This study uses complexity theory to examine the space of the street. In a morpho-ecological city, process creates form just as form creates process. The process of movement is a critical form generator within the urban system. In this thesis, the urban system comprising streets/ car/pedestrian is examined. If this collection of urban modes of mobility is a complex system capable of selforganising behaviour, what effect does the ordering imposed by traffic engineering have on this system? I look at the driving body and the walking body as co-creating the city by their movement through urban space. I suggest that, through attention to the fragments of interactions enacted during these movements, we can, through design, allow for the emergence of selforganising behaviour. Urban shared streets, descendants of the ‘woonerf’, appear to function more efficiently than engineered streets, without the usual traffic ordering. The counterintuitive success of these streets implies a self-organising behaviour that is generated by the density of interaction between the inhabitants of the street. These designs potentially work as a change agent, a catalyst, operating within a complex system. This has the potential to move systems from one attractor state to another. A city built with these spaces becomes a city of enfilades; an open system of spaces that are adaptable to uses that fluctuate with time and avoid thickening the palimpsest of traffic engineering. I look at siting shared streets in Wellington, based on jaywalking, a transgressive use of the streetspace that prefigures a shared space, and changes to urban networks associated with such designs. Interaction within the city is a creative force with a structure. City design needs to consider and address this infrastructure and design for it. The infrastructure of interaction has been subsumed by the infrastructure of movement. Shared streets indicate there may not be a need for this – they can be integrated. The process of movement creates instances of interaction; therefore designing spaces of/for movement must be designed to enhance the infrastructure of interaction. The result of such interaction is not just somewhat better; it may be a phase change - catalytically better .

<p>The purpose of this study is to find potential areas suitable for energy production using renewable sources. For this aim, accurate assessments are necessary. The assessments include geographical suitability, closeness of infrastructure and observing local and regional framework concerning the use of renewable sources together with environmental protection.

Depuis quelques années, l’urbanisme tend à considérer de plus en plus la question patrimoniale. Au Québec, c’est suite à l’adoption, en 1980, de la Loi sur l’aménagement et l’urbanisme que fut formellement introduite la donne patrimoniale dans la pratique urbanistique. Bien que cette pratique tente aujourd’hui de poser la conservation du patrimoine bâti comme l’une de ses préoccupations, elle ne parvient pas à l’assumer complètement. En nous basant sur la définition du patrimoine urbain telle que proposée par Gustavo Giovannoni, nous voulons, par cette étude, amorcer une réflexion sur les enjeux d’une approche urbanistique du patrimoine urbain. Nous proposons dans un premier temps un survol de l’évolution de la notion de patrimoine urbain. Cette évolution est mise en relation avec la constitution d’un regard sur le patrimoine bâti québécois. Nous analysons, par la suite, trois moments clés dans la constitution d’un tel regard. La mise en contexte de la naissance de l’urbanisme québécois constitue, quant à elle, le troisième et avant-dernier volet de notre réflexion. À la lumière de cette analyse, nous considérons que le regard de l’urbaniste, posé sur le patrimoine bâti, témoigne encore aujourd’hui d’un désintérêt pour la forme. L’abandon du domaine du physico-spatial au profit d’une gestion rationnelle de la ville a engendré une méconnaissance des processus de constitution des ensembles bâtis et du rôle des formes spécialisées polarisantes. Une véritable approche urbanistique du patrimoine bâti ne saurait passer que par la reconnaissance des processus morphogénétiques des ensembles urbains anciens et de leur inscription dans la ville contemporaine. / For a few decades now, urban planners have tried to include the conservation of built environment in their practices. In Quebec, the first introduction of this consideration takes place in 1980 by the adoption of the Act respecting land use planning and development. Unfortunately, this new consideration was never fully included in the practice, even if urban planning tried to considerer conservation of built environment as one of his main interest. Regarding the definition of built heritage by Gustavo Giovannoni, this study is concerned with the consideration of built heritage in an urban planning’s point of view. In the first part, we will go through an overview of the evolution of the term built heritage. Secondly, we will review three different moments in the constitution of a specific point of view of Quebec’s built heritage. Finally, we will dedicate the third part of our thesis to the birth of urban planning in the province of Quebec. The results of our study show that the modern urban planner’s point of view on built heritage is still characterized by a disinterest in the urban and architectural forms. The focus made by urban planners on the rational management of the twentieth century’s city caused a misunderstanding of its evolution process. What we will demonstrate is that a real urban planning’s point of view on built heritage must consider these processes as well as the inclusion of the old city within the new agglomeration.

