    LED-belysning och brukaren2014Report (Other academic)
    Abstract [en]

    Lighting research is diversified and includes theory and methodology from disciplines as different as technology, medicine and social sciences. There is also an expectation on research results to be directly applicable in real environments. The introduction of LED has furthermore made previous research on incandescent lamps, fluorescent lamps and other light sources, outdated.    New knowledge – and new research – is needed.

    An inventory of current LED-research was made during 2013. The result of this inventory is the basis of the research review here presented. The presentation includes more than 400 articles, reported under the headings: The biological clock; Flicker and dimming of LED: Energy efficiency: daylight and lighting control; Colour rendering; Glare, and finally; Perceived lighting qualities.

    Underlying theoretical considerations as well as actual knowledge are presented in the text of the different sections, and references are given to relevant research publications. All publications have been provided with two or more keywords in Swedish, describing the content of the publication. After the text given under each heading the references supporting this text are presented. In the final section all LED-publications are given in alphabetical order according to author and with keywords.

    Abstract [en]

    We need more research about what gives man good conditions for quality of life in a home environment. Social sustainability is a topic that is cherished more than ever in the world of architectures. The goal is to develop a knowledge base based on the experiences of users, architects and clients that can be used for the design of residential areas with apartment buildings.

    To achieve the goal there are questions to be answered as: "How is socially sustainable housing valued, according to architects and clients, when residential areas with apartment buildings are designed?" and "How are the values of social sustainability perceived, in residential areas with newly constructed apartment buildings, of the residents?" The questions are answered by means of an survey and several of interviews which together constitute a qualitative research.

    The results show that social sustainability can be seen from different angles. It is common to observe social sustainability from a community perspective and from an urban perspective according to scientific references. As an overall summary it is the beautiful shape and appearance of a building and its functionality weighed in with a reasonable cost that creates a socially sustainable housing according to interviews with architects and clients. It is about balance between beauty, functionality and economy, which together create a housing that lasts over time and confirms the human social dignity. According to those living in the area of Nysäter in Mölnlycke as the studied phenomenon, socially sustainable housing stands for comfort, security, privacy and community. Access to nature and outdoor activities, fresh air and good neighbourship are other factors that are highly valued. Socially sustainable housing has therefore connections to both physical parameters as well as non-physical qualities that needs to be linked with each other.

    The summarized results highlight the essential aspects that should be included in the planning of a new residential complex for it to be socially sustainable for residents. The knowledge base has a logical order from analyzing an unspoilt area with its qualities to analyze how the private residence must meet human needs for well-being.

    The Report is wide in its choice of subject tough it is limited to man's relationship to the dwelling and residential area in social contexts, how individuals perceive their environment both in and outside their home. With additional constraints had a deeper research been able to implement on a specific theme.

    Kartläggning av sex kommuners planering av kollektivtrafiken i nya bostadsområden inom Jönköpings län2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: Today we can see a steady increase in population, which calls on the municipalities to plan new residential areas and develop the old ones. This in turn leads to pressure on public transport with a focus on environmental issues and a desire for a different way of transport than by car becomes more and more relevant. The purpose is to give an overview and to understand the planning of public transportation today for six municipalities in Jönköping County.

    Method: The report has been conducted using qualitative studies in the form of interviews and literature studies. Document studies have also been used and have been downloaded from the municipalities' websites. Findings: When planning new residential areas, the municipalities try to bring public transport into account. In some municipalities, public transport has a more significant part in planning. If the municipality fail to achieve the aims of public transport planning, it will mainly result in negative environmental impacts. For the municipality to develop and make sure that the number of inhabitants increases, public transport should be an important part of the planning. When it comes to the cooperation between Jönköpings Länstrafik and the municipalities, they focus on public transport and that It will cover the need for travel in the municipalities. It is important that you already in the early stages of planning make sure that there is room for the public transport that is required.

    Implications: Public transport must continue to be a major part of planning and focus should be on realizing what is planned for public transport. Although the municipalities are planning public transport, there are residential areas that could have a significantly better access to public transport.

    Limitations: As time was not enough for a study covering all 13 municipalities in Jönköping County, it was decided to focus only on six municipalities with different circumstances and varying sizes.

    Vägnätsanalys i Jönköping: Fokus på cykelvägarna2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: In a world with an increased awareness of the harm caused by traffic to the environment and health, it is preferable that more people choose cycling instead of driving. The purpose of this work is to create an attractive city environment for cyclists which will give a greater sense of security and leading to more people considering the use of bicycles. Method: The methods chosen to make the analysis is to check the demands and recommendations from Trafikverket, moreover make observations according to Mini Cycleability Index in order to see if the West Center of Jönköping is attractive to cyclists. Geographical Information systems has been used as a method for data collection and analysis. At last an interview was held with Jönköping municipality to discover what future plans they have regarding the studied area and how relevant the plans are with the findings of this research. Further purpose of the interview with the municipality was to see how they perform a road-network analysis and obtain an opinion on the analysis performed in this paper. Findings: The results show that the road system in Jönköping West Center has roads of shifting qualities. The grades have been split into three; great, good and poor. Great being the highest grade and poor the lowest. The three qualities of roads do exist within the area, however the poor roads appear to be more frequent than the others. The evaluation system is built upon how well the roads perform in the categories: space, safety and continuity. Implications: The conclusion of this work is that there are several roads as graded poor within the area that need to be considered for reconstruction to create an attractive area for cyclists. In the area the results showed that the roads graded as great mostly runs from north to south and few exists from east to west. Due to this it is difficult to bike within the area as the connectivity between the great graded roads are lacking. Limitations: The investigation is limited to the choice of the area (Jönköping West Center) and the aspects analyzed which are safety, space and continuity. Due to the time aspect further limitations on data collection has come, where a measurement of cyclists and a survey could have been useful to do. In order to suit the Cycleability index with the choice of area and the methods available to use, there has been a reduction of the amount categories evaluated

    Klassificeringssystem för hållbar stadsutveckling2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The urbanization is increasing while there is a comprehensive climate change in the world. The cities stands for 70 percent of the global carbon emissions and two-thirds of the world's energy use. Half the world's population live in cities. Because of this, it is necessary that cities are sustainable. Therefore, there are various classification systems for neighborhoods that facilitates the creation of a sustainable city. However, there is no Swedish system but Breeam Communities is adapted to Swedish conditions.

    The objective of the report is to contribute to the development of methods that support sustainable urban development. By first identifying the classification systems, these could be compared with each other to see which criteria’s recurred. Parallels could be drawn as to which was more important, as the majority made use of these criteria. A sketching was made to find out what criteria should be included in the Swedish system and the regular criteria of the investigated classification systems were also very helpful.

    The systems that have been investigated are Breeam Communities, Casbee for Cities, One Planet Communities, Green Star Communities and Leed for Neighborhood Development. The systems measure sustainability usually infactors/criteria of social, economic and ecological aspects. Classification systems have different requirements or goals of what needs to be achieved within each factor. The systems are very different designed which complicated the comparison process.

    The regular criteria in all systems are carbon, water consumption, water pollution, food, wildlife and nature, floods, waste management, developed land, physicalactivity, accessibility, health and welfare, culture and heritage, transport, greenspaces, community involvement, light pollution, local economy and employment.

    Since Sweden has its own climate and its own standards, a foreign system is not adapted so easily to Swedish conditions. The criteria that should be part of a Swedish system is partly based on the global and national goals for Sweden as wellas those returned in the analyzed systems. In addition to the criteria that reappeared in the systems (some of the criteria has been renamed) it should also contain noise, nature, traffic, mixed development, security, maintenance and education.T

    There are many factors within the three perspectives to be analyzed and utilized to achieve a well-organized and good classification system of neighborhoods. There are many benefits of a classification system. For example, it facilitates informed choice, collaboration and communication between actors, but most of all a better society to live in.

