green-walls-could-save-energy-museum-paris_65557_600x450Green 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.

  1. My name is Cliff Barre and for the last year or so I have been writing about green initiatives and green traveling. Within my articles I reference the U.S. Green Building Council and LEED certified buildings quite frequently, similar to your LEED Platinum section of your blog. As you may know, the goal of the USGBC and its LEED certification initiative is to promote a more sustainable future through cost-efficient and energy-saving green buildings. After reviewing some feedback I’ve been receiving, I’m under the impression that “LEED Certification” needs to be broken down and explained more.
    I was hoping to write an article for you explaining what goes into LEED Certification and breakdown the report cards of buildings would receive upon being certified. I believe this topic would fit well with your blog, particularly in the Green Building section. There are different categories and rating systems used to certify buildings, homes, and the construction phase of projects that if explained a bit more might help people have a better understanding of LEED and all that it means.
    I am open to suggestions and ideas from you for me to best tailor an article for your blog and readers.
    Looking forward to hearing back from you!
    Sincerely,
    Cliff
