Abstract:
The close layout of buildings is an important cause of urban densification. It makes solar radiation and long-wave radiation being blocked, scattered, and reflected multiple times. Radiant heat is a key factor affecting building energy consumption. The formation mechanism of urban radiation field in the spaces surrounded by dense buildings was analysed. Calculation models were established for the intensity of short-wave and long-wave radiations in spaces surrounded by dense buildings. Characteristics of the radiation field in the enclosed space was analysed. Two typical cities were selected for the analysis of the impact of urban densification on building energy consumption in the hot summer and warm winter zones of China. Studies have shown that the cooling energy consumption of residential buildings in enclosed space can be reduced by 7-15% compared with open space in China's hot summer and warm winter areas. This research will lay the foundation for urban design and architectural design.

Abstract:
With growing populations, economic pressures, and the need for sustainable practices, many urban regions are rapidly densifying developments in the vertical built dimension with mid- and high-rise buildings. The location of these buildings can be projected based on key factors that are attractive to urban planners, developers, and potential buyers. Current research in this area includes various modelling approaches, such as cellular automata and agent-based modelling, but the results are mostly linked to raster grids as the smallest spatial units that operate in two spatial dimensions. Therefore, the objective of this research is to develop a geospatial model that operates on irregular spatial tessellations to model mid- and high-rise buildings in three spatial dimensions (3D). The proposed model is based on the integration of GIS, fuzzy multi-criteria evaluation (MCE), and 3D GIS-based procedural modelling. Part of the City of Surrey, within the Metro Vancouver Region, Canada, has been used to present the simulations of the generated 3D building objects. The proposed 3D modelling approach was developed using ESRI’s CityEngine software and the Computer Generated Architecture (CGA) language.

Abstract:
Urban green spaces reduce elevated urban temperature through evaporative cooling and shading and are thus promoted as nature-based solutions to enhance urban climates. However, in growing cities, the supply of urban green space often conflicts with increasing housing demand. This study investigates the interplay of densification and the availability of green space and its impact on human heat stress in summer. For the case of an open-midrise (local climate zone 5) urban redevelopment site in Munich, eight densification scenarios were elaborated with city planners and evaluated by microscale simulations in ENVI-met. The chosen scenarios consider varying building heights, different types of densification, amount of vegetation and parking space regulations. The preservation of existing trees has the greatest impact on the physical equivalent temperature (PET). Construction of underground car parking results in the removal of the tree population. Loss of all the existing trees due to parking space consumption leads to an average daytime PET increase of 5°C compared to the current situation. If the parking space requirement is halved, the increase in PET can be reduced to 1.3°C–1.7°C in all scenarios. The addition of buildings leads to a higher gain in living space than the addition of floors, but night-time thermal comfort is affected by poor ventilation if fresh air circulation is blocked. The protection of mature trees in urban redevelopment strategies will become more relevant in the changing climate. Alternative mobility strategies could help to reduce trade-offs between densification and urban greening.<p>Urban green spaces reduce outdoor temperatures through evaporative cooling and shading and are thus promoted as nature based solutions to enhance urban climates.

Abstract:
The current main issue in the construction sector in Europe concerns the energy refurbishment and the reactivation of investments in existing buildings. Guidance for enhancing energy efficiency and encouraging member states to create a market for deep renovation is provided by a number of European policies. Innovative methods and strategies are required to attract and involve citizens and main stakeholders to undertake buildings’ renovation processes, which actually account for just 1% of the total building stock. This contribution proposes technical and financial solutions for the promotion of energy efficient, safe, and attractive retrofit interventions based on the creation of volumetric additions combined with renewable energy sources. This paper focuses on the urban reality of Athens as being an important example of a degraded urban center with a heavy heat island, a quite important heating demand, and a strong seismic vulnerability. The design solutions presented here demonstrate that the strategy of additions, because of the consequent increased value of the buildings, could represent an effective densification policy for the renovation of existing urban settings. Hence, the aim is to trigger regulatory and market reforms with the aim to boost the revolution towards nearly zero energy buildings for the existing building stocks.

Abstract:
Urban strategies, representing stories of possible futures, often intervene in already established local communities and therefore call for a considerate urban intervention. This article utilises the ideas of Henri Lefebvre’s socially produced space and of literature on stories involved in planning. Our empirical example tells a story of urban densification aspirations for an inner-city neighbourhood in Tampere, Finland. By combining the interviews of local people and planners with policy documents, we argue that planners’ stories pay too little attention to the place and to local stories. Planners’ abstract visions of the future and local stories building on lived experiences both draw meanings from the same place but have very different intentions. In our case, the consultation of the project started out wrong because the planners neglected a neighbourhood thick in symbolic meanings and the local stories’ power in resistance. By understanding the place as polyphonic in its foundation, planners could learn about the symbolic elements and reasons for people’s place attachment, and thus end up re-writing the place together. Urban interventions such as urban densification should connect to the place as part of its polyphonic historical continuum and acknowledge the residents’ place attachments.

