Sustainability
It is not about Green, It is about survival. Sir Norman Foster

The Solar Settlement in Freiburg
A Penthouse on the Sun ShipThe Schlierberg Solar Settlement in Freiburg is the answer to three questions. What is ecologically, solar and energy technologically accomplishable? What is aesthetically expected and what urban planning needs shall be met? Finally, what is economically realistic? These questions were answered and the innovation of the unique design was recognized immediately. The community was a project for the EXPO 2000.

Buildings account for 48% of all Greenhouse Gas Emissions
Chlorinated Fluorocarbons (CFCs) that escape into the atmosphere to degrade the protective ozone layer around the earth
In a culture that has developed a problem of obesity, our buildings have also become obese.
48%
U.S. Energy Power Consumption by Sector
U.S. CO2 Emissions by Sector
76% of all
power plant generated electricity is used just to operate buildings !!

What is Sustainable Design?
a system of development that accommodates human needs without
diminishing natural resources for future generations to meet their own needs.

Perpetual Natural ResourcesVirtually inexhaustible on a human scale
Solar, Wind, Tidal, Gravity
Renewable Natural ResourcesResources that can be replenished through natural processes in a
relatively short time: Water, Timber, Grasses
Non-Renewable Natural Resources Resources that require thousands of years to replenish:
Coal, oil, natural gas

The cost of waste
Construction waste comprises 40% of landfill material
The need for an evaluating matrix:
LEED http://www.usgbc.org/DisplayPage.aspx?CMSPageID=222
How do we verify these claims of green buildings?
Leadership in Energy and Environmental Design
What is LEED?
US Green Building Councilstarted in 1993 is non-profit organization of Architects, Builders,
Realtors, Building Owners, & Environmentalists working together to establish Green Building standards
100 Points plus 10 possible bonus points

Product Life-Cycle
Life Cycle of a Chicken
Product Life-Cycle AssessmentThe process that investigates the energy impact of a product at every stage of it’s life, from development to obsolescence.

Cradle to Cradle Certificationprovides a company with a means to tangibly, credibly measure achievement in environmentally-intelligent design and helps customers purchase and specify products that are pursuing a broader definition of quality. This means using environmentally safe and healthy materials; design for material reutilization, such as recycling or composting; the use of renewable energy and energy efficiency; efficient use of water, and maximum water quality associated with production; and instituting strategies for social responsibility.
If a candidate product achieves the necessary criteria, it is certified as a Silver, Gold or Platinum product or as a Technical/Biological Nutrient (available for homogeneous materials or less complex products), and can be branded as Cradle to Cradle.

Building Life-Cycle Costs
• First cost• Maintenance cost• Energy Consumption cost• Replacement costs
comparable to your automobile
Most Europeans buildings have a far different paradigm on life cycle costs than buildings in the United States.
Buildings in the United States are typically built for investment or sale
Architects know firsthand that most buildings can be designed to operate with far less energy consumption than the average U.S. building does, at little or no additional upfront cost by proper…
• site planning• building geometry• glazing location and properties • material selection• configurations for natural

AIA Committee on the Environment (COTE) Design Awardshttp://www.aiatopten.org/hpb/grid2011.chttp://www.aiatopten.org/
Colorado Court, Santa Monica, California, 2002One of the first housing projects in the United States achieving 100 percent
energy independence. The solar electric panel system integrated into the façade and roof of the building supply most of the peak load electricity demand.

The rampant growth of the green building movement has brought with it the unsavory practice of
“greenwashing.” Greenwashing typically refers to the practice of making unsubstantiated or misleading claims about the environmental benefits of materials, finishes, or systems. This has also resulted in the inaccurate perception that sustainability/green design can merely be an add-on to our buildings rather than through an integrated design approach.
