save the world/green blog hop: Green wall

The railway station in Mt Albert at the tunnel is disgusting, full of graffitti and smell of urine. People avoid using it. An Auckland city councillor has his green fingers on the pulse when it comes to enhancing the Mt Albert rail station.

Graeme Easte is proposing a station upgrade by applying "green wall technology", a system that enables plants to grow directly on a built structure.

Mr Easte says to build a seven-metre-long by three-metre-high wall opposite the station's seated area would cost about $50,000.

The wall would be irrigated from the top and any excess water could be collected and recirculated or allowed to seep into the ground."

Natural Habitats manager Pete de Jager says the green wall phenomenon in architecture and design has become popular since botanist Patrick Blanc covered Paris' national museum wall with plants in 1988.

"Apart from the aesthetics, engineers like them because they reduce the opportunity for graffiti, provide noise baffling, and also improve air quality. Stormwater run-off can also be used to irrigate the structure."

In fact, a cheap version of planting creepers like ivy on a wall already exist a couple of stations to the West. I am very impressed with the red wall less the graffiti.

Great idea. Green walls are also great for home use. If one chooses their plants carefully, they can help cool a building and offer shade. And ... they are beautiful!

Thanks for sharing this!

Gosh, you really mean the word GREEN literally. A great idea, most people around here try to get rid of the ivy around buildings, but I think it can be so pretty, I wonder if there is a disadvantage to it?

One other thing about a green wall - it's probably resistant to taggers. Even if you COULD spraypaint on it, the new leaves would just cover it soon.
