Built Environment
interacts with
Natural Environment in several
ways. Throughout their Life Cycle
they Consume resources
in the form of Energy, Water,
Materials, etc. and emit
wastes.

INTERACTION
Green House Gasses (GHG)
A greenhouse gas is any
gaseous compound in the
atmosphere that is capable
of absorbing infrared
radiation, thereby trapping
and holding heat in the
atmosphere. By increasing
the heat in the
atmosphere, greenhouse
gases are responsible for
the greenhouse effect, which
ultimately leads to global
warming.
KEY DEFINITIONS 5
Global Warming
Global Warming is the increase of Earth's
average surface temperature due to effect of
greenhouse gases, such as carbon dioxide
emissions from burning fossil fuels or from
deforestation ,which trap heat that would
otherwise escape from Earth. This is a type
of greenhouse effect.

Average Global
Temperature
According to NASA, the average Global
Temperature on Earth has increased by about 0.8°
Celsius (1.4° Fahrenheit) since 1880. Two-thirds of
the warming has occurred since 1975, at a rate of
roughly 0.15-0.20°C per decade.

WHAT IS
SUSTAINABLE
DEVELOPMENT
― Sustainable development refers to a mode of
human development in which resource use aims
to meet human needs while preserving the
environment so that these needs can be met not
only in the present, but also for future
generations to come‖ ………. APJ
THE GENESIS- RAPID URBANIZATION
THE GENESIS
CHANDLER & FOX in their exhaustive report on Patterns
of growth in urban areas confirm this migration pattern
existing since time immemorial.
THE GENESIS
ANOTHER STUDY SHOWS BY 2050, 70% OF THE GLOBAL
POPULATION STARTS LIVING IN URBAN AREAS.
INDIA TOO IS NOT GOING TO BE LEFT BEHIND. IT SHALL
CONTINUE TO FOLLOW THE SAME PATTERN.
THE GENESIS
WHAT IS
URBANIZATION
THEN ?
Urbanization is a
process where
haphazard growth
occurs in urban
population.
The current phase
of urbanization is
described as post-
urban phase
THE GENESIS
WHAT IS A CITY ?
WHAT IS A CITY
Cities are very diverse and
complex in nature. They
are like intricately woven
fabric, made of threads of :
Social, Cultural, Industrial,
Economical, Institutional,
political, regional,
Commercial etc.
They are also dependent on
mindsets of its citizens.
SMART CITIES-SUSTAINABLE DEVELOPMENT
― Cities are like
organisms sucking in
resources and emitting
wastes. There are
three variables
responsible for the
collapse of the city-
Population, Environment
and Resources ‖

PROBLEMS IN A CITY 1/4
PROBLEMS OF A CITY
SCARCITY OF RESOURCES- Limited resources like
energy, healthcare, housing, and water. Freshwater
consumption is expected to rise 25% by 2030 due
largely to the increase in population.
INADEQUATE AND DETERIORATING
INFRASTRUCTURE- Most of the key
infrastructure components, like bridges, drinking
water, energy, roads, schools, transportation, and
water, not adequate to provide services to rapidly
growing populations.
ENERGY SHORTAGES AND PRICE INSTABILITY-
Large urban populations are a major driver of
this trend, and cities often struggle to adequately
meet demand due to a lack of supply as well as
inefficient transmission and distribution systems to the end customer.
PROBLEMS IN A CITY 2/4
PROBLEMS OF A CITY (CONTD)
ENVIRONMENTAL AND HEALTH CONCERNS-
The rise in global temperature leads to crazy
things — from hotter heat spells and droughts
in some places, to colder cold spells and more
violent storms, more intense flooding, forest
fires, and species loss in other places. Negative
human health impacts are linked to
environmental impacts — such as air pollution
from burning fossil fuels contribute to air
quality problems: ―Respiratory disorders due to
increase in smog level can damage lung tissue,
and is especially harmful for those with asthma
and other chronic lung diseases.
PROBLEMS IN A CITY 3/4
PROBLEMS OF A CITY (CONTD)
DEMAND FOR BETTER ECONOMIC
OPPORTUNITIES AND SOCIAL
BENEFITS- It’s important to
remember that the ultimate driver of
rapid urbanization is
overwhelmingly opportunistic — the
pursuit of improved economic
opportunities and social benefits.
The rapid pace of today’s migration
is unprecedented. And the promise
of the smart city is to help ensure
that the economic and social
benefits of urbanization are actually
realized by curbing its negative
consequences.

