Optimize energy consumption and reduce energy costs-
for any kind of buildings.

The system includes a wealth of energy-saving applications for buildings-from offices, hotels, and
shopping centers to hospitals, laboratories, and educational facilities. Reduce more costs by combining
applications according to your building’s characteristics.

VAV Optimum Control

Minimize static pressure with variable air volume (VAV) airflow control.
The supply air temperature is also optimally controlled.

Outdoor Air Cooling

When outdoor air cooling is judged to be effective, take in outdoor air for cooling to achieve energy
savings by effectively using natural energy.

Minimum Outdoor Air Intake

By measuring room CO2 density, minimize outdoor air intake and reduce outdoor air load 40 to 60%.

AHU VSD Control

Control AHU fan VSD without sacrificing a comfortable room temperature.

CO2- Minimizing Control

Control the number of chillers in operation in order to minimize CO2 emissions or total
operating costs of the heat source system.

VWV Control (Variable Water Volume)

Decrease the VSD output of distribution pumps as low as possible, without affecting indoor environmental comfort.

VWT Control (Variable Water Temperature)

Automatically control chiller outlet temperature to achieve more efficient operation of chillers.

Energy Demand Control

Control total building peak load by reducing energy consumption per AHU.

OSS Control (Optimum Start/Stop)

Predict the rise and fall of temperature in order to start/stop air handling units and chillers at the optimal
times and eliminate unnecessary operation.

Duty Cycle Control

To reduce electricity and energy use by air handling units and chillers, operate active air handling units
intermittently while keeping the indoor environment comfortable.

Parking Lot Ventilation

Control ventilation fan air volume to prevent parking lot CO density from rising.

Power Demand Control

Based on estimated power usage from current usage conditions,shut down or restart equipment to avoid exceeding the target power usage.
