Powering ARBORIA

A giant, inflatable, walk-in sculpture in the centre of Melbourne city. That’s Ingenuity for life.

Best of all, it’s powered sustainably by Siemens.

After years dedicated to reducing water, waste and energy consumption, Federation Square became a carbon-neutral precinct in 2015.

Some of these savings are a result from both simple and highly innovative initiatives, supported by Siemens.

For example, a co-generation plant underneath Federation Square uses natural gas to generate the electricity that powers the ARBORIA.

Co-generation means the combined production of both electricity and useful heat at the same time. It’s a more thermally efficient use of fuel than electricity generation alone and saves 4470kg of C02 emissions every year, the equivalent to taking 1,000 cars off our roads.

Other sustainability initiatives include solar panels on the roof of Federation Square, a forward-thinking approach to lighting design, as well as a water conservation plan.

A powerful cloud-based digital platform allows Siemens to keep track of how these initiatives are performing – optimizing operations over time and making Federation Square even more energy efficient.
