The secondary pump differential-pressure setpoint is flat for weeks.
The secondary pump differential-pressure setpoint is flat for weeks.
Without a valve-position reset the pumps ride the curve at full ΔP all year — often 20–40% of pump energy.
Implement trim-and-respond ΔP reset on the most-open valve; verify the ΔP sensor location.
How Energy Agent prices a finding
Estimate the extra pump energy from moving more water than the load needs.
Enter positive numbers to see an estimate.
Pump power rises with the cube of flow. At design ΔT the loop needs only (actual ÷ design) of today’s flow, so pump power at design would be that ratio cubed. Energy Agent measures ΔT and pump power from the plant trends.
Screening estimate. Energy Agent measures the real fault hours and load from your trends and prices them at your tariff.
Screening-level estimates; confirm with measurement and verification before capital commitment.
The chilled-water supply setpoint stays flat for weeks while the weather swings.
The condenser-water setpoint never follows the wet-bulb.
Pump status reads on but flow is at or near zero — the pump is deadheading against closed valves.
The chiller is on but CHW supply temperature is above its setpoint by more than the tolerance.
Send twelve months of interval data and a BAS trend export. Energy Agent returns a ranked list of what is wasting money, what each item is worth per year at your tariff, and what to do about it.
