    Dynamic lighting systems in psychogeriatric care facilities in the Netherlands: A quantitative and qualitative analysis of stakeholders’ responses and applied technology2015In: Indoor + Built Environment, ISSN 1420-326X, E-ISSN 1423-0070, Vol. 24, no 5, p. 617-630Article in journal (Refereed)
    Abstract [en]

    Long-term care facilities are currently installing dynamic lighting systems with the aim to improve the well-being and behaviour of residents with dementia. The aim of this study was to investigate the implementation of dynamic lighting systems from the perspective of stakeholders and the performance of the technology. Therefore, a questionnaire survey was conducted with the management and care professionals of six care facilities. Moreover, light measurements were conducted in order to describe the exposure of residents to lighting. The results showed that the main reason for purchasing dynamic lighting systems lied in the assumption that the well-being and day/night rhythmicity of residents could be improved. The majority of care professionals were not aware of the reasons why dynamic lighting systems were installed. Despite positive subjective ratings of the dynamic lighting systems, no data were collected by the organizations to evaluate the effectiveness of the lighting. Although the care professionals stated that they did not see any large positive effects of the dynamic lighting systems on the residents and their own work situation, the majority appreciated the dynamic lighting systems more than the old situation. The light values measured in the care facilities did not exceed the minimum threshold values reported in the literature. Therefore, it seems illogical that the dynamic lighting systems installed in the researched care facilities will have any positive health effects.

    Performance of personally worn dosimeters to study non-image forming effects of light: Assessment methods2017In: Building and Environment, ISSN 0360-1323, E-ISSN 1873-684X, Vol. 117, p. 60-72Article in journal (Refereed)
    Abstract [en]

    When determining the effects of light on human beings, it is essential to correctly measure the effects, and to correctly measure the adequate properties of light. Therefore, it is important to know what is being measured and know the quality of the measurement devices. This paper describes simple methods for identifying three quality indices; the directional response index, the linearity index and the temperature index. These indices are also checked for several commonly used portable light measurement devices. The results stresses what was already assumed, the quality and the outcome of these devices under different circumstances were very different. Also, the location were these devices are normally worn has an impact on the results. The deviation range between worn vertically at eye level and the wrist is between 11% (outdoor) to 27% (indoor). The smallest deviation, both in indoor and outdoor, was found when the device was placed on the sides of the eye (7%).

    Implementering av det biofila fenomen i utformningen av skolbyggnader2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Today, humanity is trying to develop in all areas of life, so that we can reach a cleaner, more modern, and more sustainable world. This study highlights the importance of architecture to improve areas of life. This report talks about a type of architectural design. It is called biophilic design which means to combine nature with buildings. This study is about biophilic design in school buildings.

    Method: To perform the survey, three different methods were chosen. The first method was a questionnaire sent to college students and high school students, the second method was interviews conducted with knowledgeable architects who have extensive experience in the subject of biophilic design and the last method was literature studies.

    Results: All data collected from the questionnaire, the interviews and literature studies are summarized as follows:Most college students and high school students think that when you are closer to nature it makes you feel better and that it would help improve the teaching process. Architects who were interviewed thought that biophilic design in school buildings has both advantages and disadvantages, but in general they support the idea of using and spreading the idea more in Sweden.

    Analysis: The analyzed data have shown that it is possible to implement biophilic design on the inside and outside of a school building in unusual ways. But many problems will arise, and one must have the will to continue to maintain these materials. It turned out that having these natural elements in school will contribute to a positive effect on the learning environment and the students themselves. For example, as a more creative, calm, and de-stressing environment. Having a green roof seems like an innovative idea but it requires a lot of maintenance.

    Discussion: This study focuses on how to implement biophilic design in a school building and what impact it has on the learning environment. The study addressed what is required to integrate the qualities of nature in the right way to maximize its effects. Studying biophilic design, nature and how it affects people and architecture and its impact on people has helped to lead to a clear result.

    Non-image-forming effects of light: Implications for the design of living and working environments2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Seasonal variation in mood and subjective well-being are common at geographical locations further away from the equator. The 24-h light-dark cycle is the main time cue for synchronizing the human circadian clock to the external day and night.

    Nowadays, people spend more of their waking day indoors, with less exposure to the natural daylight cycle, relying on artificial lighting which differs to daylight in a number of aspects, including intensity, spectral composition and light exposure pattern.

    In parallel with the technology development that has been mainly driven by energy-saving reasons, it is important to investigate the non-image-forming effects of different properties of the daily and seasonal light exposure.

    The overall aim of the thesis was to identify characteristics of the daily light exposure that are important to support physiological and psychological needs of humans. To achieve this objective a number of research questions were posed concerning daily and seasonal light exposure, seasonal variation in physiological processes and psychological parameters, and evaluation of light exposure with respect to non-image-forming effects. The research questions were investigated in a longitudinal research design with measurements conducted each month during the year at a high latitude with large seasonal variation in day lengths.

    Self-report diaries and instruments for ambulatory- and static measurements were used to examine daily and seasonal light exposure in the working and living environments and for investigating the relationship between different parameters that can be used for evaluating light exposure according to non-image-forming effects of light. Seasonal variation in daily light exposure and regarding the pattern of light exposure was observed. Also, the results indicate a seasonal variation concerning the quality (i.e. spectral composition of the visible radiation) of the exposing light.

    Two biological markers, melatonin and cortisol, were used for investigating seasonal variation in physiological processes relating to the circadian clock. The results showed higher morning melatonin concentrations and peak level of melatonin during the winter although no seasonal change was observed concerning the phase position of the melatonin rhythm.

    Seasonal differences in mood and sleep-activity were studied by means of selfreport diaries and questionnaires. Seasonal variations were observed for both parameters. The results showed higher ratings of mood in the summer, particularly 6 in the evening, and a relationship between bedtime and evening light exposure and photoperiod length. Furthermore, longer sleep times was observed in the winter.

    Appraisal of lighting conditions in the offices during the year was rated by the use of a questionnaire. The results showed some seasonal differences concerning the perceived qualities of the light and some associations between characteristics of the lit environments and positive affect were found.

    Two methods, static- and ambulatory measurements, were used for recording lighting conditions in the working environments. Taken together, the results showed weak associations between the two methods.

    Research have demonstrated an increased need for taking non-image-forming effects into consideration when designing working and living environments, especially at geographical locations with large variations in day length where people are exposed to much of the daily light exposure at the workplace. Laboratory research has provided a good understanding of the basic concepts. However, more field research is needed. Also, current research has demonstrated that new methods of measuring and evaluating lighting conditions are needed.

    Annual variation in daily light exposure and circadian change of melatonin and cortisol concentrations at a northern latitude with large seasonal differences in photoperiod length2016In: Journal of Physiological Anthropology, ISSN 1880-6791, E-ISSN 1880-6805, Vol. 36, no 1Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Seasonal variations in physiology and behavior have frequently been reported. Light is the major zeitgeber for synchronizing internal circadian rhythms with the external solar day. Non-image forming effects of light radiation, for example, phase resetting of the circadian rhythms, melatonin suppression, and acute alerting effects, depend on several characteristics of the light exposure including intensity, timing and duration, spectral composition and previous light exposure, or light history. The aim of the present study was to report on the natural pattern of diurnal and seasonal light exposure and to examine seasonal variations in the circadian change of melatonin and cortisol concentrations for a group of Swedish office workers.

