INTRODUCTION The Indian Institute of Management Kozhikode was set up by the Government of India in collaboration with the state Government of Kerala as the 5th Indian Institute of Management. It was established in 2001 • The campus is designed by the late architect Joseph Allen Stein and Stein Mani Chowfla Associates, New Delhi.
ABOUT THE
ARCHITECT Joseph Allen Stein (American architect) Life span: 10th April, 1912- 6th October, 2001 Famous works: Indian Habitat Centre, Express Towers Awards: Padma shri Philosophy: Modern Regionalism- The building should reflect the culture and tradition of its region through its design and materials.
LOCATION The campus is located in Kunnamangalam, 15 km away from Kozhikode along the national Highway, NH 212 towards Wayanad. It is about 30 kms from karipur International Airport. • Latitude: 11.25°N • Longitude: 75.77°E • Altitude: ~100m
Site Area: 97 Acres • The institute is located in the scenic ambience of approximately 80 acres in Kunnamangalam, spread on two hillocks with a valley in between, , located amidst the scenic setting of the Western Ghats
CLIMATE • Climate: Tropical humid climate • Annual Rainfall: 250 cm to 300 cm (nearly 70 % of the rainfall is contributed by the south western monsoon) • Wind Direction: South West to North East
• The panoramic view from the hilltop is a visual delight and conducive for learning and contemplation. • The design of the Campus is aimed at preserving the existing ambience and incorporates strong architectural traditions of Kerala. Laterite Soil: • Laterite soils are formed by weathering of Basalt and gneiss under hot humid climate. • Loamy in texture without gravelly vesicular nodules • Laterite soils are red in colour and acidic in reaction.
TOPOGRAPHY • The shape of the site is irregular • The topographical character of the site has been instrumental in determining the location of the academic and residential area. • They each occupy the summits of the two hillocks. • Spread on two hills with the buildings blending in the lush greenery with a mix of traditional Kerala style ethnic architecture with modern amenities
HYDROLOGY • There is no independent water source that can provide water to the whole institute. • Water is collected from all the roofs and collected through a system of channels at the bottom of the hillocks to a pond, which partially meets their water requirements. • The fact that the location receives an abundant amount of rain has been manipulated and rainwater harvesting techniques have been incorporated into design.
It catches rain from at least two thirds of its whole campus. (The topography is such that some portion of the water has to go from the back portion of 2 hillocks, but a major portion of run-off gets down to the front side)
At the foot of the hillock, there is a huge pond of 1.5 acres dug only to catch rain water.
Rainwater harvesting has been implemented at IIMK by utilizing the rainfall run-off from the roofs of the Campus buildings by means of eave-level gutters and downpipes which lead to storm water drains built by the road sides. • This together with the rainfall run-off available from the Campus land forms the catchment area for the rainwater harvesting scheme The run-off collected through a network of storm water drains lead to the re-charging area on the upstream side of the storage facility, i.e. the Rainwater Harvesting Pond. • The re-charging area is basically left water-logged, especially during the rainy season, to allow the stagnant water to percolate down and filter through the natural soil strata and indirectly charge the Pond. • This indirect charging prevents contaminated surface run-off, carrying silt and other impurities, from polluting the Pond. • Flooding in the charging area is prevented by leading away the excess water, along with overflow from the Pond, through another drain which bye-passes the Pond. • The harvested rainwater is treated and then pumped to an overhead water tank for distribution.
• The run-off from the upper parts of the hill is not directly fed into the main pond. It is spread in an adjoining piece of land, about five acres in extent. This is the catchment area; it has an areca nut garden and a thick layer of weed wines covering the ground. • An old pond inside this garden is maintained as it is. This pond accelerates the rate of water percolation. • The building team marked the contour lines of the hills and retained some of the older gullies that acted as storm-water drains • On both sides of the drain, a grass variety such as cynodon was planted. After a year, though the dams have almost washed off, the vegetative growth has established. This cuts the velocity of water to some extent.
Water Management: • Reduction of 59.26% from the GRIHA base case has been demonstrated in the building water demand by installing water efficient fixtures. • Reduction of 76.77% from the GRIHA base case has been demonstrated in the landscape water demand. • Hessian cloth was used for curing of columns and ponding technique was used for curing of slabs. • The project meets 100% of the water demand through reuse of treated water and collected rainwater. • The Campus boasts of rain water storage tanks with 40 lakh liters storage capacity which have been provided under the campus buildings so as to meet any emergency requirement. A Sewage Treatment plant has also been established in the campus for treating effluents which can then be used for toilet/wash room flushing and gardening/irrigation purposes.
