Using BACnet-enabled Lakewood controllers, Scottsdale optimized cooling tower performance and significantly reduced water usage across municipal facilities.
The Results
Key Metrics
- ~15 Million Gallons Saved Per Year
- 25+ Controllers Deployed
- Reduced Water Usage Across Multiple Facilities
The Challenge
Municipal facilities operate complex mechanical systems where water usage can quickly become inefficient especially in cooling tower operations.
Without clear visibility and control:
- water usage increases
- system performance varies
- optimization becomes difficult
The Approach
The City of Scottsdale implemented Lakewood BACnet communicating controllers across their cooling tower systems.
This allowed for:
- centralized monitoring
- real-time performance tracking
- integration into existing building management systems
Custom visualization tools provided clear insights into tower cycles and system performance across facilities.
Built for Visibility
A custom interface was developed to monitor cooling tower performance and integrate directly into the city’s building management overview.
- Tower cycles visualized by building
- Real-time status indicators
- Clear system-wide visibility
“We’ve had tremendous success reducing water usage across our facilities with Lakewood controllers saving an average of ~15 million gallons per year.”
