Energy Efficient Landscape

Presented by:

Ar. Bineet Chhajer

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.

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.

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.

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.

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

Urban Landscape Design

Dense plantation produces excellent composition.

Single kind of plants creates excellent collective impact.

Trees with big structures & spreading crown creates green tunnel

Urban Landscape Design With close planting

trees develop:

Tall straight trunk.

Narrow high crown.

Does not obstruct views

of the city.

Urban Landscape Design Tall & large sized

plants are suitable

for narrow streets.

Look fantastic &

according to scale.
