The two towers have received a 5-star Green Star rating for both the design and the building, making One Central Park the largest multi-residential building in Australia to receive this certification. The project notably uses hydroponic and heliostat technologies, in which sunlight and vertical gardens play a key role in heating and lighting. Equipped with a low-carbon power plant and an advanced internal water recycling system, the building uses 25% less energy than a conventional building of similar size. The vertical garden covers 50% of the building’s façade and include 250 species of native Australian flowers and plants.
