3. Energy Exchange : Federal Sustainability for the Next Decade 3 Why should you care?

4. Energy Exchange : Federal Sustainability for the Next Decade 4 Why should you care? “One third of all counties in the US will face high risk of water shortages by the middle of century.”

5. Energy Exchange : Federal Sustainability for the Next Decade Federal Water Efficiency Mandates Executive Order (EO) 13423 Potable water use intensity (WUI) reduction through FY 2015 Energy Independence and Security Act 2007 Comprehensive water evaluations EO 13514 Extends potable WUI through FY 2020, adds new water use reduction for ILA* water use EO 13693 Supersedes EO 13514 and EO 13423, extends reduction requirements to FY 2025 5 *ILA = industrial, landscaping, and agricultural

6. Energy Exchange : Federal Sustainability for the Next Decade 6 Water Terms Potable water: Sufficient quality and permitted for human consumption ILA water: non-potable from freshwater sources used in industrial, landscaping and agricultural applications Alternative water: non- potable water NOT supplied from freshwater

7. Energy Exchange : Federal Sustainability for the Next Decade 7 Water Terms – Alternative Water Rainwater HarvestingGray WaterCondensate CaptureProcess DischargeWastewater Reclaim Applications Irrigation Cooling Tower Make-up Toilet/Urinal Flushing Vehicle Wash Industrial applications

8. Energy Exchange : Federal Sustainability for the Next Decade 8 Facility Water Cycle Potable Water ILA Water Non-potable Alternative Water Leaks

9. Energy Exchange : Federal Sustainability for the Next Decade Planning for Federal Sustainability in the Next Decade Reduce potable WUI 2% per year through FY25 from a FY07 baseline Reduce industrial, landscaping, and agricultural (ILA) water use by 2% per year through FY25 from FY10 baseline 9 EO 13693 Water Provisions

10. Energy Exchange : Federal Sustainability for the Next Decade 10 Potable Water Use Intensity (WUI) Reduction  WUI reduction: gallons per square feet of facility space  2% per year from FY07 through FY25

11. Energy Exchange : Federal Sustainability for the Next Decade 11 ILA Water Reduction 30% reduction  ILA volumetric reduction: gallons  2% per year from FY10 through FY25

12. Energy Exchange : Federal Sustainability for the Next Decade Onsite pond for irrigation 12 Quiz – What is the water type? Onsite potable well for dust suppression Process discharge water in cooling towers POTABLE ALTERNATIVE ILA

13. Energy Exchange : Federal Sustainability for the Next Decade Planning for Federal Sustainability in the Next Decade Construct and renovate Net Zero Water buildings 13 EO 13693 Water Provisions EO 13693 Definition: Net zero water building means a building that is designed, constructed, or renovated and operated to greatly reduce total water consumption, use non-potable sources as much as possible, and recycle and reuse water in order to return the equivalent amount of water as was withdrawn from all sources, including municipal supply, without compromising groundwater and surface water quantity or quality.

14. Energy Exchange : Federal Sustainability for the Next Decade Reduce freshwater demand and increase efficiency Maximize alternative water sources 14 Net Zero Water Building Hydrologic Cycle Facility Water Cycle

15. Energy Exchange : Federal Sustainability for the Next Decade Planning for Federal Sustainability in the Next Decade Install water meters – Large water processes > 1,000 gallons per day – Irrigated areas > 25,000 square feet – All buildings > 1,000 gallons per day 15 EO 13693 Water Provisions

16. Energy Exchange : Federal Sustainability for the Next Decade Planning for Federal Sustainability in the Next Decade Develop a water balance 16 EO 13693 Water Provisions

18. Energy Exchange : Federal Sustainability for the Next Decade 18 FEMP Resources: Alternative Water Maps Rainwater Harvesting Regulations Map

19. Energy Exchange : Federal Sustainability for the Next Decade 19 Rainwater Harvesting Regulations – State Level

20. Energy Exchange : Federal Sustainability for the Next Decade 20 Future Map – Rainwater Harvesting Potential for Irrigation* *Map is preliminary

21. Energy Exchange : Federal Sustainability for the Next Decade 21 Future Map – Air Handling Condensate Capture Potential* *Map is preliminary

22. Energy Exchange : Federal Sustainability for the Next Decade 22 How effective are ESPCs in water efficiency? Observations: Only 3% of the total investments include water efficiency Water cost accounted for 9% of the total utility cost for federal agencies in FY12

23. Energy Exchange : Federal Sustainability for the Next Decade 23 Steps to Expand Water Efficiency in Financed Projects 1. Screen What is the potential for water efficiency? 2. Require Expertise Is the contractor qualified? 3. Conduct a Water Balance What are the primary water uses? 4. Specify Technologies Are you choosing the right technologies?