    En utredning av kommunala markanvisningspolicyer: Påverkan av lag 2014:8992016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det är sedan tidigare tydligt att det funnits problem och delade åsikter kring arbetet med markanvisningar innan lag 2014:899 trädde i kraft. Arbetets syfte var att undersöka om arbetet har förändrats efter att lag 2014:899 trädde i kraft. Målet med arbetet är att utreda de valda kommunernas markanvisningspolicyer och deras erfarenheter av arbetet med dessa. Förbättringsåtgärder föreslås efter att ha belyst svagheter i de markanvisningspolicyer som undersöktes, med utgångspunkt i lag 2014:899 samt punkter specificerade av Caesar et al. (2013). 

    Ett dokument med förslag till vad en markanvisningspolicy bör innehålla har tagits fram. Dokumentet kan underlätta kommuners arbete med markanvisningspolicyer i fortsättningen.

    Underhåll av levande väggar: Möjligheter och utmaningar i ett svenskt urbant klimat2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: A slow development of living walls in Sweden is partly due to lack of experience and knowledge in the construction industry. Former studies point at challenges of adapting the technique in a Swedish climate and the importance of planning, knowledge and cooperation for the maintenance. The objective of the study is to analyse a sustainable maintenance by technique and maintenance planning of the system living walls in order to answer these challenges.  

    Method: The study is based on a qualitative approach where the methods are document analysis, interview and observation. Document analysis gives a status report of the implemented living walls in Sweden and introduces strategies for maintenance planning. Interview with relevant participants contributes with experiences concerning technique, maintenance and maintenance planning. Observation confirms the information about the technique.

    Findings: The study shows that none of the observed solutions can be considered completely sustainable, though they do have some sustainable qualities. Living walls have strong social and ecological benefits, where the vegetation contributes to increase ecosystem services in urban environment. A less use of resources is necessary for a sustainable technique where the use of stormwater, local resistant plants, lasting construction and recycled components promotes a sustainable environment and economy. The felt system is simpler in its design while the modular system is more flexible. A common objective among the observed projects is to create a maintenance-free solution as possible. Acceptance for resting plants during winter can lower the demands of the maintenance. Technical monitoring facilitates the maintenance but the manual handling of living walls is crucial. The frequency of the maintenance varies from each project where the client’s choice, placement of the wall, type of solution, size, plant choice and season affect. Therefore, it is important with planning and constantly evaluating a walls needs. The majority of the observed projects do not have a maintenance plan but the study shows success by a common objective, site analysis, goal-oriented maintenance plan and experience feedback.

    Implications: The conclusion of the study is that the technique of living walls needs to be evolved to leave a smaller footprint on the environment and the economy. The development is towards a maintenance-free solution but the manual handling can not be replaced by advanced technique. Every projects individual conditions demands thorough planning and continuous evaluation of the wall.

    Limitations: The study discuss living walls in the Swedish urban climate, where the result is based on experiences from projects developed in the southern part of Sweden. Other geographical placement causes different conditions for technique and maintenance. General assumptions can be made concerning the maintenance planning. More interviews with maintenance staff can contribute with other aspects to the analysis.

    Resilience in the supply and demand chain a new management strategy2012Conference paper (Other academic)
    Abstract [en]

    The length and complexity of the supply chain tend to increase, rather than diminish, thereby making the supply chain riskier and less predictable and, hence, more vulnerable. At the same time, customers are becoming increasingly demanding. The challenge to businesses today is to create a resilient supply chain in order to manage and mitigate risk and vulnerability. The purpose of this paper is to describe the use methods and tolls from quality and logistics can improve supply chain resilience. There are five principles that characterise supply chain resilience: risk management culture, agility, design-and innovation-led organisations, collaboration and spreading and anchoring of the vision, goal, values and methods. Using a combined quality management philosophy, the speed of process could be increased, and the responsiveness and flexibility could be improved, which means quicker response to changes. It has also been indicated that a combined quality management philosophy improves the companies’ resilience, due to their increased agility and strengthened ability to handle variability and risk management. Quality management tools can be very effective in the companies’ efforts to control supply chain risk and to identify risk sources of variation, even outside the focal company.

    Förbättring av tillgänglighet i tillgänglighetsanpassade naturreservat2014Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    More than half a million people in Sweden are affected by some sort of disability. During recreational activities in nature areas, these people might encounter difficulties such as inadequate accessibility. The Swedish society requires that all citizens should have the same possibilities. The purpose of this thesis is to improve the accessibility for people with disabilities. The aim is to examine occurring flaws in accessible nature reserves and suggest possible improvements.The questions that will be answered are as follows:• What flaws do accessible nature reserves have, and how do they affect the visitors?• What improvements can be made in nature reserves to increase accessibility?To answer the questions, a case study was done, where five different nature areas were visited. During the case study, various flaws in the accessibility were observed and analysed. Prior to the case study, requirements and scientific research regarding accessibility was studied. Using this, suggestions for improving the accessibility were made. . Most of the improvements that could be made in the studied nature reserves were presumed to be applicable in other nature reserves in Sweden.With the case study in mind, the accessibility was considered in need of various improvements. The accessibility was studied from three out of four of the Swedish disability association’s categories; physical, communicative, and informative accessibility. The flaws that were encountered in the studied areas were due to incorrect design, or insufficient maintenance. Most of the flaws could be corrected in simple ways, but the flaws that were due to incorrect design or planning would require more work. After the case study it was discovered that supposedly “accessible” trails, according to different websites, had varying levels of accessibility. An accessible recreational area will benefit all types of visitors, not only people with disabilities. It will be more convenient and enables visits with strollers. An area cannot be made accessible for all types of visitors, but can be made accessible for as many visitors as possible.

    Effektivisering av ekologisk dagvattenhantering i stadsmiljö2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In the city of Jönköping problems with the irregular flow, erosions and transport of sediment materials are recurring in the brook Strömsbergsbäcken. The problems is somewhat caused by an increased flow of storm water in the brook, which leads to high flow peaks in some parts of the brook since the original furrow is not dimensioned for the increased amount of water. The purpose of this project work is to make ecological drainage management in urban environments with a high amount of storm water discharge more efficient. The objective with the report is to create valuable material of how to accomplish ecological drainage management in urban areas and that the report will be useful for future similar connections. To fulfill the objective, the following three questions have been designed as a significant part of the final project report:

    • How can the load on the general drainage system be reduced?
    • How can the pollution effects of storm water runoff in urban areas be reduced?
    • Which treatments are appropriate to enhance the ecological storm water management in Strömsbergsbäcken ?

    The methods that have been used to solve these questions are document- and literature studies, and also a case study.The thesis results shows that the storm water flows from four of the nine areas that has its outlets in Strömsbergsbäcken, need to be treated through some kind of a solution or method that delays the water flow. The treatment could be performed in the area, before the storm water reaches the storm water network, which leads to Strömsbergsbäcken. The storm water flows can also be reduced by treatments adjacent to the outlets in the brook, where the largest flow peaks occurs. For example an essential solution to decrease the flows in Strömsbergsbäcken is to reconstruct the old dam located near one of the outlets into a basin, which will delay the stormwater flows.

    Abstract [en]

    The purpose of this study is to identify if there is reason to change the requirementsand recommendations for illumination in reception desks areas. This studyexamines how lighting in reception desks areas actually is and how the staff perceivesthe lighting.

    Hotels today usually have subdued environments that vary according to the typeof experience intended for their guests. Our interest has been to explore the receptiondesks area as an important and separate element within the hotel. We havecompared “Ljus och Rum” recommendations (Swedish Standards Institute [SIS],2011) with actual measured light levels for four reception desks areas and examinedhow the staff perceives how the lighting affects their performance of dailytasks.

    The methods we have used are light measurement, evenness calculations, visualanalysis and surveys. Lighting measurements were performed at four differenthotels in Gothenburg. The questionnaire was directed to the hotel staff in order toascertain their perception of the lighting in and around the reception’s desks area.In order to get an impression of and gain an overall understanding for the lighting,a visual analysis was done at each hotel.

    The majority of the staff considers the lighting sufficient to perform their duties.It is clear that the lighting is perceived differently in each of the four hotels, dependingon how each hotel is formed and how the lighting is designed.

