La gestion des sites et matériaux délaissés (friches, déchets inertes ou organiques) présente de forts impacts sur l’environnement. Leur utilisation en construction de sol (LORVER), pour cultiver de la biomasse non alimentaire (fibres, énergie), peut en réduire le volume et accroître le recours à des ressources renouvelables sans concurrence avec l’agriculture alimentaire ou la protection de la biodiversité. Cette thèse évalue la durabilité de telles filières grâce à l’Analyse de Cycle de Vie. Elle propose des indicateurs complémentaires de ceux couramment utilisés, notamment pour mieux prendre en compte les spécificités des sites délaissés. Elle préconise de prioriser les impacts à l’aune des frontières planétaires (i.e. le niveau d’impact maximal admissible pour ne pas compromettre les écosystèmes), des impacts moyens sur la zone géographique d’implantation des filières étudiées et de leur création de valeur. La grande diversité des matériaux et de leurs débouchés alternatifs, les paramètres les plus importants sont identifiés en combinant des outils d’analyse des incertitudes et d’analyse de données. Il est démontré que les capacités du sol construit à stabiliser durablement les polluants et le carbone sont des composantes essentielles de sa durabilité. Pour les autres impacts (services écosystémiques, qualité de l’air, ressources), la pertinence de LORVER décroît lorsque la distance parcourue par les matériaux pour construire le sol augmente, mais plus encore si d’autres usages de ces matériaux peuvent réduire la demande en commodités dont la production est polluante. Ces résultats donnent les conditions de la durabilité d’une filière de type LORVER / Marginal materials and lands (brownfields, byproducts, inert wastes), the management of which causes significant environmental impacts, can be valorized through soil construction in order to grow nonfood biomass (e.g. fiber, energy). This may reduce their volume and increase use of renewable resources without direct or indirect competition with food crops or biodiversity. This thesis assesses the sustainability of such supply chains with Life Cycle Assessment (LCA), considered one of the most pertinent existing methods. This thesis introduces indicators complementary to current use, in order to improve LCA’s exhaustivity and its taking into account of marginal lands’ specificities. It prioritizes impacts with respect to planetary boundaries (i.e. maximum impacts levels acceptable to avoid ecosystem disruption), average impacts in studied geographic context and added value of the supply chains. Most of these suggestions are applied to the study of a soil construction process using inert and organic wastes (LORVER). The high diversity of materials and alternative management strategies and the most certain tradeoffs and critical parameters are assessed combining uncertainty and multidimensional analysis tools. Constructed soil’s ability to stabilize carbon and pollutants is demonstrated to be its major condition for sustainability. For other impacts (ecosystem services, air quality, resources), LORVER is even less pertinent when the need for material transportation increases, and more importantly if those materials could have otherwise been used to replace commodities polluting to produce. These results highlight when LORVER can be seen as sustainable

Os processos de metropolização e suas extensões na constituição das cidadesregiões globais são vivenciados nas grandes aglomerações urbano-industriais do capitalismo flexível e globalizado da atualidade. Estes processos atuam espacialmente em pelo menos dois sentidos: o primeiro, de ampliação das formas urbano-industriais das metrópoles, muitas vezes extrapolando suas delimitações formais; o segundo, de intensificação das transformações internas das mesmas, e da ressignificação de suas formas e conteúdos. Neste último, as antigas formas da cidade industrial presentes na metrópole consolidada despontam como cemitérios industriais. O estudo dos cemitérios industriais da metrópole de Porto Alegre, apresentado nesta tese, procura analisar a inclusão destas formas espaciais na sua complexidade atual. Partimos do resgate histórico da sua constituição como cidade industrial e seu posterior processo de metropolização, desconcentração e reconcentração que a caracterizam atualmente como uma metrópole de serviços. A seguir, trabalhamos as diferentes abordagens teóricas nos estudos dos cemitérios industriais. A antiga área industrial do Quarto Distrito de Porto Alegre é o estudo de caso apresentado, sendo que sua análise se dá a partir da inserção dos espaços industriais em três lógicas: lógica global, lógica regional e lógica local. Concluímos que os cemitérios industriais, espaços residuais da cidade industrial na metrópole, inserem-se de modo desigual nos diferentes circuitos da acumulação urbana. / The processes of metropolization and its extensions in the formation of global cityregions are experienced in large urban-industrial agglomerations of flexible and globalized capitalism of today. These processes act spatially in at least two directions: first, the expansion of urban-industrial forms of cities, often surpassing their formal boundaries; second, the intensification of internal transformations of the metropolis, and the redefinition of its forms and contents. In this last process, the old forms of the industrial city present in the current consolidated industrial metropolis emerge as "industrial cemeteries" (brownfields). The study of Porto Alegre metropolitan area’s industrial cemeteries, presented in this thesis, analyzes the inclusion of spatial forms in its current complexity. We start from the historic rescue of its formation as a industrial city and its subsequent metropolization, concentration and reconcentration processes, that currently characterizes it as a metropolis of services. Then, we work the different theoretical approaches in studies of industrial cemeteries. The old industrial area of Porto Alegre - Quarto Distrito neighborhood - is the case study on which we concentrate, and the analysis is performed through the integration of industrial space in three logics: global, regional and local logic. We conclude that industrial cemeteries, residual spaces of the industrial city in the metropolis, are unevenly inserted in the different circuits of urban accumulation. / Los procesos de metropolización y sus extensiones en la constitución de las ciudades-regiones globales están presentes en las grandes aglomeraciones urbanoindustriales del capitalismo flexible y globalizado de la actualidad.

