All of these measures have resulted in considerable energy savings, particularly due to the sensor- controlled lighting, which is highly effective in cutting energy consumption for a building as large as Chifley. To have a more efficient heating, ventilation and air-conditioning (HVAC) system, the operators removed the less efficient distributed condenser water-cooled air- conditioning system and replaced it with a new, centralised chilled water system, which works to cool the entire building – an improvement on the previous system, which had more than 80 units, and worked on a floor-by-floor basis. This new system also allows for greater control of the HVAC, meaning that there is less potential for energy wastage. Updated technology was also a major contributing factor to the newly efficient Chifley Tower. The operators have upgraded the building management system (BMS), which allows for greater monitoring of the building; and they have upgraded the lift drives and control system, enabling more efficient and safer lift trips for all of the building’s occupants. And they haven’t stopped there – with the general waste management system for the building recently under review, they are also looking to improve this important part of the project in line with the rest of the new features. Reducing a facility’s carbon footprint may be time-consuming, and will require a highly organised team, but it is undoubtedly the right path for ageing buildings. The Chifley Tower green retrofit has been a great success for the operator, its tenants and any future inhabitants of the building, and is testament to the benefits of older, less efficient or unsustainably run buildings undergoing a transformative retrofit.