    METHODS: Fifteen subjects participated in a field study that was carried out in the south of Sweden. Ambulatory equipment was used for monthly measurements of the daily exposure to light radiation across the year. The measurements included illuminance and irradiance. The subjects collected saliva samples every 4 h during 1 day of the monthly measuring period.

    RESULTS: The results showed that there were large seasonal differences in daily amount of light exposure across the year. Seasonal differences were observed during the time periods 04:00-08:00, 08:00-12:00, 12:00-16:00, 16:00-20:00, and 20:00-24:00. Moreover, there were seasonal differences regarding the exposure pattern. The subjects were to a larger extent exposed to light in the afternoon/evening in the summer. During the winter, spring, and autumn, the subjects received much of the daily light exposure in the morning and early afternoon. Regarding melatonin, a seasonal variation was observed with a larger peak level during the winter and higher levels in the morning at 07:00.

    CONCLUSIONS: This study adds to the results from other naturalistic studies by reporting on the diurnal and seasonal light exposure patterns for a group living at a northern latitude of 56° N, with large annual variations in photoperiod length. It seems to be seasonal variation in the lighting conditions, both concerning intensities as well as regarding the pattern of the light exposure to which people living at high latitudes are exposed which may result in seasonal variation in the circadian profile of melatonin.

    Comparison of Static and Ambulatory Measurements of Illuminance and Spectral Composition That Can Be Used for Assessing Light Exposure in Real Working Environments2019In: LEUKOS The Journal of the Illuminating Engineering Society of North America, ISSN 1550-2724, E-ISSN 1550-2716, Vol. 15, no 2-3, p. 181-194Article in journal (Refereed)
    Abstract [en]

    Reliable measurements are of utmost importance when investigating the relationship between light and human reactions. The aim of the present study was to compare two methods for measuring light exposure in real working environments. Ambulatory recordings of illuminance and irradiance were compared with static field measurements of horizontal illuminance at the normal working position, average horizontal illuminance in the room, vertical illuminance at the position of the eye in the normal angle of gaze, and spectral composition of the light radiation at the normal working position and at the position of the eye in the normal angle of gaze. The ambulatory measurements were carried out during a 3-day experimental period and were repeated monthly throughout the year. The static field measurements in the subjects’ offices were conducted five times during the year, in the morning and afternoon during one day. The relationship between the illuminances and irradiances measured with the portable instruments and the static measurements was statistically analyzed. Results from the analyses revealed that more than one third of the static measurements of vertical illuminances recorded were below 200 lx, and only 7% of the measurements exceeded 1000 lx. Measurements of the spectral composition of the light radiation in the rooms suggested that the light, although at a fairly low intensity, included relatively much radiation that can have a non-image forming effect. Furthermore, only a small number of significant correlations between the ambulatory and static measurements were found. Results from the t-tests showed that there were no differences between ambulatory measurements, and static measurements of horizontal illuminance at the normal position, average illuminance in the room and vertical illuminance at the position of the eye during three, five, and seven of the 10 measurements, respectively. There is a need to define appropriate parameters in order to describe the quality of a lit environment with respect to the non-image-forming effects of light radiation.

    Seasonal variation in bright daylight exposure, mood and behavior among a group of office workers in Sweden2018In: Journal of Circadian Rhythms, ISSN 1740-3391, E-ISSN 1740-3391, Vol. 16, article id 2Article in journal (Refereed)
    Abstract [en]

    The purpose of the study was to investigate seasonal variation in mood and behavior among a group of office workers in Sweden (56°N). Thirty subjects participated in this longitudinal study. The subjects kept a weekly log that included questionnaires for ratings of psychological wellbeing and daily sleep-activity diaries where they also noted time spent outdoors. The lighting conditions in the offices were subjectively evaluated during one day, five times over the year. There was a seasonal variation in positive affect and in sleep-activity behavior. Across the year, there was a large variation in the total time spent outdoors in daylight. The subjects reported seasonal variation concerning the pleasantness, variation and strength of the light in the offices and regarding the visibility in the rooms. Finally, the subjects spent most of their time indoors, relying on artificial lighting, which demonstrates the importance of the lighting quality in indoor environments.

    Efficient daylighting approach by means of light-shelve device adequate for habitat program in Aarhus City2014In: International Journal of Smart Grid and Clean Energy, ISSN 2315-4462, Vol. 3, no 4, p. 441-453Article in journal (Refereed)
    Abstract [en]

    The concepts of light shelves consist of windows that have face towards the sun, which receive a vast quantity of energy that could be used for healthy day lighting. This paper debates a main assessment, investigates the optimization of daylight requirement by means of light shelves system. An experimental test was carried out assessing the measurements and lighting simulations of a model of a building in order to elucidate the characteristics of indoor lighting. Light shelf is an architectural element that permits daylight to enter deep into a building. It constitutes an optimal solution for an incorrect building orientation and less sunny days. The essential objective of this study is to highlight the vital role of light shelves in residential buildings in northern Europa where the requirement is to improve the daylight in the interior functional spaces. The main objects of this paper are to investigate the effect of daylight in the interior functional spaces using light shelves, the effect of natural light diffusion in interior space in the period of low daylight season, and glare effect in this field. This paper investigates a procedure for analysing the daylight performance using software habitat function program. The experiment focuses on the difference between light shelves placed in the interior, vs. on the exterior.

    Biophilic and bioclimatic architecture: Analytical therapy for the next generation of passive sustainable architecture2011Book (Refereed)
    Abstract [en]

    The concept of biophilic and bioclimatic architecture represents one of the most promising ideas in sustainable building. Together with its consideration of ecologically harmless materials and use of renewable energy sources, it brings an enormous quality increase in planning and workmanship, as well as an improvement in inhabitants' comfort. This valuable concept merits a dedicated discussion.

    Biophilic and Bioclimatic Architecture outlines a new movement that aims to create environmentally-friendly, energy-efficient buildings and developments by effectively managing natural resources. The book has three parts:

    • Part I focuses on the impact of human needs on the creation process and assesses the concept of value in architectural hypotheses.
    • Part II opens the way to a new understanding of biophilic architecture as a response to destructive human activities and also considers the side effects of using natural resources.
    • Part III shows the significant benefits of making the connection between climate and comfort that can be achieved through bioclimatic architecture.

    Biophilic and Bioclimatic Architecture will enable architects, engineers and other specialists to develop innovative, sustainable architectural designs.