    Abstract [en]

    The fitting room is an important part of a clothing store, it's often where the customer decides if they want to buy the garment or not. Therefore it is important that the customer can feel safe and comfortable when they are trying the clothing. A typical fitting room in Sweden today has only one bright spotlight that emits light either towards the face or from the ceiling above. This study explores possible lighting solutions that take into account the customer's experience in the fitting room.

    The study aim to increase understanding of the importance of a good light in fitting rooms, so that customers gets a nice experience and that clothes, body shape and facial features are shown in a natural way. The issue therefore included how lighting can affect the customer's perception of the clothing and how the perception of body shape, facial features and the clothes change in different lighting solutions.

    To answer these questions, observations were made in various clothing stores, followed by an experimental study divided into two parts. The first part was a practical part where trying different lighting directions were tested on a mannequin, which resulted in three selected lighting solutions. The second part was a full-scale study. 15 people evaluated a fitting room with three different lighting solutions.

    The result demonstrates the importance of natural shadows and contrasts on the face and body and that it is important to consider how light falls and avoid glare. This is done by well-placed or shielded fixtures and by using several different lighting directions. The lighting in fitting rooms should be adapted to the type of clothes and customer group.

    Effekten av färgskiftande vertikalljus i en arbetsmiljö2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The human being has developed during the daylight's dynamic variation of color temperature, direction and intensity. The variation positively affects our emotions and performance. The problem today is that we stay about 90% of the day indoors and the indoor lighting often lacks variation. With dynamic colored light, a changeable and stimulating environment can be created to improve future lighting environments. This study has examined how the user's motivation, well-being and concentration are affected by dynamic colored vertical lighting. An environment that quickly would become dull and understimulating, can instead get an interesting variation that makes it usable for a longer time with this lighting solution, without the motivation or well-being decreasing. The lighting solution is intended to be used during time periods as a boost.

    The experiment was divided into two treatments, one with static office lighting designed according to Swedish lighting standard and one where the dynamic colored vertical lighting was added to the regular office lighting. The treatments were performed in a simulated office environment at Jönköpings Tekniska Högskola. The treatment with dynamic colored vertical lighting slowly shifted in light colors through out the whole visible color spectrum on the room's vertical surfaces, to create a variation in the room. During the experiment, the subjects were required to answer questionnaires and performance tests to measure the influence of the dynamic colored light on the subjects well-being and cognitive performance.

    The results showed that the dynamic colored vertical light had a positive effect on motivation and well-being, but did not affect the concentration of the subjects. The positive effect that occurred was when the order of the treatments started with the dynamic colored vertical light and then ended with the regular working light. The conclusion is that dynamic colored vertical lighting can increase the motivation and well-being if it is applied correctly, without adversely affecting the concentration.

    The simulated office environment lacked windows, when scaling up any further research, a real office environment with windows would be preferable. Investigating further whether it is the actual variation of the colored light or the individual colors of the light that creates the effect on the users is also relevant, as this study did not specifically process that.

    Abstract [en]

    Abstract

    Purpose: This work presents Internet of Things or IoT in facility management; operation and maintenance. One of the many functions of IoT is making “smart” building components, which can communicate when they break and can be controlled from a distance. Today there are many articles on how you can use IoT in buildings but not as many on how you can use it in operation and maintenance of real estates. Therefore, the aim of this thesis is to investigate the possibilities of IoT in facility management; operation and maintenance work. This is investigated by the questions: (1) How can IoT be used in the facility management; operation andmaintenance work? (2) What are the savings in terms of workhours that can be made by using IoT in facility management; operation and maintenance work? (3) What is the attitude to IoT in the facility management industry?

    Method: The main strategy for this thesis is a case study in the facility section of the municipality in Jönköping. Approaches include interviews with IoT-consultants and employers at the facility section, document analysis of the workhours for different tasks of a operation technician and a literature study.

    Findings: The first question is answered by that IoT can be used for almost everything because of the huge amount of sensor types and that new ones are constantly in the making. You can also make unique IoT systems which contributes to the flexibility.The limits today are costs and finding value in the collected data.

    The second question is answered by that saving possibilities exists. Calculations are made based on attitudes from respondents and what they think are possible savings.This results in savings of about 13 000 workhours/year out of 30 000 workhours/year which equals 40 %.

    The third question is answered by that both employers at the facility section and IoT-consultants find IoT in facility management interesting. Of the different work-categories, it is interesting to mention that the most positive are the real estate managers and the maintenance engineers and the least positive are the operation technicians.

    Implications: Conclusions made are that the possibilities of IoT in facility management; operation and maintenance are many. In the future, a lot of savings of workhours can be made by using IoT. Since interest in IoT exists at the facility-section future studies should explore the costs of different IoT-systems. If the municipality of Jönköping chooses to implement IoT in their facilities they can become a role model for other facility managers.

    Limitations: The limitations in this work are the different costs of IoT-products and how the IoT-systems are built. The work tasks investigated include only supervision-tasks.

    Abstract [en]

    Through the different stages of life people have different requirements for their homes. The requirements changes depending on people’s life situation, lifestyleand age. Depending on where people are in life they live in different place, often in areas with other people who are in the same stage of life. In Sweden, this separation has always been noticeable, sometimes more than other. To minimizethis separation it’s required to take measures that make people from different stages of life come together. By offering people a home that suits them in an area with a high degree of differentiation, people from different stages are brought together. This refers to differentiation regarding apartments, houses, shops, workplaces and social service functions. Collecting apartments that suits different consumer groups in one single block leads to a higher degree of understanding among neighbors and make people from different generations come together. When the block is supplied with workplaces, shops, coffee shops and restaurants along with other social service functions a city life is created which resembles Sweden during the 1950’s. A society where once work, stores and social functions were important to have in your surrounding area. This is reflected in a richer urban life and a higher degree of movement in the neighborhood.

    Season influence on rapid thermal sensation assessment by young adults2019In: Engineering Reports, E-ISSN 2577-8196, Vol. 1, no 1, article id e12029Article in journal (Refereed)
    Abstract [en]

    Thermal comfort is one of the most important ergonomic aspects of building occupancy. In this research, laboratory experiments are performed in a climatic chamber and described in detail. Experiments are carried out under two scenarios: with two different college students cohorts and with five different but comparable experimental conditions in each cohort. Three hundred twenty‐two individual assessments under specific controlled thermal environment conditions are collected. The actual thermal sensation assessments obtained in the experiments are compared to the results obtained by a predicted mean vote (PMV) model. The correlation analysis shows that statistically significant differences are meaningful between the spring‐summer and the autumn‐winter experiments but not between genders. This paper discusses the plausible factors contributing to the different correlations experienced in the autumn‐winter and spring‐summer experiments. A correction factor between PMV according to Fanger's comfort equation and the actual thermal sensation values reported by the participants is also sought with a focus on the seasonal effects. The predicted results are in good agreement with the experimental results. This allows for further considerations about the influence of the season on the initial thermal sensations experienced by young adults.

