Civil Engineering for

Sustainable Development

- Sustainability To “sustain” = to “endure” , “maintain” - Sustainable Development “meeting the needs of the present generation without compromising the ability of future generations to meet their needs.” – Brundtland Report In other way = moving ahead while making sure that we can maintain, manage and do justice to the changes we seek and intend to bring about

As Civil Engineers ?

American Society of Civil Engineers -defines sustainability as “a set of economic, environmental and social conditions 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. -Sustainable Development = application of these resources to enhance the safety, welfare, and quality of life for all of society.

“Sustainable Development is now absolutely central to Civil Engineering and we must organise ourselves accordingly” ICE Council 17 December 2002

New Civil Engineer Jan 2003

The 17 Sustainable Development Goals (SDGs) - The relation with the “Environment” ?

• The Earth is One System. • Security, Quality of Life, and

Global Sustainability are all linked.

• Not achieving Sustainable Development might lead to…

• A Planet … • With NO RESOURCES !

* Things to know – Some Terminologies Greenhouse Gases “GHG” :

• Gases in an atmosphere that absorbs and emits radiation within the thermal infrared range.

• The principal forcing greenhouse gases are :

Carbon dioxide (CO2) Methane (CH4) Nitrous oxide (N2O) Fluorinated gases

* Things to know – Some Terminologies

Source: Global greenhouse gas emissions (2012), International Energy Agency

* Things to know – Some Terminologies Carbon footprint

• The total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in tons of carbon dioxide (CO2).

• Can be calculated for a person, building, organization, community or the whole population.

Here are some “SHOCKING” figures …

Shocking statistics-UAE and Gulf ?

*Relation between Civil Engineering & Sustainable Dev. - Civil Engineering as a profession in the 19th century - Thomas Tredgold:

“…the art of directing the great sources of Power in Nature for the use and convenience of man”

- Civil Engineering in the 21st century : “…the art of working with the great sources of Power in Nature for the use and benefit of society”

What can Civil Engineers do?

Sustainable Design

Sustainable Design -is the philosophy of designing physical objects and services to comply with the principles of social, economic, and ecological sustainability. -Reduces the negative impact on the environment and human health, thus improving the performance during a building’s life cycle. -Careful consideration is given to water, energy, building materials, and solid waste.

-Principles of Sustainable Design • Optimizing use of the sun • Improving indoor air quality • Using the land responsibly • Creating high-performance and moisture-resistant houses • Wisely using the Earth’s natural resources

Green Buildings

Example of Green Building?

Green building is NOT just adding a green outlook…

Buildings that are designed, built, renovated, operated and decommissioned in an ecological and resource-efficient manner to:

•protect occupant health

•improve employee productivity

•use energy, water, and other resources more efficiently

•reduce the overall impact to the environment.

in UAE … Green Buildings save about 70% of energy. Green Buildings will save 10milion UED by 2030.

Green Building or not? How to judge ?

LEED - Leadership in Energy

& Environmental Design

- green building certification program - recognizes best-in-class building strategies and practices - To receive LEED certification, building projects satisfy

prerequisites and earn points to achieve different levels of certification.

- We have other rating systems, like National Green Building Standard (NGBS)

Sustainable Construction Why Construction ? because it is the “bad boy industry” www.ciria.org

Sustainable Construction - the optimization of construction activities in a way that does not

have harmful effects on resources, surroundings and living ecosystem.

- It is a way of minimizing harmful environmental impacts of construction projects.

- Construction involves activities like use of building materials from various sources, use of machineries, demolition of existing structures, use of green fields, cutting down of tress etc. which can impact environment in one or more ways.

Sustainable Construction Wastes from demolition of building and structures

• Eliminate – avoid producing construction waste in the first place.

• Reduce – minimize the amount of waste you produce.

• Reuse – reuse the construction wastes in other works.

• Recover (recycling, composting, energy) – recycle what you can only

after you have reused it.

• Dispose – dispose of what is left in a responsible way.

Sustainable Construction Use of Sustainable Building Materials

- Recycled Content

- Natural and renewable

- Locally available

- Durable

- Energy Efficiency

- Affordability

Sustainable Construction Use of Sustainable Building Materials

- Sustainable Aggregates

• Recycled aggregates (recovery of construction and demolition waste)

• Steel slag aggregates and ash

• Aggregates from other waste (Like Plastic, Glass)

Sustainable Construction Use of Sustainable Building Materials

- Sustainable Concrete

• Reduced water content (using super-plasticizer additives)

• Recycling and use of "sustainable" aggregates

Sustainable Construction Use of Sustainable Building Materials

- Sustainable Concrete

• Lower power consumption (self-compacting concretes)

• Lower cement consumption (pozzolanic additives, fly ash)

Examples

Pixel Building, Melbourne, Australia

100% carbon free : carbon produced compensated by renewable energy

Examples

The Change Initiative, Shaikh Zayed Road, Dubai

- a commercial building that received 107 out of 110 points. - The most sustainable building in the world

Examples

Wat Pa Maha Chedi Kaew, Sisaket, Thailand

Examples

Bahrain World Trade Center, Manama, Bahrain

-50-floored, twin tower complex

-1st skyscraper in the world to have incorporated wind turbines into its blueprint.

-three 225 kW wind turbine saves about 15% of the elect. needs

Examples

Khoo Teck Puat Hospital, Yishun Central, Singapore

Finally, ”

• Educate myself, co-workers, clients • Find ways to do existing projects ‘better’ • Track new technologies • Track new/changing environmental legislation • Coordinating sustainability aspects of projects:

ensuring planning starts at the beginning
