Uplifting NABERS with zero capex

Since 2014 Precise Air Group’s Building Performance Optimisation team has worked closely with the BGIS FM team at 2 Parramatta Square to develop a strategy to improve the performance of the building without the need for major capex spend.

In 2014 the BPO team undertook a programme of fine tuning, implementing a range of initiatives including seasonal deadbands and voting techniques at the terminal level, demand control and variable set points at the plants level, closely tuning thermal plants staging with demand control and variable set points reset, and changes to the chiller strategies.

In 2021, the NABERS targets were 5.5 stars for Base Building Energy and 4 stars for Water with zero capex spend. The team achieved these by applying our proactive optimisation model and using our human learning strategies to achieve optimal results.
