台北市自民國72年起，公佈實施土地使用分區管制規則以來，至今已十幾年，但對於住宅區之環境品質並無明顯改善，反而突顯實施土地使用分區之分組及允許使用組別的問題，究其原因，是法規制定太偏於混合使用及允許使用組別太多。尤其附條件允許組別更為嚴重，幾乎與商業區差不多，而其中產生一些行業別與住宅不相容的情形。 有鑑於此，本研究乃期望透過混合使用相關研究回顧遴選出適當之評估指標項目，再收集專家學者對評估指標之意見，進行修正所遴選之評估指標，作為混合使用環境品質之評估基礎。在其中發現混合使用評估指標相對權重以「守望相助與警衛」權重最大、其次是「購物方便性」、第三為「餐飲方便性」。而「垃圾收集」與「污水排放問題」之小指標相對權重較小。由此不難理解，在專家的觀念裡混合使用之居住環境需以居住安全性之「守望相助與警衛」為第一考量，然後才能考慮混合使用生活之便利性。 由以上所建構之評估指標，經收集居民的意見與專家之賦予權重之後，經整理計算後，所得到評估指數正負得知，混合使用環境品質評估指標中以「寧便居住環境」、「公共安全」之指數呈現正值，而「環境污染公害」為負值，將其大指標之指數加總，發現總值為正數，得知混合使用之居住環境可能是好處多於壞處。 得知評估指標之指數大小之後，筆者再建立相容性行業別操作方式，進行計算行業別之評估指數大小，並建立數學模式，發現行業別之指數總和越大，代表居民與專家愈能接受該行業。負面值越大表示排斥性越大。同時可理解相容性越高之行業對環境影響越少，且對生活機能幫助越大。進而可透過行業別之排序，依混合使用環境品質需求，再訂定不同混合標準，以塑造不同等級之居住環境。 另在新、舊地區之實證過程中得知；混合使用的行業會因道路寬度、區位而有不同混合比例，其中立體混合也與平面混合成正相關。而從實際新、舊地區之業種調查發現，在大安區之業種是屬於都市型，而在萬華區之業種是屬於鄰里型。 綜合言之；本研究透過相關理論回顧與分析，所建立住宅區土地混合使用之評估指標，作為相容性之行業別判斷依據。在其中發現行業別之相容性，可依本研究所擬之評估指標判斷業別對居住環境的影響情形，同時可透指數分析再訂定業種相容性標準，而進行衡量評估指標與行業別之相關性計算。尤其在行業別設立時，將可能對住宅使用產生正面或負面影響情形，以指標的方式表達；如行業別是否產生噪音振動、垃圾處理方式、停車問題、空氣污染..等等問題，儘可能再設有評估標準。待相容性行業別執行一段時間後，依執行情形來修正評估標準，以利後續土地混合使用業種相容性之參考。 / Since the announcement and execution of the Zoning Act of Taipei Metropolitan in 1983, there is no obvious improvement on the living quality in the residential areas. Conversely, there are some issues on the usage classification and permitted usage categories. After further research, it’s found that the Zoning Act biased on the mixed-use, which permitted too much usage in one category. The most serious one was the permitted usage in its appendix, which made the usage of residential area almost the same as the commercial area. After researching on the related documents on mixed-use, the study emerged the appropriate evaluation indicators. Then collecting the experts’ comments, the study modified evaluation indicators accordingly, which formed the bases of environmental evaluation of mixed-use. In between, the relative importance of top three indicators was ranked as “residents’ mutual help and guard”, “shopping convenience” and “dinning convenience”. Both “trash collection” and “waste water manipulation” were less concerned. It understandable that in experts’ concepts, the residential safety was the first consideration then the living convenience. Based on the above evaluation indicators and collected comments from the residents and experts, the study came out the positive and negative values of evaluation indicators. The “quiescence and convenience of living environment” and “public safety” were positive value but “environmental pollution” was negative value. Summing up the big indicators, the value was positive which meant people possibly evaluated highly on the mixed-use in the residential environment. Understanding the importance of indicators, the study rebuilt the operation model for compatible businesses, which calculated the values of business evaluation indicators and built mathematical model. Then the study found out that the greater positive values of summed up indicators, the more representative residents and experts accepted the business. The greater the negative value, the more exclusivity represented. More compatible businesses would less impact the environment but enhance the living functionality. Ranking the business sequences according to the needs of environmental quality in mixed-use, we could build up different grades of living environments by setting up different mixed-use standards. It was proven from the study on the new and old residential areas that the mixed-use ratio of businesses would be differed by the width of road and location in which vertical and horizontal mixed-use are positively related. From the field study, the businesses in Ta-An district belonged to the metropolitan type but those in Wan-Hua district belonged to the tithing type. In summary, the study went through the review and analysis of related thesis then built the evaluation indicators for mixed-use in residential area, which in turn were the bases to identify the businesses compatibility. Utilizing the evaluation indicators, we could identify the business compatibility and its impact on the living environment. Simultaneously, through indicator analysis, new business compatibility could be redefined and evaluate the relationship between evaluation indicators and business relativity. Especially for the business category, which would heavily impact the environment, the indicators could be identified as, e.g., voice and vibration pollution, trash manipulation, parking issue, air pollution...which needed more evaluation standards. After some time of execution, the results could be used to modify the evaluation standard, which would be the reference for the succeeding study of land mixed-use.

