A site visit to Wests Ashfield Leagues Club was used to identify savings and increase our understanding of the site. Working with the building management system (BMS) contractor and reviewing BMS settings we were able to find areas for improving the efficiency of main power users such as lighting and HVAC. This was achieved by increasing the return air set points on the A/C schedules to a more suitable 22°C. This was an increase of one or two degrees on all AC units, equating to huge annual savings from a minor adjustment.
A comparison of the BMS with the raw electricity usage data in EnergyLink showed discrepancies with some sub-meters. Further investigation of AC unit B1.1 showed that the control on the distribution board had been turned to manual, effectively ignoring the BMS schedule. Instead of operating from 7 AM – 11 PM, it was running 24/7 and using a large amount of electricity. This was quickly and easily rectified for an annual reduction of 38 MWh, with $6,000 in savings on just one sub-meter.

SOLUTION
RESULTS
Since the new car park was completed, the 90 kW exhaust fans were in operation 24/7. Although the car park is open 24/7, it is unnecessary to have the fans running continuously. By correctly enabling the CO sensors in conjunction with the BMS to run only when required, 60 MWh per month was reduced, for annual savings of $115,000.

A BMS is a great way to schedules of various power equipment in a building, but it doesn’t always see when something goes wrong. The real strength of the EnergyLink platform is evident through this example where the BMS suggested normal operations of the A/C and car park fans, but the validation check with EnergyLink showed that it wasn’t performing as expected. With further investigations EnergyLink was proven correct, enabling more efficient operations on site and returning equipment to programmed schedules and controls.
