The surge in cement production and the broad use of coal-fired electricity generation have also made China the biggest CO2 emitter. The increasing environmental concern has motivated China to make a substantial effort to decrease energy consumption and reduce carbon emission. Despite the effort, China is still at the primary stage of a zero carbon community design. China’s limited environmental progress is partially attributable to the urban planning method that it has adopted. Following the pattern that the US used in the last century, China uses the mono functional urban method. The core characteristic of mono functional urban plan method is to segregate land use through zoning: each geographic area can only be used for one purpose such as residential or commercial use. Adopting a zero carbon community model is essential to any successful environmental plan for China. From 2000 to 2010, the Chinese government invested 18 billion yuan (2.3billion U.S. dollars) to build the Shanghai World Expo Park. With the end of the 2010 World Expo, most of the pavilions were removed leaving a large expanse of empty land waiting to be redeveloped. The purpose of my thesis is to create a plan for the Shanghai World Expo Park that incorporates a zero carbon community. As a model, I rely on Toronto’s success in the redevelopment of its harbour. My design adopts the following to achieve a zero carbon community: z Utilizing a balanced transportation system to reduce transportation pollution. z Increase efficiency by adopting a mixed use community design (in contrast to the mono functional urban model). z Increase the efficiency of cooling and heating systems by adopting low carbon energy district energy. z Diminish underground water waste by encouraging rainwater harvesting. iii Table of Contents List of Figures …………………………………………………………………….…………. vi List of Tables .…………………………………………………………………..………….... xiv Acknowledgements …………………………………………………………………….….. xv Chapter 1 Introduction ………………………………………………………………….…….1 1.1 China’s energy crisis …………………………………………………………..….2 1.2 Shanghai’s environmental problem ………………………………………..…..….5 1.2.1 The rapid growth of motorized vehicle………………………………..………...….6 1.2.2 Mass produced single-use community …………………..…….............................7 1.2.3 Broad use of coal-based energy .……………………………………….....…....….8 1.2.4 Low efficiency heating & cooling systems ……………….……………..……...….9 1.2.5 Overexploitation of underground water .…………………………..…..……...….10 1.2.6 Conclusion………………………..………………………………………………………...….11 Chapter 2 Case study and guide line……………………………………………….……...12 2.1 Toronto – a sustainable city….…………………………………………………………………12 2.2 Similarities between Toronto and Shanghai ….………………………………………………13 2.3 Balanced transportation ….…………………………………………….………………………19 2.4 Mixed-use community ….……………………………………………….…………..…………28 2.3.1 The Distillery District ……………………………………………….….…………..30 2.3.2 West Don Lands …..………………………………………………..….…………..34 2.5 Building design requirement ……..…………………………………..….…….………….…..40 2.6 District heating & cooling, renewable energy ……………………..….………….…...……..42 2.7 Rainwater harvesting ...……………………………………….……..….……...…………..…..45 2.8 Summary ……………………………………………………………..….…………..…...……..47 iv Chapter 3 Site Analysis …………………………………………..………………………… 48 3.1 General information …………………………………………………………………………… 48 3.2 Geography …………………………………………………..……………………………….… 49 3.3 Site History….………………………………………………..…………………………………. 51 3.4 General plan of the Shanghai Expo Park ……………………..…………………….………. 54 3.5 Transportation system ……………………..…………………………………….…………… 59 3.6 Land use after the 2010 Expo ……………..……………………………………..………...… 61 3.7 Site and its relation to adjacent buildings ..…………………………………………..……… 65 Chapter 4 Design goal …………………….…………………………………………………66 Chapter 5 Practical Application…………………….…………………………………..…. 68 5.1 Basic concept ………………..…….……………..………………………...……………. 69 5.2 Develop balanced transport…….…………………………………….……………...…. 72 5.2.1 Removing barriers and making connections ………………….………….……. 72 5.2.2 Improve public transportation ………………………………...………..……... 74 5.2.3 Develop bicycle transportation ………………………………...………..…........ 76 5.2.4 Pedestrian friendly nexuses ………………………………...………..…....... 77 5.3 Develop attractive open space …………………….…………………..………..…..... 78 5.3.1 Positive green space ………………………….……………...………….…........ 78 5.3.2 Enhance riverside experience ……………….……………...………….…........ 82 5.4 Attractive mixed-use community ……………….……………...……………....…........ 83 5.4.1 Proper city block scale…………………...……………...……………....…........ 83 5.4.2 Function analysis …………………...…………………...……………....…........ 85 5.4.3 Building design requirement ……...………………….....………....…...................... 92 5.4.4 Sustainable material ……...………………….....……………....………................... 94 5.5 Sustainable technique………...…………………........……....………….…................ 95 5.5.1 District energy ……...………………….....………….……....………….…......... 95 5.5.2 Rainwater harvesting ………………….....………….……....…….…....................... 97 Chapter 6 Conclusion of the study ……………………………………….……………….98 6.1 Research summary ……………………………………….………………………….….…...98 6.2 Area of future research ………………………………….…………………….…….….…….99 6.3 Conclusion of the Study …………………………..…….…………………….……….….…101 6.5 Epilogue …………………………..…….……………………………….…….……….……..102 Bibliography ……………………………………….…………………………….………...103 v LIST OF FIGURES Figure 1.1.
