Challenges
The mall had no Building management system installed which lead to manual operation of all the utilities. Record Keeping & Data Analysis was getting difficult which lead to high engineering operating costs. This inability to monitor and control also gave rise to high electrical energy consumption by HVAC equipment.
Solution
A detailed analysis was carried out and the below solutions had been provided and achieved 15% to 25% savings on HVAC with Optimization on the Manpower on the operations front.
Project
The detailed list of equipment undertaken for Wireless Utility Management System is as follow.
Sr. No | Equipment Name | Quantity | |
Monitoring and Control | Monitoring | ||
1 | DX Type Air Handling units | 16 |
|
4 | Cooling Towers Pump | 1 |
|
5 | Cooling Towers Fans | 1 |
|
7 | Ventilation Fans | 1 |

Results
Conditions before Aunoa Utility Management System
Before installation of Aunoa Wireless Utility Management System the electrical consumption was
| Electrical Energy Consumption ( kWh) |
Total HVAC Consumption (Average Monthly) | 39500 |
This HVAC consumption consisted of electrical energy consumed by:
- Cooling towers system: Turned ON and OFF manually, without temperature based control.
- Air Handling Unit: Turned ON and OFF manually, without temperature based control.
- Ventilation Fan: Turned ON and OFF manually.
Conditions after Aunoa Utility Management System
After Successful Commissioning of Aunoa Utility Management System the HVAC consumption was brought down to
| Electrical Energy Consumption ( kWh) |
Total HVAC Consumption | 30000 |
Generating a saving of 9500 kWh units which is 24% reduction in Electrical Consumption than previous year.
This Savings was achieved by
- Cooling towers system: Turned ON and OFF by auto scheduling and with temperature based dynamic set-point control.
- Air Handling Units: Turned ON and OFF by auto scheduling and with temperature based dynamic set-point control.
- Ventilation Fan: Turned ON and OFF by auto scheduling.
