"Chifley has long held a revered position as a premium office building and retail precinct that is an easily recognised landmark on the Sydney skyline. It now also holds a 4.5 NABERS Energy rating which continues to make it a highly desirable corporate address featuring energy efficient office space.

Chifley Tower Energy Efficiency Upgrade project:

The target 4.5 star NABERS Energy Rating was achieved in January 2015.

The green retrofit program began in 2011 and was completed in 2014. Extensive project works took place in 2012 and 2013.

The project works included:

  • The installation of new central chilled water plant. The building's cooling system was converted from a floor-by-floor, distributed condenser water cooled air conditioning system to a centralised chilled water system. On 15 fully refurbished floors, five tenancy control zones were introduced for greater control of air conditioning supply;
  • Chifley Tower's Building Management System (BMS) was upgraded with a new control system throughout the main plant infrastructure and on floors, including new graphic interfaces for improved monitoring and reporting;
  • Replacement of DC technology lift drives and control system equipment with latest technology;
  • Replacement of car park and back of house light fittings to reduce energy consumption;
  • Installation of C-Bus controlled lighting systems throughout the building to optimise lighting operation times and installation of LED sensor controlled light fittings in some areas to reduce the lighting load significantly;
  • Selection of a new standard tenancy light fitting and lighting layout design to reduce energy consumption and HVAC load; and
  • Review and optimisation of Waste Management systems in place.
