Sustainable architecture is the architecture that puts emphasis on the minimum impact on the environment by increasing efficiency, innovative use of materials and technology, and focuses on self-sufficiency in terms of energy requirements, etc. Sustainable architecture employs a design approach that is sensitive to the ecological context of the built environment. As the climate crisis deepens, we find ourselves turning to sustainable architecture for answers. All over the world architects have approached sustainable architecture in various different ways. 

Let’s take a look at Australia’s ten most sustainable buildings which are inspiring works of sustainable architecture.

1. The Council House 2, Melbourne | Sustainable Buildings

The Council House 2 in Melbourne was designed by Architect Mick Pearce and his team in collaboration with the City of Melbourne. The building aims to be a holistic design with its occupants as participants. Nature is used as an inspiration for various design elements such as the façade that controls the climate. Technology plays a large role to achieve a design with a six-star rating by the Green Building Council of Australia. It has a gas-powered electricity and heat generation plant as well as solar panels and wind turbines on the roof.