The thesis "Economic utilization of industrial structures with focus on railway stations" analyses all possibilities of sustainable use of industrial buildings with a focus on specific example of the Ţiţkov freight station. Based on the general characteristics of both industrial heritage and brownfields are defined steps which are necessary for the protection of valuable locations without present use. The whole process is described in the context of positive and negative externalities. The most important problem is financing the revitalization of problematic objects. The practical part of the thesis describes the previous issues connected to the Ţiţkov freight station including major studies of its potential utilization.

The aim of the assignment was to rehabilitate the area of the Brno embankment of the river Svitava and the nearby surroundings of the river. This is the modification of the river's seashore, the modification of public spaces and the completion of individual objects. The solved territory is defined in the east and north of Cejl streets, on the east of the Svitava river and on the south by Tkalcovska street. The principles of the proposal are based on the necessary changes to the territory. The biggest problem of the area is the area backups for the hypermarket parking lot and the urbanistically incoherent structure of the courtyards and the poorly functioning waterfront. The proposal focuses on making the river accessible and bringing water closer to people. On the waterfront the bicycle path is used not only by cyclists. The former hypermarket is converted into a shopping mall and the ground floor of the seafront is made up of shops, services, cafes and restaurants. For humans, a river was available that could touch water. For relaxation and recreation, the terraces are provided. Better permeability also offers the river itself. By modifying the footbridge and delivering a new footbridge in the middle part, pedicists and cyclists can better cross the river. The park and the reclamation of planted trees have been modified. The Svitavy Drive in the section of the park was also accessible by foot. The siding was preserved to a certain extent in order to be able to prepare a wagon with a café or other possibilities of the Svitava festival under the steam. The construction of new houses increases the attractiveness of the area itself and offers both flats overlooking the river with the dominant of the church as well as services in the workshops of the individual houses. Cejl street has a green and a plumbing and a missing pit. Transparency for people is from the weft loom on the waterfront through the park, business or residential street.Residential homes have ma

The object of this diploma work is the creation of a new built-up area in the location of the former Kohn´s brickfield on the Červený kopec in Brno. This area belongs to of the most considerable brownfields in Brno and nowadays is used mostly as a dumping ground. The concept elaborated in this diploma work has the ambition to offer quality housing possibilities close to the the city centre and to the nature in the same time.

The diploma thesis deals with the evaluation of a public investment project for the regeneration of brownfields. The first part describes the issue of brownfields, causes of their occurrence and reasons for their regeneration from a theoretical point of view. It also defines public project and methods for its evaluation. The second part contains a cost benefit analysis of a public project of Central Polytechnic Workshops. These will be one of several projects within the renovation of the historic Winternitz Mills in Pardubice. The aim of the work is to determine indicators of economic efficiency based on socio-economic flows and assess the feasibility of this project‘s implementation.

This diploma thesis deals with the urban-architectural study of a new residential location on the place of the former area of the artistic-industrial enterprises in Bučovice. It is a brownfields near the Bučovice castle in the historic central zone of the town. The proposal focuses on the urban-architectural solution of the whole area including the conceptual consideration which responds to the possibilities and limits of the development of the industrial complex with a focus on the new building and architectural neoplasm in the historical surroundings.

Architectural and urban design for the reconversion of the part of the Old Brno (former textil fabric of the company Kras and surrounding areas) based on the existing structure of the Old Brno and ideas of compact city (mixing functions> multipurpose buildings, the divergence between private and public space, higher density of the city ...) The work consists of several parts: planning studies, design transportation solutions, waterfront Svratka concept and design for the multifunctional block on the waterfront. What is important is the idea of calming waterfront Svratka (sheltering services to the proposed tunnel and the cancellation of barrier between the city and the river). The waterfront district should become after more attractive location and provide a space for sport, recreation and afternoon walks. There is a block of multipurpose buildings on the waterfront. A corporate underground garage, which is under the block, should be build by a strong investor / city. After underground garage completion, the site will be divided into several parcels and these will be rented to various long-term investors .Tenants can build buildings on them according to their needs. It is possible to build buildings above the garage in sequence development. The project is just one of many options. Individual buildings are design in scale 1:200

The thesis deals with issues of waterfronts along the Svitava in Brno. The project is based on previous two semesters, when a thorough analysis of the waterfront area was elaborated in cooperation with Bc. Linda Pisova and Bc. Zdenka Sedlakova. The analysis deals with issues of brownfields that occupy an extensive area along the river as well. The aim of this work is waterfront revitalization and reinterpretation and creating designs to bring new activities to particular areas that will be adequate to distinctive atmosphere of the sites. Linking the broken relations and propose new ideas as means of recovery or restitution of the city's lost relationship to the river.
