Federation Square is not only one of Australia's most iconic buildings it will soon be 100% Carbon Neutral. A number of large and small scale initiatives have contributed to this target milestone including the farming of honey bees, installation of solar panels and rain tanks, and the popup rooftop garden.

Federation Square's unique heating and cooling systems have also helped to achieve this rating, leveraging off site context and the nearby Yarra River. "We've paid back the cost of this [concrete passive cooling system] in the first 5 years" says Architect and Professor, Donald Bates.
