China’s green building demand is mainly driven by multinational companies - to achieve the country’s
energy saving targets local companies need to commit to green building standards too. Nearly half of the world’s new building construction will be in China by 2015, estimates the World Bank. A forecast by
McKinsey Global Institute last year said that China will build a massive 40 billion square feet floor area over the next 20 years adding up to 50,000 new skyscrapers. Energy consumption by buildings in China grew from 10% of the national total in 1970s to 20% in 2006 and is estimated to shoot up to 35% by 2020, according to a study by the Asia Business Council, an association of chief executives of companies with business interests in Asia. The booming construction industry in China has also put unprecedented pressure on water resources. It is estimated that the sector accounts for 16% of total water consumption.
Improving energy efficiency of buildings is crucial for China to realise its national energy strategy. Recognising the importance of ‘green buildings,’ the government has set ambitious energy targets for the building sector. The key target is to cut building energy use in all cities by 50% by 2010 and 65% by 2020, using the average energy efficiency of Chinese buildings in 1980 as the base point. Beijing, Shanghai, Tianjin and Chongqing- four largest cities in China- have targets to cut building energy use by 65% by 2010.
China’s 11th Five Year Plan for 2006-2010 aims to reduce energy consumption per unit of GDP by 20% and considers improving energy efficiency of buildings critical to achieving the target. The government plans to achieve the goal by strictly enforcing energy saving standards on new construction and by retrofitting existing public buildings.
