Landscape Architecture

Landscape Architecture is the art and science of

planning and design of out door open spaces, to meet

the physical, economic and socio-behavioral needs of

the users, respecting and in harmony with the existing

contextual natural and man made environments.

Architects, Planners, Landscape & Urban Design

Architects design interior and outdoor spaces (3D)

Planners plan and design Neighborhood /city (2D)

Landscape architects design Enclosures (4D)

Urban Designers creates Place (3D)

Landscape Gardening

Sustainability and Landscape For centuries, theorists of architecture and landscape have vindicated, refuted, modified,and reorganized

Vitruvius’ architectural theory of the interrelationship between firmitas, utilitas, and venustas, that is -

structural stability, appropriate spatial accommodation, and attractive appearance.

The concept of sustainability, however, was never part of the debate, since prior to the industrial

revolution, a much smaller world population and consequentially limited land and resource consumption

meant that the earth’s resources and its ability to absorb pollution were never in question.

Any discussion on the role of sustainability and landscape architecture, or architecture for that matter,

should therefore take as a starting point the now commonly known and often cited definition in the

Bruntland Commission Report of 1983 that

“Sustainable development is development that meets the needs of the present without

compromising the ability of future generations to meet their own needs.”

Sustainability and Landscape

• Winter and monsoon at the Sagar School, Tijara, Rajasthan results in a changing landscape along a 700 feet long eroded and barren

watercourse which was regraded to retain all water on site, and planted with native and adpative species of plants and trees.

• After a year of initial maintenance, the nallah has evolved into a mostly self-maintaining entity and is home to dozens of bird species.

Sustainability and Landscape

A historic artificial lake at Bijoloi outside Jodhpur, Rajasthan next to a Mahraja’s old hunting lodge, retains water off a dry stony watershed, and supports dense native vegetation along the watercourse below it, creating a picturesque landscape embodying sustainability.

Resource Efficient Landscape :TERI GRIHA• Buildings in urban areas consume enormous amount of resources

such as energy and water.

• Resource intensive materials are used to construct the building

envelope and energy consuming systems provide comfort to the

inhabitants.

• The designed landscape around the built environment adds beauty to

the outdoors, while consuming water and pesticides for its

maintenance.

• When a building gets constructed on a virgin site, the natural

ecosystem of the site may easily get damaged.

1. Recycled cement gunny bags were sewn together to provide dust screen around the construction site, Jabalpur

2. Top soil collected and stored outside construction site, Doon School, Dehradun

LEED India1. LEED India rating is as stringent as LEED USA.

2. The only difference is more weightage for water efficiency (2 additional points) and it refer to local codes

like National Building Codes and ECBC-Energy Conservation Building Codes of BEE.

3. It also encourage investment of Green Power sources in the country.

4. It is also planning to recognize safety in the building (Construction Safety) as one of the parameter that

would be recognized in the LEED India rating system.

Modifying micro-climate through energy efficient landscaping1. Plant covered surfaces reflect more solar radiation during the day than those without them.

2. Plants transpire to keep the temperature below damaging levels.

3. The heat stored in plants and soil below them is reduced.

4. Microclimate is the climate of a small area. Factors that alter the incoming solar radiation have the most

obvious effect on microclimate, especially temperature.

5. These can be atmospheric factors, such as clouds, or landscape factors, such as location or aspect relative

to the sun, orientation, soft or hardscape features.

6. Wind also affects the microclimate. Windbreaks, either living or nonliving increase the moisture-use

efficiency of the area downwind.

7. Terrain contributes to microclimatic differences by creating frost pockets or cold spots formed by cold air

drainage.

8. Cold, dense air flows by gravity and collects in the lowest parts of an area.

9. This causes temperatures to differ in relatively small areas. Soil color, moisture, and compaction can have a

significant effect on microclimate.

10. A dark, moist, compact soil stores more heat during the day than a light, loose and dry soil.