Les nombreux exemples réussis où l’aménagement du territoire intègre des milieux naturels nous ont amenée à nous questionner sur les techniques d’intégration des milieux naturels et les outils de planification disponibles au Québec. La présente recherche porte sur le volet environnemental du projet résidentiel le Faubourg de la Pointe-aux-Prairies à Montréal (FPP) situé dans l’Arrondissement Pointe-aux-Trembles/Rivière-des-Prairies/Montréal est. Un premier objectif relié aux résultats nous a permis d’analyser le taux de succès du quartier FPP à intégrer efficacement des préoccupations environnementales concernant la mise en valeur des milieux naturels. En nous basant sur le taux de conservation, l’intégrité écologique et les témoignages des intervenants de la Ville de Montréal, nous avons déterminé que le plan d’aménagement du projet présente un bilan environnemental mitigé. Un second objectif relié aux processus nous a permis de déterminer si les outils sollicités pendant la conception et la mise en œuvre du projet ont facilité l’intégration des milieux naturels. En nous basant sur les outils d’encadrement et proactifs utilisés tout au long de la mise en oeuvre, nous avons déterminé que ceux-ci sont inadaptés à certaines situations. La non intégration des milieux protégés dans les outils de planification, la destruction des milieux aquatiques avec l’accord du Ministère de l’environnement (MDDEP), le manque de vérification des ententes lors de l’attribution des certificats d’autorisation, l'absence de protection des milieux naturels terrestres et la difficulté d’évaluer les bénéfices économiques de l’intégration de la nature ont été les défis majeurs observés. / Studies have revealed that the process of integrating nature to development is painstakingly difficult at best. On the outset, one should question the nature and efficiency of available planning tools and distinguish whether or not they are at the source of this delay. A case study pertaining to conservancy and planning, the residential development Faubourg de la Pointe-aux-Prairies (FPP), located in Montreal, Canada, made possible the exploration of these questions. Our first goal was to determine if FPP had successfully integrated nature into its development. By evaluating nature quotas, ecosystem resiliency and numerous feedbacks from municipal actors, it was determined that the project had not successfully integrated nature into its development. While the project conserved 25% of its surface area, no efforts were undertaken to guarantee the long term viability of the ecosystem present on the site. The second goal evaluated the implementation process of the same case study, by observing the various tools and incentives applied by various public and private stakeholders. It became quite clear that some tools were maladapted to certain specific contexts. Protected areas were seldom included in the municipal planning tools, wetlands were destroyed with the explicit authorization of the ministry of Environment (MDDEP), the MDDEP did not verify the authenticity of deals between third parties when awarding permits and certifications, there was no tools protecting woodlands and other terrestrial ecosystems and finally, the municipality did not analyze the economical benefits of including nature to private developments.

