  1. The Greening of the Rooftop:What the Green Movement Means for Roofing and the Building Envelope James L. Hoff, DBA Center for Environmental Innovation in Roofing

  2. The Greening of the Rooftop What is Green?

  3. What is Green? In the Green Building Movement: Green = Sustainable

  4. Green = Sustainable Other Terms are Subtopics GREEN Energy-Efficient Clean Biodegradable Recyclable Renewable Eco-Friendly SUSTAINABLE SUSTAINABLE Cool Carbon Neutral Bio-Based Environmentally-Responsible Low Carbon GREEN

  5. What is Sustainable? A state that can be maintained at a certain level indefinitely Source: Wikipedia. (http://en.wikipedia.org/wiki/Sustainability)

  6. What is Sustainable? “…meeting the needs of the present without compromising the ability of future generations to meet their own needs." The Brundtland Commission (1) (1) UN World Commission on Environment and Development, “Our Common Future,” April 1987.

  7. The Greening of the Rooftop Who is Green? Who are the Key Influencers in the Green Movement?

  8. Who is Green? • NGOs(Non-Governmental Organizations) • Global Corporations • Governments

  9. Non-Governmental Organizations: (NGOs) • 6% of all U.S. organizations • Employ 1 in 15 Americans • $500 billion annual expenditures • Explosive growth in last 20 years Source: Encyclopedia of Public Health (http://www.answers.com/topic/non-governmental-organization)

  10. Green Building NGOs US Green Building Council American Council for an Energy Efficient Economy Center for Resourceful Building Technology New Building Institute Alliance to Save Energy Indoor Air Quality Association The Green Building Initiative Smart Growth Network Sustainable Buildings Industry Council Environmental Energy & Study Institute Green Roofs for Healthy Cities American Solar Energy Society Energy Efficient Building Association … and many more Source: http://www.greenbuildingpages.com/links/weblinks_sdorgs.html

  11. Global Corporations • Concerned about environmental image • Concerned about long-term growth and asset value • Looking for common denominatorto conduct global business • Looking for competitive advantage

  12. Governments • State & Local Governments • U.S. Federal Government • World Governing Bodies

  13. The Greening of the Rooftop Why Green?

  14. Why Green? • Energy Concerns • Environmental Concerns • Development Concerns

  15. Energy Concerns Accelerating Oil Demand Projected World Oil Demand: 1970 – 2030 (Millions of Barrels Per Day) Source: International Energy Agency “World Energy Outlook, 2006”

  16. Energy Concerns Reliance on Imports Projected US Oil Supply: 1970 – 2030 (Millions of Barrels Per Day) Source: International Energy Agency “World Energy Outlook, 2006”

  17. Environmental Concerns Global Warming Deviation of Global Surface Air Temperature From 1951-1980 Average Source: NASA Goddard Institute for Space Studies

  18. Environmental Concerns Continued Fossil Fuel Reliance Projected Global Energy Supply: 1980 – 2030 (Billions of Tons of Oil Equivalents) Source: International Energy Agency “World Energy Outlook, 2006” (Reference Scenario)

  19. Environmental Concerns Greenhouse Gas Emissions 50 45 40 35 30 25 20 15 10 57% Increase 2005 - 2030 1980 1990 2000 2010 2020 2030 Projected Energy-Related CO2 Emissions (Billions of Tons of CO2 Equivalents) Source: International Energy Agency “World Energy Outlook, 2006” (Reference Scenario)

  20. Environmental Concerns Concerns Beyond Global Warming • Clean Air • Ground-Level Ozone • Air-Borne Particulates • Clean Water • Acidification (acid rain) • Eutrification (algae blooms, “dead zones”) • Other Concerns • Solid Waste • Chemical Toxins • Natural toxins (mold, etc.)

  21. Development Concerns Potential Growth Limits • Ground-Level Ozone • Combined Sewer Overflows • Peak Electrical Capacities

  22. Potential Growth Limits: Ground-Level Ozone VOCs Solvent-Based Construction Adhesives & Sealants Source: US EPA

  23. Potential Growth Limits: Ground-Level Ozone Source: US EPA

  24. Potential Growth Limits: Combined Sewer Overflows Source: Clean Solutions for Omaha (http://projects.ch2m.com/Omaha_CSO/Faq.htm)

  25. Potential Growth Limits: Combined Sewer Overflows Combined sewer systems serve roughly 772 communities containing about 40 million people. Cities with Combined Sewer Systems Source: US EPA

  26. Potential Growth Limits: Peak Electric Usage Florida Power & Light Peak rate is 340% of non-peak rate

  27. Potential Growth Limits: Electrical Usage Per Capita Electricity Consumption: United States v. California (KWH / Year) Source: California Energy Commission

  28. Why Green? Why Green Buildings?

  29. Why Green Buildings? Buildings account for 42% of all U.S. energy consumption & CO2 emissions Buildings 800 600 400 200 0 Residential: 24% Commercial: 18% Transportation Million Metric Tons of Carbon Industry 1940 1960 1970 1980 1990 2000 Source: US DOE 2006 Buildings Energy Data Book

  30. Why Green Buildings? Operating energy accounts for over 85% of total energy usage in buildings Total Energy 80 70 60 50 40 30 20 10 0 Energy (GJ/m2) Operating Energy Initial Embodied Energy Recurring Embodied Energy O 10 20 30 40 50 Building Life (Years) Source: US DOE 2006 Buildings Energy Data Book

  31. The Greening of the Rooftop How will Green Develop? • Science-Based • Systems-Based • Partnership-Based

  32. The How of Green Science-Based / Systems-Based • New Knowledge • Environmental Impact / Life Cycle • Systems Analysis • New Tools • Life Cycle Assessment (LCA) • ISO 14000

  33. The How of Green Partnership-Based • Business • Government • NGOs Working Together

  34. The Greening of the Rooftop What Does It Mean To Me?

  35. Green Buildings What Does it Mean to Me? • For the Designer / Consultant • Expanded role in society • Increasingly complex professional requirements • For the Owner / Manager • Increased income from value-added green buildings • Increasing operational complexity & cost of ownership • For the Contractor / Supplier • Potential new business opportunities • Potential new business competitors

  36. Green What Does it Mean to All of Us? • A New “Accounting” System • A New Level of Complexity • New Opportunities – and Risks