    A Research on the Biophilic Concept upon School's Design from Hot Climate: A Case Study from Iraq2022In: Advances in Materials Science and Engineering, ISSN 1687-8434, E-ISSN 1687-8442, article id 7994999Article in journal (Refereed)
    Abstract [en]

    In recent years, there have been solid global trends and severe attempts by ministries of education in the world to improve the reality of educational institutions and schools through the design and construction of schools and educational systems that meet the requirements of the age by applying the concepts of sustainable and effective systems to the new generation. They called for a promising future and hence the need to activate the applications of the biophilic schools. The theme of the biophilic schools is closely related to the concept of sustainable environmental structures that deal with the surrounding natural environment with intimacy, which is one of the most important new methods of design and construction at present, where ecological challenges are powerfully evoked in the making of their design decisions. Biophilic schools are an essential part of a new concept that wants to design revolutionary educational systems with new economic outputs that are valuable but do not depart from the idea of sustainable schools in general. It represents an expression given to schools designed to be environmentally sensitive and healthy for their occupants and educational systems based on experience, humanity, and attraction. Indeed, many architects have begun to explore and develop new architectural designs linked with the concepts of biophilic schools. Through the researchers' awareness of the negative circumstance experienced by school buildings in Iraq and by investing in the recommendations of an applied field research, it was reached to crystallize the research problem represented in the obstacles that schools suffer from, which calls for the search for developmental solutions for an efficient educational environment, and in order to reach this goal, by informing researchers about new global experiences in this field, the research presented its hypothesis in choosing the model of biophilic schools that exist in many countries in the world, because of what it can provide from successful and fruitful educational and urban components. The researchers reached many conclusions and recommendations aimed at applying the research hypothesis and achieving its goals.

    Bioclimatic interpretation over vernacular houses from Historical city Basrah2006In: PLEA 2006 - 23rd International Conference on Passive and Low Energy Architecture, Conference Proceedings, 2006, p. I87-I90Conference paper (Refereed)
    Abstract [en]

    Basrah's climate is hot, dry summer, mild to cold winter, and a pleasant spring and fall. The old builders from this region putted a big effort to create passive bioclimatic houses that corresponds the negative effects Basrah's macroclimate. The courtyard is the central and dominant space in the house plan with a direct access to the living spaces. Houses from the city are compact with interior courtyard; the streets are sinuous and pass through houses volumes. The shady interior courtyard has the effect that the rooms do not communicate directly with the overheated air outside, but through intermediate buffer spaces. In the mean time between courtyard and street at least a wall or a building is always interposed. The House plan had an endomorphic form, (open tree form). The volumes were concept to create shadow which helps to move the air by natural movement to the deep superior side, that can be achieve through special holes. The architectural elements are strongly decorated, reproducing special typologies and traditional houses. Open spaces, covered by large roofs, are interesting due to the mix of diffuse light and shade that are an essential aesthetic factor in these buildings.

    Abstract [en]

    Introductory paragraph: Human settlements are the result of the dynamic adaptation of the human community operating in a given territory in the conditions of social, economic and historical relations. The areas on which human settlements are located are distinguished by the components of the physical-geographic structure, by the diversity and by the potential natural conditions, as well as by the economic and social factors in which the human settlements appear and develop [1]. Human settlements represent the totality of human communities, villages and towns, regardless of their position, size and functions. Human settlement can be considered a geographic landscape integrated with the natural and social conditions necessary for the existence of housing, work and equipment (power supply, water, transport, communications, sanitation, etc.). Human settlement is a body of land known to be a regular form of property with a hearth on which communal and territorial attributes develop [2]. The term “locality” defines a human, rural or urban settlement, delimited according to the number of inhabitants, the nature of the built-up area, the degree of the social endowment, the technical-public amenities, the function, etc. Hence, human settlements or human habitat refers to some components such as population, construction, markets, streets, industrial platforms, recreation and recreation areas. Human settlements support the unity of natural, social, material, spiritual, cultural and organizational factors, including housing, labor, energy supply, communications, water, sanitation, services, social security, administration systems, cultural facilities, recreation, etc. [1]. The village is the oldest form of human habitation that presents ethnographic, historical, economic, social or urban characteristics. A village is a group of houses and people who are leaving their means of existence of a determined social space.

    Abstract [en]

    Introductory paragraph: One of the most critical phenomena in the real estate sector to reduce the environmental impact and climate change is sustainable houses. “All nature strives for self-preservation,” said the philosopher Cicero. And residents of megalopolises, too, increasingly began to think about the future of cities and how to improve the environmental background around their place of residence. One of the most innovative urban developments in the twenty-first century is the design of buildings and entire neighborhoods in sustainable architecture. Ebenezer Howard, whose 1902 book was entitled Garden City of Tomorrow and whose political and social agenda has recently made a comeback [1]. The idea of sustainability involves enhancing the quality of life, thus allowing people to live in a healthy environment with improved social, economic, and environmental conditions [2]. In addition, this type of building facilitates the most respected lifestyle with the territory, reducing the ecological footprint.

    Abstract [en]

    The term vernacular architecture is widely accepted by architects and derives from the Latin “VERNACULUS”, which means “domestic, native, indigenous”, local. So vernacular architecture designates the entire culture built from a particular place. In modern housing design, the inheritance and development of traditional architectural culture is reflected in the inheritance of classic architectural forms and craftsmanship and the rational application of traditional building systems. With the progress of social civilization and the improvement of technological level, various innovative building systems emerge in an endless stream and are widely used in modern housing design. In today’s rapid social and economic development, housing changes are coming quickly, sometimes even seeming a bit rough. At present, more attention is paid to the construction of new residential areas. As far as the field of urban architecture is concerned, the human settlement environment can be understood explicitly as people’s living and living environment. Today architects need to design a settlement that balances all social functions between meeting current needs and future development, designing energy and material-saving buildings, so that it is in harmony with the environment, and is conducive to the physical and mental health of the human body. In other words, the planning process requires attention to human behavior, psychology, emotions, and interpersonal relationships.

    Natural Lighting Efficiency By Means of Sun- Skylight-Tubes2014In: International Journal of Engineering and Advanced Technology, E-ISSN 2249-8958, Vol. 3, no 3, p. 16-20Article in journal (Refereed)
    Abstract [en]

    The notion of comfort a luminous ambience refers to the distribution of luminance and chromatic ties on the interior envelope of a space that is one of different fields of vision for a subject within an ambience. Luminance and chromatic ties are at present not often studied as far as comfort in buildings is concerned. Sun lighting and bioclimatic concept is inseparable considerations when designing a building because of the historical and practical significance of natural lighting in architecture. Sunlight is as old as architecture itself. Human life gets sufficient sunlight, in fact, we use more of 90 % of our day indoor, for this reason, specialists are now seeing how architecture can ameliorate the indoor-outdoor links. At present, by biological and technological investigation the trend is to search backwards towards the previous philosophies and advantages of more indoor / outdoor relationship. Plus homeowners who want to have healthy home environments might want to renew the most relevant facts of technology and biology.

    Abstract [en]

    he creativity of modern architects and urban planners, engineers and technologists working in various fields of design and construction activities as well as the creation and production of new materials, structures and technologies are inextricably linked with general trends in socio-economic development. It can effectively support the importance of architecture as a product in the sense of social response. The marketing activities are those activities that suffer adjustments due to the continuous changes in the users' needs to their behavior. In another hand, the subject of sustainable architecture and marketing became an important issue within design and construction process, where the application of the sustainable concept in design and execution process is rescuable, and it is not clear, therefore a clear reading of the building production by a clear strategy put sustainable architecture in a right way towards salability and it will be clear. The aim of this study is to create an evident comprehension, of the correlation between the phenomenon of marketing, supported by the concept of quality in sustainable architecture, and what it represents for the building users today. The method in this article takes two kinds of approach, the first is a literature study the other one is a semi-structured quality method, where an involved person has to create a hierarchy of priorities of many factors, related to the sustainable architecture factors. The study offers a clear reading of the most required factors of building users for getting a high-quality sustainable architecture.