Abstract:
<p>Architecture in permanent transformation is the starting point of this article, focused on the interaction between material and social aspects of a case study on modern Mexican housing, observing the building’s life in relation to its inhabitants. The Multifamily Apartment Building for Teachers (Multifamiliar para maestros), a faculty housing building at the UNAM campus, is a mid-twentieth-century experimental housing project, developed at the beginning of Mexico City´s densification. Today it is registered in UNESCO’s World Heritage Sites. The case study sheds some important insights into the transformations of a spatial modern utopia facing inhabitants' needs. Numerous differences were detected between the original idea behind the building’s architecture and the reality of its users today, revealing not only the ambiguous nature of the building but also problems derived from the country’s accelerated modernization. The results show contrasting approaches of the intermediate space between the building’s conception, and the constant process of becoming a home, where the scope of its habitability is negotiated. </p>

Abstract:
Syfte: I Sverige råder det en stor bostadsbrist. En lösning för att skapa nya bostäder i tätbebyggda områden är vertikal förtätning. Detta kan ske via våningspåbyggnad av bostäder på parkeringshus. Denna typ av påbyggnad ställer dock krav på den befintliga byggnaden. Rapportens syfte är att fungera som ett underlag vid projektering av konstruktion, brand och installationer vid framtida projekt av liknande slag. Målet är vidare att analysera och sammanställa olika byggnadstekniska lösningar som används vid våningspåbyggnad av bostäder på parkeringshus. Detta skall besvaras genom följande frågeställningar: Vilka konstruktionstyper tillämpas vid våningspåbyggnad på ett parkeringshus och vilka krav ställer påbyggnaden på den befintliga stommen? Vilka brandkrav ställs på denna typ av våningspåbyggnad och hur uppfylls dessa? Hur förses påbyggnaden med installationer?   Metod: Rapporten bygger på en kvalitativ fallstudie där intervjuer och dokumentanalyser legat till grund för empirin. För att styrka studien med teori har en litteraturstudie genomförts.   Resultat: Resultatet visar att en lätt stomme har använts till samtliga våningspåbyggnader, däremot har valet av stommaterial skiljt sig åt. Kapaciteten på den befintliga byggnadens grund har varit avgörande för om en våningspåbyggnad varit möjlig. Placering av våningspåbyggnaden har berott på om boyta eller antalet parkeringsplatser prioriterats högst. Brandkraven på denna typ av byggnad kan likställas med kraven som ställs på en nybyggnad av bostäder. Detta har inneburit att förändringar på de befintliga parkeringshusen varit nödvändiga för att uppfylla kraven. Nya installationsschakt har placerats både in- och utvändigt av den befintliga byggnaden.   Konsekvenser: De slutsatser och rekommendationer, utifrån rapportens innehåll, består främst av vikten i att göra en noggrann inventering av den befintliga byggnaden. Det handlar om byggnadens kapacitet och vilka eventuella förstärkningsarbeten som krävs innan en våningspåbyggnad.   Begränsningar: Studien avgränsar sig från byggnadstekniska beräkningar och ekonomiska kalkyler. Arbetet har begränsats utifrån en viss mängd ord och tidsram, utan dessa hade möjligheten funnits att göra en mer djupgående analys av studiens referensobjekt. Detta genom att intervjua ytterligare aktörer inom fler konsultområden för de valda referensobjekten.
Purpose: In Sweden, there is a shortage of housing and a solution for creating new housing in urban areas is vertical densification. Vertical densification can be done by adding floors of housing on top of existing parking garages. This type of extension sets demands on the existing building. The purpose of this thesis is to serve as a basis for the planning of construction, fire requirements and installations for future similar projects. The goal is furthermore to analyze and compile various building-technical solutions that are used when floors of housing are built on top of existing parking garages. The goal is answered by the following questions: Which types of construction are used for additional floors of housing on top of parking garages and what requirements does the extension have on the existing building? What fire requirements are imposed on this type of extension and how are they fulfilled? How are the additional floors of housing provided with installations?   Method: The report is based on a qualitative case study in which interviews and document analysis formed the basis of empirical data. To confirm the study with theory, a literature study has been conducted. Findings: The result shows that a light framework has been used for additional floors of housing, however, the choice of framework material has been different. The capacity of the existing building's foundation has been vital for whether an extension with housing has been possible. Placement of the extension has been due to whether the living space or the number of parking spaces is given as the highest priority. The fire requirements for this type of building can be equated with the requirements imposed on a new building of housing. This has meant that changes to the existing parking garages have been necessary to meet the requirements. New shafts for installations have been placed on both inside and outside of the existing building. Implications: The conclusions and recommendations, based on the content of the thesis, consist primarily of the importance of making an accurate inventory. It’s about the existing building's capacity and what possible reinforcement work it requires before an extension with housing. Limitations: The study delimits itself from construction engineering calculations and economic calculations. The work has been limited based on a variety of words and timeframe, without these it would be possible to make a more in-depth analysis of the study's reference objects. This would be done through interviewing more actors from additional consulting areas for the selected reference objects.

