Shree Sawan Knowledge Park reduces Tenants cooling Complaints along with reduction in energy consumption of HVAC by saving 15% – 20% with reduction in utility billing time through Aunoa Smart control’s wireless utility management solutions.
Challenges

Constant Tenant complaints for Over and under cooling of the offices. High HVAC energy consumption and delay in the billing due to manual operations of the HVAC equipment and data gathering for lead to unsatisfied tenants and higher cost of operations.

Solution

Results
Operation Before Aunoa Smart Control Wireless Building Management System

This HVAC consumption consisted of electrical energy consumed by:

  • Chiller System: Was operated on temperature requirement basis by manually changing the Set point of Chilled Water
  • Air Handling Unit: Turned ON and OFF manually, with constant temperature-based
  • BTU meters readings were taken manually
Operations After Aunoa Smart Control Wireless Building Management System

After Successful Commissioning of Aunoa Smart Control Wireless Building Management System

  • Tenants cooling complaints were reduced by using the Dynamic temperature setpoints as per the operation pattern of the tenants and over usage was put to stop by scheduling the tenants AHUs.
  • As the consumption of Cooling energy was reduced the electrical energy consumption of HVAC high side was also reduced.
  • The HVAC high side was operated completed in Auto without manual intervention.
  • Data from the BTU meters was collected on hourly basis and reports were generated on time for billing.