    Abstract [en]

    Sustainable housing is generally used to describe housing that is environmentally friendly and resource-efficient over the lifetime of the building. Homes are designed to have the least possible negative impact on the environment. This means energy efficiency, avoiding environmental toxins, and responsibly using materials and resources while having positive physical and psychological effects on inhabitants. This book presents a comprehensive overview of sustainable housing, starting from legislation and ending with the design and configuration of homes.

    Urban biophilic theories upon reconstructions process for Basrah City in Iraq2014In: 30th International PLEA Conference: Sustainable Habitat for Developing Societies: Choosing the Way Forward - Proceedings, CEPT University Press , 2014, p. 9-16Conference paper (Refereed)
    Abstract [en]

    Basrah is the most beautiful part of Iraq. In terms of size, it is the second largest city after Baghdad. For more than 25 years, Basrah has almost constantly been at war or been in an Aggressive situation. Three major conflicts have dominated, from 1980 to 2003. The wars have brought great suffering to the Basrah population and city. The bombing caused great material damage. Today with reconstruction process the city require to take a stabile process of reconstruction by using environmental cods in urban planning and design which offer an exciting opportunity to achieve environmental, social and economic benefits. The concept of biophilia deserves a deeper explanation. The hypothesis is that this affiliation leads to positive responses in terms of human performance and health even emotional states. The new movement aims to create environmentally friendly, energy-efficient buildings and developments by effectively managing natural resources. This path will discover a far deeper integration of nature with the built environment and the potential synergies in exchanging energy and nutrients across the human-nature interface. The research will take in reading different experiences from 1980 until now, in which we will try to put all practical consideration necessary to be able to select competent urban and architectural elements adequate to Basrah condition.

    Abstract [en]

    Danish landscape and Danish building are inseparable. Aarhus is a beautiful city situate in the western part of Denmark, and the eastern part of Jutland. Long house or one wing house is a traditional type of house that is dominant in Aarhus city, and other parts of Denmark, which goes back to the Iron Age, c.2000B.C. The aggressive effect of wind obliges builder to find a practical solutions to combat the negative effect of strong wind. Wind breaks around houses is a widespread tradition for determinate a better comfort around house and to save energy. The thermal influence on the built form and orientation of buildings has the strongest influence in the countryside.

    Biophilic architecture, the concept of healthy sustainable architecture2006In: PLEA 2006 - 23rd International Conference on Passive and Low Energy Architecture, Conference Proceedings, 2006, p. I383-I386Conference paper (Refereed)
    Abstract [en]

    Today, upon reflecting on the various settings and experiences of our lives, we should be able to find some fairly close matches between characteristics we like and characteristics that would have improved our chances of survival. In our course we perceive that the natural contiguous keeps us healthy and in turn, probably promotes physical performance as well. Occupants of built environments don't want simply to work, play, eat, or sleep in a functional building. They want to be inspired, invigorated, comforted, and reassured by their surroundings. They want spaces that will make them more appropriate, comfortable. Biophilic architecture offers an exciting opportunity to achieve environmental, moral, social and economic benefits. Much remains to be understood about energy, environmental and life-cycle processes to engage young and enthusiastic researchers in the world-wide greenly architecture community and for those interested in biophilic architecture. The concept of biophilia deserves a deeper explanation. The hypothesis is that this affiliation leads to positive responses in terms of human performance and health even emotional states. The new movement aims to create environmentally friendly, energy-efficient buildings and developments by effectively managing natural resources.

    Masonry in the Context of Sustainable Buildings: A Review of the Brick Role in Architecture2022In: Sustainability, E-ISSN 2071-1050, Vol. 14, no 22, article id 14734Article in journal (Refereed)
    Abstract [en]

    The process of combining various parts to create a structure is called building. The most effective and significant component of any construction is masonry. The Colosseum, buildings from ancient Greece and Rome, Central American buildings, and Mycenaean structures all used this material as one of their primary building elements. The oldest form is dry masonry of irregularly shaped stones. The ecological qualities of masonry, as a restorative material with a low impact on the environment, as well as the environmental control capacity of the massive wall, bring masonry back to attention as a suitable material for sustainable building in the context of current concerns for sustainable architecture. This article takes the form of a review of the journey of masonry as the primary construction material—from prehistoric structures to modern-day edifices. This article will go through the fundamentals of masonry construction to support its usage in structures throughout history and in many architectural styles, as a crucial representation of human construction in architectural history. This article aims to create a historical review, presenting masonry as an essential building material and assessing its role in the history of building materials

    Reviewing and Integrating AEC Practices into Industry 6.0: Strategies for Smart and Sustainable Future-Built Environments2023In: Sustainability, E-ISSN 2071-1050, Vol. 15, no 18, article id 13464Article in journal (Refereed)
    Abstract [en]

    This article explores the possible ramifications of incorporating ideas from AEC Industry 6.0 into the design and construction of intelligent, environmentally friendly, and long-lasting structures. This statement highlights the need to shift away from the current methods seen in the AEC Industry 5.0 to effectively respond to the increasing requirement for creative and environmentally sustainable infrastructures. Modern building techniques have been made more efficient and long-lasting because of AEC Industry 6.0’s cutting-edge equipment, cutting-edge digitalization, and ecologically concerned methods. The academic community has thoroughly dissected the many benefits of AEC Industry 5.0. Examples are increased stakeholder involvement, automation, robotics for optimization, decision structures based on data, and careful resource management. However, the difficulties of implementing AEC Industry 6.0 principles are laid bare in this research. It calls for skilled experts who are current on the latest technologies, coordinate the technical expertise of many stakeholders, orchestrate interoperable standards, and strengthen cybersecurity procedures. This study evaluates how well the principles of Industry 6.0 can create smart, long-lasting, and ecologically sound structures. The goal is to specify how these ideas may revolutionize the building industry. In addition, this research provides an in-depth analysis of how the AEC industry might best adopt AEC Industry 6.0, underscoring the sector-wide significance of this paradigm change. This study thoroughly analyzes AEC Industry 6.0 about big data analytics, the IoT, and collaborative robotics. To better understand the potential and potential pitfalls of incorporating AEC Industry 6.0 principles into the construction of buildings, this study examines the interaction between organizational dynamics, human actors, and robotic systems.

    EN JÄMFÖRANDE FALLSTUDIE AV VANLIGT FÖREKOMMANDE FASADMATERIAL I SVERIGE: MILJÖMEDVETNA VAL AV FASADMATERIAL2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The study was conducted by two students in architectural engineering at Jönköping University and includes 15 higher education credits. Collaboration was carried out with PE Teknik and Arkitektur. The purpose was to evaluate the environmental impact of different facade systems using the LCA methodology. Investigation is motivated by the need to address environmental issues in the construction industry, which accounts for 21% of Sweden's total greenhouse gas emissions.