Abstract:
La population mondiale fait face, globalement, à une urbanisation expansive. Cet étalement urbain, souvent mal contrôlé, menace aussi bien l’environnement que la santé, la qualité de vie et la sécurité alimentaire des humains. Il est possible de le limiter en lui préférant la densification urbaine. Néanmoins, la complexité des phénomènes en jeu dans un tel contexte nous incite à penser que les responsables d’opérations de densification urbaine ont besoin d’outils pour les aider à faire les choix les plus pertinents possibles. Dans un premier temps, l’état de l’art présenté dans cette thèse montre que l’outil idéal n’existe pas, et que l’optimisation multicritère par algorithme génétique est une technique adaptée à l’aide à la conception de bâtiments. Les caractéristiques souhaitables pour une méthode d’assistance des concepteurs de projets de densification urbaine sont alors précisées. Nous recommandons de baser cette méthode sur le couplage entre un algorithme génétique et un outil capable de réaliser des simulations thermiques dynamiques (STD) de quartiers. Les capacités des logiciels de STD Pleiades+COMFIE (P+C) et EnergyPlus (E+) sont situées par rapport à ces exigences, puis un premier test d’optimisation d’un projet de densification urbaine en associant EnergyPlus à un algorithme génétique est présenté. Certaines lacunes de cette méthode peuvent être comblées par la plateforme en cours de développement dans le projet ANR MERUBBI. Dans un second temps, nous analysons donc les résultats d’une étude comparative entre P+C, E+ et l’outil MERUBBI, menée sur un projet de densification d’un îlot à forte densité urbaine. Ils montrent que ce dernier est fiable et particulièrement pertinent pour l’évaluation précise des interactions entre bâtiments. Dans un troisième temps, nous abordons la problématique de la diminution des temps de calcul, enjeu crucial pour que notre méthode d’aide à la conception soit réellement accessible aux professionnels du bâtiment. Nous proposons une technique de réduction de la période de simulation que nous présentons en détail. Enfin, la méthode d’optimisation développée est appliquée à la résolution de différents problèmes de conception du projet sus-cité, en utilisant E+. Nous montrons en quoi l’utilisation de l’outil MERUBBI enrichira cette approche, avant de conclure sur des perspectives de développement de notre méthode pour améliorer son interactivité
The world’s population is facing an expansive urbanization. This urban sprawl, which is often not well managed, is endangering the environment as well as human health, quality of life and food security. It can be controlled by favouring urban densification. Nonetheless, the complexity of the phenomena involved in such a context leads us to think that supervisors of urban densification operations need some tools to help them make the most relevant choices. This thesis begins with a literature review that shows the ideal tool does not exist, and explains why multi-objective optimization using a genetic algorithm is a suitable technique for building design aid. Then we clarify the desirable features of an assistance method for urban densification projects designers. We recommend to base this method on the coupling of a genetic algorithm with a district-scale dynamic thermal simulation (DTS) tool. We compare capabilities of EnergyPlus (E+) and Pleiades+COMFIE (P+C) DTS software with these requirements, then we present a first urban densification project optimization test associating EnergyPlus with a genetic algorithm. The platform under development in the ANR MERUBBI project can offset certain shortcomings of this method. Hence, in a second phase we analyze the results of a comparative study of P+C, E+ and the MERUBBI tool, carried out using a high-density district densification project as a test case. It shows that the latter is reliable and particularly relevant to precisely assess interactions between buildings. In a third phase we address the problematic of reducing the computing time, a major issue to make our design aid method truly accessible to building professionals. We propose a way of reducing the operating period length and present it in detail. Finally, our optimization method is used to solve various design problems of the above-mentioned project, using E+. We show how the use of the MERUBBI platform will enrich this approach before concluding with development ideas to make our method more user-friendly and interactive

