Is Your Chiller Using More Energy Than It Should?

HVAC systems often represent one of the largest shares of building energy consumption — yet many organizations don't know the real performance of their chillers.

Key figures

HVAC

Largest building load

Air conditioning systems often represent one of the largest shares of a building's energy consumption.

Months

Degraded performance

A chiller can run at reduced efficiency for months without anyone noticing.

Critical variables

Temperatures, pressures, energy consumption, alarms and running hours — continuous monitoring via GTC and SCADA.

Consumption and risk

Reduced consumption, lower failure risk, better comfort and longer equipment life.

HVAC systems often represent one of the largest shares of a building's energy consumption.

Yet many organizations don't know the real performance of their chillers, when efficiency starts to drop, when an operational anomaly occurs, or what inefficient operation costs.

The Problem

A chiller can continue running for months with degraded performance without anyone noticing.

  • Higher energy consumption
  • Lower thermal comfort
  • Higher operational costs
  • Greater breakdown risk

What Should Be Monitored?

With GTC, SCADA and Industrial IoT you can track chiller performance in real time — identifying efficiency losses before they translate into high costs.

  • Temperatures — chilled water and condensation
  • Pressures — refrigeration and hydraulic circuits
  • Energy consumption — real equipment efficiency
  • Alarms — early anomaly detection
  • Running hours — maintenance planning

Benefits

Continuous chiller monitoring optimizes HVAC operation and reduces energy costs without compromising user comfort.

  • Reduced energy consumption
  • Lower failure risk
  • Better user comfort
  • Longer equipment life
  • Better maintenance management

The ScadaIoT Difference

ScadaIoT combines SCADA systems, Industrial IoT, Energy Management, GTC and HVAC expertise — as a Schneider Electric Alliance Partner — to create complete HVAC monitoring and optimization solutions.

For data centers, hospitals, hotels, shopping centers and technical buildings where energy efficiency and operational continuity are critical.

Conclusion

Knowing whether chillers operate at maximum efficiency is no longer a mystery when continuous monitoring is integrated into GTC or SCADA.

Those who monitor anticipate failures, reduce consumption and ensure thermal comfort with decisions based on real data — not assumptions.

Frequently asked questions

What is chiller monitoring?
It is continuous tracking of temperatures, pressures, consumption, alarms and running hours via GTC, SCADA or IoT — to ensure efficiency and detect anomalies early.
How to identify an inefficient chiller?
Through deviations in chilled water and condensation temperatures, increased energy consumption, abnormal pressures and recurring alarms — visible in dashboards and reports.
Do GTC and SCADA serve the same purpose?
They complement each other: GTC manages the building and comfort; SCADA and Industrial IoT strengthen supervision, alarms and energy performance analysis of HVAC equipment.
Which buildings benefit most?
Data centers, hospitals, hotels, shopping centers and any facility with critical chillers where HVAC consumption represents a significant share of the energy bill.
