Council House 2 (also known as CH2), is an office building located at 240 Little Collins Street in the CBD of 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.〔(Hansen Yuncken ), retrieved 18 January 2010〕 ==Environmental 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 fittings which should consume 65% less energy. The building also houses 48 m2 of solar panels, which provide 60% of hot water, as well as a gas-fired cogeneration plant which provides 40% of the building's overall electricity, with reduced carbon emissions.〔(City of Melbourne ), retrieved 18 January 2010〕 Of the total construction cost of $51 million, $12 million were invested in energy, water and waste innovation. The time for payback is expected to be less than ten years.〔Newman, Peter, et al.: ''Resilient cities : responding to peak oil and climate change'', 2009〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Council House 2」の詳細全文を読む スポンサード リンク