Abstract:
Den befolkningstillväxt som sker idag skapar utmaningar för det befintliga bostadsbeståndet och vår bostadsförsörjning. För att klara tillväxten bygger vi våra städer tätare och högre vilket skapar både möjligheter och utmaningar. Ett sätt att effektivisera redan exploaterad mark kan vara att genom vertikal förtätning skapa fler bostäder på befintlig bebyggelse. Syftet med detta examensarbete är att belysa hur våningspåbyggnad i en urban miljö kan gestaltas och vilken påverkan den kan ha på mikroklimatet. För att undersöka huruvida det är lämpligt att förtäta ett utvalt objekt genomfördes en lämplighetsanalys baserat på ett tidigare examensarbete av Larsheim (2007), vilken behandlar inventering av fastighetsbestånd för vertikal förtätning. Denna metod har bearbetats i samråd med planarkitekt på Luleå kommun innan den tillämpades på det utvalda förtätningsobjektet vilket renderade i att byggnaden kunde anses lämplig att förtäta på. För att beskriva byggnaden och dess närområdes arkitektoniska karaktär utfördes en analys enligt Thiis-Evensen (1994) metod. Med hjälp av Pena och Parshalls (2001) metod ”Problem seeking” syntetiserades den arkitektoniska karaktärsanalysen tillsammans med förtätningsteori och teori om mikroklimat. Syntesen gav ett förslag till gestaltningsprogram för hur våningspåbyggnaden skulle kunna gestaltas. Examensarbetet resulterade i ett gestaltningsförslag se del 6. Gestaltningsförslaget. Påbyggnaden består av 45 lägenheter som är placerad ovanpå ett befintligt parkeringshus i Luleå, bostäderna är fördelade på tre plan vilka vilar på en förlängd pelarstomme. Påbyggnaden öppnar upp för nya möjligheter till ett attraktivt boende i innerstaden och har dessutom kvalitativa grönytor för lek och socialt umgänge samt odlingsbara ytor i ett växthus. I syfte att positivt kunna påverka de förändringar som kan ske då stadens tak bebyggs har mikroklimatsanalyser utförts utifrån faktorerna sol, vind, luftkvalitet, ljud, snö samt fenomenet ”Urban heat islands”. Analyserna som utförts har påverkat val av form och material för det i del 6. presenterade gestaltningsförslaget. Det presenterade gestaltningsförslaget bör i ytterligare steg undersökas av annan part då detta inte kunnat utföras under examensarbetets gång. Den lämplighetsanalys som testats i detta examensarbete bör valideras och utformas i närmre samarbete med intressenter och kommun för att säkerställa att rätt kriterier och tillvägagångssätt används då lämplighet för påbyggnad ska bestämmas.
The current ongoing population growth creates challenges for the existing housing stock and our housing supply. To handle this population growth, our cities are being constructed higher and more densely, which creates new opportunities and challenges. One way to make use of the already exploited land could be by using the principle of vertical densification to raise the existing building height and thereby being able to create new housing opportunities. The purpose of this master thesis is to illustrate how a rooftop extension could be configured into an urban environment and what impacts this configuration might have on the microclimate for the subjected area. To study the eligibility for a densification on the selected object, a method of eligibility analysis was carried out. The method used is based on a previous degree project by Larsheim (2007), which deals with stocktaking and assessing property stocks for vertical densification. The redesigned method was before being used on the selected object for densification drafted in consultation with planning architect at Luleå municipality. The final usage of the method resulted in the building being considered suitable for densification. A site analysis was conducted with regards to the existing building and its vicinity with a method written by Thiis-Evensen (1994). The method is focused on describing the architectural nature of the site. This analysis, together with the selected theory of densification and microclimate, was synthesized using Pena and Parshall's (2001) method "Problem seeking", which rendered a suggestion of a program for how the building could be configured. This master thesis resulted in a design proposal for a rooftop extension, see part 6. Gestaltningsförslaget. The extension is located on top of an existing multistory car park building in the centre of Luleå. The rooftop extension contains 45 apartments and consists of three elevated planes that resides on an extended pillar construction. A large green open area on the inner courtyard unlocks new opportunities for an attractive accommodation in the inner city. It also give the residents a room for social play and interaction as well as the opportunity to use cultivable surfaces in a new greenhouse. A microclimate analysis was carried out based on solar, wind, air quality, sound, snow, and the phenomenon of Urban heat islands in order to positively change the impact that might occur when the city’s rooftops are being extended. The analysis carried out influenced the selection of form and material in the design stage for the design proposal presented in part 6. The design proposal presented should be further investigated by another party. The eligibility analysis conducted in this master thesis should be validated and designed in close collaboration with stakeholders and municipalities to ensure that the correct criteria and approaches are being used when the eligibility of the rooftop extension is to be determined.

