Over the next decades, China will face various thorny issues caused by the fasturbanization progress. Therefore, Caofeidian eco-city, being the most prominenteco-city project in China, is currently in the course of planning and construction,thereby providing a sound model for future urban development. The master plan of 30square kilometers area and current situation is fully analyzed by the PEBOSCAinterdisciplinary framework based on the UN Habitat agenda. To better realize theeco-city in a Chinese context, a series of interdisciplinary problems and potentialchallenges of Caofeidian eco-city are identified and corresponding interdisciplinarysolutions are presented in this paper. Deferring to the different city developmentstages, a tentative schedule and back casting goals are set to assess the Ecocityperformance in the next 50 years.

Hållbar utveckling har sedan 1987 definierats enligt Brundtlandrapporten "Vår gemensamma framtid" som en utveckling där dagens generations behov tillfredsställs utan att äventyra framtida generationers möjlighet att tillfredsställa sina behov. Mångtydigheten i begreppet hållbar utveckling har däremot skapat en diskussion i samhället om vad som ska ingå i tolkningen av begreppet och år 1992 i Rio de Janeiro hölls en konferens där man arbetade fram ett program för en hållbar samhällsutveckling, Agenda 21, ett handlingsprogram för det 21:a århundradet. Diskussionen om hållbar utveckling är idag ett inarbetat begrepp i samhällsutvecklingen och något som städerna i allt högre grad försöker anpassa sig efter. Det finns ett kunskapsläge som beskriver vad som ska ingå i den hållbara staden, hur man på bästa sätt planerar med hållbarhet i fokus och vilka modeller som ska användas för att integrera hållbarhetens tre delar ekonomisk, ekologisk och social hållbarhet. Däremot finns det ett glapp mellan teoretiska ramverk och faktisk planering, där många stadsbyggnadsprojekt trots sina hållbarhetsmål inte lyckas att fullt ut bli hållbara i slutändan. Uppsatsens huvudsakliga syfte är att dra en slutsats om det arbete som idag görs för att planera hållbara städer är tillräckligt utifrån den valda planeringsmodellen, SymbioCity, som har sina rötter i det svenska projektet Hammarby Sjöstad, som i olika avseenden används i kinesisk stadsplanering. Genom att jämföra planeringen av Hammarby Sjöstad med Tangshan Bay Eco-city i Kina har vi som mål att avgöra om man utifrån liknande mål och metoder kan planera hållbart där både ekologisk, ekonomisk och social hållbarhet får ta plats. Med utgångspunkt i en teoretisk analysram, som utarbetades efter kriterier och principer om hållbart stadsbyggande, genomförs en kvalitativ textanalys som jämför det svenska byggprojektet Hammarby Sjöstad med Tangshan Bay Eco-city i Kina för att urskilja likheter och skillnader i hur man strävar efter att bygga hållbart utifrån liknande planeringsmodeller. Analysen genomförs i två nivåer där första nivån analyserar SymbioCity som planeringsmodell och i vilka avseenden modellen kan vara ett verktyg för hållbar stadsplanering och i den andra nivån går analysen djupare och mer kritiskt in på hur Hammarby Sjöstad, Tangshan Bay Eco-city och SymbioCity förhåller sig till uppsatsens fyra kriterier för hållbar stadsplanering. Stadsdelarna är konstruerade med liknande mål om hållbarhet men den politiska skillnaden i Kina och Sverige ger olika förutsättningar för medborgardialog och social hållbarhet. Trots den sociala och politiska skillnaden mellan länderna blir arbetets slutsats att en modell trots allt kan vara en grund för planeringen av hållbara städer, men det måste visas hänsyn i arbetet till att en modell som SymbioCity ensam inte täcker in den sociala hållbarheten, vilket behövs för att långsiktigt kunna planera för hållbara städer och samhällen.

