Plants

• How can subsist plants in this structure
• Plants dont 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 doesnt stagnate

6
Plants

• The vegetal selection
• Adaptation to this support
• -gtto know the way the plant grow
• Vegatals must subsist on our latitudes 
• Dont endangering  their equilibrium

7
Plants

• The vegetal selection
• 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
Plants

• What about maintenance
• To clip vegetals more invasive plants 1 or 2
  times a year
• To verify sprinklers and the timer, check the
  tissues 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.

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).

15
A role against pollution

• Photosynthesis
• Capture of surrounding dust

16
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
