����Using design to build a sustainable future

����More than 40 international experts and local designers gathered at a UNESCO Creative Cities Network Conference workshop yesterday��Dec.7���� discussing whether humans were on the right track in realzing urbanization and how city design could build a sustainable future.

����Wu Zhiqiang�� chief planner of the 2010 Shanghai Expo and a Tongji University professor of architecture�� said the case studies and experiments at the expo proved that design could create a better city.

������During planning for the expo in 2004�� many ideas were inconceivable for us�� such as natural ventilation�� solar electricity generation�� multifunctional shading�� optimization of daylight�� Huangpu River water treatment and building nine more metro lines in just six years���� said Wu.

����He said public transport played a crucial role in the most crowded Chinese city��s expo and a city��s future would rely heavily on public transport.

����Wu mentioned expo pavilions that had been transformed from old factories�� saying that urbanization was not just about seeing the future or simply demolishing [buildings] but also about preserving history.

������China��s urbanization has a greater impact on energy consumption than a growing economy and China should never copy Western countries�� past experience in urbanization because developed countries top the world in equivalent carbon emssions per capita���� Wu said.
