Enabled by aNIAGARA energy managementframework, the Tridium buildingautomation system softwareCase Study Arup BrisbaneTechnological innovation at a landmark fit-outconstructionSignatory statusDate joined CitySwitch April 2009Tenancy size 5,600 sqmNABERS Commitment ratingWebsite www.arup.comKey outcomesNABERS Energy ratingKey initiatives undertakenOffice fit-out, behavioural change initiatives, sub-metering, lighting retrofit, equipment upgrades,real time energy monitoringArup is the creative force at the heart ofmany of the world’s most prominentprojects in the built environment.

CitySwitch Green Office is a national program working in partnership with Australia’s leading commercial office tenants to improve theirenergy efficiency, thereby reducing the CO2 emissions that contribute to climate change.Bringing staff along thejourneyThe impact of various projectswas significantly increased bycombining technical solutions withsuccessful staff engagement.Complimentary to the Realtimedata visualisation system, one ofArup’s innovative educationprograms was the “Biggest EnergyLoser” competition where officefloors competed with each other toreduce energy consumption.An active environmental volunteerteam also coordinates variousinitiatives within the office such asthe ‘Be an energy hero’ postercampaign.Arup leads in innovativeapproach to energy efficiencyThe energy efficiency journeycontinues however in the meantimetheir efforts were recognised inDecember 2011 when the Brisbanetenancy was awarded the‘CitySwitch National Signatory of theYear’.“In addition to walking the talk,Arup has really stood out his yearfor market innovation.Leveraging existing technologyto generate real time data is noeasy task.
