Sustainability
represents a
transition from a
period of
deterioration of
the natural
environment to a
more humane
and natural
environment.
Sustainable
development
”Meets the needs of the
present without compromising
the ability of future
generations to meet their own
needs”
Brundtland Report, 1987, United Nati
4. Sustainable development has been defined in many ways, but the most frequently
quoted definition is from Our Common Future, also known as the Brundtland
Report:[1]
"Sustainable development is development that meets the needs of the
present without compromising the ability of future generations to meet their
own needs.
The natural environment works like a living organism, so also the built environment.
The people react with it and it reacts with people.
The Urban environments are the mirror with which we reflect our beings; to look at
our cities is to see into our future (Ozoenemene 2004). Simonds (1961) admits that
when we recreate environment, the environment recreates us.
What is Sustainable development????
5. Ecosystem services

client representative, project manager, planning consultant,
architectural consultant, civil, mechanical, electrical, plumbing and
structural engineers as well as landscape architect, interior designer,
sustainability consultant and other consultants as required by the
project need to work together to ensure environmental sustainability.
SUSTAINABLE ARCHITECTURE
HOW DO WE ACHIEVE IT?
8. -Site selection and analysis-
-Site characteristics such as vegetation, topography, geology, climate, natural
access, solar orientation patterns, water and drainage, and existing utility and
transportation should be analyzed and assessed
-A thorough topographic site plan depicting topography, natural and built features of
existing conditions should be prepared. This will enhance the design and add
aesthetic, economic and practical value.
-Integration of the building and structures with the site so as to maximize and
preserves positive site characteristics
and enhances human comfort, safety and health.
-Indoor Air Quality –
-Indoor air pollution can be controlled by selecting products and finishes that are
low or non-toxic and low VOCs (Volatile Organic Compounds) emitting. Common
sources of indoor chemical contaminants are adhesive, carpeting, upholstery,
manufactured wood products, pesticides and cleaning agents.
- A careful design of a Heating, Ventilation, and Air-Conditioning (HVAC) systems
with adequate supply of outdoor air, good ventilation rates, even air distribution
should be considered.
11. CO2 Production by Country in 2006
• Country CO2 Produced % total world emissions

12. What is an ecological
footprint?
It is a measure of our consumption
and/or emissions as a result of our
lifestyle.
The bottom line is
SMALLER IS BETTER!
Calculating your “ecological
footprint”
… can naturally extend to an
understanding of your “carbon
footprint”

If we are not going to be part of the
PROBLEM.
We are going to learn how to be part of
the SOLUTION!
13. Buildings, as they are designed and used today, contribute
to serious environmental and economical problems because
of excessive consumption of energy and other natural
resources.
The close connection between energy use in buildings and
environmental damage arises because energy-intensive and
monetarily expensive solutions sought to construct a
building and meet its demands for heating, cooling,
ventilation, and lighting cause severe depletion of invaluable
environmental resources.
However, buildings can be designed to meet the occupant’s
need for thermal and visual comfort at reduced levels of energy
and resources consumption.
Energy resource efficiency in new constructions
can be effected by adopting an
Integrated Approach To Building Design.

16. The Multivariate Condition
• Climate varies around the globe and indigenous architecture used to
respond to climate
• 20th century buildings became exclusively dependent on mechanical
systems to heat and cool buildings
• International Style Architecture, characterized by sealed buildings,
tried to create an architectural style that ignored climate
• This has resulted in a proliferation of architecture that does not
properly respond to its climate
• Such buildings now account for between 40% and 70% of energy
use in North America – and this cannot be sustained given Climate
Change (GHG) and fossil fuel shortages
• This lesson will examine how to reconnect issues of local climate
and building design
Buildings and Climate
18. The Comfort Zone
The Comfort Zone refers to the range of temperature conditions of air
movement, humidity and exposure to direct sunlight, under which a
moderately clothed human feels “comfortable”.
This will be different for Indoor versus Outdoor conditions.
These will be different for different CLIMATE types.
This will be different for different cultures combined with climate conditions -
what are people used to??
As Architects we use our buildings to
not only create comfortable indoor
environments, but also pleasing and
useful spaces outside of our
buildings.
There exists a RANGE of comfort
that we need to design within.
19. -Understanding solar geometry is
essential in order to:
- do passive building design (for
heating and cooling)
- orient buildings properly
- understand seasonal changes in
the building and its surroundings
- design shading devices
- use the sun to animate our
architecture.
Why Solar Geometry?
The Perimeter Institute in Waterloo uses
the sun to daylight and add character to the
space.
20. The impact of the sun on our buildings is a direct result of our distance
from the equator.
This affects amounts of solar radiation as well as solar geometry.
Solar Geometry
21. Since little winter heating can be expected from east and west
windows, shading devices on those orientations can be designed
purely on the basis of the summer requirement.
23. Sun path diagram Sun path-a typical example
Vertical and horizontal shadow angle
24. Designing to the Comfort Zone vs. Comfort Point:
This famous
illustration is taken
from “Design with
Climate”, by Victor
Olgyay, published in
1963.
This is the finite point
of expected comfort
for 100% mechanical
heating and cooling.
To achieve CN, we must
work within the broader
area AND DECREASE
the “line” to 18C – point
of calculation of heating
degree days.

