| Abstract: | Like other developed countries in the world, the importance of urban renewal in improving the physical environment conditions and the living standards of the public is recognized in Hong Kong. However, many previous studies revealed that a lot of urban renewal projects failed to tackle the problems of urban decay and to satisfy affected parties, and brought the dilemmas and conflicts among the three domains: economy, environment and society. To address the deficiencies of current practices and ascertain the quality of the renewal projects, defining what constitutes a sustainable urban renewal project and how to implement it are crucial issues that have attracted considerable attention in academia and construction industry. In view of this, this study is initiated. The objectives of this research are to develop a sustainable approach in planning urban renewal projects to be conducted in Hong Kong by means of urban design; to identify the relationship between urban design considerations and the sustainable development objectives; to determine the underlying factors that contribute to sustainable urban regeneration and to derive a model for assessing the sustainability level of local urban renewal projects. Through comprehensive literature review, the urban renewal practices and their associated problems were clearly identified. Sustainability concept, value of urban design, design considerations enhancing triple sustainable development objectives, and their interrelationship were also explained. By adopting questionnaire surveys and various statistical analyses such as Independent T-test and Exploratory Factor Analysis, general views of the key stakeholders in Hong Kong on the significance of each design consideration for sustainable development, and the underlying factors that account for the variances in their perceptions could be found. Based on the factors highlighted, the assessment design criteria of the model were identified and its framework was also derived. This framework served as a hierarchy for conducting Analytic Hierarchy Process, which was used to find out the relative importance of individual design criteria and form the skeleton of the assessment model. In order to ensure that the model derived can effectively assess the sustainability level of local urban renewal projects, a valid assessment tool has to be made. Both qualitative and quantitative indicators were developed under various design aspects for benchmarking the project performance systemically. With the help of the experts from the industry and academia, the indicators have undergone a detailed evaluation process, which have revealed that the model composed of 34 indicators was a reliable and valuable tool to achieve the goal of producing sustainable urban renewal projects in Hong Kong. Critical factors meeting the sustainable development objectives and the assessment model are two major outputs of this study. The research findings help to strengthen the understanding of local developers, urban designers and government officials on how to plan a sustainable urban renewal project to create a sustainable community afterwards. They should take into account of those crucial factors extracted from an analysis of the sample opinions from relevant parties in order to attain excellent performance in local projects in the future. Furthermore, the assessment model suggested here can ascertain that local urban renewal projects carried out in the future can deal with the urban problems and benefit the community in various aspects effectively and efficiently because the impacts of the projects on economy, environment and society can be predicted in advance and necessary adjustment to the renewal proposals can also be made. Apart from its practical applications, this research is also useful in academia. Although there is abundant research studying the concept of sustainability and the value of urban design respectively, there are few attempts to combine them into urban redevelopment literature. There are a number of schemes and indicators available for assessing sustainable development, but they are not tailor-made for measuring the performance of urban renewal projects. Therefore, the findings of this research can enrich the contents of related topics. |