    Socialt hållbar förbättring av bostadsmiljön för ett miljonprogramområde: Miljonprogrammets område Lextorp2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: At the beginning of the 20th century there was a large housing deficiency in Sweden. Over time the housing deficiency developed into a political issue and resulted in the million-program. One million homes would be built during 1965-1974. The million-program constitutes a large part of Sweden’s total housing stock. Many of these areas quickly became segregated and socio-economically weak. Municipalities are now faced with the decision to either phase out or develop the areas. The purpose is to investigate which measures can contribute to a better social sustainability and attractiveness in million-program areas. The aim of the study is to investigate which measures are effective in improving a sustainable housing environment in a millionprogram area. Method: The study has been conducted as a qualitative study in the form of interviews. Document analysis has been implemented where the information has contributed as a support but also as an eye-opener to find different solutions that are relevant in the case study. Observation in the area has been made to give the author a perception of the area. A literature study has been done to support the investigation and to receive information to create a foundation for the study. Findings: The main result of the analysis is that a key factor in achieving a sustainable housing environment is a major focus on social sustainability. The work with the social sustainability should be focused and deliberately with long-term perspectives. There are many ways of working with social sustainability, but a big part is to promote integration into socio-economically weak residential areas. The social issues form a basis for achieving a result and answering the questions set for the study. In order for the residents to have as pleasant living environment as possible, they should be given influence in various decisions made for the area. Implications: Proposed measures must be adapted to the specific conditions of each area. In order to contribute to an increased social sustainability it is important that the environments of the areas are well managed and completely clean. Social sustainability can also be improved through active work on social issues, which also contributes to increased attractiveness. The concept of social sustainability also includes urban design. A city that is well designed, safe and pleasant and has a good and functioning living environment is something desired. Limitations: The study is limited to only one million-program area since there is neither time nor resources available to map the problem on a larger scale. Own proposals are not presented, neither from an economic nor an architectural perspective, which could affect how the questions set for the study are answered. The focus is on whether planned measures are effective and whether these measures are sufficient to make an area attractive again.

    Purpose: Burnt alum shale is mining waste derived from combustion of the same rock. It exists in several places in Västra Götaland. Alum shale was previously used as filling but nowadays the use is limited thus the material is leaching heavy metals. The amount of waste normally put in landfills shall now be diminishing. Therefore the possibility to landfilling alum shale is limited. The purpose of this study is to increase the knowledge of how alum shale can be dealt with in an environmentally safe and economically beneficial way. The goal is to bring out suggestions for applications of use and ways of handling the excavations to contribute to a better environment and to achieve better financial conditions. By investigate what claims need to be achieved for the possibility of using Alum shale, useful areas of use and suitable management where brought forward. This study has been composed as a mean to get a bachelor degree in engineering, with the benefitial partner Skövde kommun.

    Method: Literature study, document analysis and interviews where used as research methods. Research on waste, alum shale and remediation techniques where studied in the literature study. In the document analysis, environmental study were analysed to retain knowledge of leachate. The interviews presented information of the authorities work with alum shale and experts’ suggestions of how alum shale can be used and handled.

    Findings: This study showed that there is other applications than landfills, and that there is methods to limit the leachate. If to be used, knowledge of the alum shale’s propensity of spreading due to stirring and relocation must be known. To inhibit leachate van be achieved by encapsulate the alum shale by waterproofing. This means that the alum shale can be used as a resource. Areas will be available for exploitation, it will not affect people in the surroundings, and the leachate to the groundwater will diminish.

    Implications: At minor sensitive land use, alum shale can be used as filling material, such as industrial areas and roads. This implicates waterproofing of the material. Asphalted surface, in combination of waterproofing the top surface and the vertical sides limits the leachate of metals considerably. The haul is often ruling the possibility to relocate the shale. If the alum shale, at disposal, could be used for filling purposes, the cost of purchasing new material, and outlet of new raw material does not need to burden the environment.

    Limitations: The alum shale studied is the one of Skövde County. The study should though be applicable to the whole of Västra Götaland. Not having the time to expand the interviews and include more people with research experience and expertise, is one of the limitations of this study. Also, carry out leachate tests could have contributed with more knowledge.

    Abstract [en]

    The paper is a thesis made by three students in the engineering program at Jönköping School of engineering. The thesis was overseen by the urban planning office and features data from Jönköping County.The purpose of the thesis is to improve future central districts by improvement of work methods. The aim of this thesis is, through an evaluation of process mapping, develop a model for systematical work methods with better experience feedback in the urban planning. The following three questions have been answered: How is the process mapping of the urban planning in Jönköping County built today and how did it affect the current district Kålgården? How can the urban planning of Jönköping improve with a more systematical work method with better experience feedback? How can critics elaborate the developed method to make it enough stable and in general applicable method to enforce on future districts?Literature studies and interviews were made to review the work methods of the office of urban planning as well as how their experience feedback works. Currently, systematical experience feedback and the communication between the departments and other operators is defective in Jönköping County.A case study was made because there is doubt about the success of Kålgården through the aspect of urban planning. The result of the case study shows that Kålgården was meant to be a link between two existing districts, which is correct. Studies of old local plans shows that there was a beneficial alternative for the landlords which was created by Jönköping County. The landlords took advantage of the technicality and prioritized their building processes for their own profit.The thesis contains elaborated proposals to improve established problems in the work methods. One of the solutions could be to arrange a steering group for every big project. The steering group would contain one member from different departments of the urban planning and one of the members will be given a main responsibility. This will shorten the information and decision paths. Another proposal is to adopt a town architect, for a more hierarchal point of view, with more direct decisions in the office of urban planning in Jönköping County.A process map has been created where the different proposals are included. It has been reviewed by key figures in Jönköping County and they think that it is stable enough to be applied in urban planning of other counties. There is an activity in the process map where the steering group evaluates the district after approved building permits and after a few years when the district has “grown in” to the city.

    Abstract

    This paper investigates the possibility of tenant governance in student housing. With the shortage of student homes in mind, the purpose of this work is to contribute to an increased production of student homes in Sweden, with the aim to clarify students' attitudes towards tenant governance. This should be answered through the questions that follow:

     

    1. What is the intent of tenant governance?

    2. To what extent can a student help with the maintenance of the residential building?

    3. How great is the interest in tenant governance among students? This paper is based on a literature study on the subject of tenant governance, interviews with property managers and a questionnaire study, to clarify students' attitudes towards tenant governance.

    The paper further investigates what tenant governance means and it is clarified that the concept is somewhat unclear but may be explained as maintenance work within the residential building that is carried out by the tenants, whom in return get their rent reduced. The concept of tenant governance depends on mutual cooperation between the landlord and the tenants. For tenant governance to work properly a landlord, who is willing to devolve his or hers responsibilities regarding the maintenance work to the tenants, is needed along with having tenants that are willing to assume that responsibility. In addition to the psychological aspects are laws that may hamper the development and expansion of tenant governance projects.

    In interviews suggested maintenance work, which could be performed by the students, was presented to property managers of student homes. The outcome was positive as the results show that the property managers could devolve all of the suggested work to the students, if compiled together.  Furthermore, a survey representing 232 people surveyed, consisting of equal parts of university students and high school students was carried out. A break down by gender, upbringing and type of living was made to see if any differences exist between the sample groups.

    The interviews showed that the property managers have a partly negative attitude towards the idea of tenant governance in student housing as their confidence in students' sense of responsibility is limited. According to the survey results, high school students tend to have a more positive attitude towards tenant governance than the university students. In general the high school students seem to have a greater interest in the questions asked. The most important difference between the sample groups was the fact that high school students tended to see influence and responsibility twice as important as the university students.

    Our proposal is to implement a test round with tenant governance in student housing. Moreover we suggest having only students who begin university directly after high school, as it is our belief that they are less influenced by today's housing market and have a greater interest in tenant governance than the university students.

    BIM use in the production process among medium sized contractors: A survey of Swedish medium sized contractors2016Conference paper (Refereed)
    Abstract [en]

    Building Information Modelling (BIM) is claimed to transform the AEC industry, whereas current research has argued that diffusion of BIM use proceeds at a slower rate than the optimistic predictions. However, governmental initiatives where public clients in countries like Finland, Singapore, United Kingdom and Sweden start to require a Building Information Model as a part of the project delivery, are supposed to increase the pace of diffusion of BIM use. Today, larger contractor firms use BIM to a varying extent. But BIM use in mid-sized contractor firms, with 50 – 500 employees, which successfully can compete with larger contractors on projects up to 50 million Euros, is relatively unknown. The aim of the paper is to explore the current use and perceived challenges and driving forces of BIM-implementation among mid-sized contractors. The data used in this study is collected through a survey send to chief executive officers, or their closest sub-ordinates, of mid-sized construction firms in Sweden. The survey is based on a technology-, organization-, environment framework that is used in information systems research in order to study the use of inter-organizational information systems. The total population of firms in the survey is 136. The preliminary results presented in this paper are based on 31 answers (30 percent response rate). 58 percent of the respondents said that they have been involved in a project where BIM has been used in some way. The most commonly used application is visualization. The highest obstacles perceived are that partners are not using BIM, there is no demand from clients, and there is no internal demand in the company. For the two last obstacles there were significant differences between users and non-users. The most common perceived driving forces were that BIM is a means for following the technical development and BIM can give the company competitive advantages. Moreover, the results indicate that the main driver behind BIM-implementation is mainly determined by an individual’s subjective positive or negative evaluation of BIM, rather than by external pressure from clients and partners, or by internal capacity and knowledge to use BIM.

