On a development adjacent the Brisbane River at Newstead, this ground-breaking building is houses the headquarters of Energex, one of Queensland’s largest energy suppliers.

The building houses six storeys of office space, a ground floor retail area and a car park. Cundall provided all building services and ESD for 28,000m² NLA new office building which achieved its target 6-Star Green Star – Office Design (v2) rating.

Key building initiatives:

  • Building façade - double-glazed windows (3100mm high) which admit significant amounts of daylight deep into the interior of the floorplate
  • External shade elements - single and double horizontal and vertical blades, and a perforated screen on the western façade
  • Three separate atria - a fire-engineered solution allows office floor plates to open onto the atria. Skylights over the atria are made of two thin layers of Ethylene Tetrafluoroethylene (EFTE) which are pneumatically inflated into a pillow to provide a lightweight roof which supplies ample daylight to office floors, while keeping the heat out
  • Air-conditioning - the system serving the office areas comprises an active chilled beam design, delivering 100% fresh air to the building
  • Fresh air - there is no recirculation of air, and fresh air quantities have been increased by more than 150% over the minimum requirement
  • Water conservation - over 200 kilolitres of rainwater storage, as well as waterless urinals, flow-restricted water fixtures, and the reuse of fire test water and air-conditioning condensate. A moisture-sensing smart Irrigation system will disable irrigation during rainy periods
  • Solar panels - a 10kW capacity photovoltaic array installed to reduce greenhouse gas emissions
  • Lighting - a very efficient base building lighting system design, incorporating daylight dimming and a building-wide lighting control system
  • Air quality - indoor air quality monitoring to be carried out for 12 months following practical completion
