”Meets the needs of the

the ability of future
generations to meet their own
Brundtland Report, 1987, United Nati
Sustainable development has been defined in many ways, but the most frequently
quoted definition is from Our Common Future, also known as the Brundtland
"Sustainable development is development that meets the needs of the

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????
• Oxygen and water
• Detoxification and decomposition of wastes
• Conserve soils and their fertility
• Pollination of flowers & Dispersal of seeds
• Protection from the ultraviolet rays
• Maintenance of biodiversity
• Moderation of weather extremes and their impacts
• Provision of aesthetic beauty and intellectual and spiritual stimulation for
the human spirit
Threats to Environment
Severest threat is from us, humans – Pollution•
Air-CO2, SO2, NO, CFC.
Water-Industrial effluents, Sewage, Pesticides, Fertilizers.
Noise pollution, Radiation.
Soil- solid wastes, effluents .
Destruction of Natural Habitats- Deforestation, Hunting,
Reclamation, – Alter the Environment
Green house Gases, Ozone depleting substances.

ARCHITECTURE :The art and
science of making buildings.
Includes technology as well as
- Ecological Architecture:
-Small is good
-Passive Solar Design
-Active Solar Design-High levels Of insulation.
-Efficient use of water and electricity
Thermal mass Ventilation.
-Through Designing Grey water systems
-Low flow taps and showers
- Building materials
-Use of renewable ,nontoxic materials
-Use of recycled, reusable materials
-Use of local resources to reduce transport
-Pre Design Analysis-an integrated approach to design:
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.
HOW DO WE ACHIEVE IT?
-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.
CO2 Production by Country in 2006

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
The Multivariate Condition
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
There exists a RANGE of comfort
that we need to design within.
-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
Why Solar Geometry?
The Perimeter Institute in Waterloo uses
the sun to daylight and add character to the
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.
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.

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.

What is Passive Design?
• is based upon climate considerations
• attempts to control comfort (heating and cooling) without consuming
• 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

Planning for Sustainibility
While our challenges today are vastly different from the 1960s, our
priority remains the same: catering for economic growth and a good

Marina Bay as a seamless
extension of the Central

Land around Marina Bay was

was exhibited in 1992. Planners
have worked on this project

The idea for commercial

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.
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.
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.
Going public :Public transport is a more effective and also environmentally-friendly way to travel as compared

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.
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.

Marina Bay is Singapore’s most ambitious urban
transformation project. It is envisioned as a