    Qualitative case study was conducted, exploring architects' thought processes when choosing facade materials and how they integrate principles of sustainability into their work. Interviews with architects answered questions about the process and the integration of sustainability. Five external walls with different facade materials and attachments were compared. To answer the question of which facade material has the most climate impact during its product stage, a material study was conducted. The measurement value used in determining the climate impact was carbon dioxide equivalents.

    The choice of facade material was based on lifespan, recyclability, and content of hazardous substances. Architects may have different focus areas, but the choice of facade material is always based on aesthetic and technical considerations. Respondents also emphasized the importance of choosing locally produced materials if possible. The material study showed untreated spruce panels had the lowest climate impact, while aluminum composite panels had the highest. Fastening of wooden panels had the least climate impact, while the fastening of tiles had the most.

    In conclusion, respondents stressed environmental awareness is a significant transition and the results of the study indicate the industry is not fully ready for it yet. Investigation showed that architects are aware of the environmental crisis and integrate sustainability principles into their work through various perspectives depending on the project's focus area.

    Kan mörker förhöja trygghetsupplevelsen i en parkmiljö?: Mörker som planeringsverktyg2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Darkness has for a long time had a big affect of how the humans perceive their spacial environment. When this study is written there is limited research of darkness related to lighting design, which increases interest in getting more knowledge of how darkness can influence the sense of security in a park environment.

    An experiment was conducted during two nights where the authors of this report illuminated a park using an increased focus of darkness, later on comparing this lighting with the park's existing lighting solution. People stopped by and responded to a safety and security experience questionnaire.

    The results clarified that the participants perceived the park with the lighting solution planned with darkness in mind as more secure than the existing lighting. The majority of participants in the survey confirmed that the delimitations had a big impact on how they experienced the park and their sense of security.

    Several factors may have affected the participants answers both nights, for example the weather, the participants mood, the lighting design, etcetera. But for this report the conclusion is that the focus on darkness has influenced the lighting solution and in turn the participants’ experience of the park. This type of planning needs to be tested in several locations so the user can draw a conclusion of how it affect people’s experience of exterior environment.

    The relationship of light exposure to sleep outcomes among office workers. Part 1: Working in the office versus at home before and during the COVID-pandemic2022In: Lighting Research and Technology, ISSN 1477-1535, E-ISSN 1477-0938Article in journal (Refereed)
    Abstract [en]

    The relationship between everyday light exposure and sleep was studied for office workers. The study was conducted during the upswing of the COVID-19 pandemic, enabling a comparison between Office and Home Workdays. Fifteen full-time office employees were monitored for a period of 4–6 weeks. They wore a light-tracking device on their clothes and had a sleep tracker at home. Compared to an Office Workday, light exposure was lower in the afternoon and total sleep time was almost 5 minutes longer on a Home Workday. Sleep efficiency was the same on both workday types. A higher median illuminance level in the afternoon was significantly related to later sleep onset on an Office Workday. Higher median illuminance levels in the morning were related to earlier awakening. Counter to expectations, higher light levels in the evening were also related to earlier awakening. Everyday light exposure matters for sleep quality but may affect circadian functioning differently than the often more extreme light interventions employed in laboratory experiments. Moreover, differences in outcomes between Office and Home Workdays signal the need for further investigation to provide supportive light levels during workhours.

    Field study challenges: Customisation and personalisation during lighting control research in residences2023In: Journal of Physics: Conference Series, Volume 2600, Daylighting & electric lighting, Institute of Physics (IOP), 2023, Vol. 2600, no 11, article id 112009Conference paper (Refereed)
    Abstract [en]

    Residential lighting control can assist in creating a comfortable atmosphere, providing information, and supporting well-being. Field studies are used to investigate lighting control, but study protocol customisation or personalisation may be required due to actual life events and situations. An 8-week field study tested three protocols for effects on behaviour, well-being, and sleep patterns and was executed in 14 apartments during the winter. Light amount and timing were controlled: residents woke up with a dawn simulation, experienced lights turn-off as an indication to leave for work, and were prepared for bed during a dusk simulation scenario. Sleep trackers results showed later and more wide-ranged wake-up and bedtimes than assumed. As expected, the apartments’ different floorplans challenged comparable light exposure. Unexpectedly, several participants requested a reduced wake-up frequency and reported sleeping elsewhere on Fridays and Saturdays. Everybody experienced a full dawn simulation, but some people left home soon after wake-up, calling for lighting control customisation. Real-time field applications may demand a certain level of customisation or personalisation, affecting intentions and results. Discussing and documenting (un)intentional adjustments during final interviews and in scientific publications can benefit in explaining findings and further research.

    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.

    Hur kan utformningen av ett flerbostadshus i en stadsmiljö påverkas av användningen av standard SS-EN 17037:20182020Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Dagsljus är en viktig aspekt för att förebygga ohälsa om dagsljustillgången inte är tillräcklig. I vetenskapliga undersökningar är det bevisat att dagsljus har koppling till människans välbefinnande samt hälsa. Marknadstrender i dagens byggbransch är stadsförtätning, areamaximering, ökad energieffektivitet och arkitekturmode som begränsar dagsljusinsläppet i gamla samt nyproducerade byggnader. I allmänna rådet i Boverkets Byggregler finns det en förenklad metod i standard SS 91 42 01 för beräkning på dagsljus och den hänvisar även till en handberäkningsmetod ”Räkna med dagsljus” som utvecklades år 1987. I dagens moderniserade samhälle behövde standarden en uppdatering för att uppnå dagens verklighet. År 2018 fastställdes en ny dagsljusstandard vid namn SS-EN 17037:2018 ”Dagsljus i byggnader”, med flera aspekter än den förgående. Målet med studien är att undersöka hur ett flerbostadshus utformning kan påverkas av tillämpning av rekommendationerna i den nya dagsljusstandarden. Målsättningen är också att se hur fönsterstorlekar, placering av fönster och reflektionsfaktorer påverkar dagsljusförhållanden i bostäder i en tät stadsmiljö.

     

    Metod: Den kvalitativa undersökningsmetoden som används i denna studie görs genom intervjuer med arkitekter och dagsljusexperter. En fallstudie genomfördes på en byggnad med hjälp av Insight 360 – Light Analysis in Revit 2018. För att samla ytterligare information gjordes en litteraturstudie.

     

    Resultat: Dagens dagsljuskrav i BBR uppnås i de utvalda rummen men med tillämpningen av den svenska standarden SS-EN 17037:2018 ”Dagsljus i byggnader” uppnås rekommendationerna bara i ett rum per lägenhet. Tillämpningen påverkar byggnadens djup i rummen samt bredd. När det gäller aspekterna Mängd dagsljus och Tillgång till direkt solljus uppfylls delvis rekommendationerna i den nya dagsljusstandarden genom justering av fönsterstorleken, -placering och reflektionsfaktorer på utvändiga material. Utifrån arkitektens och dagsljusexperternas perspektiv kommer den nya dagsljusstandarden påverka gestaltningsmöjligheterna för bostäder på grund av komplexiteten. Den kommer försvåra stadsmiljöernas bebyggelser och även kräva speciella projekt med stora områden dock kommer den hjälpa till att skapa ett välbefinnande för människan.