Master of Regional and Community Planning / Department of Landscape Architecture/Regional and Community Planning / Jae Hong-Kim / The concept of Live-Work-Play has grown in popularity in the field of planning, as various strands of the planning literature increasingly have highlighted the potential benefits of providing places to live, work, and play in close proximity. This study explores the theoretical foundations of the Live-Work-Play concept and discusses its effectiveness as a strategy for creating vibrant urban areas by reforming the spatial arrangement of the built environments. More specifically, the present study empirically examines how the segregation or the mixture of places to live, work, and play may create differences in terms of growth, inequality, education, the built environment, and transportation by analyzing the Boston metropolitan region as an example. The empirical analysis with the use of census tract level socio-economic data shows that the Live-Work-Play mixes can encourage more desirable travel patterns, while the mixes may not significantly promote growth in small areas. However, the analysis also revealed racial and income inequalities exist in the provision of the mixes in the Boston region. These findings suggest planners carefully should consider the equity issues when adopting the Live-Work-Play concept and providing its potential benefits.

La construction d'immeubles de grande hauteur reste, malgré les débats qu'elle génère, un projet d'actualité dans de nombreuses villes en France. Fort des expériences passées, nombreux sont les projets se tournant aujourd'hui vers le concept de ville verticale. Ces tours multifonctionnelles, mieux ancrées territorialement et ouvertes au public ont alors pour objectif de mieux s'intégrer dans la ville et de permettre une forme d'urbanité. La mise en œuvre de la mixité à l'échelle du bâtiment, la grande hauteur, ainsi que la recherche de qualité urbaine génèrent de nouvelles contraintes techniques, socio-institutionnelles et territoriales peu étudiées à ce jour. En particulier, la complexification des montages de projet, l'enjeu territorial élargi ainsi que le statut particulier des espaces ouverts au public de la tour provoquent de nouveaux questionnements et enjeux public-privé à la fois spatiaux et organisationnels. Dans ce contexte, comment les tours peuvent-elles contribuer à l'urbanité de la ville contemporaine ? En s'appuyant sur une étude comparative de trois projets de tours mixtes franciliens (Phare, Triangle et Duo), ainsi que sur un état de l'art sur la grande hauteur et le concept d'urbanité, nous proposons une typologie des tours au regard de leur contribution à la ville. En développant une approche dynamique de la dimension urbaine des projets de tours au cours de leur fabrication, nous proposons ensuite un outil d'analyse des «trajectoires de projet» dans le temps. Une corrélation apparaît finalement entre ces trajectoires urbaines et les étapes de leur fabrique, et permet une montée en généralité sur les processus de production des différents idéaux-types de tours et de leur urbanité / Despite a controversial scientific and societal debate, building skyward is experiencing a new rise in French cities. This is reflected in the emergence of new high-rise forms: mixed-use towers and even “vertical cities“. Both are usually conceived as more accessible to the public, more linked to the ground, and more “urban». The implementation of mixed-use, height and urban quality in skyscrapers generates a system of specific technical, social and territorial constraints which are little studied so far. New public-private issues concerning both spatial and organisational considerations are caused by the very complexity of the project, the significant impact of the building on its surroundings, as well as the special status of its privately-owned spaces that are open to the public. In this context how can high-rises be produced and contribute to the urbanity of contemporary cities ? First based on a comparative study of three mixed-use tower projects within the Paris region (Phare, Triangle and Duo), then on a literature review of high-rise buildings and the concept of urbanity, we establish a typology of “urban towers“. These are classified according to their relation and their impact on the city. By developing a new dynamic approach of the urban issue of tower projects during their fabrication, we create an analytical tool which can identify temporal “project trajectories“.Finally, we find a correlation between these project trajectories and the stages of their implementation. This allows us to analyse the production process of each class of tower and their urbanity

Understanding the nature of private-public interaction within a development process provides crucial insight into the workings of a new development from the initial vision all the way to post-construction property management. The private and public sectors must work together as partners in the development process, understanding the goals of one another while remaining flexible in their own decision making in order to create a development that best meets the vision of both parties. By studying Cedar Park Town Center and Midtown Commons, located in Cedar Park, Texas and Austin, Texas, respectively, we can grow a greater understanding of how the private-public interaction involved in these cases affected two pioneering mixed-use projects in Central Texas. Utilizing personal interviews as well as documentation from both public and private sources, detailed information was gathered regarding the process and interaction used by private and public parties in both developments. / text

