Performance Summary

November Results

A sample day in November

This graph, taken from 30 Little Cribb’s daily REF messages, shows the reduction in electricity consumption between 21st November (blue line), a comparable recent day (18th January 2016, pink line), and REF’s expected profile (green line). REF performance monitoring shows a noticeable improvement in October.

Strategies for success

30 Little Cribb’s facility management team worked together with Buildings Alive engineers to improve building efficiency. Significant energy savings were made through implementing strategies such as:

  • Improving efficiency of chillers by implementing a chilled water reset and optimising the chilled water loop, which allowed the chillers to dynamically adjust to an optimum water temperature.
  • Reducing energy wastage through detecting and fixing faults in air handling units, including fine-tuning of static pressure reset strategy, and replacement of faulty sensors and dampers. This prevented wastage of energy through unneeded fan and cooling energy usage.
  • Upgrades of carpark lighting, including changing lights from T8s to more efficient T5s, and putting lighting on sensors to prevent unneeded usage.

Long term performance

While 30 Little Cribb has shown impressive performance in December 2016, these results are even greater when seen over the period since commencement with Buildings Alive services in December 2013.

In this time, 30 Little Cribb has saved a total of $21,604 from their electricity bills, and 107 t.C0₂-e in greenhouse gas emissions. These results can be seen in the graph of energy usage (as compared to baseline performance) since starting Buildings Alive services. Lines in red represent an increase in energy usage compared to baseline, and lines in green represent a decrease, or improvement.