Water and Waste: • Reduction of 50.16% from the SVAGRIHA base case has been demonstrated in building water demand by installing water efficient fixtures. • Reduction of 53.44% from the SVAGRIHA base case has been demonstrated in the landscape water demand. • Rainwater recharge pit of 1,14,290 litres capacity has been constructed on site. Waste Management: • Multi-colored bins have been provided at every floor to collect and segregate waste at source. • A dedicated place has been provided on site to store segregated waste prior to disposal.
• Rainwater Harvesting, implemented in IIMK has been an eco-friendly solution to the problem of non-availability of a sustainable source of drinking water. • Along with harvesting of rainwater, we are also implementing water conservation by collecting the sewage (waste water) generated from the Campus and, after treating it by means of a state-of-the-art Sewage Treatment Plant, utilizing the treated effluent for horticultural irrigation purposes. • Control of soil erosion, along the natural (unlined) storm water drains has also been effectively achieved by providing vegetation and other eco-friendly measures. • Therefore, the rainwater harvesting initiative adopted in IIMK aims for a sustainable and eco-friendly water management strategy combining water and soil conservation measures.
AESTHETICAL VALUES Its due to the careful integration of the indoor and outdoor spaces that the otherwise monotonous effect of similar looking buildings has been eliminated . Symmetry can also be beautiful
In spite of large amount of trees and vegetation their is a variety of beautiful and aesthetic plants and trees
VEGETATION Calicut is a green state having variety of trees. Coconut tree state tree of Kerala tall and branchless
Araukeria
Asoka Tree Cluster fig tree large deciduous tree grows in evergreen forests, moist places, near streams
Trees are very useful in various ways where it provides food, medicine, timber, firewood etc. ExPeepal, Ashoka Tree, Neem, West Indian Medlar, Silk Cotton Tree, Golden Shower Tree, Devil Tree, Sandal Wood, White Palm Tree etc.
•
Site is characterized by two hillocks- the academic area and the housing area are situated on each hill top respectively, thus meeting the needs of adequate privacy. • Housing for the faculty is provided on the residential hillock Parking area, at the basement of the library block, ramp, to connect the parking lot Housing - according to terrain of the site . Block Academic Block
• Because of the terrain, there is a play of level differences.
CAMPUS
Entry The entrance to the campus is situated at the base of the hill.
SPACES - THE CENTRAL COURT: • The core feature: All the buildings are oriented to a central court - typical “naalukettu” of Kerala’s traditional architecture giving a sense of unity. This central area holds an open air theatre. • The buildings are connected by walkways which defines this central green oasis. • Remaining surface is articulated by paved portions thereby giving a sense of scale & directing to various buildings around.
THE CIRCLE OF CONTEMPLATION: A circular green area is located in the front facing the entrance of the academic block. It is covered by pergola along the sides with vegetation growing on it.
VANTAGE POINT: It is a viewpoint from where an unobstructed view of the Western Ghats can be perceived
VIEW: The entrance area of the main building is approached by winding roads. The building will be visible only when one reaches the top creating a sense of surprise.
FOCAL POINT: The high watch tower stands as the focal point, it acts as a sculpture and has no relevance to the character of the building and the institution. The watchtower stands out as one turns the corner at the final approach to the summit. Use of locally available materials – exposed stone work, tiles used for pavements.
Interesting play of built & open spaces gives a feel of the building interacting with the nature.
Elements of traditional architecture of Kerala reflected in the building’s sloping roof and Mangalore tiles.
CAMPUS CIRCULATION: • Approach by winding roads • Roads run only on the periphery of the campus • Internal circulation made by pedestrian paths • There are covered walkways connecting each block.

Spaces are considered the primary means by which landscape are organised ,understood, used and experienced.
FOCI: It refers to differentiated , contrasting or isolated forms or places in the landscape that posses cultural ,social , practical functions because of their visual distinction.
PATHS: Like space paths are also considered primary design forms that influence the use and experience of landscape.
The following strategies were adopted to reduce the building impact on the natural environment: Sustainable Site Planning: • Out of 1,119 existing mature trees, 107 trees were cut and 585 new trees were planted. • Air pollution control measures such as site barricading, wheel washing facility and other appropriate measures were strictly adhered to during construction Sustainable Building Materials: • Fly-ash bricks and AAC blocks have been used for walling in the project. • Pozzolana Portland cement with 34.4% fly-ash content by weight has been used in plaster and masonry mortar. • More than 70% of the materials used for internal partitions/ paneling /false ceiling /in-built furniture are low-energy.
Energy Optimization and Occupant Comfort: • Digital timer control has been provided for 100% of the outdoor lighting system. • EPI reduction of 66.11% from the GRIHA benchmark has been demonstrated. • 52.3% of the habitable spaces are day-lit and meet the daylight factors as prescribed by NBC code, 2005. • 50 kWp solar PV panels have been installed on site. • Solar hot water system (flat plate collector type) of a total of 16,000 lpd capacity was installed in the project.
