130 George Street is a 5-star NABERS energy-rated building with 14 levels of office space owned and managed by Dexus. The building uses seven lifts which were nearing the end of their operational life when an upgrade was initiated in 2015.

Prior to the upgrade, Dexus installed sub-metering of the lift system. This allowed the impact of the upgrade to be measured by providing energy consumption data both before and after the upgrade. Energy Conservation was engaged to verify the energy savings according to the International Performance Measurement and Verification Protocol, providing the expert analysis and interpretation needed to translate the raw data into useful information for the building manager and create financial rewards in the form of Energy Savings Certificates. We found that the upgrade resulted in average annual savings of 83% in energy needed to power the lifts and cool the motor room. Our engineers were able to quantify and verify this reduction in energy consumption to an international standard as well as state the confidence interval and the precision of the annual savings that resulted. Our broad experience managing projects involving numerous interested parties enabled us to smoothly coordinate the supply of information to deliver this project quickly and professionally.
