Council House 2 (CH2) was piloted in an effort to provide a working example for the local development market.
It was the first new commercial office building in Australia to meet and exceed the six star rating system administered by the Green Building Council of Australia. Equally important to its environmental features is that it provides 100% fresh air to all occupants with one complete air change every half hour. The benefits of superior indoor air quality and conservative estimates on energy costs will see the building pay for all its innovation within five to ten years. CH2 was designed to be a holistic and all-inclusive system with its occupants as participants. The design follows a model that promotes a more interactive role between the city and nature, acting more like an ecosystem in which all parties depend on each other.
