Densification is one of the urban visions for sustainable development - a vision that has become a part of the solution to the unsustainable sake dilemma. With the dense city land will be saved, energy consumption reduced and social cohesion improved. The dense city is considered to be ecologically, economically and socially sustainable. Applying an urban design concept has thus proven to be problematic. Density has been found to be a complex concept which is far more complicated than measuring how much built surface that needs to be covered. It is also not disputed what different degrees of Densification mean and whether Densification in itself is sustainable.

Urban Densification as a planning strategy is of interest in the planning context of today. It is also seen as a part of the sustainable development. Urban Densification as a concept is commonly used in the discussion of a sustainable development. Thus, the question about urban Densification is an important challenge in the current planning context. A deeper understanding of the process which urban Densification has developed from is necessary, since planners then will be more able to manage this challenge.

An ever-increasing population, urbanization and visions towards sustainable cities clarifies the need of Densification. When densifying existing urban areas adding storeys could serve as a residential Densification, which would also meet the market demand for centrally located apartments. An increased understanding of the potential of vertical Densification gives way to the aim of this thesis to increase the amount of centrally located housing.This thesis provides knowledge of adding storeys and how property owners can identify opportunities in their existing building stock.The first question, What kind of residential Densification takes place in Sweden today? highlights ways of residential Densification; development of brownfields, infill and adding storeys, where adding storeys is what this thesis then focuses on. The result came through a literature review that also clarified important factors when adding storeys.

Due to an increased population in cities the need of Densification of cities increases. This means that the amount of ecological elements in the city is at risk of decreasing. Ecological services contribute to the city?s climate by softening the negative impacts that Densification of cities means. Thus increases the will and ambition in city planning in to preserve greenery.This is an interdisciplinary thesis within the subject of geography that studies Biotope Area Factor (BAF), a planning tool that is used in city planning with the purpose of compensating for lost ecological services associated with new housing estate.

Fuel pellets are in Sweden mainly produced from sawdust and cutter shavings. Before the pelletising process the raw material is dried to attain consistent moisture content and ground up in a hammer mill. In the Densification process (pelletising) the ground material is forced through holes in a rotating die. This heats up the wood particles which cause them to soften and self bond. After the process the pellets are cooled, sieved and bagged. The milling process creates a wide range of particle sizes.

The number of inhabitants of the towns and city centers have generelly increased, concurrent as the population in smaller towns has decreased. In Stockholm, the migration is very fast and here is also the most populous place, if one compares with other Sweden. In order to respond to the increasing population and the pressure they put on city spaces has Stockholm's town a town building strategy that says "build inwards". It means that one stem seals the town with spaces and business activities in central locations. The increased population in the towns and the Densification of buildings leads however to an increased pressure on parks and public places.

Wood pellets are an upgraded product of residuals from several wood processing industries, for example saw mills and pulp industries. The pellets are produced by pressing the milled and dried sawdust to cylindrical units with a higher density than the initial raw material. Pellets have great benefits compared to the raw material: high energy per volume, good transport and storage properties and homogeneity. Several parameters collaborate in the whole process, which makes it complex. Wood is a heterogeneous material, chemically and structurally dependent on wood parts, habitat and storage procedures.

Rörelse i staden är avgörande för hur staden fungerar. Platser och stråk med stora flöden har annorlunda förutsättningar än platser och stråk med små flöden. Flödena påverkas i sin tur av stadens struktur.  Det här examensarbetet handlar om hur förtätning kan vara en del i en medveten förändring av stadsstrukturen och hur man genom förändringar i stadsstrukturen kan skapa varierande rumsliga förutsättningar som kan utgöra ett ramverk för framtida utformning.Föremålet för den här studien är området runt Årstabergs pendeltågsstation i södra Stockholm. Området är en viktig kollektivtrafikknutpunkt och många människor passerar här dagligen för att byta mellan olika kollektivtrafikslag.

Umeå är en växande stad som ligger längs norrlandskusten. Kommunen har starka mål och ambitioner för att staden ska växa de närmaste 25 åren. Kommunen planerar att komplettera ett område vid namn Berghem med 80-100 lägenheter. Ett helt nytt kvarter ska bildas på nuvarande naturmark i sluttande terräng. Kvarteret ligger nära Umeå centrum och bara ett stenkast ifrån Berghems eget centrum.

If one looks at physical planning in Sweden today one can see that while talking about Densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.

The effect of climate change places demands on how we build cities. Cities have to be built denser to meet the objectives of sustainability but as a result of this Densification city green areas are at risk of exploitationand disappearing. The question this raises is whether there has to be an opposition between a dense and a green city?Urban trees are playing a very important role in cities. They stand as the major part of the vegetation in citieswhich are otherwise dominated with concrete and stone.

Today's planning strategy, Densification of cities, makes it difficult for municipal authorities to find spaces to build preschools and daycare centers on. The Planning and Building Act , Chapter 8, § 9 states that " if the site should be developed with buildings that contain one or more dwellings or premises for after-school , preschool, school or other activities, it should be on the property or near it, enough free space which is suitable for play and being outdoors. " Each municipality has to define the expression enough free space and a number of municipalities have established guidelines for preschool and daycare centers concerning dimensions. The guidelines measure the number of square meters of free space per child with the aim of contributing to a qualitative environment. But the size is just one quality and the issue is how other non-quantifiable qualities are taken into account in the planning process. The paper compares three municipalities, Gothenburg, Malmö and Lund.

This thesis was done after a request from the county?s administrative board of Västmanland to provide the board with a better understanding of how green areas have changed within Västerås municipality over time.The purpose and goal of this study was thus to measure and analyze how much of the green areas within Västerås municipality that have disappeared during the past one hundred years as well as to provide a review of previous studies regarding the importance of green areas for humans as well as the biological diversity.In order to answer these questions I have in this study used a combination of a literature study, cartographic analysis as well as a time series analysis. The computer software used to do the measurements of the green areas was ArcGIS which is a geographical information system.In the cartographic and times series anlaysis measurements and analysis was made of the district map of 1911, the economic map of 1950 and the property map of 2011. The measurements show that the municipality has grown with 46,3 km2 over the last one hundred years. New neighborhoods? have emerged and the municipality has expanded.
