What is Sustainability ?
– the Brundtland Report, 1987
World Commission on Environment and Development
Sustainability is…
“development that meets the needs of the present without compromising the ability of future generations to meet their own needs”
What is Sustainability ?
• Releases billions of pounds of toxic waste into air, water and soil every year
• Creates materials that cause concern by future generations to their quality of life
• Produces large amounts of waste
• Requires endless regulations to simply regulate the rates of damage of points above
Industrial Revolution:
• Development of ‘Agenda 21’ at the World Summit – June 13 of 1992
• representatives stood for 90% of Earth’s population.
• comprised single largest gathering of heads of state in history of international diplomacy
What is Sustainability ?
Agenda 21 is best grouped in 6 topic categories:
1. The quality of life on earth
2. Efficient Use of the Earth’s Materials
3. The Protection of our Global Commons
4. The Management of Human Settlements
5. Chemicals and Management of Waste
6. Sustainable Economic Growth
What is Sustainability ?
‘Agenda 21… + 10’
“There were many fine achievements on paper at Rio but what has happened on the ground since Rio is all too little"
-Dr Norman Myers independent conservation scientist
What is Sustainability ?
‘Agenda 21… + 10’• 1.2 billion people lack access to clean drinking
water• 35% of world's fisheries suffer from declining
yields• EU nations have yet to achieve waste and
materials reduction targets
WWF, 2003
What is Sustainability ?
Sustainability Drivers
• Informed public demand • Positive recognition for leaders• Best long-term solution • Environmental legislation• Increasing prices for resources
(i.e. energy, water, fuel, wood etc.)

Canadian Government:
2008 EcoACTION budget highlights - to ensure cleaner, healthier environment:
• $66 million over 2 years to set up regulatory framework for industrial air emissions
• $10 million over two years for research and analysis on biofuels
• Extending GST/HST relief to land leased to situate wind/solar-power equipment for electricity production

continued…
• $21 million over two years to make environmental law enforcement more effective
• $12 million over two years to enhance law enforcement within Canada’s National Parks
• $250 million for full-scale commercial demonstration of carbon capture and storage in the electricity sector
Market for Sustainability
In Ontario:
• Government provided budget to help provinces, territories, municipalities
• 2007 $962 million • in new and existing infrastructure• Upgrade Ontario’s highway system (Hwy 407,
Hwy 404, and Hwy 7 specifically) • Alternatives to driving (i.e. public transit)

Defining Traditional Engineering
In 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
What changed?
Traditional Engineering:Maximizing utility while minimizing
the cost to the
Maximize social benefit while minimizing ecological impact
Shift in Engineering Mindset:
client
But…How do We Track Progress?
• SOCIAL EFFECT:
Community activities, employment rates, immigration...
• ECONOMIC ACTIVITIES: Business growth, employment rates, inflation…
• ENVIRONMENTAL EFFECTS: - Beach closures, smog warnings, environmental contaminations, endangered wildlife…
- Birth defects, death rates, severe asthma attacks…
How do we track changes to these factors?

Sustainable Development
3. What Professionals can do
4. Useful Tools & Incentives
• Be aware of issues and impactsInherently includes well-being of environment
• Comply and go beyond minimum requirement• Involve public and communities in decision-
making• Set our mindset to doing what is right• Even when appears to be a more difficult
process - it is a step in the right direction
Must change the way people think about sustainability!
Designing Towards Sustainable Development
• Step back from “business as usual”
• Find ways to work with nature
• Lessen environmental impact
• Save energy, resources
• Build on Small Successes – piloting
• Spread the word - Market your capabilities to both existing and new clients
Designing Towards Sustainable Development
The Challenge… goes beyond just the money!
Design project to: • Reduce material and energy use• Use renewable energy resources• Maximize lifespan of structure• Reduce construction waste generated• Reduce/eliminate hazardous waste
generation• Minimize maintenance and services
required
What Professionals Can Do
Most importantly…
Design project to either reduce or eliminate:
•greenhouse gas emission•Use of ozone depleting substances•Key air pollutants•Indoor air pollutants
What Professionals Can Do
Consider all costs beyond $$$, including:• Energy• Water/sewage• Chemical/materials• Maintenance and operation• Life span and replacement cost
What Professionals Can Do
Sewage Treatment Plant • Digester gas for energy• Heat exchanger on sewage effluent• Heat recirculation from transformers,
blowers• Irrigation using plant effluent
… some examplesWhat Professionals Can Do … in projects
Urban Development: • Redevelopment of brownfield sites• Pervious pavement in parking lots• Residential cisterns• Constructed wetlands and ponds
What Professionals Can Do … in projects… some examples
Transportation: • Public transit emphasis• Pedestrian, bicycle friendly• Animal/bird crossing culverts• Reuse of materials
What Professionals Can Do … in projects… some examples
Architectural and Building Systems: • Consider sun, wind and daylight• Maximize reuse of structures & materials• Use natural ventilation• Consider low flow toilets and urinals• Consider solar systems to power outdoor
lighting, i.e. parking lots, walkways• Use automatic lighting controls that respond to
available daylight
What Professionals Can Do … in projects… some examples
• Research and learn about new products and technologies
• Learn from past project experiences• Stay up-to-date through:
• Conferences & Events• Media
Keep yourself up-to-date:

Canada NC 1 Guide
The steps for staying on track include:
• Documentation: as early as possible and
maintain it
• Update / Monitor Sustainability Checklist: have a
clear picture of progress on sustainable goals
• Energy / Cost Models: Use energy and cost
models as design tools
Eliminating the Myth- “Green costs more”
Budget Pointers:
NOT … “How much more will it cost?,”
BUT RATHER…“How will we do this?”
• Ask early in the project, and considered at
every step of design and construction• Establish team goals, expectations &
expertise• Include specific goals in the Program• Align budget with program• Stay on track with design and construction
Eliminating the Myth- “Green costs more”
Eliminating the Myth- “Green costs more”
But it’ll take a collaborative effort to get to where we need to…
Owners, planners, designers, builders, educators, decision-makers, regulators, must all find means to work together towards a common goal.