Abstract:
Idag förekommer bostadsbrist i flera delar av landet. Förtätning kan vara en strategi för att motarbeta bostadsbristen. I miljöer där kulturvärden uppträder finns en viss känslighet för exploatering. Syftet med studien är att undersöka hur förtätning på en fastighet kan anpassas till omkringliggande kulturmiljö och samtidigt bidra till god livskvalitet. Målet är att ta fram kriterier för nybyggnation i kulturmiljö som kan användas som underlag vid exploatering. Ett gestaltningsförslag tas också fram som grundas på de framtagna kriterierna. Arbetet är avgränsat till Strömsbro, Gävle och studien har exemplifierats på fastigheten Strömsbro 37:2 som är lokaliserad i området. För att analysera områdets kulturhistoriska värden och ta fram framtida utvecklingsmöjligheter har DIVE använts som metod. Den utförs i fyra steg: beskriva, tolka, värdera och aktivera/möjliggöra. I analysmetoden har platsbesök och inventering genomförts för att skapa en uppfattning om området och för att identifiera värden. Intervjuer och enkätundersökning har också varit en del av analysen och bidragit till identifiering av värden, förståelse för platsens identitet och för att ta fram möjliga utvecklingar av området. En volymstudie har utförts och ligger till grund för planering av nybyggnation. Beräkning av volymer och exploateringstal i den omkringliggande miljön har tagit fram värden som använts som riktlinjer. Arbetet har tagit fram ett gestaltningsförslag av attraktiva bostäder med hänsyn till kulturhistoriska värden. Gestaltningsförslaget resulterade i två lägenhetshus, ett radhus och en komplementbyggnad som följer traditionell utformning med moderna detaljer. Det framtagna resultatet kan inte representera allas åsikter om bevarande av kulturmiljö, eftersom åsikter och erfarenheter är subjektivt. Subjektiviteten kan uppröra medborgare av den orsaken att kulturmiljö är ett känsligt ämne. Därför bör medborgare involveras i ett tidigt skede av planeringen. Egenskaper i den fysiska miljön som är viktiga vid planering av nybyggnation i kulturmiljö är färgsättning, material, placering av bebyggelse, gatustruktur, taktyp och höjdskala. Dessa kan värderas genom DIVE-analysen. Volymer och exploateringstal är också värdefulla i den fysiska miljön och är viktiga att beakta för att inte påverka kulturmiljön. Gestaltningsförslaget i studien visar hur nybyggnation kan implementeras i kulturmiljö med avseende till framtagna kriterier för att minska inverkan på värdefulla karaktärsdrag.
Today residential shortage occurs in several municipalities in Sweden. Densification could be a strategy to solve this problem. Areas where cultural heritage exists are vulnerable to new construction. The aim of this study is to examine how densification on a property could adapt to the surrounding cultural heritage and contribute to good quality of life. The objective is to form criteria for new housing in a cultural heritage environment as a foundation of exploitation. A visualization proposal has also been designed by the criteria. The study is delimited to Strömsbro in Gävle, Sweden and have been exemplified at the property Strömsbro 37:2 that is located in the area.   The method DIVE has been used to analyze cultural heritage values and to demonstrate future development opportunities. The DIVE-analysis is performed in four steps: Describe, Interpret, Valuate, and Enable. By performing site visits and inventory in the analysis, values have been identified and a perception over the area have been obtained. Interviews and questionnaires have also been a part of the analysis and have contributed to identification of values, to understand the sense of place and to clarify possible developments. Building volumes have been studied as another method of this thesis. Calculations of volumes and floor area ratio of the surrounding environment have provided guidelines for the visualization.   The work resulted in a design proposal of attractive new dwellings, considering the cultural heritage values and seclusion to reduce unwanted observation to create better qualities of life. The design proposal resulted in two apartment buildings, one townhouse and one complementary building that pursue traditional formation with modern details.  The result can not represent everyone’s opinion regarding cultural preservation. Cultural heritage is a sensitive subject and citizens might get upset with the result. Residents should therefore be involved in an early stage of planning.  Physical qualities that are important when planning for new housing in a cultural environment are coloring, material, building placement, street network, roofing and height scale. Volumes and floor area ratio are also important in the physical environment. The design proposal in this study shows how new housing could be implemented in a cultural district regarding the criteria.

