Site Analysis

Feb 12, 2019

 

Site analysis is assessing the site and drawing inferences to aid further design conception and implementation.

Why there is a need of Site Analysis?

  • The assessment provides the relevant information regarding the environment, natural and artificial features of the site.
  • This ought to be used as starting process for the design process.

Site analysis aids in the following ways :

  • Avoiding inappropriate design responses
  • Legal Applications
  • Discovering interrelationships
  • Greater efficiency when designing factors

COMPONENTS OF SITE ANALYSIS

  • Location
  • Neighbourhood context
  • Climate
  • Site

  • To judge the relative desirability of sensory conditions on site.

Factors of sensory:

  • Visual/Views
  • Noise
  • Odour

How to study Neighbourhood Context?

  • It is hereby explained through a residential site example:

3. CLIMATE:

What is climate?

  • Mean weather conditions over a period of time

Why there is need to look for climate?

  • To harness prevailing climatic conditions for creating comfort conditions
  • Protect space and building from prevailing winds, cold and from down pour- rain and snow
  • Efficient daylight into space and building
  • Shade and exposure to sunlight via openings
  • Durability and optimum usage of materials

Components of Location:

  • a. Macro Climate
  • b. Micro Climate

Macro Climate

What is macro climate?

  • Overall climate of the region.
Factors which affect macro climate:
  • Temperature
  • Relative humidity
  • Wind direction
  • Rainfall

Micro Climate

What is micro climate?

  • Immediate local climatic conditions
Factors which affect micro climate:
  • Topography
  • Waterbodies
  • Vegetation
  • Construction materials

Note: Special features like water bodies, green and open spaces near the site affect the microclimate, So allocation of activities on the site should be done accordingly

How to study climate?

  • Macro climate: Climatic information such as rainfall, snowfall, wind directions, temperatures, sun path, all assessed during the different times of the year.
  • Micro climate: To analyse the micro climate according to the occupancy or usage of the project

For example:

a. A Residence

  • Diurnal temperature of the day should be analysed.

b. A School

  • The analysis should be done for the first quarter of the day.

4. SITE:

Why is there a need to assess the Site?

  • To analyse different aspects of site on and around it.

Components of site:

  • a. Size and by laws
  • b. Natural physical features
  • c. Man made features

Size and by laws

What includes in size and by laws?

  • Dimensional aspects and legal verification of site like Building bylaws, Sustainable bylaws, etc.

Why there is a need to study by laws?

  • To ensure the orderly development of site.
  • Sufficient ventilation and air.
  • No building blocks the lighting and ventilation of neighbours.
  • Health and comfort conditions.
Factors of Size:
  • Dimensions
  • Area
  • Shape
  • Boundaries
Factors of By laws:
  • Built up area
  • Restricted height
  • Setbacks
  • Parking
  • Allowable usage
  • FAR, BAR

How to study by laws?

  • By laws is to be studied from the local government development authority for understanding prevailing bylaw

Natural physical features:

What are Natural Physical Features?

  • It includes different landforms of site and its characteristics

Why is there a need to look at Natural Physical Features?

  • To analyse the placement of different activities of site w.r.t. the existing features.

Components of site:

  • a. Geology
  • b. Topography

  • Earth science comprising study of solid earth.

Why there is a need to look at it?

  • To assess the nature of soil and in turn the stability of land and its effect on the building.

  • Stability

How to study geology?

  • It can be analysed according to type of soil.

How to study topography?

  • To study topography through different slope of the land.

For example:

a. Ridge

  • One must consider the locations and elevations of different activities on and around the site.

b. Valley

  • Catchment areas should be planned accordingly
