Real-time water monitoring is an easy-to-implement solution that allowed one building to reduce total consumption by 45% in one year, saving over 1.5 million gallons of water and nearly $13,000 on the annual water bill. This session will define water management best practices and demonstrate how to optimize scheduling, identify reduction target areas, and detect faulty equipment.

8. CA TITLE 24 - 2013
Regulations & Certifications Support Efficiency
• Water submetering required for buildings >50K SF
• Water efficiency standards for indoor appliances
• New irrigation standards
ASHRAE 189.1 – 2014
• More stringent water efficiency standards
• WE section rewards appliance efficiency, irrigation, &
water metering
LEED V.4 – 2013
• Up to 2 LEED points for water metering
• Tiered/Volumetric pricing more prevalent

9. The Business Case For Water Management
• Utilities charge for water consumed
AND water exiting through sewer
− BUT, water evaporates from
cooling towers & used for irrigation!
• Transparency into water use
− e.g. Cooling towers, retail, etc.

10. Before Real-Time Monitoring…
The only insight you had into building consumption was a monthly utility bill.

11. Enter A Better Management Experience
Here’s what your monthly consumption looks like in real-time.

15. Water Conservation Measures (WCMs)
• Benchmarking
• Goal Setting
• LEED Guidelines
• Green Lease Requirements
• Preventative Maintenance
• Repair Leaks upon detection
• Work Tickets for Client Issues
• Real Time Energy Program

16. Case Study Example:
The Tower Companies
4,000,000 gal / year
$45,000 / year
100,000 showers

17. Hardware Installation
• Use Existing Metering Infrastructure
• Replace Existing Meter or Add New
Meter
• Ultrasonic Meters

18. THRESHOLDS FOR ALARMS
• > 5.01 GPM during working
hours: 6am - 6pm M-F
• > 1.01 GPM during make up
phase: 4am - 6 am M-F
• > 1.01 GPM during non-
working hours: everything
outside of working and make-
up phase
