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

managers, public sector &
contractors
3. Why Water Efficiency?
Water: 21st Century oil
Freshwater supply limited
Population/urban growth:
creates large water footprint
Global climate change
Major droughts ahead

Water conservation - the law!

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

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

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.

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!

13. Water Conservation
vs. Water Efficiency
Conservation means less
total use per capita
Efficiency not =
conservation
Behavior modification

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

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. 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
24. Public Sector Actions?
Instill conservation ethic
Price for conservation
Incentivize retrofits
Regulate new buildings
Public education
Develop new supplies
Achieve “20% by 2020”

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

security and cost
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

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?
