FINAL B.ARCH THESIS PRESENTATION IIT ROORKEE:
City Centre ,Rohini ,Delhi ,Thesis project (2013)
A Mixed use development project comprises of diverse activities and functions located at the
sprawling District centre in Rohini with site area of 16 acres.With a AIM to explore the symbiotic
character of COMMERCE and CULTURE and to evolve a contemporary model of conventional
Indian market.
Passive solar design is an important feature in the design of this building.The planning and orientation of spaces and building blocks ensures glare free daylight in all regularly occupied spaces. All the linear blocks are oriented in the East-West direction with shorter facades facing the sun.
Most of the south west facing walls are kept blank in order to protect the building from the harsh south west solar radiations. Where the south west walls have openings, they are protected by means of pergolas or projecting balconies. The east, west and south facades of the building have minimum glazing.
This is an Architectural case study on the Centre for Environment Planning & Technology (CEPT) building. Situated in Ahmedabad, Gujarat. This is done by an architecture student in semester 5.

HOW THE HUMAN ACTIVITIES AFFECT THE CLIMATE
India is home to an extraordinary variety of climatic regions, ranging from tropical in the south to temperate in the Himalayan north, where elevated regions receive sustained winter snowfall. The nation's climate is strongly influenced by the Himalayas and the Thar Desert.Though the Tropic of Cancer—the boundary between the tropics and subtropics—passes through the middle of India, the bulk of the country can be regarded as climatically tropical.
Significance of Geographic Information System (GIS) and remote sensing in management of coastal issues. Remote sensing monitoring can serve the dual purpose of water quality monitoring and nature policing.

40.6 °C (recorded on April 24, 2014)
to 3.0 °C (recorded in January,
1964).
CLIMATE
Climatically, whole year can be divided into 4
seasons
• WINTER SEASON
– December, January, February
- Foggy morning, Clear night, Sunny noon
- January is coldest
- Temperature – 24.6 to 10 degree Celsius
• PRE-MONSOON SEASON
– March to May
- Transition between hot summer and wet monsoon
- Temperature increases from March to May
- Local rain and thunderstorms are common feature.
- Atmosphere is dusty in March.
• MONSOON OR SUMMER SEASON

• RETREATING MONSOON SEASON
- Last week of September and first week of
October.
- Temperature and rains fall down gradually.
- Weather is pleasant.
• Guwahati lies in seismic zone
5.
• Zone 5 covers the areas with
the highest risks zone that
suffers earthquakes of
intensity MSK IX or greater.
• The IS code assigns zone factor
of 0.36 for Zone 5.
• Structural designers use this
factor for earthquake resistant
design of structures in Zone 5.
•
• The zone factor of 0.36 is
indicative of effective (zero
period) level earthquake in this
zone.
• It is referred to as the Very
High Damage Risk Zone.
Cwa (KOPPEN CLASSIFICATION)
• Temperate, Dry Winter, Hot Summer.
• HUMID SUBTROPICAL CLIMATES OR WARM
TEMPERATURE
They have a warm and wet flow from
the tropics that creates warm and
moist conditions in the summer
months.
Summer is often the wettest season.
The flow out of the subtropical
highs and the summer monsoon creates
southern flow from the tropics to
that brings warm and moist air to the
lower east sides of continents .
This flow is often what brings the
frequent but short-lived summer
thunderstorms so typical of
subtropical east-coast climates.