Dans le contexte d’urbanisation fulgurante de l’Asie du sud-est, les zones périurbaines agricoles vietnamiennes subissent des pressions environnementales croissantes et sont loin d’être équipées en infrastructures. L’assainissement présente un important manque d’investissement. La thèse s’est intéressée aux stratégies et aux mécanismes de financement qui aideront à réduire l’écart entre l’offre et la demande d’assainissement. Deux hypothèses principales ont été posées. D’abord, des fonds supplémentaires doivent provenir des ressources nationales, locales et celles des utilisateurs. La seconde hypothèse pose qu’il faudra investir avantage dans des activités qui augmenteront la durabilité des services d’assainissement, comme l’éducation et la promotion, qui en plus favorisent les contributions locales. La thèse a tenté de répondre à la question suivante : Dans le contexte périurbain d’Hanoi, comment mettre à contribution les ressources locales pour améliorer l’accès et la durabilité de l’assainissement? L’étude de cas est un projet communautaire pilote de gestion des eaux usées en banlieue d’Hanoi. Les facteurs de demande pour de l’assainissement et leurs effets sur la durabilité du projet ont été analysés auprès des ménages, des acteurs du village et des acteurs nationaux liés à l’assainissement. La thèse a d’abord permis d’actualiser les connaissances sur deux aspects importants : le cadre institutionnel qui encadre le financement de l’assainissement et les coûts et bénéfices de l’assainissement alternatif au Vietnam. Ces deux sujets présentaient une lacune sérieuse au niveau de la documentation. Puis, malgré de faibles capacités au niveau local, la demande réelle pour de l’assainissement était beaucoup plus importante que celle relevée dans la littérature. La recherche a permis de conclure que les institutions gouvernementales pourraient compter sur une plus grande contribution du milieu local si la planification ciblait ces facteurs : l’éducation et promotion, une grande part de décision et de gestion au niveau local et des technologies plus simples. / In the context of high urbanization in Southeast Asia, peri-urban areas suffer increasing environmental pressures and lack access to funding and environmental infrastructures. The thesis focuses on strategies and financing mechanisms that will help reduce the gap between supply and demand for sanitation. The thesis tries to answer the following question: In the context of suburban Hanoi, how does one draw upon local resources to improve the access to and sustainability of sanitation? The case study is a pilot community wastewater management project in the suburbs of Hanoi. The thesis analyzes the demand for sanitation and its impacts on the sustainability of the project in the home, village and region. Two main hypotheses are set forth. First, national resources and local users should additionally fund sanitation infrastructures. Second, there is a need to invest further in activities that enhance the sustainability of sanitation, like education and promotion, which will in turn encourage local contribution. The thesis updates knowledge in two important areas related to sanitation: the institutional framework, which governs the financing of sanitation, and the costs and benefits of alternative sanitation in Vietnam. At the onset of this research, both subjects lacked any significant literature. Despite weak local capacities, it was discovered that the real demand for sanitation happened to be much greater than that found in previous documentation. The research concludes that government agencies could count on a greater contribution from communities if efforts are directed towards education and promotion, on top of conferring greater responsibilities to local populations, and opting for simpler technologies.

Ce mémoire présente l’étude de cas de la ville de St George, ancienne capitale du protectorat britannique des Bermudes. Sa situation géographique particulière et la présence d’un ensemble architectural colonial britannique et d’ouvrages militaires lui ont récemment valu le titre de Site du patrimoine mondial de l’UNESCO, ce qui constitue une reconnaissance de la valeur exceptionnelle universelle de cet ensemble urbain. Cette inscription survient au moment où les autorités locales souhaitaient diversifier l’économie de l’archipel en misant davantage sur le tourisme culturel et patrimonial. L’hypothèse centrale de ce mémoire est que la ville St George se révèle, au sens où l’entendent G.J. Ashworth et J.E. Tunbridge dans leur ouvrage The tourist-historic city, un « joyau du patrimoine », ce dernier étant défini comme une petite collectivité territoriale recelant des ressources historiques exceptionnelles qui en définissent de manière notable la morphologie urbaine et l’identité paysagère et orientent les politiques municipales. La recherche, suite à la présentation d’un cadre théorique sur le patrimoine mondial et le tourisme patrimonial, a par ailleurs permis de montrer que le concept de « cité historico-touristique » développé par les mêmes auteurs s’applique aux Bermudes à la condition qu’un transfert d’échelle soit opéré. En effet, nous ne sommes pas en présence d’un espace touristique constitué de deux secteurs d’une même ville qui contribuent, chacun à sa façon, à la définition de l’attractivité touristique, mais plutôt de deux petites villes voisines – St-George et Hamilton, la capitale – qui constituent le substrat d’une cité historico-touristique éclatée. / This dissertation presents the case study of the town of St. George, historic capital of Bermuda. Its unique geography, the presence of British colonial architecture and of many military forts allowed its inclusion on the UNESCO world heritage List. This nomination in itself constitutes a recognition of the exceptional universal value of this urban entity. This inscription happens at the exact moment where the local authorities wish to diversify the archipelago’s economy by exploiting cultural and heritage tourism. The hypothesis of this dissertation is that the town of St. George is, according to the proposition of G.J Ashworth and J.E Tunbridge in their book The tourist-historic city, a «heritage gem », that is, a small community containing a great number of exceptional historic resources shaping the urban morphology, the landscape identity and local policies. The research, following the introduction of the relevant theoretical framework on world heritage and heritage tourism, demonstrated that the concept of the “tourist-historic city” developed by the same authors can be easily applied to the case of Bermuda if a scale reduction is made. Indeed, we are not presented with a touristic space created by two different sectors of the same city, but by two small neighbouring cities – St. George and Hamilton, the capital – which are the basis of a fragmented tourist-historic city.

