Thirty stories, zero downtime
How we integrated legacy chiller plants and deployed custom closed-loop automation to secure immediate operational efficiency.


Overcoming legacy constraints
Retrofitting an active commercial tower requires absolute precision. Our team mapped the existing legacy networks, identifying critical telemetry gaps before deploying our high-precision controllers without interrupting daily tenant operations.
By programming custom energy-saving logic directly into the new hardware, we established a closed-loop system that continuously balances thermal comfort against real-time grid demand.