25. A bioclimatic chart is a preliminary analysis
tool used during the early planning stages
of a building project.
In the process known as bioclimatic
architecture, an architect uses the
bioclimatic chart to design buildings that
include the most efficient passive cooling
and heating strategies based on the
climate and location of a building site,
according to the Center for Renewable
Energy Sources and Saving.
28. What is Passive Design?
• is based upon climate considerations
• attempts to control comfort (heating and cooling) without consuming
fuels
• uses the orientation of the building to control heat gain and heat loss
• uses the shape of the building (plan, section) to control air flow
• uses materials to control heat
• maximizes use of free solar energy for heating and lighting
• maximizes use of free ventilation for cooling
• uses shade (natural or architectural) to control heat gain
29. The Tiered Approach to Design

30. Solar Chimney
This solar chimney draws
air through
a geothermal heat
exchange to
provide passive home
cooling
Warm air rises and
escapes through
chimney,which creates
an air current for the
cooler air from
underground tunnels to
replace the warm air.
31. Evaporative cooling
Lowers indoor air tempreture by evaporating water.Effective in hot
and dry climates.The sensible heat of air is used to evaporate water,
Thereby cooling the air,which in turn cools the living space
of the building.
32. Embedding the structure partially in earth for conditioning
the inner tempreture.

38. Vegetation can be
used to shade the
building and create
a cool micro climate
around the building.
39. Courtyard spaces can provide a
cool semi private interior
microclimate from which to
draw cool air into the building.
40. Reduce Energy Loads: Day lighting
The tiered approach to reducing energy requirements with
DAYLIGHTING:
Use energy efficient fixtures!
Maximize the amount of energy/electricity required for artificial lighting that
comes from renewable sources.

44. Material Choices
• When designing buildings we
usually have a choice as to
what material to specify
• Materials can be compared as
being more or less harmful to
the environment
• We should obviously choose
less harmful materials
• We should use materials that
use less energy
• We should use materials that
make our buildings more
efficient
• Materials should be both
beautiful and enduring

75. PREVAILING SCENARIO-INDIAN TOWNS
1.India is undergoing transition from rural to urban
society.
2.Increasing migration from rural to urban areas.
3.Mismatch between demand and supply of sites and
services.
4.Disparity between high land costs ,cost of construction
and lower incomes leading to non sustainable
situation.
5.Construction sector provides employment to 16% of
work force.
6. Lack of equitable supply of land, shelter and services
at affordable prices.
7. Environmental paradigms neglected while design and
planning.
8. Depletion of resources in construction and negligence
of ecology in design.
9. Lack of application of cost effectiveness and energy
efficient solutions in construction.
76. What makes a Sustainable City?
• Transportation systems that ensure nodal
connectivity, diverse public transport, and safe
emissions levels
• Clean and Secure Energy through efficiency and
renewable energy sources
• Safe Water and Sanitation provided and delivered
to all community members
• Land Use that maximizes efficiency and ensures
sufficient green space
• Basic Municipal Services such as healthcare and
education.
• Climate Resilience through long-term sustainable
planning
A sustainable city minimizes its impact on local and global environments
while also improving the health and well-being of its inhabitants.
77.
78. Contaminated Air and Water
Dangerous Air Pollution
• Poor air quality in Dhaka alone is estimated to lead to
15,000 premature deaths each year
• Particulate matter concentrations reach 463mcm, over
twenty times the WHO limit of 20mcm.
Poor Water Quality, Quantity, and Delivery
• Surface water quality suffers from urban and industrial
contamination
• Unsustainable groundwater extraction has led to
declining water tables
• Urban piped water supply systems in Bangladesh
serve only 30% of households
Environmental Vulnerability of the Poor
• Low income groups are the most vulnerable because
their health and livelihoods are highly dependent on
ecosystem services
• Slum communities lack sufficient access to income,
food, healthcare, water, sanitation waste disposal,
and basic infrastructure.

plant saplings throughout the
island.
Marina Bay realised
Marina Bay as a seamless
extension of the Central
Business District, was first
mooted in the 1970s. From
just an empty land, it has
become an iconic destination.
DID YOU KNOW?
Land around Marina Bay was
reclaimed throughout the 1970s,
1980s and 1990s.
The first detailed land use plan
was exhibited in 1992. Planners
have worked on this project
from the 1970s until today.
Airport relocated
The international airport was
relocated to the east as
decided in the 1971 Concept
Plan, allowing for several
expansions. It is one of the
busiest in the world.
DID YOU KNOW?
The idea of reclaiming land at Changi
was inspired by then Prime Minister Lee
Kuan Yew’s visit to Boston’s Logan
Airport, where planes took off and
landed over water, reducing
aircraft noise took off and landed over

102. Jurong Island
Jurong Island as a chemicals
hub was conceived in 1991. It
not only supports our
industrial
needs but frees up land for
other needs. It is one of Asia’s
leading petrochemical hubs.
DID YOU KNOW?
Jurong Island has a dedicated “plug
and play” infrastructure to help
companies save on capital costs and
build synergy through product
integration
The island has a rock cavern at a
depth of 130 m, Southeast Asia’s first
Underground liquid hydrocarbon
storage facility.