Abstract:
Städer har under sin framväxt planerats på olika sätt. Från rutnätsplaner under 1600-talet till 1900-talets planering som resulterade i sovstäder separerade från arbetsplatserna. När städerna vuxit har de områden som från början låg i utkanten istället hamnat närmare stadens centrum. Gamla industriområden ligger som kilar i stadsbilden och genom att ändra användningen av marken där kan nya bostadsområden växa fram. Dagens forskning visar på att en blandad struktur i bebyggelsen med bostäder, verksamheter och tät gatustruktur är vägen framåt. Är dessutom variationen stor vad gäller typen av bostäder finns det möjlighet att skapa ett område där människor kan trivas över tid och flytta mellan olika bostäder under olika skeden i livet.     Studien utreder hur ett område i Västervik, i studien kallat Lärkstaden, kan planeras för framtidens medborgare. Förslaget täcker en yta på 97 000 kvadratmeter som idag innefattar 12 fastigheter, ett koloniområde och grönområden. Här finns idag småskalig industri och handel. Även en del företag inom byggbranschen har sina lokaler i Lärkstaden och den angränsar till bostadsbebyggelse och grönområden. Genom att rita upp ett förslag på ny utformning undersöks vilka funktioner som kan samsas i Lärkstaden och hur bebyggelsestrukturen blir långsiktig. Förslaget förankras i tidigare forskning genom en litteraturstudie. För att få en större förståelse för platsen genomförs ett antal platsbesök och även intervjuer av personer som genom erfarenheter och kunskap bidrar med tankar och idéer.
Cities have been planned in different ways during their growth. From grid plans during the 17th century through 20th-century planning that resulted in quiet parts of the city that lacked life and vitality separated from workplaces. As the cities grew, the areas that were originally on the outskirts ended up closer to the city center. Old industrial areas are like wedges in the cityscape and by changing the use of the land there, new residential areas can emerge. The research today shows that an area with a mixed structure that contains housing, businesses, and a dense street structure is the way forward. In addition, there are great variations in the type of housing that can be constructed to create an area where people can thrive over time and move between different homes during different stages of life.   The study investigates how an area in Västervik, in the study called Lärkstaden, can be planned for the citizens of the future. The idea covers an area of 97 000 square meters which today includes 12 properties, a plantation area, and green space. Today there is small-scale industry and trade. Some companies in the construction industry also have their premises in Lärkstaden and it is adjacent to residential buildings and green areas. By drawing up an idea for a new design, an investigation has been carried out showing which functions can be shared in Lärkstaden and how it would become sustainable in the long-term as it will have the required mixed structure mentioned above. The idea is anchored by previous research through a literature study. To gain a greater understanding of the area, visits have been made and people have been interviewed through experience and knowledge offer thoughts and ideas.

Abstract:
I Sverige har det funnits en utbredd bostadsbrist under de senaste decennierna och utvecklingen har skett mot större förtätning, målsättningen är att skapa städer med ekonomisk- och socialhållbarhet. Det bortses dock från att tätt planerade städer riskerar att inskränka på dagsljustillgången för de boende. Nordiska klimat med mörka vintermånader och solen som står lågt på himlen skapar en stor utmaning. Forskning visar att god tillgång till dagsljus är viktig för människors hälsa och välbefinnande och det är därför viktigt att skydda dagsljustillgången för boende i svenska städer. Trots detta så är den svenska lagstiftningen för skydd av dagsljus för befintliga bostäder svårtolkad med vaga riktlinjer på vad som kan anses som en rimlig minskning av dagsljustillgång.Denna studie undersöker den aktuella lagstiftningen i Sverige för skydd av dagsljusåtkomst i befintliga byggnader. Med fokus på befintliga bostadshus används resultatet från fördjupade fallstudier över två områden för att undersöka möjligheter för hur en framtida kravställning kan se ut. Förslaget på kravställningen diskuteras med hänsyn till nuvarande praxis.Studiens resultat påvisar att en förtätning av staden i många fall leder till otillräcklig dagsljustillgång i befintliga bostäder och att dagens kravställning för dagsljushantering är bristfällig. Att säkerställa tillräcklig dagsljustillgång i bostäder är nödvändigt redan vid planläggning. Studien visar på ett varierande resultat vid användning av nuvarande föreskrifter och allmänna råd givna av Boverket och den europeiska standarden SS-EN 17037:2018. SS-EN 17037:2018 påvisar ett resultat som är känsligare för förändringar i omgivningen. I kombination med att standarden beskriver den faktiska upplevelsen av ljuset i rummet gör det den till ett lämpligare mätetal för dagsljushantering. Om visionen för framtidens städer ska vara samma som idag bör kravställningen på dagsljus utvecklas.
Over the past couple of decades Sweden has suffered from a housing shortage and the trend towards densification due to ambition of creating cities with economic and social sustainability. It is often missed however that tightly planned cities run the risk of restricting daylight access for occupants. Nordic climates, with their relatively low solar angles and dark winter months pose a particular challenge. An increasing body of research however shows that good access to daylight is crucial to human health and well-being. As such, it stands to follow that protecting daylight access for those living in the city is of great societal benefit. Yet the current Swedish national regulatory structure for protection of daylight access in existing properties gives only vague guidance as to what constitutes an unreasonable reduction of daylight access and/or remedy when an unreasonable reduction in daylight access exists. The resulting uncertainty presents a degree of unwelcome risk to building projects.This study reviews the current state of Swedish legislation for protection of daylight access in existing buildings. With focus on residential buildings it uses results from in-depth case studies to examine possible structures for what a future regulatory framework might look like and discusses the proposal in the context of current Swedish praxis.The study found that in many cases, densification of the city leads to insufficient daylight in existing housing and that today's requirements for natural daylight are inadequate. Ensuring adequate daylight is possible already when planning and should be considered to create a society where human health is secured. The study shows varying results when using current Swedish regulations and the European standard SS-EN 17037:2018. SS-EN 17037:2018 demonstrates a result that is more sensitive to changes in the environment, combined with the standard describing the actual experience of the light in the room making it a more suitable measurement for assessing changes in daylight access for existing properties.

