2. Energy and Tree
 Trees play tremendous role in
conditioning environment.
 Cut off 69% sun’s heat from
the ground.
 Reduce wind velocity by 63%.
 Reduce dust pollution by 66%.
 Reduce noise pollution by 50%.
 Planted area cooler in summer
& warmer in winter.

3. Energy and Tree
 Extensive landscaping with trees saves
world from global warming.
 Single tree with large structure and thick
foliage:
- Produces 4.8 tons of oxygen per day.
- Consumes 6 tons of CO2 per day.
 Tolerable limits CO2 = 350 ppm.
 Present level = 390 ppm.

4. Energy and Tree
Lawns, Shrubberies, Hedges, Flower
beds,Ground Material, Water features
 Contribute in creating energy efficient
environment.
 Beautify buildings.
 Add pleasure.
 Make areas attractive & comfortable.
 But expensive compared to trees.
 Productive value is much less.

5. Efficient use of tree
Essential Qualities of Trees to be Used for
Landscaping.
Trees should be:
 Structurally big with abundant foliage.
 Very hardy – facing extremes of weather.
 Highly durable – having very long life.
 Able to stand environmental pollution.
 Suitable for agro-climatic conditions.
 Indigenous species
 Should meet aesthetic requirements.

7. Urban Landscape Design
 Plantation of city roads and streets should be done according to
fundamental design principles.
 Density, Diversity, Form, Colour, Scale to be considered while doing
plantation

8. Urban Landscape Design
 Dense plantation produces excellent composition.

 Trees with big structures & spreading crown creates green tunnel

9. Urban Landscape Design
With close planting
trees develop:
 Tall straight trunk.
 Narrow high crown.
 Does not obstruct views
of the city.

10. Urban Landscape Design
 Tall & large sized
plants are suitable
for narrow streets.
 Look fantastic &
according to scale.
