Westco BAS – Colorado State Patrol (Castle Rock, CO)
Automation retrofit for improved comfort and energy efficiency

The Challenge
The Colorado State Patrol facility in Castle Rock, CO, was operating with an antiquated VVT automation system that no longer met performance expectations due to hardware failures and system age. They needed to:
- Modernize their legacy VVT system with intelligent BACnet Strato controls
- Improve tenant comfort and climate consistency throughout the building
- Reduce energy consumption and operating costs
The Strato Solution
Westco Systems implemented a complete Strato ecosystem, from the OCN+ server to the end controllers, to bring the facility’s HVAC automation up to modern standards.
This retrofit included:
- Integration of new rooftop units with factory-provided BACnet interface
- Smart space sensors with local setpoint control
- Custom automation strategies to improve reliability and efficiency
This end-to-end deployment ensured complete visibility, faster response, and simplified management across the entire facility
The Impact
The result? Smarter operations, reduced downtime, and measurable energy savings, all powered by Strato’s fully integrated automation solution.
“When it came time to modernize the VVT controls at Colorado State Patrol, Strato Automation’s complete VVT solution was the clear choice. Simple to configure, fast to deploy, and designed for retrofits, it delivered immediate improvements in efficiency and comfort.”
