One control change.
A lasting difference.
Better performance doesn’t always start with new equipment. Sometimes it starts with making the systems you already have work as they should.
The pumps ran at fixed speed.
The building didn’t.
Primary and secondary chilled-water pumps were running at fixed speeds, regardless of building demand. Zerith identified the issue and developed a demand-led BeMS control strategy — without expensive pipework alterations.
01
Understand the system
Review operation, controls and actual demand.
02
Make a focused intervention
Adjust pump speed through the control strategy.
03
Measure the outcome
Compare the savings with audit and implementation cost.

Pump speed responds to changing demand instead of remaining fixed. Diagram illustrates the principle; it is not measured telemetry.
