Water Efficiency
NREL's current water usage. NREL's goal is to reduce water usage by 2.1 million gallons by 2015.
NREL is making significant progress in systematically and cost-effectively reducing water use. Water consumption was 13% lower in FY 2007 as compared to FY 2006. The laboratory is expected to meet the executive order (E.O. 13423) of 16% reduction (2.1 million gallons) by the end of FY 2015 relative to the FY 2007 baseline.
Based on an FY 2007 water audit, NREL plans to implement measures to achieve 45% of the overall 16% reduction in FY 2008 and an additional reduction of 45% of the overall goal in FY 2009. To achieve the balance, NREL will incorporate low-water use intensity features in its planned new construction projects.
Best Practices
NREL has implemented several Federal Energy Management Program (FEMP) Best Management Practices at its facilities, many of which are showcased at its newest facility, the Science and Technology Facility. They include:
- Public information and education programs
- Water-efficient landscaping
- Water-efficient faucets and showerheads
- Low-flow-water-consuming fixtures
- Cooling tower management (increasing the concentration ratio for cooling tower reduces water usage)
- Storm water retention ponds around the building for landscape irrigation
These best practices helped NREL achieve a Platinum level certification for the Science and Technology Facility from the Green Buildings Council under its Leadership in Energy and Environment Design (LEED) Green Building Program.