Cette recherche porte sur la mise en oeuvre de stratégies visant à stimuler le développement résidentiel au centre-ville de Montréal depuis la fin des années 1980 . En nous appuyant sur une double étude de cas portant sur le redéveloppement de deux friches périphériques à la vieille ville, le faubourg Québec et le faubourg des Récollets, nous montrons comment les pouvoirs publics locaux peuvent, par le biais de diverses mesures incitatives, faire converger les stratégies d’affaires des promoteurs immobiliers avec les objectifs urbanistiques de l’administration. D’une manière parfois improvisée, les pouvoirs publics montréalais ont ainsi mis en place un système d’opportunités et de contraintes dans le but d’inciter les promoteurs à investir dans les faubourgs. Notre recherche constate que bien que le système mis en place par les pouvoirs publics ait laissée indifférente une majorité de promoteurs, il a néanmoins permis à un petit nombre d’entre eux de se tailler une place sur le marché, ceux-ci pouvant maintenant jouer un rôle actif dans le renouvellement du centre-ville, et ce bien au-delà des limites des faubourgs. / This thesis looks at the design and the implementation of strategies aimed to stimulate the development of residential neighbourhoods in downtown Montreal since the end of the 1980s. Following from a double case study about the redevelopment of two derelict industrial districts next to Old Montreal, the faubourg Quebec and the faubourg des Récollets, we show how local authorities can, by means of a bundle of incentives, encourage the investment of property developers in order to make their business plans converge with the goals of the local planning authorities. In a rather improvised manner, the Montreal government set up a combination of « opportunities » and « constraints » to entice partnerships with the private sector in order to foster the development of the two districts. Our results show that although the system set up by authorities left indifferent a majority of developers, it nevertheless allowed a small number of them to establish themselves in a now very profitable share of the Montreal real estate market.

Le design urbain, dimension de la pratique urbanistique, consiste principalement en la manipulation de la forme urbaine selon une démarche ciblée et encadrée. Les approches sont aussi nombreuses que diversifiées. On peut néanmoins les classer en deux catégories : les approches visant la forme urbaine en tant qu‟objet qui contient l‟organisation formelle de la ville et celles qui visent le travail sur la forme urbaine afin d‟organiser la dynamique urbaine humaine. Les deux types d‟approches soutiennent différentes démarches d‟aménagement qui contribuent à développer la forme urbaine et la dynamique des lieux. Parmi celles-ci se trouve la vision de type empirique, laquelle vise l‟expérience urbaine à l‟échelle du piéton. Les écrits et les théories à ce sujet sont variés et pertinents. La présente recherche porte sur la transposition des prescriptions empiriques dans la planification d‟un projet qui intègre une démarche de design urbain. Au moyen d‟une étude de cas, la Cité multimédia à Montréal, il s‟agit de comprendre plus spécifiquement comment le canevas maître du design urbain, soit l‟espace public, est étudié et reformulé et ce, en accordant une attention particulière pour la dimension empirique du futur aménagement. Quelles sont les balises ou les composantes qui permettent à la dimension empirique de se déployer dans la conception d‟un projet urbain qui vise une reformulation de la forme urbaine? / Urban design, a dimension of urbanistic practice, principaly consists in urban forms manipulations according to a formal and targeted approach. Approaches are numerous and diversified, altought they can be classified in two categories: those who consider the urban form as an object including the city's formal organisation and those who consider the work on the urban form as a way to organise the city's humane dynamics. Both of them support specific planning approaches that contribute to the urban form and location dynamcs developpement. Among these, the empirical type vision targets the pedestrian scale urban experience. Litterature and theories are various and pertinent. The present research concerns transposition of empirical prescriptions in the planning of a project that includes an urban design approach. Threw a case study, Montreal's Cité du Multimédia, the goal is to understand more specificaly how the public space, urban design's master grid, is studied considering the empiric dimension of the developpement. What are the markers or components allowing the empirical dimension to develop in the planning of a project that includes reformulation of the urban form?