Electricity is used all over the world as a basic source of energy, essential for lighting, powering basic appliances and tools, as well as many other technologies important for today's societies. Electricity is produced, transmitted and distributed to consumers with a range of resources and technologies, resulting in a process that has impacts on sustainability. This thesis examines the interconnections among production, regulation and consumption of electricity, investigating the sustainability of the electricity system broadly defined. Under auspices of the Ecoplan China project, a case study approach is used to assess the sustainability of the electricity system in Dalian, China. Gibson (2002a) argues that sustainability ought to be conceptualized as a set of requirements, which are outlined as principles of sustainability. These principles, in this thesis, form the basis for a Sustainability Assessment of the electricity system in Dalian. The principles provide the analytical framework for reviewing the literature that discusses electricity in sustainability terms and in relation to China. Gibson's conception of sustainability is broad and does not provide guidance on specific procedures for conducting a Sustainability Assessment. The sustainability principles operate on complex systems theory and on the principle of integration, resulting in limitations for their practical application. More specifically, Gibson's principles are operationalized with electricity assessment indices derived for use in the study of Dalian. Relevant indicators are selected based on these indices. This work is exploratory in nature, as it tests the utility of the sustainability principles for assessment and indicator developent. The electricity infrastructure and system regulations relevant for Dalian were reviewed, while local consumer attitudes in relation to electricity were also examined. Dalian is dependent on coal as the primary source of electricity. Production infrastructure also includes a limited supply of wind power. A nuclear plant is being constructed in the region to reduce the need for future expansion of coal-based electricity production. The local grid infrastructure has been improved in recent years to increase efficiency of electricity transmission and to ensure that all residents have access to a reliable supply of electricity. Industrial growth and restructuring has increased the demand for electricity. The local regulatory environment is based on a centralized structure, with much input coming from provincial and state government bodies. Local consumer attitudes were investigated with a survey, in order to shed light on how sustainability and electricity are manifested in Dalian residents. This information is qualified in sustainability terms and relevant indicators are derived. The research is intended to start discussion in Dalian for developing a framework for evaluating sustainability of the electricity system and on sustainable development in general. The study supports Dalian's goal for becoming an eco-city and the results provide recommendations for further study of Dalian's electricity system. Dalian has taken steps to improve the electricity system, but a clear strategy to develop long-term sustainability is necessary. In coordination with local experts and government representatives, Ecoplan China is in a good position to further extend research for developing sustainability-based policy and planning tools for Dalian.

In recent years, eco–city as a sustainable urban model has gained increasing prevalence and evolved into a hegemonic urban discourse. As a future vision of urban transformation, eco–city is being increasingly translated into concrete projects, strategies, and policies, mainstreaming urban sustainability and being replicated and proliferated across the world. This study aims to examine, by means of a discursive analytical approach, the construction of eco–city in the Swedish urban context – urban planning and development – with a particular emphasis on definitional and thematic issues, cultural bias, selectivity, framing, and political action. I use six analytical devices to guide the analysis of four documents as an empirical material. Findings show that the construction of eco–city in the Swedish urban context entails aspects of other sustainable urban models: smart city, sustainable city, green city, and compact city, making eco–city as an umbrella metaphor for such models. Also, only combining all projects, it is clear that eco–city has evolved into a comprehensive vision, embracing most of the requirements and norms set for a city to be ecological. While the concept of eco–city tends to incorporate social and cultural dimensions of urban sustainability, the prime focus remains on economic and environmental aspects – in other words, social considerations are marginal compared to economic and environmental ones. Moreover, the discourse of eco–city draws on and is informed by an array of established discourses. Building on previous discursive constructions of reality, it changes urban reality – aspects of its economic and environmental dimensions, by generating new ways of thinking about urban practices through new amalgamations of established discourses. The technological orientation of eco–city has links to urban–economic–political processes of regulation as well as involves selective framing in terms of discursive interpretation of urban–environmental crises as material processes, recontextualization of urban- economic imaginaries, reference to particular meta–discourses, and privileging of particular discursive chains. Technologically-oriented eco–city can be conceptualized as a specific urban practice which is contingent upon hegemonic discourses on the economic, technological and environmental regulation in relation to urbanization and on the agency of various actors advocating energy efficiency and green technologies and forming alliances on sustainable urban issues. Furthermore, the discourse of eco–city is exclusionary, in that it leaves out some topics and facts relating to the negative direct and indirect environmental effects of the so–called green and energy efficiency technologies. In addition, the discourse of eco–city is shaped by cultural frames associated with environmental and climate awareness and the role of technology in enabling and catalyzing sustainable urban transformation. Finally, using different mechanisms, political action has a great impact on the discourse of eco–city in relation with the environment, climate change, and shifts to low–carbon/low-energy cities. It plays a role in the expansion and success of eco–city.