Bustling hubs
The idea for commercial
and regional centres was
introduced in the 1991
Concept
Plan. Tampines Regional and
Novena Fringe Centres have
since become bustling hubs.
More are underway.
DID YOU KNOW?
The centres were mooted by
planners as a way to better
manage peak-hour congestion
traffic in and out of the city and to
bring jobs closer to homes.

104. Sustaining growth:
Given our limited resources, we will need tocontinue to
sustain our economic growth to provide good jobs,
maintain high living standards, and remain attractive to
visitors and investors With increasing global competition
and the rise of regional economies, maintaining our
economic competitiveness will be even more important to
attract growth opportunities to
create more higher-value jobs.
.
Décentralisation:
To reduce peak-hour congestion from traffic
flowing in and out of the city-centre, regional
and fringe centres outside of the city centre
were introduced in the 1991 Concept Plan to
bring jobs closer to home.
105. Going public :Public transport is a more effective and also environmentally-friendly way to travel as compared
to cars.
The rail network and bus services have been continuously enhanced to make public transport a more
convenient way to travel.
106. Play options:To complete the total quality living environment, creative strategies have been adopted
to leverage on Singapore’s key assets to enhance our leisure environment. One of them is the deliberate
introduction of
greenery everywhere
.
options
The result is Singapore as a City in a Garden, from streetscape and
skyrise greenery to parks within 400 m of most homes
,
113. Climatic mapping:To help create cooler and more comfortable environments for
people to enjoy, URA is leading an ongoing climatic mapping island-wide study
that examines the impact of buildings, greenery, and urban spaces on micro-
climatic conditions like air flow and temperatures.
114. living lab
For cities to address complex urbanisation and
environmental challenges of the future, there is a need
to constantly seek out viable new ideas, technologies,
and smarter solutions.
Singapore sees itself as a living laboratory.
In recent years, many companies and research
institutes, in partnership with government agencies
have developed new technologies and have been
testing out new urban solutions in Singapore that can
be commercialised and replicated elsewhere.
Sustainable water solutions
Intelligent transport systems

115. Jurong Lake District
Jurong Lake District is the largest of three new growth
areas being developed. Covering 360 ha of land, it is
envisioned to provide at least 500,000 sqm of office
space, 250,000 sqm of retail, F&B, and entertainment
space, 2,800 hotel rooms and a number of edutainment
attractions.
Marina Bay
Marina Bay is Singapore’s most ambitious urban
transformation project. It is envisioned as a
vibrant 24/7 environmentally-friendly mixed use
precinct where people live, work, and play in.
Punggol Eco-Town
Punggol Town is Singapore’s first
waterfront ecotown. It is planned
with a holistic framework that takes
into account social, economic, and
environmental considerations.
Punggol is designed to have
smallermore intimate estates with a
central common green.
CleanTech Park
CleanTech Park is set to be the
choice location for green-minded
business owners. Developed by JTC
Corporation, the 50 ha development
will push the
boundaries of sustainability, serving
as a large-scale integrated “living
laboratory” for test-bedding and
demonstration of systems-level
clean technology solutions.
116. Singapore 2030 is no Utopia
but nevertheless, I envision it to be a
place
where ordinary people show civic pride,
are much more conscious of the
environmental
consequences of their personal choices,
where institutions and corporations adopt
sustainable practices not just because it is
economically or politically correct to do so,
but because it is the responsible thing to
do.
To get there, government will need to
further develop a carefully calibrated set of
positive and negative incentives to align
behaviour with consequences
Above all, it needs to show the way in
embedding sustainability throughout its
practices and policies.
117. •Conclusion
•It becomes necessary to adopt the use of alternative building
materials & Construction technologies due to adverse effect of
using scarce resources carelessly and eventual rise in the cost of
the project.
•The Sustainable Design should be seen in relation with the
selection of ecological and economical materials, usage of
recycled wastes and composites which can considerably affect
the economy and ecology of construction
•Product selection can begin after the establishment of project-
specific environmental and economical goals.
118. The process of Sustainable Design is a complex
exercise involving interactive relationships
between Parameters of diverse nature and
varying magnitudes.
A logical process based on quantitative
assessment leading to qualitative decisions that
respond to economical and ecological context
will result in satisfactory environment
comfortable to the human beings,
A SUSTAINABLE HABITAT
