Sustainable Engineering

2. What is Sustainability ?
Sustainability is…
“development that meets the needs of
the present without compromising the
ability of future generations to meet their
own needs”

3. Traditional engineering Vs.
sustainable engineering

4. Traditional Engineering…
 required to solve problems they are
presented with to the best of their
knowledge
 within constraints of approval authorities
 within schedule and financial constraints
 Engineers search for methods that
maximize function, and minimize cost to
clients

5. Sustainable Engineering
 Maximize social benefit while minimizing
ecological impact
 SOCIAL EFFECT:
Community activities, employment rates,
immigration...
 ECONOMIC ACTIVITIES:
Business growth, employment rates, inflation…
 ENVIRONMENTAL EFFECTS:
- Environmental contaminations,
endangered wildlife…

6. EX: Designing a new computer
infrastructure:
 Traditional engineering:
Focus on performance
 Sustainable Engineering:
How will widespread use
impact electricity demand
and electronics recycling?

8. Sustainable transport
 Transport that is sustainable in the
senses of social, environmental and
climate impacts and the ability to supply
the source energy indefinitely.

9. Transportation and Environment
 Transport systems have significant
impacts on the environment, accounting
for between 20% and 25% of world
energy consumption and carbon
dioxide emissions.
 Greenhouse gas emissions from
transport are increasing at a faster rate
than any other energy using sector.

10. Green Transport
 Green vehicles are more fuel-efficient, but only in
comparison with standard vehicles, and they still
contribute to traffic congestion and road crashes.
 Well-patronised public transport networks based on
traditional diesel buses use less fuel per passenger
than private vehicles, and are generally safer and use
less road space than private vehicles.
 Green public transport vehicles including electric
trains, trams and electric buses combine the
advantages of green vehicles with those of
sustainable transport choices.
 Other transport choices with very low environmental
impact are cycling and other human-powered
vehicles, and animal powered transport. The most
common green transport choice, with the least
environmental impact is walking.
