  • Typeface/font still needs work for subheads
  • Typeface/font still needs work for subheads
  • 1.35°F temperature increase, more evaporation Largest river basin, Murray-Darling, is down to 25% of flow Reservoir inflows near Perth 80% below historical Higher temps/lower flows, more stagnant water, more dengue fever from mosquitoes

    • 2. Cool Water: Blue Is The New Green JERRY YUDELSON • YUDELSON ASSOCIATES • TUCSON, ARIZONA Our Watery Planet
    • 3. Key Take-Aways
      • Water is the next big (green) thing
      • International experience and technology can be adapted
      • Major opportunities: owners, designers, facility managers, contractors and the public
    • 4. Why Water Efficiency?
      • Water: 21st Century oil
      • Freshwater supply limited
      • Population/urban growth: large water footprint
      • Global warming hits water
      • Major droughts since 2006
      • Water efficiency leads to water/energy conservation
    • 5. Water Is the Oil of the 21st Century
      • Resource conflicts
      • Existing water sources fully allocated
      • Next urban/rural battleground
    • 6. Water is the Oil of the 21st Century
    • 7. Freshwater is inherently limited
      • No more water since Adam & Eve
      • Usable freshwater a tiny fraction
      • Much is too polluted to drink
      • Aquifer depletion for water supply
    • 8. Freshwater
    • 9. Water Footprint: Often Hidden
    • 10. Global Warming
      • Much of world supplied in summer with snowmelt
      • Changes in climate = smaller snowpack, larger spring runoff, more devastating floods, reduced summer stream flows, more drought events
      • Water pricing is going to be a huge issue
    • 11. Water/Energy Nexus
      • Hydropower still vital
      • Water supply requires energy
      • Energy supply requires water
      • Not enough water for future energy, or energy for future water!
      Lake Lanier, Atlanta, GA
    • 12. Major Droughts Since 2006
      • In the U.S.
        • Atlanta
        • South Texas (Austin/San Antonio)
        • California
      Murray-Darling, Australia’s Largest River
      • In Australia
        • Every major city
        • Murray-Darling basin
    • 13. Water Conservation vs. Water Efficiency
      • Conservation means less total use
      • Efficiency does not guarantee conservation
      • Behavior modification equally important
      • Some water conservation counter-productive
    • 14. Water Conservation vs. Water Efficiency
    • 15. Your Personal Water Conservation Audit
    • 16.  
    • 17. Australia
      • 20 million people
      • Most live near the coasts
      • Except for tropics, country is quite dry
      • Global warming has moved storm tracks south
      • Biggest drought in 117-year recorded history since 2005
    • 18. Australia
      • Coordinated response by national/state governments
      • $13 billion plan ($650 per person)
      • Water restrictions in all urban areas
      • Product innovations
        • WELS rating is mandatory for product sales since 2006
        • Product innovations
      Rainforest in Tasmania, Australia
    • 19. Australia
      • Plumbing industry front and center
      • Large water utilities recycle water
      • Public is cooperating
      • Desalination is a viable option
      Falcon water-free urinals
    • 20. Australia: Lessons Learned
      • In a crisis, everything’s on the table
      • Easier to do politically
      • System favors (big) long-term solutions
      • Don’t neglect public participation
      • New technology can be mandated
      • Exotic solutions can be tried and evaluated

    • 25. Blue/Green Issues
      • Water shortages/droughts in many states
      • Financial/regulatory incentive programs
      • Green certification programs such as LEED
      • Low-impact development (LID)
      • Rising costs for water supply and sewage treatment
      • Stakeholder concerns; political and regulatory changes
    • 26. Inhibiting Forces
      • Water is still cheap in most areas
      • High water use lifestyles still preferred
      • Unintended consequences
      • Codes need to change

      • New products coming to market
      • Larger questions: water footprint
    • 32. The Future of Green is Blue, But…
      • If you want to score, run to where the ball is going, not to where it is.
      • Ask yourself: how green will the built environment be in 2015? What will be the New Normal?
      • Water-efficient buildings will certainly do better!