     

    Konsekvenser: En rekommendation är att inte utforma lägenheter som är för djupa med endast fasad åt ett väderstreck. Ljusare ytmaterial och större fönster ger en högre dagsljusfaktor. Lokaler eller liknande bör byggas på bottenvåningen istället för lägenheter för att inte riskera att få bristande dagsljustillgång. Omkringliggande byggnader är en bidragande faktor till sämre dagsljus i byggnaden. SS-EN 17037:2018 ”Dagsljus i byggnader” bör förenklas för att passa in i dagens moderniserade byggnation.

     

    Begränsningar: Arbetet fokuserar endast på möjligheterna att nå rekommendationerna i standarden SS-EN 17037:2018 “Dagsljus i byggnader” och kommer därför inte ta ställning till hur förändring av fönsterstorlekar påverkar energianvändning och ekonomiska aspekter.

    The relationship of light exposure to sleep outcomes among office workers: Part 2: Comparison of days with and without social constraints2022In: Lighting Research and Technology, ISSN 1477-1535, E-ISSN 1477-0938Article in journal (Refereed)
    Abstract [en]

    Social constraints posed by work schedules influence sleep duration and timing. Everyday light exposure can help (or hinder) sleep outcomes. This study investigated the differences in the relationship between light exposure and sleep outcomes on days with and without social constraints using ambulatory assessment for 4?6?weeks for 15 office employees. The effects of light on sleep were investigated for both clock time and wake time (related to individual sleep times). Participants were exposed to more light during the morning and afternoon on workdays, and sleep times were later on days without social constraints. The relationship between light exposure and sleep was more pronounced, or sometimes even only present, for days without social constraints. In addition, no differences were found between clock time and wake time, which underlines the complexity of the relationship between everyday light exposure and sleep. Despite increased light exposure during workdays, the effects of light on sleep were more pronounced on days without social constraints. It may signal that office workers need a more substantial circadian stimulus (i.e. higher light exposure) for light to influence sleep outcomes on days with social constraints.

    The importance of residential dusk and dawn light exposure for sleep quality, health, and well-being2023In: Sleep Medicine Reviews, ISSN 1087-0792, E-ISSN 1532-2955, Vol. 72, no December, article id 101865Article in journal (Refereed)
    Abstract [en]

    Light exposure during twilight plays a critical role in the entrainment of the human circadian system. People are most often at home during dusk and dawn, and light exposure at home – either natural or from electric light – may therefore contribute substantially to sleep and well-being. However, very little research has focused on the effects of home lighting on sleep and well-being, and even less research has investigated the effects of light exposure during twilight. Therefore, a literature study was performed to collect studies on light exposure at home during dusk and dawn. Studies looking at light exposure during dusk and dawn have focused on either electric light intervention (i.e., dusk and dawn simulation) at home or in the laboratory or daylight exposure in the bedroom (i.e., the presence and type of curtains in the bedroom). Most research has focused on dawn simulation during the darker months of the year, often using sunrise alarms. In general, study results pointed to the importance of twilight light exposure at home for sleep and well-being. These results may depend on the characteristics of the user, such as age or chronotype.

    Abstract [en]

    Purpose: BIM have been criticised as a standalone framework and the believe is that the next step in BIM development is cloud computing. The technology simplify planning of a sustainable construction and hasten the building process through a collaborative friendly information management among different project actors. The implementation of the technology hasn’t been that noticeable since companies are struggling to understanding the technologies contribution. The goal of this research is therefore to investigate the potential of using cloud technology in architects daily work with room finish schedule.

    Method: To answer the goal of the study, interviews about room finish schedules have been made with five architect companies to collect empirical data. The company's internal documents of room finish schedule have been analysed and the research also makes a literature study and an observation of the cloud service BIMeye.

    Findings: The study shows that the main differences between an analogue and digital approach are: the link to the model, input of information and management of revisions. The companies have generally a positive attitude towards the technology, but there are doubts about changing their way of working. The cloud service BIMeye meets the companies needs and has great potential to make several tasks, that are considered time consuming in today´s work, more efficient, such as lay-up of rooms, input of information, review of conflicting documents and management of revisions. This mainly through the database's connection to the model and the database's way of managing information more automated.

    Implications: The conclusion that can be made is that great potential is seen with cloud services as a working method for producing room finish schedules. The transition process to cloud services implies a change of working method but not in the final result. Where cloud services entail additional work in the model to enable a connection to the description, but at the same time contributes to an automatic input of information about rooms. Another change in working method is the ability of cloud services to create parameters that differs from the otherwise analogue paper-work. Revisions in the database get a break through throughout the whole description, in contrast to individual adjustments in the document. Recommendations as a result of the study is to inform companies about the possibilities and impact the technology has on their work. In order to achieve an overall perspective in the industry, new solutions are required so that companies see internal profits with the implementation.

    Limitations: The result is considered to be applicable to other architect firms since it has appeared from interviews and document analyses that the companies work in similar ways. However, whether the result of the test of BIMeye can be applied to other cloud services is uncertain. The research’s limitation to disregard investment cost has restrict the study as it is a significant factor when implementing new technology.

    Granskning av 3D-printingens möjligheter vid utformning av byggnader2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: There is today limitations of what is possible to design and in fact produce.

    In industrial construction the focus is on standardization which impedes an individual

    design form, which can be considered an architectural quality. The potential of 3Dprinting

    is growing, which is benefitting design freedom.

    The goal was to evaluate how 3D-printing in Sweden today could increase architects

    possibilities at the design process and be production adapted.

    Method: In a case study at Tengbom in Jönköping, interviews were included with three

    architects. In addition, a literature review, a telephone interview and a focus group

    interview formed the basis of the collected material. As an initial phase, a focus group

    interview was conducted, which resulted in the actors’ opinions about 3D-printing. The

    architect interviews contributed with high credibility regarding architectural qualities,

    which together with the other collection methods gave answers to the studies questions.

    Findings: The study shows that it is possible to print building components in Sweden.

    However it is not possible, with 3D-printing, to produce entire buildings. It can be

    shown that there are obstacles for the introduction of the technology, such as economy,

    Swedish laws and lack of knowledge. These should be reviewed to allow 3D-printing

    as a manufacturing method. With Rapid Ornament Production larger architectural

    qualities will conduce to, where 3D-printing allows unique solutions. Solutions no other

    technology can achieve.

    Implications: Customized and varied buildings can be achieved thanks to 3D-printing.

    Building components such as light weight walls, ornaments and details can be produced

    in Sweden today. One advantage of 3D-printing as a technology, is that it provides

    greater freedom between design and production. For further development of 3Dprinting

    a greater knowledge is recommended for industry stakeholders, regarding the

    drawing tools as well as the 3D-printing technology.

    Limitations: The result is applicable to architects, working at architectural offices

    similar to Tengbom in Jönköping. There have not been deeper studies regarding of

    printing technologies, finances, materials, time or law. A case study as research strategy

    entails an interpretation of the opinions, which limits the generalization of the results.

    Keywords: 3D-printing, design, production, architectural qualities, possibilities,

    limitations, industrial construction.

