Bendigo Community Health Services – HVAC

Bendigo Community Health Services (BCHS) is a not-for-profit organisation that provides a range of health programs and services in local communities. In 2014 CarbonetiX was asked to review the technical submission for a like-for-like replacement of a chiller at the Eaglehawk site. Considering the addition of the separate systems the 135kW chiller proposed would have been significantly oversized, resulting in a very small load on the new chiller(~60%) decreasing it’s running efficiency incurring higher capital expense and increased ongoing electricity costs. This scenario would have done little to improve the comfort of the building for the occupants.


  • Analyse the existing technical submission regarding the chiller replacement
  • Write a new specification allowing Design and Construction solution to facilitate efficiency improvements
  • Assist in the tender review process and recommend the best long term value for money options for BCHS
  • Vet thermal load calculations that were used to determine the optimal size of the system
  • Reduce onsite energy consumption, whilst providing comfort conditions that were suitable for the operation of a health care facility
  • Meet project deadlines as system was to be installed in the middle of summer
  • Auxiliary air conditioning organised to provide temporary cooling to patients and practitioners
  • Removal and disposal of redundant equipment and full modification of the existing system


The new VRV air conditioning system reduced energy consumption significantly and provided balanced air conditioning to the building’s occupants. During the installation, the duct work was found to be in poor condition and required unexpected modifications to improve the performance of the overall system. CarbonetiX worked with the mechanical contractor to address these issues. During the project the following results were achieved:

  • Energy consumption at the site reduced
  • Equipment operational on time causing minimal disturbances to occupants
  • Patients and staff satisfied with the air conditioning being provided in each area
  • Built strong relationships with the client and mechanical contractor

Maxine Plant, Manager Fleet and Facilities said: “We found CarbonetiX to be a wonderful asset as the project managers/consultants on this project due to their collaborative approach and the guidance they offered. Peace of mind for the client was gained from the professional and courteous approach CarbonetiX took to the project.”