    Abstract [en]

    This report describes from start to finish how a new design and extension of the Gengras student union center at the University of Hartford was done. The report will be using a project that was made by me and explains how the whole project was planned by contacting S/L/A/M Collaborative Inc. all the way until the final outcome was presented for a final jury. It explains the whole chain process one should use when designing a building such as different analysis, precedent studies, concept development and how to approach the design project. New technologies, the feature of access and flexibility are the main influence words in the design that is being used as an example. These words can be found and felt throughout the whole building both in the façade drawings and in the plan solutions. The result was a building that is more organic and flexible in its forms and spaces than current architecture is today. A sort of architecture that comes more and more in which will shape the society in the future. My building also keeps a sense of the old façade to create a transition between the new and the old. The old and the new cooperation prove that the innovative design does not destroy the old building; it only enhances it and prepares it for the future.

    Abstract [en]

    The new Eurocode standard requires adjustments in construction planning offices in the respect that staff must learn to use and comply with this standard. When designing connections in steel there is support available in terms of calculation methods and manuals, but there is still no extensive help on how to handle them with the Eurocode standard. Although the design process of connections is very important during the design of steel structures, there is currently a too slow process compared to what it could be. Therefore it would be good if an easier and faster way to design connections in accordance with the Eurocode standard were found.

    Interviews have shown that the design process had worked so that calculations were done by hand, by a designer according to BKR's rules, and then plotted in 3D by another designer who finally get their plans reviewed by a third person.

    Through case studies, of the standard connection BP1, an improved design process were sought after, compared to the one the interviews described. In the case studies BP1 was designed by hand and with the programs Autodesk Robot Structure Professional Analysis 2011 and was modeled with Tekla Structures 16.0, at all times in accordance with the Eurocode standard. Thanks to that a new and more effective design processes was found.

    Tekla and Robot are popular applications on the market and strong tools for engineers. The programs can be very helpful in the design of connections in steel. Robot is for advanced calculations and does it very well, but could be improved through a greater variety of connections. With Tekla the user can make exact drawings of the connection, but the settings of the measurements are complicated to understand.

    If the designer would start using the program Robot in the process, he would gain time, less information loss, a reduction in paper handling and a tidier information base to provide to the next step in the process. After that the designer quickly does drawings with high quality in Tekla and finally all the material would be available to the examiner who gets a better overview.

    It is not possible to transfer the connections from Robot to Tekla, but if it was possible, more time could be saved through a more efficient process

    Abstract [en]

    Purpose: Despite many previous articles and tests on the subject “analysis methods for concrete slabs on ground subjected to concentrated loading” there is still uncertainty on which analysis method to use and if the results correspond to real failure loads. The purpose of this study has been to evaluate and compare different analysis methods for slabs on ground subjected to concentrated loading.Method: Initially literature studies was performed where different analysis methods were studied. Three methods were chosen based on different aspects. It was found that A. Losbergs (1961) method was mainly used in Sweden while other countries in Europe used Meyerhofs (1962) method. Rao & Singhs (1986) method has a similar approach compared to Meyerhofs but ads two different types of failure modes. Two peer re-viewed articles were also chosen from which secondary data could be retrieved. The articles described tests where concrete slabs were loaded until failure. The test condi-tions were used to perform calculations with the three analysis methods. A comparison was made between the test results and the results from calculations.Findings: It is concluded that there are some differences between Losbergs, Meyerhofs and Rao & Singhs analysis methods. Largely the three methods require the same input, they differ in selection of analysis solution, but despite a degree of variation of the calculation results the overall picture for the different loading cases are quite unified. For central loading all analysis methods result in a capacity lower than the test values, varying from 56% to 93% of the failure load. Concerning edge and corner cases the spread of results is even wider. Calculations for the reinforced slab results in a capacity higher than the test values while calculations for the plain concrete slab results in a capacity considerably lower than the test values.Implications: The results in this study indicates that the three analysis methods are applicable for internal loading. The spread of the results makes it difficult to estimate the margin to the actual failure load, but the safety factors according to Eurocode 2 should provide a safe failure margin. Regarding edge and corner cases it is more diffi-cult to draw conclusions due to the large spread of results. Further research and testing is needed.Limitations: The study is limited to three analysis methods and the results from two articles where two different concrete slabs were tested. Inclusion of additional analysis methods and articles with test results would expand the generalizability of the study. However due to the limitations of the extent of the study and disposable time this was not possible.Keywords: Meyerhof, Rao & Singh, Losberg, concrete slab on ground, concrete slab on grade, point load, concentrated load.

    Abstract [en]

    The purpose of the study is to investigate how the lighting situation and the urbanenvironment affect various crime sites for violent crime in Jönköping. By analyzing lightingand the urban environment, a closer understanding is created as to whether the crime scenehas been illuminated, and how the urban space is experienced. The aim of the study is tolook at common denominators between the different crime sites and between the crimesites and experienced safe places.The study was conducted through observations at each crime scene. The crime sites wereanalyzed using the methods Percifal, “Branzell-analysis” and the “Alingsås method”. Theobservations occurred in the evening as close to the time of the actual crime as possible,so that the light conditions during the observations, should be equal to the light conditionswhen the crime occurred. All crime scenes had illumination, some places were lighter andother darker. The result of the study suggested that violent crimes, in particular, robberyare affected by the light conditions prevailing. No connections were found between assaultcases and the lighting or assault cases and the urban environment.

    Why do both your body and the shirt look different in the fitting room comparedto how they did in the store area? The continuing problem with lighting in fittingrooms is a fact. The lighting industry should have resolved this matter severalyears ago through the development process. This study investigates the problemfrom the viewpoint of three different stakeholders in order to presentrecommendations for lighting in fitting room. The following concerns are raised:1. What criteria’s defines good lighting in the fitting room?2. Seen from the store staff and customers perspective, what function does lightingin the fitting room have?3. Does the customers’ perception of themselves in the fitting room affect theirdecision to buy?Initially there was a pilot study with an observation of existing fitting rooms, andinterviews with lighting designers. After these, additional interviews with storemanager from five different stores in Jönköping were undertaken. Our two studymethods, survey and measuring of light, were used in these stores. The 70 surveyresponses were compared directly with the fitting rooms physical attributes thatwere documented by light measurements in the fitting rooms.The most important features with regard to lighting in fitting rooms are anaccurate visual color experience and a fair image of the body and face.Surprisingly, there are fitting rooms where lighting is deliberately weakened inorder to manipulate the customer to exit the fitting room. This will allow the storestaff to increase the chances of creating a relationship with the customer toinfluence purchasing decisions; an approach we would not like to recommend.Good lighting in fitting rooms is characterized by technical lighting choices thatharmonize with other features in the fitting room to create an unbiased image ofcolors, details and body shape. The lighting must also interact with all otherlighting in the store.In the survey we asked customers to what extent the four different factors listedabove influenced their decision of buying the tested garment. The factor that mostaffects the customer decision of purchase is the customer service (purchase doesoccur) and the price (purchase does not occur), thereafter the experience ofthemselves in the fitting rooms (for both). This result is congruent with well withlighting designers and store staff’s reasoning about what affects the customerspurchasing decision.Our conclusion is that the lighting in fitting rooms should give a fair picture ofbody, color and clothing. Recommendations for lighting in the fitting room wouldease the planning, but an optimal solution cannot account for the reality that allpeople have different sensitivity to light and diverse needs in the fitting rooms.The experience of the fitting room and specifically the lighting within can belinked to the decision of purchases.