    Abstract [en]

    The work presented here was developed as a major training activity of the Seminar of Urban Survey by the students of the XXVIII and XXIV cycle doctorate in Science and the Representation of Survey. Survey is the main tool to understand an architectural work and the several features that rule its spatial concept. The architectural complex of Saint Yves at La Sapienza, original place where was based the University of Rome, is full of interesting information to be learned. The building was designed by Francesco Borromini and implemented in the second half of XVII Century: its shape is characterized by a strong centralization, which is the result of the plan design. The plan of the building was born from the composition and interaction of different geometrical shapes, like the circle, the triangle and the hexagon. These shapes are all pivoting around a strong center but creating a complex weave of lines and curves around it. Centrality is enhanced by the giant coupled responds forming six huge pillars joined by the projecting cornice, directly leaned on the Corinthian capitals of the aforementioned columns. The last fillet of the cornice highlights in silhouette the strong intention of the designer, expressed by the multi-curved shape at the base of the dome. Finally we reach the sky at the top of the dome, where shapes melt in the light coming out of the big windows: here moldings are the only elements which keep together the big vertical columns rising from the ground and disappearing in the shadow. The base of the dome gets together the complexity of architectural elements below, reducing it, as the eye rises to the top, to the simplicity of the circle at the base of the skylight turret. This spatial concept, which is like inviting to look up to the “starry sky of the dome”, expresses itself also outside the building through the geometrical concept of the skylight turret. The turret is set up on a circle at the base and rises up following an helicoidal trend, being decorated continuously from the base to the flamed crown at the top. The completion of the turret is represented by a spherical element, probably symbolizing the Globe, suspended above the flames, which are symbolizing the Christian Charity operated by Saint Yves and embodied by the Pope. The entire complex is crowned by the more explicit symbol of the Christian tradition which is placed next to the sky: the Cross. In the architectural complex of Saint Yves, every decoration lives on its own, but its position respect to the whole building enhances its symbolic value, more than the simple decorative one. The virtual reconstruction, both in a bi-dimensional and tri-dimensional way, of the building of Saint Yves at La Sapienza, has been carried out only through a complex integrated survey methodology, made with long-range 3D laser scanners and high-resolution cameras. After some preliminary elaborations of the data resulting from the survey, like organizing and selecting all the points scanned, it has been possible starting the effective virtual reconstruction. Through the analysis of survey data and the selection of appropriate projection planes, horizontal and vertical sections of the model have been extracted to better understand the geometrical concept. This allowed a critical interpretation of the architectural complex, understanding even the most complex shapes and reducing them to simpler ones. From a practical point of view, the tri-dimensional reconstruction has been executed through an hybrid process, melting the geometrical precision of NURBS surfaces, concerning the architectural aspects, and the adaptability of polygonal modeling applied to the organic shapes of the decorations. This methodology allowed to deeply understand the articulated geometrical solutions designed by Borromini, representing a base for further analysis and studies on these issues.

    Approaching urban sustainability: - a minor field study in India2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis aims to enable improved urban sustainability in India and has therefore been conducted at WSP’s office in Delhi. The objective has been to chart the Indian characteristics as well as to identify difficulties regarding urban sustainability. The purpose and objective have been accomplished through the implementation of three research questions. The questions have been answered by a literary review of existing theories and a complementary document analysis. Furthermore, a case study of a new development in India with long-term sustainability in focus of the design has been conducted. For an Indian city to achieve a sustainable urban development, five pillars of sustainability have been identified; political, physical, ecological, social and economic. The ecological, social and economic are pillars from the common definition of sustainability, however they have different meaning and focus in the Indian context. The physical and political pillars are therefore characteristic for the Indian urban development. The physical pillar is added in the Indian context since short term planning and focus on profit is dominating the building industry. The demand for maintenance is because of that larger than the supply which results in a need for more emphasis on the physical built environment. The political pillar is applied because of the concerns for the value and quality of governance actions. It affects the four other pillars since the government should provide guidance, both with instructions and by executions, which is not always apparent. The Indian government has introduced several strategies in order to achieve sustainability in Indian cities. Rating tools for sustainability, such as Leed and Griha, together with the planning of spatial city forms, such as compact city form and mixed land use, which are the main procedures. Benefits in terms of lower interest rates on loans and a quicker clearance are given to developers who intend to build sustainably. Though the many theories and strategies seem ambitious, they are not always as effective when translated into practice. This is partly because of the lack of follow-up and partly the clients focus on quick profit. Thus, India is facing many challenges in order to reach a sustainable urban development. Together with urbanisation and growth in population, corruption is the main challenge since many other follows. These are lack of awareness in the field of sustainability, short term planning and the focus on profit as well as public safety and poverty. If India is serious about developing its cities sustainably, it is significant for the Indian government to take an inspiring role in using and promoting sustainability.

    Abstract

    This thesis presents a proposal of a pier for the future in the town of Jönköping. The proposal is based on individual ideas and desires to develop the Harbor Pier of Jönköping from the municipality as well as the interest of partners.

    Background

    Jönköping is a town that has been under constant development for the past five years. The main goal for the municipality is to unite the town center and one of many plans is to create a new entertainment corridor. At the same time it is important that the Harbor Pier follows this development and improves, so that its strategic position does not get lost. According to the Office of City planning in Jönköping there is a pressure on the municipality to create a more tourist friendly Harbor Pier with additional activities. The commission that we were given was to construct a vision of the pier area with the help of the partners needs. The Office of City planning is the orderer of this project.

    Implementation, Result and Conclusion

    To create understanding and setting of the paper we have gathered historical facts about the pier area and interviewed important partners for the thesis. Fieldtrips have been done for inspiration and collection of information that relates to the different conditions that creates a harbor. The sketches and drawings have regularly been edited and corrected because of the constant change of ideas. On the basis of this we have supplied a building program that resulted to the design of the Harbor Pier. Together with our own thoughts, the outcome of this is a proposal of the future Harbor Pier of Jönköping.

    This proposal presents five different areas that have been analyzed and prepared in detail. The design has resulted to a new entry to the Harbor Pier that is more functional and attractive than the one that exists today. The proposal also presents a new harbor for smaller boats that connects to a youth hostel along with a bath and a recreation area. A new complex has enriched the pier arm where the town sailing society has their activities today. This complex consists of a marine shop that integrates with a restaurant. A stage has also been established in this area to promote the towns’ cultural life and upbeat the nightlife of Jönköping. To finally create a feeling of tourism in Jönköpings’ harbor, sandy beaches have been planned east of the existing restaurants. This result has also been produced in a three-dimensional environment to gain the understanding of the new vision.

    The conclusion of this thesis is that the different partners’ wishes have been fulfilled at the same time as our own ideas have resulted into a socially functioned harbor with many different activities and an exiting environment.

    Cirkulär hantering av trämaterial: En studie om hinder och möjligheter för att lyfta placeringen av träavfall i avfallshierarkin på kommunal nivå2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction (and aim) – Wood is a renewable material with many advantages for the climate. However, its management is largely linear, leading to significant waste and faster depletion of the earth's resources. Transitioning to a circular model for managing wood materials would reduce waste and carbon dioxide emissions. Minimizing, reusing, and recycling are important for reducing human climate impact, as today's linear flow contributes to low utilization and decreased raw material availability. The purpose of this study is to investigate the current management of untreated wood waste in the municipalities of Jönköping, Mullsjö, and Habo and explore the possibilities for a more circular process. 