THE SOLUTION – SMART CITIES
SMART CITIES-SUSTAINABLE DEVELOPMENT
WHAT IS A SMART CITY
There are several definitions:
Narrow definition—Cities that use information and
communication technologies to deliver services to
their citizens.
Broader definition- Smart cities use information and
communication technologies (ICT) to be more
intelligent and efficient in the use of resources,
resulting in cost and energy savings, improved
service delivery and quality of life, and reduced
environmental footprint—all supporting innovation
and the low-carbon economy.
Boyd Cohen, an urban strategist helping to lead communities,
cities and companies on the journey towards the smart,
innovative and low carbon economy.
DEVELOPMENT CLASSIFICATION 1/ 3
BROWN FIELD DEVELOPMENT
Existing cities made smart - This partial
approach (step by step; with retrofits and
upgrades) is followed by most cities.
DEVELOPMENT CLASSIFICATION 2/3
New cities, built smart from the start: these
cities are designed to attract businesses and
residents with a master plan that uses ICT to
deliver efficient citizen benefit services.
GREEN FIELD DEVELOPMENT
These are cities established with Specific
purposes example, Industrial cities, Science
towns, Educational etc.

SMART CITY
INDICATORS
• Cities are engines of growth for the
economy .
• Nearly 31% of India‘s current
population lives in urban areas and
contributes 63% of India‘s GDP
• With increasing urbanization, urban
areas are expected to house 40% of
India‘s population and contribute
75% of India‘s GDP by 2030.
• This requires comprehensive
development of
Physical, institutional, social and
economic infrastructure.
INDIAN GOVERNMENT
INITIATIVE
India has been extremely
aggressive in executing
its vision of setting up
100 Smart Cities.
98 cities have been
shortlisted in the first
stage of selection
process. With the
commencement of the
second stage, these 20
cities shortlisted.
INDIAN GOVERNMENT INITIATIVE
GOVERNMENT INITIATIVE 100 SMART CITIES
AND MADURAI IS ONE OF 100 SMART
CITIES. HEARTY CONGRATULATIONS !!!
• Retains many remnants of its historic origins.
• The intricate network of rivers, channel, canals,
tanks and groundwater forms the city‘s essential
blue-green infrastructure, providing
water, drainage and sanitation for domestic,
agricultural and industrial use.
Madurai is an
important
educational,
industrial and
tourism hub.
These are risks
such as water
scarcity, climate
change, growing
traffic congestion
and damage to
important natural
habitats.
The city is growing rapidly.
Expected to rise to over 2 million
people by 2030. This will lead to
further pressures on infrastructure
and basic services.
Madurai is also facing a wide range
of risks that will hinder
future growth and quality of life
unless actionis taken soon.
Increase in average temperatures and rainfall
variability will lead to wide ranging effects on many
sectors, including food and water systems, human
health, buildings, transport, energy and ecosystems.
The city is likely to
be particularly
impacted by
climate change.
Madurai lies in a
warm- humid
climatic zone,
which is hot and
dry with
intermittent and
irregular rainfall.
MAJOR RISKS FACING MADURAI
FLOODING:
The areas which are particularly prone to flooding
include parts of the city which lie within the natural
floodplain of the river and drainage channels.
WATER DISTRIBUTION:
Lack of Network of water distribution within the city and
newly expanding areas.
INADEQUATE GROUNDWATER:
Groundwater serving the city is not of good quality due
to inadequate sanitation infrastructure and seepage of
pollutants into the water table.
DEGRADING ECOSYSTEM:
Ecosystem services such as oxygen production, carbon
storage, natural filtering of toxins and pollutants etc are
reducing due to degrading ecosystem.
BLUE GREEN INFRASTRUCTURE APPROACH
This approach demonstrates how to manage the
interconnected set of challenges relating to Water
Resources management, water supply and water quality,
sanitation, solid waste management, Flooding and
conservation of natural ecosystems in the context of the
urban development trajectory and its changing climate.
The city government
and stakeholders
identified ‗blue green
infrastructure‘ as the
priority issue that
required action.

Good Indoor air quality
encompasses factors as
maintenance of
acceptable temperature,
relative humidity, control
of airborne contaminants,
and adequate ventilation.
Thermal comfort begins
with good design, proper
building management,
and seeks to avoid
uneven temperatures,
radiant heat gains or
losses (e.g., from window
areas), draftiness,
stuffiness, excessive
dryness, or high relative
humidity .
