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
Aunoa Wireless Utility Management was started in the month of July 2020 and completed in the span of just one months by end August 2020, the project consisted of Monitoring and Control of various low side HVAC equipment and Energy Monitoring.

The detailed list of equipment undertaken for Wireless Utility Management System is as follow.

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:

  1. Cooling towers system: Turned ON and OFF manually, without temperature based control.
  2. Air Handling Unit: Turned ON and OFF manually, without temperature based control.
  3. 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

  1. Cooling towers system: Turned ON and OFF by auto scheduling and with temperature based dynamic set-point control.
  2. Air Handling Units: Turned ON and OFF by auto scheduling and with temperature based dynamic set-point control.
  3. Ventilation Fan: Turned ON and OFF by auto scheduling.