CLIMATIC STUDY OF GUWAHATI
GENERAL OBSERVATIONS
• The revenue villages around
Guwahati are mostly dominated by
houses for which bamboo
reinforced biomass was
traditionally used as cladding
material while thatch or
corrugated iron sheets were used
as roofing materials.
• The majority of houses in these
villages around the city of
Guwahati are of traditional
Assam-housing typology where the
roofing system consists of timber
/ bamboo trusses supporting
thatch or CGI sheets.
• The wall system is made of Ikra
and / or bamboo-reinforced
biomass cladding.
• However, a gradual shift towards
confined masonry hoouses (i.e.,
burnt brick masonry walls 6 x 6”
RC posts, RC bands at lintel
level, roof construction made of
timber or tubular steel trusses
supporting CGI sheet roofing) can
be observed.
• The various traditional
construction practices and
housing types that are prevailing
today in the different regions
have evolved based on technology
transfer one generation to the
next by word of mouth or by some
kind of documentation done by
practicing masons and end users.
• The construction schemes have
characteristics that address the
prevalent local conditions of
weather and other environmental
and natural hazards i.e.,
earthquakes, floods or cyclones.
NON‐ENGINEERED CONSTRUCTION TYPOLOGIES
•The variety of non‐engineered construction typologies is quite limited in the city
of Guwahati as well as surrounding sub‐urban and rural areas.
•In general, these building typologies are constricted to the traditional Assam‐
type house as well as both unreinforced and confined clay brick masonry houses.
•The Assam‐type (Ikra) house is a vernacular construction typology made of timber.
•Traditionally, it was the most common building type throughout Northeast India
which is located in the country’s most severe seismic zone, i.e. Zone V –
corresponding to a MSK‐intensity IX (9.0).
•The majority of these houses were and still are used for residential purposes
while the construction technology has been transferred traditionally from one
generation of local masons to the next.
•During the colonial era, the British made this type of construction popular by
preparing specifications and improving the construction technology.
•The advantage of this both lightweight and eco‐friendly construction was well
understood by the successive governments before and after India’s
independence.
•During this period of time, the practice was largely adopted for construction of
government offices and residences across the Northeast Indian states.
•The Assam Public Works Department (APWD) included specifications of this type of
housing in their building schedule.
• In rural areas, these houses are typically built with lightweight
locally available material like bamboo, wooden planks, thatch etc. and are
generally termed as ‘thatch house’.
• These housing types have traditional systems of bamboo posts in rural areas and
wooden posts in more urban areas.
•Bamboo posts are inserted into the ground to act as compression members and are
tied with horizontal bamboo/wooden girders with the help of coconut fibre ropes or
bamboo ropes to give a proper shape and framing action.
•Bamboo or seasoned wood has natural resistance to decay, which makes these houses
sustainable and low on maintenance. It was noted that the majority of houses s
urvived the recent big earthquakes in 1897 (Assam earthquake) and 1950 (Assam
Tibet earthquake).
•Ikra houses are generally single‐storied structures consisting of brick or stone
masonry walls up to about 1 m above the plinth.
•This masonry supports the walls consisting of bamboo woven together with a wooden
frame, and plastered with cement or mud plaster.
•Even though this building typology is more prevalent in rural areas, a
significant percentage of this type of housing can be also found in the cities of
the region.

• Figure 6 – Typical half-wall in bricks above plinth,
which interface with the timber frame panels to contain
the upper part of the wall made of reed with cement
mortar plaster work. The timber posts are bolted to the
plinth. These kind of lighter and well-integrated wall
systems are now replaced with heavier brick work, which
are sometimes not well-integrated and thereby increasing
the falling hazards of walls during earthquakes.
• Figure 7 – Nowadays traditional Assamese houses coexist
along with RC constructions that have become more
popular.

• Guwahati’s building stock is dominated by 3 groups of building typologies
traditional Assam-type houses,
confined clay brick masonry houses, as well as,
ductile and non-ductile RC frame structures.
• In the semi-urban and rural areas around the city, the traditional Assam-type houses had been and still are being
replaced by confined masonry houses while a wide range of variations (especially with respect to used building materials)
can be observed.
• However, these houses can also be found in large numbers in urban areas.
• The urban and sub-urban housing stock is dominated by reinforced concrete frame buildings (with clay brick masonry infill
walls) upto 8 stories high.
• There are a few commercial buildings with greater storey numbers.
• The observed construction technology and workmanship are considered to be fairly good

• Case 7 and Case 8 are preferable as the S/V ratio is less.
• This helps in reducing the heat gained by the interior of the building.