    VVIS-stationer som ersättningsunderlag vid vinterväghållning2009Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This final year project is about the relationship between Vägverket, Swedish road authority, and the contractors involved in maintenance and service of roads. The contractor, in this case Svevia Vetlanda, is not satisfied with the system provided by Vägverket. The system is called RWIS and is to aid all the contractors around Sweden. RWIS is showing the weather conditions on the roads at approximately 770 different places. The system supports the contractors to decide if they should take action such as ploughing and ice dissolving of roads. Vägverket uses RWIS as an information system as well as basis for payment. The authority is very clear on that the contractors only should see RWIS as an aid. But they are themselves using it as their basis for compensation, this contradiction is the backbone of this project.The RWIS-stations are not always showing right values that are well known, butlately it has been showing consistently wrong values. This report holds evidence that the measuring stations are not always correct in measuring but they are then corrected by a system called MESAN. How this combination works and why this combination exists are some of the questions the contractors want answers on.The contractors are also wondering how Vägverket is managing and calibratingthe stations. When, how and how often is this done?During the interviews it occurred to me that they are going to replace the oldmodel of compensation with a new one. The differences between these are that the contractors are going to get paid for every kilometre ploughed instead as of now, getting paid if the systems encounter certain weather conditions.My conclusion is that the combination of RWIS and MESAN is reliable enoughto be trusted as a base for payment. But the problems with that the stations not showing the right conditions still remain. To prevent this from happening the contractor should demand a checklist from Vägverket that service andmaintenance is done.I agree with Vägverket that RWIS is not an accurate science, but at the same time use it as basis for payment is a big contradiction. Using MESAN is an upgrade but there is no other source that measures temperature. This means that the data from RWIS directly affect the payment.

    Minimera problem & konflikter i ledningssamordningen gällande kostnadsfördelning2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract

    Purpose: When the production of pipe transport occurs, the water supply system, television- and computer system (Opto), heating supplier and other pipe actors cooperates from the design phase to the production phase which entails a cost for each pipe actor. The current problem is the industry where there are no specific laws and rules regarding the cost allocations in the pipe coordination. It is known that the actors who skip some costs do not see it as a problem. Therefore, the investigations need to examine if and why the water supply organizations experience being responsible for the main costs in the design phase and if the other pipe actors have similar experiences. The other problem is management of pipe actors that join in at a later phase of the project. The goal of this report is to present suggestions of how to allocate the costs between each pipe actor, thus minimizing the risk for problem and conflicts in pipe coordination.

    Method: The used methods to answer the goal were; a qualitative research consisting of well-formulated questions in a semi-structured interview with relevant people. A quantitative research, constructed as a document analysis with calculations to account for costs in previous projects. Lastly, three fall studies were made to investigate the relation between water supply actors and other pipe actors.

    Findings: The final analyzed results and knowledge contribution shows how to allocate costs between actors as well as present the problems and conflicts that arise in pipe coordination. It is important to arrange pipe coordination at an early, as well as sustain and renewing the current data for pipe management as these are the main factors for misunderstanding.

    Implications: The final result of the report is a percentage of cost that mangers can take avenge of at pricing in projects. Also the possibilities to minimize the cost problems is development of a standard that everyone uses, explaining how pipes should locate in the trench. The project manager should become better at informing in earlier phases about pipe coordination. The pipe actors should update undocumented pipes so they are visible in a computer system.

    Limitations: The report opts to map problems in order to give suggestions on how to minimize complications in the pipe coordination between the water supply system, opto supplier and heating supplier in design and production phase. The report is relevant for every pipe actor and gives a better understanding to prevent problems and reduce costs. Interviews with engineers were conducted from different pipe actors and consult firms which gives a blanket results. Contact with more pipe actors for example electricity could have been consolidated with previous findings and thus make the conclusions more general.

    Keywords: Cost allocation, pipe actors, pipe coordination, problem and conflicts.

    STADEN - RUMMET - MÖTET: Temporär arkitektur i det offentliga rummet för ökad social hållbarhet2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: This study examines temporary architecture as a phenomenon. Temporary architecture is ephemeral structures with varying sizes and shapes that takes city’s public spaces in possession during short periods of time. As a phenomenon, temporary architecture is relatively new, but begins to appear more often in larger cities. Some research has been made on the subject in matter, but few researches describes the process behind and how social sustainability can be linked to temporary architecture. The research questions are: (1) How can temporary architecture contribute to increased social sustainability? (2) What characterizes the temporary architecture implementation process today?

    Method: The study is of descriptive nature and aims to create further understanding of temporary architecture. Data gathering are based on a qualitative approach through targeted interviews with relevant respondents from public and private sectors. A literature review is also conducted with the intention to clarify current research situation surrounding the study phenomenon.

    Findings:  Research question 1 indicates that temporary architecture affects social sustainability in several ways.  Four core values that each reinforce each other have been identified. These are community, participation, trust and movement. The temporary architecture encourages community and participation between people by providing short-term events to gather around in public space. New meetings enable trust, which leads to increased mobility. Movement resolves the social constraint principles in society and contributes to an increased community.

    Research question 2 indicates that the implementation processes for temporary architecture can differ widely depending on the context in which the temporary architecture is to be implemented. The question also indicates that there are several difficulties in the implementation process today. Significantly, in many cases the challenges outweighs the possibilities, why initiatives can be omitted.

    Implications: Short-term space-creating initiatives like temporary architecture enhance social qualities to urban life beyond the qualities usually obtained by traditional urban planning processes. The strength of temporary architecture lies within its formative and spatial flexibility as well as its ability to create increased participation and better access to the city’s content for people.

    Limitations: The study focuses on a social sustainability perspective only and excludes the economic and ecological perspective of the phenomena. The interview study is limited to only take planning and municipal perspective in concern. Business and user perspectives are therefore not taken into account.

    Digitalisering av bygglovsprocessen: Utifrån Sveriges kommuners perspektiv2019Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Idag finns det begränsat med forskning som studerar digitalisering av bygglovsprocessen, speciellt om man ser ur Sveriges kommuners perspektiv. Syftet med arbetet är således att sätta den aktör som i slutändan granskar och beviljar bygglov i fokus och låta de bli ett objekt för vidare studier. Målet med arbetet är att visa på möjligheter och hinder med att digitalisera dagens bygglovsprocess samt att bidra med ny information som Sveriges kommuner kan använda som underlag i en fortsatt utveckling av behandlingen av bygglovsansökningar.

    Metod: För att genomföra arbetet så att uppsatt mål nås har en litteraturstudie gjorts för att ligga till grund för genomförandet av intervjuer på olika kommuner. Efter genomförd litteraturstudie har 8 intervjuer genomförts på 7 av Sveriges 290 kommuner.

    Resultat: Det finns en stor variation i kommuners digitala utveckling i dagsläget. Samtliga kommuner ser stora möjligheter med en fortsatt och ökad digitalisering. Med hjälp av litteraturstudien och intervjuerna kunde många konkreta hinder identifieras, både genom erfarenheter och tankar om framtiden.

    Konsekvenser: Slutsatserna som kan dras efter genomförd litteraturstudie och genomförda intervjuer är att det behövs mer forskning på området. Man kan också slå fast att en digitaliserad bygglovsprocess är ett område med stor förbättringspotential och stora möjligheter. De rekommendationer som kan fungera som riktlinjer till olika kommuner är följande:

    ▪ Förankra investeringar hos ledning

    ▪ Förankra förändringar hos personal i ett tidigt skede

    ▪ Tillsätt någon ansvarig för den digitala verksamheten inom avdelningen

    ▪ Utföra mindre utredningar för att identifiera områden som kan förbättras med digitalisering

    ▪ Skynda långsamt, ta små kontinuerliga steg mot en mer digital process

    Begränsningar: Endast medelstora kommuner i Sverige undersöktes, förhoppningen var att kunna generalisera resultatet till mindre och större kommuner. Ingen annan aktör inom området undersöktes; entreprenören, privatpersonen eller samhället hade kunnat vara objekt för undersökningen om den varit mer omfattande. Även dokumentanalys hade kunnat adderas till de valda metoderna om arbetet varit mer omfattande.

