fight the impact of global climate change. Giving new maning to the term Urban Jungle!
How are they being used?
In what can be called Urban Canyons, city streets lined with tall cement and glass buildings, research by the Environmental Science and Technology, has shown that green walls as well as trees and bushes can reduce pollution in urban environments by as much as 30 percent.
The researchers discovered that the installation of Green Walls and other Greens can be as much as ten percent more effective than what was previously thought!
Some other benefits of Green Walls:
1. Reduction of heating of building walls in the hot summer sun, which will reduce the ‘heat island effect’, and reducing wind chill in the winter to save heating costs.
2. They also contribute to local and regional biodiversity as they offer habitat to insects and spiders, which in turn attract insect-eating birds and bats. If there is a roof garden applied to the building, green walls will also act as a transit route for wildlife between habitat at ground level and those established on higher levels.
3. The green walls bring visual benefits to the local community, for example by planting clematis, honeysuckle, wisteria, passion-flower, morning-glory or jasmine. These plants will provide the vertical garden with highly colorful flowers that can serve as nectar sources for insects, as well as providing a pleasant scent.
Climbing plants shade building walls from the sun and can reduce building’s maximum temperatures by as much as 50% by, at the same time Evergreens provide insulation by maintaining a pillow of air between the plant and the wall and reducing the winter wind chill on wall’s surface. Interestingly, a reduction of wind chill by 75% can reduce heating demand by 25%.
How does it help with pollution?
CO2 absorption, green walls have been shown to be highly effective at trapping dust and concentrating certain dust-derived pollutants in their tissues.
Green Walls are not new, but we are just now realizing the true benefits.
Here are some structures that are amazing examples of Green Wall infrastructure:
Beautiful Vertical gardens inhabit the walls of the Musee du Quai Branly in Paris. Created by P Blanc, botanist and a vertical landscape designer best know for this gorgeous living walls on the Musée du Quai Branly in Paris.
Here is a beautiful demonstration how Plant Walls use water. “A network of perforated plastic pipes run throughout the structure. Every four minutes, under the control of an electronic timer, droplets of nutrient solution are released from the perforations.”
the project is by architect Minsuk Cho. It is amazing how they covered this building with real grass and plants.
A new addition to the Bricault family’s home in Venice California. Just another example of Living walls.
Vertical Gardens improve air quality, lower energy consumption, provide a natural shield between weather and inhabitants. Urban or suburban, cold or hot, indoors or out, the Vertical Gardens can add a bit of green.
In some case Green roofs are also added which can include functional rooftop gardens for urban farming as well as beautiful flowers and plants as in the Home above.
These are just some examples of the beautiful and functional work that can be done. Changing the Urban Landscape and saving the planet.
