Kowloon's Zero Carbon Building is a Hong Kong first. In short, it's a complex with zero net energy consumption and zero net carbon emissions – a leader in the movement to achieve energy conservation and reduce greenhouse gas emissions. This site generates on-site renewable energy from photovoltaic panels and a tri-generation system using biofuel made of waste cooking oil. The three-storey circular complex houses an array of exhibition halls that showcase green building technology and design, plus an eco-home displaying eco-friendly furniture such as a bamboo flooring system. There’s also a massive outdoor landscape area too that's home to Hong Kong's first native woodland. There are three guided tour sessions for the public every day.
