On Audit and Implementation Costs
An engineering-led energy audit found that the building’s primary and secondary chilled-water pumps were operating at fixed speeds, resulting in unnecessary energy costs.
Zerith developed and implemented a targeted BeMS control strategy that matched pump speed to building demand—without expensive pipework alterations.
This low-risk, low-cost intervention converted engineering insight into measurable savings within 9 months.