The single family neighbourhood is a favoured residential form, yet this low density residential option is unsustainable. With its high consumption of land and services, the continued development of the traditional single family neighbourhood results in urban sprawl and inefficient use of infrastructure. In addition, zoning regulations that prescribe large lot sizes, deep setbacks and singleuses, create disconnected, mono-functional residential enclaves. Residential intensification is increasingly touted by urban theorists and proponents of sustainable development as part of the solution. This involves focussing new development on underutilized land, which in turn necessitates the acceptance of new housing forms within existing neighbourhoods. However, people are often wary of higher densities and alternative housing options, believing that the qualities of livability that they identify with the single family neighbourhood are threatened. Focussing on ground-oriented residential alternatives, this project examines the key elements that comprise the residential environment and their connection to aspects of livability. A set of guidelines based on principles of sustainable development directs the design for a higher density, environmentally responsive, groundoriented residential development on an infill lot in an existing single family neighbourhood. The final design proposes the division of the single site into five developable lots, introduces four different dwelling types, and integrates into the landscape a stormwater management system. The plan is compared to other similar alternative developments.

This project attempts to break down categorization and systems of thought based on opposing qualities. Instead, disparate elements are considered to work together to increase their individual properties by creating a new property - a condition comprised of the individual elments yet also surpassing them. The word "hybrid" is appropriated to describe the nature of this investigation - the renovation of a turn-of-the-century warehouse building into a multi-use building. The project attempts to describe how a building that contains a range of disparate programmatic elements can go beyond each element's exclusivity to produce a condition in which the resultant is greater than the sum of the individual parts. The project looks at breaking down specific delimitors of adjacent programmatic elements and promotes cross-fertilization between them with the intended result of blurring the seams that separate one from the other. The intent is to investigate, through a series of minimal moves dictated by the conditions of the site and program, whether a condition of richer and more varied experience can be achieved and, as a result, provide a start for defining a condition of architectural hybridity. Due to the size of the building that is investigated, this project focuses on two areas of the building, the insertion of a courtyard and the insertion of a fissure, or crack. The point of these investigations is to provide a tactical solution for the specificities of this particular site while at the same time implying a larger, global strategy that not only infers the remainder of this building but includes similar building types in other locations.

Big-box Urban Mixed-use Developments (BUMDs) are mixed-use developments with a consistent typology that incorporate big-box retailers in a central role. They are also becoming popular in the Atlanta region. While BUMDs serve an important economic role, they also cause issues with stormwater. This study explores integrating a on-site approach to stormwater management into the design of BUMDs. These new designs not only significantly lower the amount of stormwater run-off, but also have potential for better, more attractive, developments.

Economic development brings about urbanisation which may result in rapid housing expansion. The health and well-being of communities is often not considered as a priority of urbanisation with the pressure for developing better economies. Sustainability principles in housing developments are perceived to be able to enhance and to improve the quality of living. The approach to sustainability can, however, be interpreted and prioritised differently. Many developing countries such as Malaysia are depending upon industrialisation for the development of their economies. Continuing urbanisation and industrialisation in these countries indirectly creates tensions between the need for a better built environment, and the push for economic growth. One specific phenomena in Malaysia is the introduction of the mixed-use urban neighbourhood, whereby residential development is netsled within the industrial establishments. On one hand, this helps to create job opportunities and improve the local economy. On the other, it creates concerns in the relations to the house planning, and to the well-being of the residents. These have potential exposures to industrial activities that are associated with environmental problems, such as, poor air quality, local temperature increases, and excessive noise levels. This research applied the current international trends of sustainability practices in housing development in searching for the most appropriate strategies for developing sustainable residential-industrial neighborhoods. Cross reference to other countries strategies and experiences can be adaptation for Malaysian conditions. A residential-industrial community in the city of Pasir Gudang Johor, Malaysia, has been selected as a case study in order to examine the perceived problems of indoor environmental quality in such environments. The result of a questionnaire survey and in-situ measurement indicates that they are facing indoor environmental problems. A set of recommendations for housing guidelines which are tailored for local Malaysians conditions have been identified, and have potential for improving the housing development guidelines and policies for mixed-use community living. Comprehensive strategies will need to be developed to achieve housing development sustainability goals. The development of Master Planned Communities (MPC's) is suggested to be appropriate mechanism to developing planning controls. This will ensure the improvement of indoor environmental quality of living in residential-industrial housing developments in Malaysia. It is anticipated that this research will make a positive contribution to developing decision-making procedures that are appropriate to achieving the goals of sustainable housing development in relation to mixed-used residential housing, It is also expected that this research will assist in establishment of a unified national sustainable housing strategy, and in the rationalised adoption of a master planned community approach.
