Step-by-step explanation:
The name of the award-winning mixed-use building located in Sydney, Australia, that includes residential apartment towers and a retail shopping center and was awarded a 5-star green star-Multi Residential Design Certified Rating by the Green Building Council of Australia is One Central Park, Sydney.
One Central Park is notable for its eco-friendly features such as hanging gardens, a cantilevered heliostat, a low-carbon power plant, and a water recycling plant. It uses gray water for laundry, bathrooms, and watering green areas. Additionally, the rooftop reflector panels direct sunlight to shady areas of the park during the day, and at night, the building transforms into an LED artwork called Sea Mirror, designed by Yann Kersale. The gardens, designed by Patrick Blanc, cover 1,120 square meters and consist of over 35,200 plants of 383 different species, including native Australian plants.
