Investing in resources to reduce energy consumption

In the past 12 months, Officeworks opened six new stores whilst at the same time reducing total energy consumption by three per cent from 58,627MWh to 56,793MWh.

This has been achieved through investment in a variety of energy reduction initiatives.  Thirty-three existing stores, for example, were retrofitted with Light Emitting Diode (LED) lighting. In total, 146 stores now have energy efficient lighting across the selling floor.

To better understand and optimise energy consumption, 92 stores had a Building Energy Management System (BEMS) installed. These BEMS have enabled lights and the heating/air-conditioning to be automatically turned on and off at times that align with the operational requirements of the store. The data from the BEMS has allowed heating and air-conditioning problems to be identified and rectified prior to scheduled maintenance or equipment failure.

This year saw Officeworks open its first store with solar panels.  The North Lakes store in Queensland was an Officeworks development that enabled the installation of a 100-kilowatt solar system on the roof to utilise the intense sunlight. The renewable energy generated from the solar panels has supplemented over a third of the store’s energy requirements.
