Developed and built by Lendlease, Barangaroo South is Australia’s largest urban renewal development project since the 2000 Olympics and one of the most significant waterfront transformations currently underway anywhere in the world. From the outset, Lendlease had a vision to make Barangaroo South one of the most converged, connected smart building projects in the world, proving that intelligent building design can enhance the tenant experience, mitigate energy costs, reduce operations and maintenance expenses while setting new benchmarks for sustainability and overall financial performance. Comprising three iconic commercial office towers and a total built-up area of …3 million square feet in Australia’s.. first carbon-neutral community, International Towers Sydney forms the core of the Barangaroo South development.

  • Capturing building data for current and future analysis

  • Its main challenges were typical for a development that was on a quest for the highest levels of sustainability and operational efficiency.
  • They had to integrate multiple building systems from separate vendors using a variety of protocols into a cohesive whole.
  • Change management had to be facilitated to ensure continuity of operations. They also addressed evolving systems to deliver real efficiencies for each stakeholder’s business requirements.

    The result is that the International Towers Sydney has set a new benchmark for smart building management and innovation in tenant services. What makes this possible is an Open Building System Integration (OBSI) platform based on the iviva software, which provides an unprecedented level of integration between systems and business processes across the three towers. Because it is an open data platform, OBSI serves multiple stakeholders including tenants, building management teams, engineering and commissioning teams and contractors. Easy access to data and control by tenants in real-time.