Abstract:
The diploma thesis deals with the construction and activation of the territory in connection with the historical center of Kyjov. Part of the proposal was to work with an existing urban brownfield and an extensive park, which accounts for almost half the area under consideration. The goal, as I set out in my work, is to activate the territory and design an urban sprawl with a suitable functional structure. The proposed design respects the context and character of the site in a modern and sustainable manner. The principles followed in my work are based on the current urban and city-forming rules. I have put an emphasis on the human scale, the priority of pedestrians over traffic, and especially the shortcomings and needs in the territory that arise from the analysis. The draft concept is based on the permeability and interconnection of the individual parts of the city, the insertion of a new public space and the completion of the city block. The new urban sprawl clearly defines the street, completes the boundaries and makes the most of the area on the released land. The newly designed buildings are residential and multi-functional houses with active parterres. Part of the proposal is the revitalization of the city park, which explores its hidden potential. The basic step is to remove obstacles in the permeability of the park and to highlight its strengths, such as the flowing river Kyjovka, healthy large trees and the size of the park itself.

Abstract:
Several automatic methods exist for creating 3D point clouds extracted from 2D photos. In manycases, the result is a sparse point cloud, unevenly distributed over the scene.After determining the coordinates of the same point in two images of an object, the 3D positionof that point can be calculated using knowledge of camera data and relative orientation. A model created from a unevenly distributed point clouds may loss detail and precision in thesparse areas. The aim of this thesis is to study methods for densification of point clouds. This thesis contains a literature study over different methods for extracting matched point pairs,and an implementation of Least Square Template Matching (LSTM) with a set of improvementtechniques. The implementation is evaluated on a set of different scenes of various difficulty. LSTM is implemented by working on a dense grid of points in an image and Wallis filtering isused to enhance contrast. The matched point correspondences are evaluated with parameters fromthe optimization in order to keep good matches and discard bad ones. The purpose is to find detailsclose to a plane in the images, or on plane-like surfaces. A set of extensions to LSTM is implemented in the aim of improving the quality of the matchedpoints. The seed points are improved by Transformed Normalized Cross Correlation (TNCC) andMultiple Seed Points (MSP) for the same template, and then tested to see if they converge to thesame result. Wallis filtering is used to increase the contrast in the image. The quality of the extractedpoints are evaluated with respect to correlation with other optimization parameters and comparisonof standard deviation in x- and y- direction. If a point is rejected, the option to try again with a largertemplate size exists, called Adaptive Template Size (ATS).

Abstract:
Contemporary urban planning for the past decades has concentrated on sustainable development, for instance through the promotion of dense development (Echenique et al., 2012). Important components for sustainable urban development concerns increasing residential and building density, as means of counteracting the consequences of urban sprawl (Jenks and Jones, 2008). Because it is argued that high-residential density is more economically, environmentally and socially sustainable than low-density since a higher concentration of people contributes to for instance shorter transportation distances as well as makes services and amenities more economically viable  (Frey, 1999; Haughton and Hunter, 2004). However, whether the densification of cities has desirable or undesirable social, economic and ecological impacts is highly contested. The purpose of this study is to analyze the socioeconomic outcomes of the urban densification process in the Lundby District, Gothenburg, over time. Through a mixed method approach, statistical information for Lundby District, for the years 2008 to 2015 have been processed and two semi-structured interviews with employees in the City Planning Authority and Lundby District Administration were conducted. The densification in Lundby presents certain strengths, weaknesses, opportunities and threats. As more than 6300 new housing units has been constructed during this time-period, and more is to come in the near future, Lundby experienced a repopulation as the housing construction has facilitate a population increase of more than 11 000 new inhabitants. However, as the favored tenure developed during this time-period been condominiums certain weaknesses exist. Nonetheless, densification and the rapid increase in population has contributed to the number of vehicle per 100 inhabitants decreasing, which presents opportunities for being more environmentally friendly. On the other hand the claim that through densification could diversity and social mixing be achieved is flawed, as seen in Lundby the densification process has brought changes in population structure and socioeconomic characteristics, which suggest some form of gentrification is occurring.