    Nyckelord: digitalisering, bygglov, kommun

    Effektbelysning i trafikmiljö2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The thesis was conducted at Jönköping University in conjunction with the lighting design education in year 2017. The study aimed at investigating the traffic environment along the high way between Värnamo and Jönköping in order to map and get an idea of how the effect lighting can be used with colored light without creating a danger to traffic. The aim was to investigate whether the effect lights showed an impact on the driver's perception of the highway, and if the colors gave a difference in the experience or created distractions. The area was relevant to investigate as effect lighting are becoming more common after the technology has become more useful and economically justifiable. For that reason effect lighting with color are becoming more common, but are believed to have an impact on traffic that we are not aware of. The thesis questions were then formulated and investigated how effect lighting on objects affects drivers' experience in traffic. As well as if effect lighting of color and neutral light affect drivers’ experience of the road differently.The field study was conducted for three nights in March at a gas station related to the route that was investigated. Participants answered questions with semantic scales where they answered how they felt and experienced the road. Some of the participants were also randomly picked and asked if they could answer any following questions in the form of an interview.The road that was investigated had seven different effect lightings, witch three of them had colored light. The results showed that the lighting on the objects caught the attention of car drivers and affected the road drivers' experience of the road. The study also showed that the drivers were affected differently by the effect lights depending on whether the lighting was of colored or neutral light. The conclusions of the survey show how the drivers in this study experienced the road between Jönköping and Värnamo. To find out how effect lighting on objects generally affect road safety, more research is required.

    Utredning av begreppet sakkunnig, ur PBL-synpunkt2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: Throughout the 290 municipalities in Sweden, building inspectors work with applying the Planning and Building Act (PBL).  Within the legislation the term “expert” (in Swedish “sakkunnig”) is present, where the amendment in the law 2011 introduced a requirement for certification. The majority of all certification areas for experts that should have been introduced were left out and at present there is no possibility of applying the law as it was intended. The study therefore investigates how the building inspectors handle the absence of certification areas and persons without certifications.

    The aim of the study is to investigate how the municipalities building inspectors make sense of the interpretation of the term expert and how it is used in the application of the Planning and Building Act.

    Method: The study has been following a qualitative method in the form of interviews with nine building inspectors in six different municipalities. The interviews are confidential. The method also includes an initial literature study. The interview answers has been noted, generalized and compared by the method of comparison.

    Findings: In all the municipalities there is a mixture of certified experts and those who lack certification. All the building inspectors interpret the term expert as a certified person, but sometimes they deviate from using certified persons. The influence on building inspectors’ interpretation of the term expert is foremost the social work environment and the colleagues that one has. It can be stated that the handling is a reflection of the building inspectors’ sensemaking and that most municipalities handle the absence of certified persons by looking at the reasonableness in the situation.

    Implications: The problem that the study describes has come true through interviews with the building inspectors. PBL is not applied as it should be with certified experts, because there is a lack of regulations for more areas and a lack of certified persons in some municipalities. The building inspectors however do not experience a major problem with the handling because they cover the laws deficiencies and lack of certification areas by applying the older Planning and Building Act (ÄPBL), and making their own assessments. The inspectors handle it in a pragmatic and reasonable manner rather than legally correct.

    Limitations: The study is limited to investigate experts within the framework of PBL. Because certified persons in charge of inspections have a different role compared to other experts, they are not included in this study.

    Social hållbarhet – en tillgänglighetsinventering i Jönköping2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: This thesis investigates the accessibility in the existing housing stock in Jönköping. The inventory was carried out with the help of the handbook Accessibility in Existing Housing abbreviated as TIBB. 

    The aim is to investigate the extent of accessibility problems based on the selection in Jönköping city with TIBB, and to calculate costs for eliminating these problems. This provides a basis that contributes to improving social sustainability. To achieve the goal, the following questions were asked: (1) How many multi-family houses from the selection of 40, 50 and 60s in Jönköping, have problems with accessibility according to TIBB? (2) What is the occurrence of different types of accessibility problems in the surveyed apartment buildings? (3) What might the cost estimate be to meet the requirements of TIBB, with and without subsidization for an elevator?

    Method: The main method that was used for this thesis where a case-study with observation. A total of 15 real estate’s where investigated and gave data that was analyzed and gave results through data processing. A document analysis was made for cost estimate to use the same calculations to obtain generalizable figures, as well as compare costs. To give background to the problem a literature study has been accomplished which confirms that there are accessibility problems in the existing housing stock.

    Findings: The findings that shows that all investigated multifamily housing in the city of Jönköping have accessibility problems. Since they only reach the lowest level in TIBB. The most common accessibility problems for the investigated housing are that the lowest and highest step of stairs aren’t marked, no place for a walker outside and inside the entry, no elevator and the thresholds are higher than 15 mm. To address accessibility problems with the highest possible accessibility level for each property, the cost was estimated to amount to approximately SEK 20.0 million without subsidization when installing an elevator. The cost amounts to approximately SEK 10.4 million with subsidization when installing a elevator.

    Implications: The conclusions drawn are that the identified the accessibility problems based on the selection in Jönköping's city must be addressed to accommodate housing for the increasing proportion of elderly people in the future. Real estate companies may raise the rent by a maximum of SEK 450 per month if an elevator is installed. For real estate companies to be able to adapt their properties, which contributes to improved social sustainability, the proposal for subsidization when installing an elevator needs to go through, otherwise property companies will lose at a loss if they address accessibility problems.

    Limitations: Limitations in the thesis is for the year’s forties, fifties and sixties and only five multifamily houses from each decade has been inventoried. Costs relate to many different factors from a socio-economic perspective and will be limited to reasonable rent increases according to the property managers.

    Requirement Management in A Life-Cycle Perspective Using Asset Information Modeling Based on ISO 19650-1 And CoClass2019Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    Architecture, Engineering, Construction and Operation (AECO) industry is facing several challenges hindering practitioners from taking advantage of an integrated information requirement management process. Lack of researches concerning the practical point of view of classification systems supporting the asset lifecycle is recognized as a research gap which can enable practitioners to have better understanding over why they should utilize classification systems throughout the asset lifecycle. In this study, it has been tried to shed light on the fluctuations typically happen for different data values among the different project phases and address them by taking advantage of CoClass as the unifying means of building information throughout the lifecycle. For this purpose, the industry viewpoint towards the current status of asset information management and the existing obstacles, the new standard ISO 19650-1 principles as well as the experts’ ideas regarding CoClass capabilities and applicability were captured and analyzed. In this study, an element (a heating panel) in a meeting room belonging to the building of a company located in Stockholm was considered. The study revealed that CoClass is a rather new system and to fully support the whole asset lifecycle needs to be integrated into the AECO industry through practical use cases to reveal the capabilities, potentials and probable deficiencies.

    Abstract [en]

    The public interest in central living in today’s cities has led to an increasing effect of traffic noise pollution, and today 20% of the inhabitants in Sweden suffer from noise a level that exceeds the limits. At the same time the traffic keeps increasing, and recent researches shows that traffic noise pollution and several of today’s most common health issues are connected, for example, reduction of performance, sleeping issues and cardiovascular diseases. For this cause rules, guidelines and environmental goals has been developed, as well as software’s which calculates the levels of pollution, all this to investigate and improve the environment. The guidelines say that the average sound pressure level shouldn’t exceed 55 dBA over 24 hours of the façade, and the maximum level shouldn’t exceed 70 dBA. Today’s issue is that the guidelines isn’t legally binding and therefore they don’t have to be fully achieved which can led to confusion and unfair interpretations in the matter of a building can or cannot be built according to the limits of traffic noise pollution.

