DEFINITION OF SUSTAINABILITY
* The word sustainability is
derived from the Latin sustinere
(tenere, to hold; sus, up).
* “maintain” “support” “endure”
* The concept of sustainability
centers on a balance of society,
economy and environment for
current and future health.
4/53
DEFINITION OF SUSTAINABLE DEVELOPMENT
* Development that meets the
needs of the present without
compromising the ability of future
generations to meet their own
needs.
* Dynamic process which enables
people to realise their potential
and improve their quality of life in
ways which simultaneously protect
and enhance the earth's life
support systems.
5/53
HISTORY OF SUSTAINABILITY
* First use on March 1972, in report on the "Limits to Growth",
written by a group of scientists led by Dennis and Donella
Meadows of the MIT. Describing the desirable "state of global
equilibrium", the authors used the word "sustainable"

SUSTAINABLE CONSTRUCTION
 A holistic process aiming to restore and maintain harmony
between the natural and built environments, and create settlements
that affirm human dignity and encourage economic equity.
 Sustainable construction aims at reducing the environmental
impact of a building over its entire lifetime, while optimizing its
economic viability and the comfort and safety of its occupants.
22/53
WHAT MAKES CONSTRUCTION SUSTAINABLE?
 Construction is said to be sustainable when it meets
environmental challenges, responds to social and cultural demands
and delivers economic improvement.
23/53
WHAT MAKES CONSTRUCTION SUSTAINABLE?
1. Reduce resource consumption (reduce)
2. Reuse resources (reuse)
3. Use recyclable resources (recycle)
4. Protect nature (nature)
5. Eliminate toxics (toxics)
6. Apply life-cycle (costing economics)
7. Focus on quality (quality)
24/53
WHAT MAKES CONSTRUCTION SUSTAINABLE?
Sustainable construction projects consider:
 Energy efficiency and reducing the energy used
in daily operation.
 Using sustainable construction supplies such as
recycled materials and renewable resources.
 Environmentally sustainable features like
rooftop gardens, water reduction measures, and
the use of nontoxic building materials.
 Using local materials that are both easier and
cheaper to bring in
 Construction of public uses spaces like walking
trails and shaded park that help the structure to
better fit with the natural environment, and add
benefits to the local community.
25/53
WHAT MAKES CONSTRUCTION SUSTAINABLE?
* Routinely designed and maintained to optimize the entire life span,
* Sustainability considerations and requirements should take in building
legislation and standards,
* Environmental aspects should be considered in the project and should
include short-term as well as long-term aspects,
* Policies and incentives provided by the government to support
sustainable building and construction practices,
* Investors, insurance companies, property developers and buyer of
buildings are aware of sustainability considerations and should take an
active role to encourage sustainable building and construction practice.
