  1. Sustainability ARCH 3311 - Fall 2009

  2. 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

  3. In a culture that has developed a problem of obesity, our buildings have also become obese.

  4. 48% U.S. CO2 Emissions by Sector U.S. Energy Power Consumption by Sector 76% of all power plant generated electricity is used just to operate buildings !! Fact Sheet on Architects and Climate Change, American Institute of Architects http://aia.org/aiaucmp/groups/aia/documents/pdf/aias077675.pdf

  5. The cost of waste

  6. Construction waste comprises 40% of landfill material

  7. Environmental Design Green Energy Efficient Sustainable Low Energy

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

  9. Perpetual Natural Resources Virtually inexhaustible on a human scale Solar, Wind, Tidal, Gravity Renewable Natural Resources Resources 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

  10. Sustainable Design Environmental Sustainable Design Economic Social

  11. How do we verify these claims of green buildings? The need for an evaluating matrix: LEED http://www.usgbc.org/DisplayPage.aspx?CMSPageID=222

  12. What is LEED? Leadership in Energy and Environmental Design US Green Building Council started in 1993 is non-profit organization of Architects, Builders, Realtors, Building Owners, & Environmentalists working together to establish Green Building standards

  13. 80 Platinum 60 Gold 50 Silver 40 Certified Green Building Rating System™ 100 Points plus 10 possible bonus points

  14. California Academy of Sciences, San Francisco Architect: Renzo Piano, 2008

  15. Green roof over eight level parking structure

  16. Editt Tower, Singapore (proposed) Architect: Ken Yeang, speaking at SPSU Feb. 15, 2010 !!!

  18. Product Life-Cycle

  19. Life Cycle of a Chicken

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

  21. Life-Cycle Assessment The process that investigates the impact of a product at every stage of it’s life, from development to obsolescence

  22. Cradle to Cradle Certification provides 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.

  23. Building Life-Cycle Costs • First cost • Maintenance cost • Energy Consumption cost • Replacement costs 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

  24. 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 heating, cooling, ventilation • daylighting

  25. AIA Committee on the Environment (COTE) Design Awards http://www.aiatopten.org/hpb/grid2008.cfm http://www.aiatopten.org/hpb/grid2007.cfm http://www.aiatopten.org/hpb/profiles2006.cfm Sample Project Corporate Headquarters http://www.aiatopten.org/pdf_2006/MackyMitchellAssociates_Alberici.pdf

  26. Google’s Energy Initiativeshttp://www.google.com/corporate/green/energy/ Google Inc. says it will spend hundreds of millions of dollars to develop renewable energy as part of an ambitious plan to clean the environment and reduce the company's own power bill.

  27. Colorado Court, Santa Monica, California, 2002 One 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. Architect: Pugh + Scarpa

  29. 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.

  30. Questions - Sustainability • What is Sustainable Design • What are the three elements that interdependently create good sustainable design • What are three renewable resources • What are three non-renewable resources • What are three perpetual resources • What percentage of electrical power produced in the US is consumed by buildings? • What % of energy use and greenhouse gasses are attributed to buildings? • What is Greenwashing? • What is product life-cycle? • What is the Cradle to Cradle initiative? • What are typical building life cycle costs? • What % of waste in landfills is construction waste? • What does the acronym “AIA COTE” stand for? • What does the acronym “LEED” stand for? • What is the highest LEED certification level? • What are the 5 LEED categories that are evaluated and assigned points? • What does the acronym “USGBC” stand for?