This thesis explores the nexus between 'urban expressionism' and the potentiality of 'Asian urbanism(s)' by exploring ways that different planning paradigms have been located/dislocated in the case of New Songdo City, South Korea. By investigating four expressions of New Songdo City - as an 'Eco-City', a 'Smart City', an 'International City', and as the 'City of the Future' - this thesis argues that urban expressionism can make important contributions to the aims of Asian urbanism(s). Ultimately, this research demonstrates the ways that urban expressionism can be used to destabilize hegemonic Western-centric urban knowledge and city-building practices, and further point to new geographies of theory from which important contributions to urban research can be made. Urban expressions are made evident by various entwined urban rhetorics and worlding practices that operationalize multiple mediums of communication. Consequently, New Songdo City is, first and foremost, a city of simultaneity. To investigate this simultaneity, this research utilizes an exploratory case study approach and multiple qualitative methods that include semi-structured interviewing, focus groups, and surveys to gather insights from residents of Songdo, local experts, public and private sector actors, and other key stakeholder groups. Visual analysis is also used to explore mixed-mediums of data, including promotional videos, images, exhibition displays, magazines, and advertisements. The methods used to undertake this thesis provide a glimpse in to the development of New Songdo City and capture different urban expressions that are articulated by the city through various examples of urban rhetoric and worlding practices. The urban expressions presented in the New Songdo City case are analysed through the lens of Asian urbanism(s) and investigate the ways that hegemonic Western and Euro-centric conceptualizations of 'the urban' and 'the city' have been deployed, articulated, experienced, challenged, and complicated. By extension, this thesis also contributes to a more nuanced conceptualization of Asian urbanism(s) as well as the relevance of New Songdo City for urban theory in South Korean, Asian, and more generalizable contexts.

Wuxi Sino-Swedish Eco-City, a pilot city region with an area of 2.4 km2, is a demonstration project for innovation in energy technology and integrated smart city solutions in China. After the 1st phase of the project, general outlines of the city’s energy system were drawn and applicable technologies are provided. However, no work has been performed on building electricity load projection and load analysis. This thesis will therefore firstly focus on establishing the building electricity load projection model, using simulation software STELLA. Then the model is scaled up for the whole city region. The simulation results show that there is foreseen to be electricity peak in summer and winter, due to the cooling and heating demand. Based on simulation results, an electricity DSM (demand side management) strategy should be implemented in order to balance the load. Peak load shifting strategy is thus chosen to be investigated. Two technology options (ice-storage system and thermal storage system), which could be implemented to balance the electricity peak, is analyzed by scenarios. Also, commercial feasibility of implementing such technologies is discussed. / Wuxi Taihu Sino-Swedish Eco-City

生態都市以永續概念為基礎，強調自我調節與最小能源消耗，使人類與動植物能與自然環境永遠共存。過去於都市計畫領域中，土地使用分區管制工具及都市設計元素，對於生態都市環境之影響似乎尚未完全釐清。此外從環境使用者（包含人類與動植物）面向探討生態都市規劃時，不同環境使用者取向為主之綠色空間規劃相異，又各種綠色空間規劃之適用標的為何過去鮮少提及。為釐清上述研究缺口，本研究之研究目的為建立不同生態都市使用者之生態都市規劃原則，並判別促進生態都市的重要土地使用工具與設計元素，以提供生態都市規劃上之政策建議。 在研究方法方面，首先以ArcGIS建立一模擬都市，並設計出各種規劃元素及其變化情境；接著在模擬都市中模擬所有情境之市綠色空間配置；最後計算個情境之生態指標，並運用彈性系數分析各規劃元素改變對於生態都市改善程度差異。研究結果認為若都市已高度開發、無殘存原始棲地時，規劃應偏向提供人類良好足夠之綠色空間、提升植物生長空間，已達到降低汙染並提升環境品質之生態目標；若生態都市內具部分原始棲地時，綠色空間規劃則可增加綠色網路品質，以提供動物更具生態性之環境。又在所有土地使用工具與設計元素中，縮減式退縮、偏低的建蔽率、鄰棟距離容積向上移轉、前後院距離容積向上移轉為較佳之規劃元素；高度比、街角退縮等元素整體表現普通；此外ㄨ字型建物及十字型建物之退縮對於環境改善程度最大。 / Eco-city is based on the concept of sustainability, emphasizing self-regulation and of energy consumption minimization. In urban planning, the relationship of zoning and urban design elements with eco-city built environment is not totally clarified. Besides, the planning strategy of green space will be different because of different participators living in the city. The city includes people (which can be divided into residents and pedestrians), animals and plants. It’s rarely discussed how green space strategies apply to different types of city in the past. To clarify them, two purposes on this study are established. One is to set up eco-city planning principles which designed for different environment users. The other is to find out good land use tools and urban design elements which can make built environment more ecological. The research methods of this study can be done by the following ways . First, use ArcGIS to establish a simulated urban environment. Secondly, integrate all land use tools and design elements as input, and then simulate each input’s green space configuration. Finally, calculate eco-city index and then analyze with elasticity to evaluate the efficiency of land use tools and design elements for improving environmental quality. The result of study suggests that, if highly developed city lacks habitats, the planning strategy should emphasize on offering sufficient and high quality of greenspace in order to satisfy residents’ leisure needs and plants’ growth spaces. By this way, the goal of pollution-reducing and environment-quality-improving could be reached. If the habitat exists in the city, planning strategy should tend to increase the quality of green network system in order to provide a more ecological environment for animals. Simultaneously, the study finding that among all the inputs, SBU, lower BCR, SDU, and RDU are better for eco-city planning. Besides, HDB, HDR, and HDFAR perform ordinarily. Moreover, TP7 is the most efficient input for improving environment quality, followed by TP6.

