Bakgrunden till arbetet är en problematik som bland annat Boverket belyser och som idag är aktuell i flera kommuner, nämligen att kommunerna vill bygga tätare, mer yteffektivt och funktionsblandat. Samtidigt är bostadsbristen fortfarande ett problem i flera kommuner. Studenter och unga vuxna är särskilt drabbade av bostadsbristen och har svårigheter med att skaffa en bostad utifrån deras ekonomiska förutsättningar. Med detta i åtanke är bostäderna i förslaget avsedda för denna målgrupp. Detta arbete har som mål att presentera ett förslag på hur tillfälliga bostäder i form av modulhus kan byggas på underutnyttjade platser i storstäder som Stockholm. En inspiration till arbetet var konceptet SNABBA HUS som handlar om att bygga flyttbara modulhus på tomter med tillfälliga bygglov. Syftet med denna studie är att visa ett exempel på hur estetiskt tilltalande och välutformade modulhus kan bidra till att omvandla en underutnyttjad plats till ett multifunktionellt område. Fokus för arbetet ligger på gestaltning och byggnadsutformning. Med hänsyn till de miljöaspekter som varit av stor vikt under utbildningens gång är frågor kring vatten- och avloppshantering samt hållbara materialval av intresse i arbetet. I arbetet gjordes en lokaliseringsutredning för att identifiera en lämplig plats och kartlägga dess förutsättningar för uppförandet av de framtagna modulhusen. Genom en designundersökning som innefattat granskning av liknande projekt kring modulhus har metoder för en mer estetiskt tilltalande utformning identifierats. Via litteraturstudier och konsultationer undersöktes möjligheten för tillämpning av ett småskaligt vatten- och avloppsystem för att göra bostäderna oberoende av allmänna ledningssystem och främja mobilitet. Litteraturstudier om KL-trä (korslimmat trä) har genomförts för att sammanlänka de miljömässiga och estetiska aspekter som varit viktiga under arbetet. Arbetet har lett till ett förslag på utformningen av studentbostäder uppförda med tillfälligt bygglov ovanför en parkeringsplats. Modulhusen är utformade efter standardmåtten för en parkeringsplats och de gällande kraven för transport. De flyttbara modulhusens konstruktion möjliggör att de kan staplas i höjd- och sidled enligt önskemål. Uppförandet av bostäderna skulle innebära ett bättre utnyttjande av platsen för att möta kommunernas behov och kan antas skapa underlag till framväxt av ett multifunktionellt stadsområde. / The background of this work is an issue that the Swedish National Board of Housing, Building and Planning (Boverket) illuminates and which is currently relevant in several municipalities in Sweden, namely efforts towards a mixing of functions, densification and a more efficient exploitation of urban areas. The housing shortage is still a problem in several municipalities. Students and young adults are particularly affected by the housing shortage and have difficulties obtaining a home due to their financial conditions. The dwellings in the proposal of the study are intended for this target group. The goal of this thesis is to present a proposal on how temporary dwellings in the form of modular houses can be built on underutilized sites in big cities such as Stockholm. An inspiration for the thesis was the concept SNABBA HUS which is about building mobile modular houses with temporary building permits. The purpose of this thesis is to show an example of how well-designed modular houses can contribute to the conversion of an underutilized space into a multifunctional area. This work has focused mainly on design and planning for housing. Questions about water, sewage and sustainable materials have been of interest due to the environmental aspects that have been of significant importance during the education of the authors. A survey was carried out in order to identify a suitable location for the assembling of the proposed module houses. Methods for a more aesthetically pleasing design have been identified through a design study that included examination of similar projects about modular houses. Literature studies and consultations were carried out to examine the possibility of applying a small-scale water and sewage system to make the houses independent of general pipeline systems and promote mobility. Literature studies about CLT (cross-laminated timber) were made in efforts to link the important aspects of environment and design. This thesis presents a proposal of the design of student housing raised above a parking lot with a temporary building permit. The modular houses are designed to fit the standard measures of two parking spaces and to meet the conditions regarding transportation. The way the modules are constructed makes it possible to stack them in close position and on top of each other. The assembling of the houses would mean a higher grade of exploitation to meet the need of the municipalities and can presumably create a basis for the emergence of a multifunctional urban area.

Humans’ activities in urban areas put a strain on local water resources. This paper introduces a method to accurately simulate the stress urban water demand in Germany puts on local resources on a single-building level, and scalable to regional levels without loss of detail. The method integrates building geometry, building physics, census, socio-economy and meteorological information to provide a general approach to assessing water demands that also overcome obstacles on data aggregation and processing imposed by data privacy guidelines. Three German counties were used as validation cases to prove the feasibility of the presented approach: on average, per capita water demand and aggregated water demand deviates by less than 7% from real demand data. Scenarios applied to a case region Ludwigsburg in Germany, which takes the increment of water price, aging of the population and the climate change into account, show that the residential water demand has the change of −2%, +7% and −0.4% respectively. The industrial water demand increases by 46% due to the development of economy indicated by GDP per capita. The rise of precipitation and temperature raise the water demand in non-residential buildings (excluding industry) of 1%.

