    2. 2. Key Take-Aways Water is the next big (green) thing International experience and technology can be adapted for U.S. Major opportunities: builders, owners, project designers, facility© 2012 Yudelson Associates managers, public sector & contractors
    3. 3. Why Water Efficiency? Water: 21st Century oil Freshwater supply limited Population/urban growth: creates large water footprint Global climate change Major droughts ahead© 2012 Yudelson Associates Water conservation - the law!
    4. 4. Water is the Oil of the 21st Century© 2012 Yudelson Associates
    5. 5. Water Will be the Oil of the 21st Century Resource conflicts Existing water sources fully allocated Next urban/rural battleground© 2012 Yudelson Associates

    7. 7. Freshwater is inherently limited No more water since Adam & Eve Usable freshwater a tiny fraction Much too polluted to drink Aquifer depletion for water supply widespread© 2012 Yudelson Associates in the U.S. & world
    8. 8. Freshwater Supply is VERY Limited© 2012 Yudelson Associates
    9. 9. Water Footprint of “Stuff”© 2012 Yudelson Associates
    10. 10. Global Climate Change Much of world (& CA) supplied in summer with snowmelt Changes in climate = smaller snowpack, larger spring runoff, greater flooding, reduced summer stream flows, higher evapotranspiration, less soil moisture, more irrigation required, etc. Water pricing for conservation will be huge issue© 2012 Yudelson Associates
    11. 11. Climate Change – The Largest Risk When it comes to the future of water, "we are, on many levels, completely and totally hosed.” The water cycle itself is changing. As temperatures rise due to climate change, evaporation and precipitation increase, and the atmosphere holds more water. Predictably, the condition should lead to increasingly severe storms and floods in some parts of the world, with prolonged, more intense droughts elsewhere. "We can expect extreme extremes,” which could lead to greater conflicts over water.© 2012 Yudelson Associates - Jay Famiglietti, Director, UC Berkeley, Center for Hydrologic Modeling
    12. 12. Water/Energy Nexus Water supply = energy use Energy supply = water use By 2020’s: Not enough water for energy, or enough energy for water!© 2012 Yudelson Associates Lake Lanier, Atlanta, GA
    13. 13. Water Conservation vs. Water Efficiency Conservation means less total use per capita Efficiency not = conservation Behavior modification Unintended consequences© 2012 Yudelson Associates “Virtual reservoir” Reduces peak demand
    14. 14. Major Droughts Since 2006 In the U.S. In Australia Atlanta Every major city South Texas (Austin/San Murray-Darling basin Antonio) California© 2012 Yudelson Associates Murray-Darling Basin, Australia’s Largest River
    15. 15. Australia 20 million people Most live near the coasts Except for tropics, country is quite dry© 2012 Yudelson Associates Global climate change moved storm tracks south Biggest drought in 117-year recorded history 2005 - 2010
    16. 16. Australia Coordinated response by national & state governments $13 billion plan ($650 per person) Water restrictions in urban areas Product innovations WELS rating mandatory for products since 2006© 2012 Yudelson Associates Product innovations come out of mandatory labeling Rainforest in Tasmania, Australia
    17. 17. Australia Plumbing industry front and center Large water utilities now recycle water to homes Public is cooperating Desalination adopted© 2012 Yudelson Associates as fallback option Water-free urinals
    18. 18. Australia: Another Example “Sewer mining” gaining interest One Bligh Street in Sydney – 30 Story LEED Platinum Makeup water for cooling towers/toilet flushing Take water from city sewer, treat on site, reuse, return Onsite blackwater treatment gaining adherents© 2012 Yudelson Associates
    19. 19. Australia: Lessons Learned In a crisis, everything’s on the table Easier to do big things politically System favors (big) long-term solutions Don’t neglect public participation New technology can be mandated in crisis Exotic solutions can be tried and evaluated© 2012 Yudelson Associates Murray-Darling — Australia’s Largest River
    20. 20. Blue/Green Issues Water shortages/droughts in many states Financial/regulatory incentive programs work Green certification programs such as LEED Rising costs for water supply and sewage treatment Stakeholder concerns; political and regulatory changes© 2012 Yudelson Associates
    21. 21. Inhibiting Forces Water is still cheap High-water-use lifestyles preferred Law of unintended consequences Codes take time to change© 2012 Yudelson Associates Lack of whole systems thinking

    23. 23. What Should the Public Sector Do?© 2012 Yudelson Associates
    24. 24. Public Sector Actions? Instill conservation ethic Price for conservation Incentivize retrofits Regulate new buildings Public education Develop new supplies Achieve “20% by 2020”© 2012 Yudelson Associates
    25. 25. Water Conservation Requires New Pricing© 2012 Yudelson Associates
    26. 26. Where Does This Leave Business? A very dynamic future: much opportunity New technologies, systems, approaches New products/markets Need to address larger questions of supply© 2012 Yudelson Associates security and cost
    27. 27. Bottom Line: Design & Renovate More Water-Efficient Buildings What will Green & WaterSense® buildings look like in 2015? Net zero water use Onsite treatment/reuse NEWater from many sources Far more efficient systems© 2012 Yudelson Associates Designed by “Whole Systems Engineers”
    28. 28. The Future is Green (and Blue), But… If you want to score, run to where the ball is headed, not to where it is. Ask yourself: what will built environment look like in 2020? What will be the Next Normal? How can we get there? Spain Wins FIFA World Cup 2010© 2012 Yudelson Associates Will non-green/non-blue buildings & homes pay a market penalty?
