NATURAL CAPITALISM
“The next Industrial revolution, like the first one, will be a response to changing patterns of scarcity. It will create upheaval, but more importantly, it will create opportunities.”create opportunities.”
Natural Capitalism: Creating the Next Industrial Revolution, Paul Hawken

WHAT IS SUSTAINABLE DESIGN
“Sustainable Design is a
design philosophy that
seeks to maximize the
quality of the built
environment, while environment, while
minimizing or eliminating
negative impact to the
natural environment.”
Jason McLennan - The Philosophy Of Sustainable Design
![Page 6: C:\Documents And Settings\Dbecker\My Documents\Presentations & Articles\21st Energy Fair\2010 Mrea Energy Fair Presentation](https://reader034.fdocuments.us/reader034/viewer/2022052522/554951b4b4c905fc4e8b4b75/html5/thumbnails/6.jpg)
SHAPING SUSTAINABLE DESIGN
1. Regionalism: recognizing local conditionsfor materials, sun, wind, light and water.
2. Solar income: Use of any energy source that is renewable and currently available.
3. Old solar savings: Nonrenewable that when used release centuries of carbon when used release centuries of carbon dioxide as in coal and petroleum.
4. Look to nature to provide solutions for comfort.
5. Design as adoption to place and climate instead of technological control.

WHY SUSTAINABLE DESIGN
• Took thousands of years for our population to reach one billion
• Taken less than a century to reach six billion
• Predicted to grow in this century to ten billion
• Half buildings in USA will be built 2000 - 2030 • Half buildings in USA will be built 2000 - 2030 Prof Arthur C Nelson

DESIGNING SUSTAINABLY
1. Whole system thinking
2. Team work
3. Shifting the design curve
4. End-use/least-cost considerations
5. A true commitment

LIGHT
Daylighting:Is the choice, art, practice or science of using indirect natural lighting to illuminate the interior of buildings, reducing the need for electric lighting.
Cool Daylighting:Cool Daylighting:Is the successful application of daylighting using holistic design strategy that uses daylight to reduce the need for electric lighting, balances the need for quality light without causing unwanted glare and reduces the need for space cooling.

• East-west axis gives greater access to penetrating daylight with reduced heat gain, but more difficult to manage
• Long north-south axis creates greater exposure to low sun with more heat gain.

Management
• Develop appropriate control strategies
• Utilize building geometry & spatial arrangements
that promote daylighting distribution
• Configure building to maximize number of spaces utilizing daylighting

LIGHT
Toplighting
• Light the space, not the task
• General rule: 5% of ceiling area
• Avoid direct skylight & sunlight on critical tasks
• Bounce daylight off surfaces
• Bring daylight in from above to get deeper into space• Filter sky light
• Maximize ceiling heights

LIGHT
Sidelighting
• Differentiate view windows from daylight windows
• Balance amount of light across a space
• Consider integrated approach with toplighting

THE CHANGE
“Every few hundred years in Western history there occurs a sharp transformation. Within a few short decades, society – its world view, its basic values, its social and political structures, its arts, its key institutions – rearranges itself. And the people born then cannot even imagine a world in which their grandparents lived and into which their own parents grandparents lived and into which their own parents were born. We are currently living through such a transformation.
Peter Drucker, Post-Capitalist Society