Dans un contexte de croissance démographique dans lequel certaines ressources naturelles sont de plus en plus limitées, une gestion optimisée et conjointe des réseaux publics de l’eau et de l’électricité s’impose. L’ouverture progressive des marchés de l’électricité à la concurrence et les changements de réglementation dans plusieurs pays ont contribué au développement des mécanismes de la flexibilité de la demande, permettant d’impliquer directement les consommateurs dans la gestion de l’équilibre offre-demande du réseau électrique. Les systèmes d’eau potable, étant de grands consommateurs d’électricité, disposent d’une flexibilité grâce à la présence d’ouvrages de stockage d’eau (bâches et réservoirs) et de pompes à vitesse variable. Cette flexibilité, souvent exploitée uniquement à des fins de sécurisation des demandes en eau, peut être valorisée pour permettre une meilleure gestion de l’équilibre du réseau électrique. L’objectif de cette thèse est l’évaluation des valeurs économiques et écologiques relatives à l’intégration de la flexibilité des systèmes d’eau potable dans la gestion opérationnelle du système électrique français. Une étude de l’architecture des marchés de l’électricité en France est d’abord menée pour identifier les mécanismes de flexibilité de la demande les plus adaptés aux contraintes d’exploitation des systèmes d’eau. Des modèles mathématiques d’optimisation sont ensuite proposés et résolus à travers certaines heuristiques, en intégrant les incertitudes relatives aux consommations d’eau, aux prix des marchés ainsi qu’à la disponibilité des équipements de pompage. Les résultats numériques, discutés en se basant sur trois systèmes d’eau potable réels en France, intègrent les aspects économiques (en considérant les risques associés), opérationnels et écologiques. Des réductions importantes des coûts d’exploitation des systèmes d’eau sont estimées à travers la valorisation de l’énergie non consommée pendant les moments de pointe sur le marché spot de l’électricité. En parallèle, la considération des incertitudes permet de sécuriser l’opération des systèmes d’eau en temps réel, et de maîtriser les risques économiques relatifs à l’équilibrage du réseau électrique. De plus, des réductions importantes des émissions de CO2, estimées à environ 400 tonnes par jour en France, peuvent être réalisées en réduisant les volumes d’électricité issus des sources fossiles. / In a context of demographic growth in which natural resources are more and more limited, optimized management of water and power networks is required. Changes in electricity markets regulation in several countries have recently enabled effective integration of Demand Response mechanisms in power systems, making it possible to involve electricity consumers in the real-time balance of the power system. Through its flexible components (variable-speed pumps, tanks), drinking water systems, which are huge electricity consumers, are suitable candidates for energy-efficient Demand Response mechanisms. However, these systems are often managed independently of power system operation, for both economic and operational reasons. In this thesis, the objective is the evaluation of the economic and the ecological values related to the integration of drinking water systems flexibility into power system operation through french demand response mechanisms. An analysis of the architecture of french electricity markets is first conducted, allowing to target the most suitable demand response mechanisms considering water systems operating constraints. Some mathematical models to optimize water systems flexibility are then proposed and solved through original heuristics, integrating uncertainties about water demands, market prices and pumping stations availability. Numerical results, which are discussed using three real water systems in France, integrate the economic aspects inclunding risks, operational and ecological aspects. Significant reductions in water systems operating costs are estimated through the optimization of demand response power bids on the French spot power market during peak times. In parallel, uncertainties consideration secures the operation of water systems in real time, and makes it possible to manage economic risks related to the power grid balancing. In addition, significant savings in CO2 emissions, estimated to around 400 tons per day in France, can be achieved by reducing electricity production from fossil sources.

