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

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!

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 in the U.S. & world

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

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.

Water/Energy Nexus
Water supply = energy use
Energy supply = water use
By 2020’s: Not enough water for energy, or enough energy for water!

Water Conservation vs. Water Efficiency
Conservation means less total use per capita
Efficiency not = conservation
Behavior modification
Unintended consequences
“Virtual reservoir”
Reduces peak demand

Australia
20 million people
Most live near the coasts
Except for tropics, country is quite dry
Global climate change moved storm tracks south
Biggest drought in 117-year recorded history 2005 - 2010

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
Product innovations come out of mandatory labeling

Australia: Another Example

Makeup water for cooling towers/toilet flushing
Take water from city sewer, treat on site, reuse, return
Onsite blackwater treatment gaining adherents

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

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

Inhibiting Forces
Water is still cheap
High-water-use lifestyles preferred
Law of unintended consequences
Codes take time to change
Lack of whole systems thinking

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

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

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
Designed by “Whole Systems Engineers”

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?
Will non-green/non-blue buildings & homes pay a market penalty?