近二十年來，環境低碳永續思潮可謂國際城市規劃顯學，各國在城鄉及建築規劃領域之設計思維及技術手法也積極提升，日益精進。台灣政府也不自外於此風潮，施政走向積極回應此地球公民責任，將節能減碳、綠色永續列為政府規劃標案之關鍵議題。工程顧問業面對此項國際競爭挑戰，應透過設計思考程序來養成工程師永續思維，建立解析環境永續低碳議題之整合規劃能力，為本研究之主要研究動機與目的。 本研究爰引歐盟生態城市規劃流程為基礎，導入設計思考理念與手法，建立一套具備全球生態城市規劃思潮、可科學化具體操作雙重特點之整合規劃作業程序。同時，透過平潭總體規劃國際競圖案之實際操練，讓設計團隊體驗在嚴謹的論證前提框架內，藉由科學程序引導，激發出創新提案，也讓設計者體認到整合規劃之必須與重要度。 建置永續城市規劃整合模型亦為本研究之重要成果，主要功能係可檢核運算規劃方案對生態永續層面之達成率。此整合模型以歐盟生態城市規劃流程為主要框架，再納入國內生態社區評估系統之分項指標，兼俱國際前瞻思潮、與國內既有評估系統儘量相容兩項特性。另為因應不同規模尺度規劃任務之精細度要求，將整合模型區分成快速評估及詳實評估兩種版本，並以江蘇啟東濱江新城總體規劃案進行快速評估版之實證演算。 本研究將設計思考導入城市規劃實質作業，誠屬首創，研究成果所建立之整合規劃作業程序與永續城市規劃整合模型，亦屬城市規劃在製程(Process)與供應(Offering)兩類項之創新突破。未來，將持續進行相關專業評估指標之細化、模型執行電腦程式化、成果數值轉化等模型優化擴充，俾使成為引導永續規劃之重要專業工具，戮力工程顧問應盡之企業社會責任。 關鍵詞：生態城市規劃流程、設計思考、永續城市規劃 / During the past two decades, the low-carbon-emission and sustainability should be the two most important issues of urban planning, while all the theory and technical approach related to urban planning are enhanced increasingly sophisticated. Taiwan government is also engaged in this trend. For actively responding to the responsibility as an international citizen, energy saving, carbon reduction, and green sustainable development are requested as key issues of government tenders. Facing these international challenges, how engineering consultancy to develop the integrated planning capability through design thinking process to resolve environmental sustainability and low-carbon agenda, is the principal motive and purpose of this research. Based on the EU eco-city planning process, the integrated planning standard process is established through the concept of design thinking and practices. The global eco-city planning concept and scientific specific operation are both characteristics of this comprehensive planning procedure. Besides, through the practical exercises of Ping-tan conceptual master planning international competition, the design team is experienced how an innovation proposal could be created in this rigorous scientific procedure and the synergy of integrated planning. Establishing the sustainable urban planning integrated model is the important result of this research. This model could evaluate the sustainability commitment of each planning alternatives. The model is developed with the main framework of the EU eco-city planning process and detailed indicators of EEWH-EC model. Taking into account the international forward-looking thought and compatible with the local EEWH-EC model are two significant characteristic of this integrated model. This integrated model is functionally developed into two versions, rapid assessment and detailed assessment, to cope with the different scale of planning tasks. In addition, the rapid assessment version is implemented for the Qi-Dong Riverside new district conceptual master planning project. In this research, the design thinking initiated into urban planning process is a pioneering undertaking. The two findings of this research, integrated planning standard process and sustainable urban planning integrated model, are having innovation breakthrough each other in process and offering of urban planning. The further expansion of the model, Including professional assessment indicators refinement, computer programming implementation, and the output solution formation, will be continued. In the future, the model is expected to be optimized as an important tool for urban planning. It will be the best practice of corporate social responsibility for engineering consultancy.