Abstract:
Santiago de Chile´s areas of growing centrality are currently under residential densification processes, which vary in degrees of intensity and forms of impact in the urban environment. As a result of a weak conduction of residential densification, the structural-radical transformation of the urban fabric has resulted in urban space degradation. However, residential densification is a form of urban growth that, well designed and planned, allows optimizing infrastructures and building a more complex and inclusive city. This work aims to understand to what extent urban morphology shapes these processes of urban transformation in 15 selected areas of 25 hectares; proposing typologies of residential densification based on the intensity of the process and the state of transformation of the urban fabric. Density (dwellings/hectare) is understood in systemic relation with those parameters that determine urban compactness and configure public space: lot subdvision composition, setbacks, building footprint and height, floor area ratio and mixed use index, among others. The impact of intensive densification on urban space would have three main effects: (1) the standardized tower radically fragments the fabric structure and skyline, to the extent multiple and dispersed vertical operations transform lot geometry, abruptly increase building height and lower land occupation; (2) triggers a "residentialization" effect, unbalancing existing diversity of activities and contributing to undermine urban vitality; and (3) impairs the quality of public space, by introducing exogenous typological elements (such as setbacks) and reducing contact between private space and the street.

Three-storey timber building with the platform framing method of major structural member’s joining of was considered as an object of investigations. The length and width of considered building were equal to 28 and 13 m, correspondingly. Simplified approach of load-bearing shear wall modelling, which is based on the replacement of the shear wall structure by the lattice structure with the equivalent stiffness, is presented. FEM models were developed by the softwares ANSYS 15.0 and Autodesk Robot Structural for verification of developed simplified approach. It was stated, that the difference between the horizontal displacements obtained for single member of shear wall structure by the developed simplified approach and developed FEM models does not exceeds 5%

The development of skyscrapers has been one of the solutions to address the problem and, more often than not, new structures are being built directly over the extensive network of underground infrastructure in the city.</p><p>The presentation showcases the experience and lessons learned from a selection of projects in the US and UK located directly on top of existing infrastructure. Examples include NYC transit projects spanning from the 1990s, when nine buildings along Riverside Boulevard and on top of the former Penn Central rail yards were developed, to the ongoing Atlantic Yards/Pacific Park project where up to six buildings will be erected on top a 320,000sqft platform over train tracks. Amongst other projects, the presentation will include the Hudson Yards development on the east side of Midtown Manhattan located over the subway entrance to the 34th Street station and the Waterline project built over the AmTrak and LIRR train tracks. In the UK case studies include two recent London projects at Royal Mint Gardens and Principal Place. The general focus is aimed at the structural strategies employed and their impact not only in construction costs but also the long-term effect in the urban fabric.</p>

Abstract:
<p>Ground improvement has become one of the most effective tools of geotechnical engineering, being adopted for an always larger variety of civil engineering applications. To reduce the role of subjective choices of operators, the use of different techniques tends to be codified by specific guidelines. In the European Union there is an ongoing effort to standardize execution and design within codes continuously reviewed by designated committees. A widespread and systematic standardisation on the ground improvement as a mean to mitigate the effects of liquefaction on buildings and infrastructures is missing. The paper presents and overview of traditional and new ground improvement technologies suitable for this application. The methods are firstly classified by considering their effects on the ground (e.g. densification, stabilization, drainage, desaturation, etc.). Design principles are then outlined for new or pre-existing buildings and infrastructures, considering the ongoing review process of the design Eurocodes.</p>

Abstract:
<p>Earthquakes induced liquefaction is one of the most significant causes of damage to structures during an earthquake. Ground improvement is currently considered to be the most appropriate mitigation tecnique to prevent soil liquefaction. This work is aimed to compare different liquefaction mitigation techniques for protection of small-to-medium sized ‘critical’ infrastructures and low-rise buildings. The effectiveness of some techniques (densification, addition of fine contents, induced partial saturation and drainage systems) was verified via experimental evidences coming from laboratory testing, physical modelling and liquefaction field prototype tests. Starting from the calibration of advanced soil constitutive models, numerical modelling activities were extended to the back-analysis of centrifuge tests and field prototype tests, up to a parametric study with different geometrical layouts.</p>