Le projet de territoire n’aura jamais suscité autant de débats et de passions. Son devenir mobilise à bien des égards la construction collective d’un dessein se matérialisant par des formes qui informent des forces tout autant que par des forces qui investissent des formes lesquelles traduisent les valeurs du moment. Par conséquent, cette projection dans un avenir partagé amène des exigences sociales en matière d’édification du projet de territoire mettant à l’ordre du jour la complexité d’une telle entreprise. L’enchevêtrement d’actions et de logiques qui s’y opèrent et qui s’y expriment pour en élaborer, dans la plus grande incertitude, les contours d’un futur souhaité nous presse de s’y prononcer : la construction complexe d’un dessein territorial s’exhibant nous interpelle quant à son évaluation voire quant à sa reformulation. Parmi les modalités d’expression qui permettent une telle délibération, il y a l’énoncé visuel. Médiation discursive privilégiée, elle autorise l’élaboration et la mise en scène collective d’un devenir territorial possible. Or depuis quelques années, au couple projet / représentation, vient se superposer une autre médiation, celle du numérique. Portée par le développement des technologies de l’information, celle-ci s’invite dans le champ de l’édification du projet de territoire. En s’alliant avec la puissance de l’image, elle recompose les représentations d’un dessein territorial collectivement formulé, ouvrant un nouvel espace d’actions à l’occasion d’une démarche de planification. Démarche de plus en plus complexe. De surcroit, la présente recherche tient cette complexité non comme un mot «fourre-tout» ou une tare dont il faudrait se débarrasser, mais se résout à l’affronter en s’inscrivant dans un paradigme en pleine gestation, celui de la «pensée complexe». La fécondité autant conceptuelle qu’opératoire d’une telle inscription permettra de jeter un regard renouvelé sur une pratique à travers une de ses modalités discursives à la fois la plus manifeste et la moins questionnée, à savoir l’énoncé visuel. En fin de compte, les représentations notamment celles construites et véhiculées par le numérique sauront-elles rendre compte et relever le défi de l’édification collective d’un projet de territoire qui se pose dans toute sa complexité ? Telle est en substance le questionnement dont cette recherche s’attellera à apporter des éléments de réponse et à esquisser de nouvelles perspectives. / Land Planning has never given rise to so much debate and passion. It involves to a large extent the materialization of a collective design through forms shaped by ideas and ideas shaped by forms, embodying current values. This projection into a shared future carries with it certain social requirements regarding its implementation, rendering the agenda more complex. Multiple actions and positions that are integrated in the planning process in order to devise, within a context of uncertainty, the desired future’s contours push us into quickly prescribing; this entails communication, debate, evaluation and even reformulation The visual statement can be included among those modes of expression allowing such deliberation. As a favoured discursive mediation, it authorizes the development and collective staging of a possible territorial fate. In recent years this project/representation duo has been complemented by another mediation, that of the digital. Buoyed by information technology development, now it falls within the scope of the territorial planning. Magnifying the power of the image, it renews the representation of collective territorial intentions, opening up new possibilities in the planning process, thus making it more complex. Moreover, this research paper considers complexity not as a "catch-all” term or an imperfection to get rid of but confronts it within an upcoming paradigm that of “complex thought.” This approach, conceptually and operationally rich, makes it possible to take a fresh look at land planning through its most visible and least questioned mean of expression, namely visual statements. Ultimately can these representations, especially those constructed and conveyed by digital formats, fully render a complex territorial plan and support the challenge of its collective implementation? These are in essence the issues taken on by this research with the aim of providing at least some answers and opening up new perspectives.
