299 Lane Cove Road, Macquarie Park is an existing three storey building approximately 10 years old. A new chiller was installed to replace the existing air cooled chiller reaching the end of its useful economic life.

The centre zone air conditioning systems on level 2 and 3 had suffered from inadequate heating in winter, mainly due to the highly partitioned office layout. This was rectified by installing a new heating coil associated AHU which was functioning for cooling only, to assist with early morning warm-up of the office. The existing BMCS system was overhauled and variable speed drives for fans and pumps were installed.
Commissioning of both air and water flows as well as the BMCS was also conducted. All these measures promoting energy efficiency, system pressure control, and stability of chiller operation.
