2. GREEN WALL BENEFITS

3. PLANTS

4. 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

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

6. 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

7. 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.

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

9. 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

10. 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.

11. GREEN WALL BENEFITS

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

13. 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.

14. 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

15. A role against pollution
Photosynthesis
Capture of surrounding dust

16. Mur végétal installé sur la façade des Halles à Avignon (place Pie)
Pleasure of senses
Visual pleasure
The choice of plants
Evolution of colours seasons after seasons
Nice odors
Flavoured odors
Mur végétal installé sur la façade des Halles à Avignon (place Pie)

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

18. 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