Increasing societal demand for automation has led to considerable efforts to control large-scale complex systems, especially in the area of autonomous intelligent control methods. The control system of a large-scale complex system needs to satisfy four system level requirements: robustness, flexibility, reusability, and scalability. Corresponding to the four system level requirements, there arise four major challenges. First, it is difficult to get accurate and complete information. Second, the system may be physically highly distributed. Third, the system evolves very quickly. Fourth, emergent global behaviors of the system can be caused by small disturbances at the component level. The Multi-Agent Based Control (MABC) method as an implementation of distributed intelligent control has been the focus of research since the 1970s, in an effort to solve the above-mentioned problems in controlling large-scale complex systems. However, to the author's best knowledge, all MABC systems for large-scale complex systems with significant uncertainties are problem-specific and thus difficult to extend to other domains or larger systems. This situation is partly due to the control architecture of multiple agents being determined by agent to agent coupling and interaction mechanisms. Therefore, the research objective of this dissertation is to develop a comprehensive, generalized framework for the control system design of general large-scale complex systems with significant uncertainties, with the focus on distributed control architecture design and distributed inference engine design. A Hybrid Multi-Agent Based Control (HyMABC) architecture is proposed by combining hierarchical control architecture and module control architecture with logical replication rings. First, it decomposes a complex system hierarchically; second, it combines the components in the same level as a module, and then designs common interfaces for all of the components in the same module; third, replications are made for critical agents and are organized into logical rings. This architecture maintains clear guidelines for complexity decomposition and also increases the robustness of the whole system. Multiple Sectioned Dynamic Bayesian Networks (MSDBNs) as a distributed dynamic probabilistic inference engine, can be embedded into the control architecture to handle uncertainties of general large-scale complex systems. MSDBNs decomposes a large knowledge-based system into many agents. Each agent holds its partial perspective of a large problem domain by representing its knowledge as a Dynamic Bayesian Network (DBN). Each agent accesses local evidence from its corresponding local sensors and communicates with other agents through finite message passing. If the distributed agents can be organized into a tree structure, satisfying the running intersection property and d-sep set requirements, globally consistent inferences are achievable in a distributed way. By using different frequencies for local DBN agent belief updating and global system belief updating, it balances the communication cost with the global consistency of inferences. In this dissertation, a fully factorized Boyen-Koller (BK) approximation algorithm is used for local DBN agent belief updating, and the static Junction Forest Linkage Tree (JFLT) algorithm is used for global system belief updating. MSDBNs assume a static structure and a stable communication network for the whole system. However, for a real system, sub-Bayesian networks as nodes could be lost, and the communication network could be shut down due to partial damage in the system. Therefore, on-line and automatic MSDBNs structure formation is necessary for making robust state estimations and increasing survivability of the whole system. A Distributed Spanning Tree Optimization (DSTO) algorithm, a Distributed D-Sep Set Satisfaction (DDSSS) algorithm, and a Distributed Running Intersection Satisfaction (DRIS) algorithm are proposed in this dissertation. Combining these three distributed algorithms and a Distributed Belief Propagation (DBP) algorithm in MSDBNs makes state estimations robust to partial damage in the whole system. Combining the distributed control architecture design and the distributed inference engine design leads to a process of control system design for a general large-scale complex system. As applications of the proposed methodology, the control system design of a simplified ship chilled water system and a notional ship chilled water system have been demonstrated step by step. Simulation results not only show that the proposed methodology gives a clear guideline for control system design for general large-scale complex systems with dynamic and uncertain environment, but also indicate that the combination of MSDBNs and HyMABC can provide excellent performance for controlling general large-scale complex systems.

Syftet med det här examensarbetet var att undersöka 3-5 åringars förmåga att utveckla sin förståelse för vattnets väg till kranen genom med en pedagogisk aktivitet. Genom den pedagogiska aktiviteten gavs barnen möjlighet att färdas genom vattensystemet med sina kroppar och sinnen, från sjön till kranen. För att kartlägga hur barnens förståelse utvecklats genomfördes kvalitativa intervjuer före och efter den pedagogiska aktiviteten.Jämförelsen mellan resultaten av förintervjuerna och uppföljningsintervjuerna pekar på en tydlig utveckling av barnens förståelse av vattnets väg till kranen, som ett tekniskt system. Flera av barnen utvecklade sin förståelse för att vårt hushållsvatten måste genomgå en reningsprocess, färdas genom olika komponenter i vattensystemet och rör innan det slutligen når kranen och kan förtäras. / The purpose with this degree thesis was to examine 3-5 year old´s ability to develop their understanding of the path of the water to the tap through an educational activity. Through the educational activity the children was given the opportunity to travel through the water system with their bodies and senses, from the lake to the tap. Qualitative interviews were carried out before and after the educational activity to map out the children´s understanding and how it had developed after the educational activity.The comparison between the results of the pre-interviews and follow-up interviews indicate a clear development of the children´s understanding of the path of water to the tap, as a technical system. Several of the children developed the understanding that our domestic water must undergo a purification process, travel through various components of the water system and pipes before it finally reaches the tap and can be ingested.

Rückläufige Bevölkerungszahlen und Siedlungsflächenwachstum führen zu steigenden Kosten für leitungsgebundene Infrastrukturen. Dies gilt besonders für die Abwasserentsorgung, die in Deutschland überwiegend über die öffentliche Kanalisation erfolgt. Bei Neuerschließung können im Falle geringer Siedlungsdichten dezentrale Abwassersysteme Kostenvorteile gegenüber zentralen Systemen aufweisen. Lassen sich aber durch Dezentralisierung auch Kosten im bereits erschlossenen, von Schrumpfung betroffenen, Siedlungsbestand reduzieren? Um hierauf Antworten zu geben, werden Kosten der Transformation zentraler Abwassersysteme hin zu stärker dezentral angelegten Strukturen berechnet. Am Beispiel eines realen Abwasser-Entsorgungsgebietes wird ein Verfahren entwickelt, das eine Kostenbewertung der schrittweisen Dezentralisierung technischer Abwassersysteme ermöglicht. / Declining populations and an expansion in settlement areas have led to a rise in the cost of pipeline networks for household supply and waste removal. This is particularly true of waste-water removal, which in Germany is primarily managed using public sewage systems. The work at hand tries to give answer to the question, if decentralisation can lower costs in the building stock affected by shrinkage, which is already connected to the waste-water network.
