Thanks to the contribution from the local community, the Mayor of London Said Khan, and large contribution from businesses like Swarovski and Miwhip we’ve been able to fund and installed a 130 metre long living wall along the playground of the school.
WHAT IS A LIVING WALL?
The Living wall system is an organic based system.
Fundamentally for a long term sustainable solution we need 4 basic ingredients: substrate, plant selection, water management and maintenance.
So what we have here is an organic substrate. So the living wall is designed and pre-grown with a natural based substrate. We’ve selected plants which are suitable to the location but also will have the properties to capture the particular matter and the dust that it’s generated from the A4 into the playground. So we are creating a cleaner environment.
Having said that we’ve also added pollinators and plants that create a great source of nectar for the local bees, butterflies, and birds. So we are actually going to create a natural habitat to the actual environment for the generations to come.
There are 3 areas to St Mary’s Living Wall.
The educational wall where currently we’ve got 3 species :wild strawberries, sage and thyme. Soon, we’ve got a delivery coming here with another 1500 herbs to go into this wall where we are going to be using the children and the parents to actually relate to the wall.
The ivy wall, the most effective in stopping air pollution (and cheapest and easiest to maintain)
The showcase wall, featuring some beautiful plants and flowers
ANS Global have committed to maintain this wall for the next 5 years, free of charge for the Chiswick Oasis project. They’ll be looking after the wall, come on a regular basis, but they will also want to give the children an understanding of what’s in the wall. In fact they are planning to do two talks each year to the incoming generation, one at the beginning of September, in the autumn term and then one in the spring. Because within the planting we’ve got a lot of discovery plants and there will be plants that come out and flower in spring, some that will come out and flower in summer and in the autumn, so the wall will be changing during the season.
ANS will also be adding things into the wall as they are maintaining it, so it will become very much of the school experience.
KEY BENEFITS OF A GREEN WALL
- Reduces urban heat island effect and smog
- Cleans outside air of pollutants and dust and offsets the carbon footprint of people and fuel emissions
- Cleans interior air space by removing VOCs and other harmful toxins like benzene and formaldehyde
- Acts as a sound proofing barrier
- Soil and plants are a natural filter that can clean the water that flows through the wall
- will provide opportunities for biodiversity, through the variety of plant species, which will also provide opportunities for pollinating invertebrates/insects and birds.
- It will in turn offers additional educational and wellbeing benefits for the children and staff
ANS Global has been chosen to provide the school with a green wall along the whole perimeter of the wall facing the A4.
We’ve all been working closely with ARUP on the choices of plants for the various sections of the living wall.
Unfortunately we were not able to build our green wall all the way up to the mesh of top of the brick wall, as this would have made the whole structure more vulnerable to blasts of wind.
So we are now going to have to strengthen the structure of the brick wall itself with steel poles cemented into the ground so that we can then grow our green plants on top of the mesh, thus enhancing the chances to stop the pollution from the A4.
we need your support to do that. Please visit www.Gofundme.com/chiswickoasis
