“Engineers play a crucial role in improving living standards throughout the world. As a result, engineers can have a significant impact on progress towards sustainable development” World Federation of Engineering Organizations

What is Sustainable Development?

 Birth of Sustainability Brundtland (1987) Our Common Future.. (Brundtland World Commission on the Environment and Development, 1987). “ development that meets the needs of the present without compromising the ability of future generations to meet their own needs”  More than 350 published definitions



ASCE defines sustainability as a set of

environmental, economic, and social

conditions - the "Triple Bottom Line" - in

which all of society has the capacity and

opportunity to maintain and improve its

quality of life indefinitely, without degrading

the quantity, quality or the availability of

natural, economic, and social resources.

Environmental Sustainability?



NO Sustainable development without

Environmental Sustainability !!!

Improving the environmental performance by

sustainable planning , design and construction :



Climate and Air Quality



Water supply, quality and treatment



Energy use and sustainable energy options



Recyclable construction materials (Resource

efficient building materials for a sustainable built

environment)!

The dimensions and levels of sustainability;

Sustainable Buildings

An Engineering Perspective

Overview



Why does it matter



Elements of Sustainable Buildings

5 Broad Areas of Application

 Sustainable Sites  Energy and Atmosphere  Indoor Environmental Quality  Water Efficiency  Materials and Resources

LEED Concept and Intent

 (^) LEED is the standard for sustainable design worldwide.  (^) Design and construction practices that significantly reduce or eliminate the negative impact of buildings on the environment.  LEED is a point based system that ranks the sustainability of a building’s design by:  (^) Certified (26 – 32 points)  (^) Silver (33 – 38 points)  (^) Gold (39 – 51 points)  (^) Platinum ratings (52 – 69 points)

Sustainable Sites

 (^) Site Selection  Development Density  Brownfield Redevelopment  (^) Alternative Transportation  (^) Public Transportation  (^) Bicycle Storage and Changing Rooms  (^) Alternative Fuel Vehicles  (^) Parking Capacity  Reduced Site Disturbance  (^) Storm Water Management