     

    The intensions of this report are to improve the urban environment regarding traffic noise pollution and to increase the understanding and knowledge how this issue affects urban areas. The report will also investigate and compare two different calculation methods for traffic noise pollution, the Nordic propagation method and the Nord 2000.

     

    On this basis a literature survey has been done regarding the noise pollution issues in our cities with its rules, guidelines, objective goals, measures and the two different calculation methods. Investigations of different shapes of a building has been done in combination with the software for calculation of road traffic noise Soundplan, and a case study of a site which is located in the centre of Jönköping. The workflow has been reversed from the “normal”, were the building were designed after the limits of the noise levels were investigated. This resulted in a residential proposal which is optimized from a traffic noise point of view, and uses its own body as a shield. The condoles are directed away from the source of noise and the parking space are placed towards the roads. The final result has been analysed with both of the calculation methods, were a slightly differentiation between the methods can be seen. This is causes by the way the calculation methods deal with information and the differentiation in the calculation methods.

     

    The conclusions from this report are that the traffic noise pollution is one of our major health issues which still are increasing. The main problem in this is that there’s several unmeasurable parameters which influences the way an individual experiences the sound environment, which contributes to the difficulty to establish a proper regulations and standards. Regarding the calculation methods there is issues to use Nord 2000, because the method requires large amounts of information which can be difficult to access. At the same time the Nordic propagation method can show incorrectly results because it hasn’t the same ability to adapt to the specific conditions at each location.

    Utformning av sidoområden med hänsyn till vägens livscykelkostnad2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:

    1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.

    By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise. This breakpoint is highly dependent on several factors such as the price of land, the presence of bedrock in the construction process and if the ballast material needs to be treated. A flatter slope causes an increase in both the volume of material and the area of land that needs to be obtained, while a steep slope with a barrier may result in higher costs to society due to fatal collisions with the barrier and higher operating and maintenance costs.

    Hur dagsljusinsläppet påverkar upplevelsen av ett rum2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The background to this report is based on how architectural art through times been treating daylight with greatest precision to take advantage of its good quality, and how the technical revolution with artificial lighting affects our way of working with daylighting today.

    The purpose of the study is to contribute to the knowledge how the daylight opening affects the perception of a room. The aim is to clarify how proportions and placement affects how the incident light occurs in the room and how that affects on how the room is perceived. The study is meant to be used by lighting planners, and in terms of pleasantness, be able to create the best possible daylight environment.

    The following questions were formulated:

    • How do the positions of daylight openings affect the perception of a room?

    • How do the proportions of daylight openings affect the perception of a room?

    • How much light enters the room as a result of proportions and placements of daylight openings?

      The investigation began with a pre-experiment where window configurations were observed in a scale model and then tested in a full-scale experiment. During the experiment surveys were made in a sample group of twenty people who had to answer questions about spatial experience, followed by lighting calculations that were made in all four experimental settings.

      The result shows that large daylight openings provide a high level of light but contribute to low spatiality, deterioration of contrasts and increased risk of glare. Smaller, low-set horizontal daylight openings tend to give the same levels of light but create a better sense of space and reduce glare.

      With high positioned horizontal daylight openings the result shows a deterioration of spatial experience and the room is perceived closed and stuffy.

      A vertical daylight opening is shown to make the room feel small and high, and the level of light is low, the contrast ratio and the completeness experienced worsening.

      The result shows that the window surface area affects the experience but is not essential how the daylight openings affect the perception of the room, it looks like the matter of placement have greatest impact on the room experience. It also shows that the darker rooms have higher spatiality than the lighter ones. The study shows that the test group liked the room with low-set horizontal daylight openings better.

    Förbättrad analysmetod av bullerimmission från vindkraftverk2015Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The expansion of wind power in Sweden has increased rapidly and will continue to do so for the foreseeable future. More and more inhabitants will then be exposed to wind turbine noise which in turn leads to a greater challenge in finding suitable locations for the continuing expansion. The often used models for calculation of wind turbine noise, SEPA and Nord2000, has been criticized for not resulting in an estimated value that matches the real noise level.

    The purpose of this final report is twofold:

    -          Increasing knowledge of the flaws in present calculation models by presenting the critique that has been lifted in recent years as well as presenting suggestions for improvement.

    -          Performing an experiment that examines the possibility of analyzing recordings of immission levels with an algorithm in order to obtain a result that better coincides with the noise experience of inhabitants.

    Method: Literature analysis, hypothesis construction and an experiment

    Findings: The calculation models SEPA and Nord2000 lacks in accuracy because they do not take several of the weather effects that can influence the spreading and strength of wind turbine noise in consideration. The usage of immission recordings are, as of now, substandard due to the large amount of background noise becoming a part of the measured result. By using a computer algorithm that can find wind turbine noise in a recording and extracting only those parts, a recording that better represents situations where extreme wind turbine noise occurs can be produced.

    Implications: To limit the underestimating of estimated noise immission values, newly formulated limits can be presented. An algorithm that extracts wind turbine noise from a recording has good potential to give more accurate measuring results.

    Limitations: This final report does not deal with the handling of measuring equipment nor sea based wind turbines.

    The literature analysis consists of comparing official documents, made by the Swedish Environment Protection Agency, which are used as basis for building permits of wind turbines, with reports and studies that questions the feasibility behind those documents. Based on this, hypotheses are formed that becomes the foundation for the algorithm’s workflow and test environment.

    Abstract [sv]

    I dagens samhälle diskuteras det hur vi ska kunna bli mer miljövänliga, minskakoldioxidutsläpp och annan miljöförstöring som belastar vårt samhälle. För attSverige ska kunna minska utsläppen krävs det bland annat att man ser över ochändrar landets trafiksystem. Det gäller för kommunerna att planera för en minskadandel bilister och öka andelen cyklister. Detta är speciellt viktigt i städers centraladelar där bilismen oftast är det främsta färdmedlet, trots korta resesträckor. Det ärdärför av stort intresse att studera hur cykelvägar bör utformas för att få så mångasom möjligt ska välja cykeln i första hand. En supercykelväg dvs. en cykelväg somhar företräde i trafiknätet och som är utformad för att möjliggöra högre hastigheter,kan innebära en ökad andel cykelresor i städerna.Syftet med examensarbetet har varit att öka cykelns attraktivitet som färdmedel.Målet med examensarbetet har varit att belysa viktiga faktorer vid utformningenav supercykelvägar samt visa på olika sträckdragningsmöjligheter för supercykelvägari svenska städer utifrån målpunkter.

    I arbetet har tre frågeställningar behandlats:

    • Vilka viktiga målpunkter finns det i svenska städer och hur görs de mer attraktivaför cyklister?
    • Vilka faktorer är viktiga vid utformning av supercykelvägar?
    • Hur kan man anlägga en supercykelväg i en medelstor svensk stad?

    Metoder som användes för att besvara frågeställningarna är litteraturstudier, fallstudiesamt enklare skissarbete.

    Resultatet visar att målpunkters attraktivitet till stor del beror på hur väl utformatcykelvägnätet är i helhet. Det krävs korta förbindelser, trygga och säkra vägar medtydliga och kontinuerliga sträckdragningar. Vid målpunkter krävs det att cykelparkeringarär väl tilltagna och utformade för att öka tryggheten och säkerheten förcyklister. Detta är extra viktigt vid större målpunkter i staden.

    Vid utformningen av supercykelvägar bör man ta hänsyn till de fyra faktorernaframkomlighet, säkerhet, orienterbarhet samt underhåll. Det är viktigt att satsa likamycket på alla faktorer för att totalt sett få en bra utformning och en hög användningav supercykelvägen.

    Supercykelvägar ska tillföra en genhet för cyklister, oavsett om de ska färdas in tillcentrum, ut till omkringliggande områden eller runt staden. För att få bästa möjligagenomslagskraft av en supercykelväg i staden bör en kombination av centrumorienteradoch cirkulär sträckdragning vara den bästa lösningen. På så vis kancyklisten färdas snabbt och smidigt med högsta prioritet i hela staden.
