CH2 is the first commercial office building in Australia to surpass Australia's Green Building Council's six star rating. Major environmental features include a healthy indoor environment with 100% air exchange every 30 minutes. CH2 is also designed as a prototype example to demonstrate that buildings can significantly reduce energy consumption (CH2 operates using 50% less energy than conventional commercial buildings). As a City, Melbourne aims for zero carbon emissions by 2020.

Materials include recycled materials (timber, and concrete), wood windows, and solar hot water heaters, photovoltaics, and wind turbines. Shower towers and phase change materials are used to create cold water which is stored for use in chilled ceilings and beams to keep temperatures comfortable. Sewer water is harvested for non-potable sources.

CH2 is highly decorated as a pioneering green project in Australia. Awards include:
