Council House 2 (also known as CH2), is a green office building located in the CBD, in Melbourne, Australia. It is occupied by the City of Melbourne council, and in April, 2005, became the first purpose-built office building in Australia to achieve a maximum Six Green Star rating, certified by the Green Building Council of Australia. CH2 officially opened in August, 2006.

[edit] Environmental savings and features

Comparing to a building with a Five Green Star rating, CH2's emissions will be 64% lower. When compared to the existing Council House next door, it is expected to:

  • reduce electricity consumption by 85%
  • reduce gas consumption by 87%
  • produce only 13% of the emissions
  • reduce water mains supply by 72%

Features include new LCD computer monitors, which will consume 77% less energy, and new T5 light fitings which should consume 65% less energy. The building also houses 48m2 of solar panels, which provide 60% of hot water, as well as a gas-fired co-generation plant which provides 40% of the building's overall electricity, with reduced carbon emissions.
