EMS have been deployed at:
- 54 A/C properties with shopping centers and markets
- 77 chiller plants
- 262 nos. of chiller

Retrofitted initiative:
Energy Management System (EMS)
- Cloud-based platform with Knowledge-based Artificial Intelligence for energy data analysis and savings.
- Collects operational data via Open Platform Communications (OPC) interface.
- Pilot project carried out in 2020, achieved over 4% savings.
- Full rollout was completed in July 2024.
- Provide energy dashboard for visualization and monitoring.
- A.I. chiller plant optimization to improve operational efficiency.
- Fault detection and diagnostic for operational and maintenance issue identification.
Observed benefits other than energy saving:
Fault detection and diagnostic.
- Identifying operational problems.
- System provides insights for solving the problems.
- Observe abnormal data for maintenance.
- Real time monitoring indoor comfort level.
- Faster response on operational and maintenance issue.
General observations of the retrofitting project:
- During deployment, there was no downtime for operation.
- Chiller plant chilled water supply temperature automatically and dynamically change and reset.
- Chilled water pump speed control reset to reduce pump power and increase the chilled water delta T.
- Cooling tower speed control reset optimized for lower energy usage while balancing chiller efficiency and cooling tower fan speed and power use.
- Additional cooling tower decrease the water to air mass ratio to improve heat rejection to improve chiller efficiency.
