GREEN WALL BENEFITS

PLANTS

How can subsist plants in this structure Plants don’t need soil in any situation Water and many minerals are essential Plants can grow on rocks, tree trunks Examples : in tropical forests,in temperate climate zones

Plants What about watering? A pump and a timer Water + fertilizer Over the top repeatedly each day , during 3 minutes Water doesn’t stagnate

Plants The vegetal selection Adaptation to this support ->to know the way the plant grow Vegatals must subsist on our latitudes  Don’t endangering  their equilibrium

Plants The vegetal selection More down, we install wallflowers On the top part : plants that are arched bush. More down, we install wallflowers The orientation of the wall reduce the vegetal choice: On a south front :willow tree, armoises , buddleias and lavenders. On a north front : all bracken species, bergenias and luzules.

Plants The planting density. That depends on the vegetals About 20 or 30 plants by square meter (1 plant every 20 cm)

What about maintenance Plants What about maintenance To clip vegetals more invasive plants 1 or 2 times a year To verify sprinklers and the timer, check the tissue’s pockets and regularly bring fertilizer. That is wasted to retire died vegetals

Plants Conclusion: None of these green walls will be similar because all depends on the climate and the exposure. They  are master pieces chefs d'oeuvre, eco-art that mixes up botany, beauty and longevity.

GREEN WALL BENEFITS

Green wall Benefits Thermal and phonic insulation A role against pollution Pleasure of senses Other advantages Conclusion

Thermal insulation Presence of an air layer added to the layer of vegetables play a role of a good thermal insulator Use of deciduous leaves on the sun facing façade permits : In summer to absorb sunshine by the photosynthesis process and avoid the building heating In Winter, to let the sunshine heat the wall.

Phonic Insulation The spring which is air for this act like a shock absorber. Classification C.S.T.B*: level A4 (absorption until 18 dba). * Centre Scientifique et Technique du Bâtiment

A role against pollution Photosynthesis Capture of surrounding dust

Other advantages Protect the wall about bad weather Reduce the thermal sector effect Integration to the environment Develop biodiversity in towns

Conclusion In conclusion, green walls have a lot of advantages not only economically but also environmentally friendly and psychologically, its permits to do energy saving, to have a better environmental quality and to improve the comfort of habitants