    Method – The method applied is a qualitative approach. To answer the research questions, semi-structured interviews and document analysis were conducted, as well as a small literature review. 

    Results – The results of the investigation include several interview responses from officials in the municipalities and the municipally-owned waste company. In addition to interviews, several selected documents were reviewed to supplement the data material. The results from the two different data collection methods were compiled in tables to answer the study's research questions in a systematic and structured manner. 

    Analysis – The study shows that the municipalities generally work with and take various preventive measures against waste. The municipalities' waste management follows the waste hierarchy. However, regulations on the management of wood waste are needed to achieve real change. The government has not yet introduced new requirements that can strengthen development. 

    Currently, the municipalities' joint waste plan does not have specific goals for circular management of wood waste. The study participants emphasize the need for quality stamps on the wood material and more activities that take care of the wood before it reaches the waste phase. This indicates the need for increased capacity for wood waste management that can contribute to more circular and sustainable material flows. 

    Discussion – The study confirms the challenge that arises with today's linear perspective, which hinders the implementation of circular management of wood. By using the selected methods, more solutions to the problem have emerged. The study's results have a strong connection to the sources presented in the theoretical section.

    Evidensbaserad utformning och utvärdering av övergångsprocessen till ett effektivt aktivitetsbaserat kontor2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: With the vast changes in the work life comes changes in the office design. One of the newest on the market is ABW (Activity Based Workplace), were the employees themselves chooses were to sit in the office depending on what fits them best according to the moment. This thesis contributes with knowledge that is necessary for an organisation to know before they begin using an ABW.

    The goal is to evaluate how an efficient ABW-environment is created. An ABW are efficient when the workplace concept works the way it is supposed to do and with that provides good results from the recourses that are available. This thesis addresses the implementation of the transition to an ABW from a traditional office type and how the office design could look from evidence-based results.

    Method: The main strategy for this thesis is a case study that involves the organisation NCC. That is because the evidence-based design is based on their workforce and their office building. The thesis goal is achieved through four different data collection methods: literature study, interview, observation and guidance form an architect. These methods were chosen to gather both qualitative and quantitatively data.

    Findings: The findings are divided into three areas: the first question of issue presents the different office types performances, there are both advantages and disadvantages with all office types. The advantages that can be found in these office types is for instance the cell offices privacy, the open landscapes interaction possibilities and that the kombi office retain the social environment whilst still give privacy from other employees. Whereas availability and flexibility are the most significant advantage of an ABW. Some disadvantages are how cell offices can be unwelcoming, the open landscapes noise level and the fact that you can not work in teams in a kombi office.

    The second finding is the evidence-based office design proposal, from an efficiency point of view. A collocation of the factors that needs to be thought of when designing an ABW is the fundament of this proposition. Some of these factors are for example the possibility to privacy, have co-workers nearby and distinct zone divisions.

    The third finding of the thesis demonstrate an evaluation of the transition to an ABW. An evaluation has shown to be necessary when establishing an efficient ABW. One of the most important part is to understand the employees, meet their needs and let them be heard.

    Implication: It takes both well planned transition and good design for an ABW to preform efficiently. Design and efficiency depend on each other and there are a few distinguished factors of what makes a workplace environment efficient. When talking about the transition to an ABW it is important to have a substantial process were the employees are given the possibility to be involved and informed of the ABW-concept and its impact.

    Limitations: The main limitations of this thesis are from a design perspective, such as artificial lightning, technical equipment and ventilation. The focus instead lies with the placement of walls and rooms, as well as furnishing. The economy aspect is also something that has not been taken into consideration, either when designing or in the evaluation process. This is maintained by defining the searches and stay focused.

    Aktivering av social hållbarhet genom att skapa ett kollektivhus i Jönköping2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction (and purpose)- We as humans and as engineers need to build in a sustainable manner for the families of today while considering the coming generations.A new type of collective housing is hence needed in Jönköping that could ensure building in a more social sustainable way. The purpose of this study is to help in understanding which aspects people prefer in a collective house and further on illustrate the floorplans of a collective house based on the survey’s results.

    Method – Literature study was used to acquire all relevant knowledge about social sustainability and collective housing. A quantitative survey was then used to study the housing conditions of different families and the relationships they have with their neighbours.

    Results – Respondents that were interested in social sustainability as a concept and collective housing as a way of living answered the web-based questionnaire. Living in a good location, in a safe area and having good relationships with neighbours were the most important aspects in a household. The economical- and social factors ranked as the most important driving factors that would make families consider moving into a collective house. Approximately half of the respondents had no relationship with their neighbours and just greeted them when they ran into each other, while a large number of respondents believed that a stronger relationship could be formed with their neighbours if they had a place in the building to share a hobby with them. An illustration of a multi-family collective housing will be presented which was a combination of people’s opinion, literature, and cases.

    Analysis – Many respondents prioritized living close by to schools, work, or city. This is because a person’s surroundings can affect their feeling of safety in an area, thus helping them form social networks with those sharing those same surroundings. This inturn, helps prolong a households age which creates a stable and safe environment for the residents. The entrance point of the building is usually its main entrance, however due to the respondents answers the street around the building marks the beginning of the journey from the surrounding site and throughout the building.

    Discussion – The high response that the questionnaire gathered was a result of the respondent’s interest in social sustainability or collective housing. Respondents belonged to different age groups which ensured a high reliability. A higher reliability could have been ensured if it was for example shared with people who are already living in collective housing as they would have a clearer idea on what it is like to live in one,and their experiences could have been fruitful to the thesis. One’s psychological health is known to be enhanced through the interaction that the people can have in their buildings shared premises. Choosing a location for the illustration of the house would have changed the buildings architectural form, gave different window placement, other entrances, amongst others. The methods chosen for this study was however reliable as they created a clear path for the authors to guide in illustrating the building so that a person could visualise the respondents answers instead of just reading them.

    Dimming strategies for open office lighting: User experience and acceptance2019In: Lighting Research and Technology, ISSN 1477-1535, E-ISSN 1477-0938, Vol. 51, no 4, p. 513-529Article in journal (Refereed)
    Abstract [en]

    Sensor-triggered control strategies can limit the energy consumption of lighting by considering the presence of users in the office and dimming lighting down when it is not needed. In multi-user offices, the application of occupancy-based dimming at room level limits the energy saving potential. However, zone- or desk-based dimming may affect the comfort of co-workers due to its dynamics. This paper reports the assessment by 17 participants (30–50 years of age) of occupancy-based dimming in a mock-up office, using different dimming speeds. Participants consisted of co-workers experiencing changes triggered by others, and actors triggering these light changes. While the participants performed an office-based task, the luminaire above the actors’ desk was dimmed from approximately 550 lx to 350 lx (average horizontal illuminance), and vice versa. The participants evaluated the dimming conditions regarding their noticeability and acceptability. The study showed that the noticeability of light changes due to dimming, increases when fading times become shorter. Dimming with a fading time of at least two seconds was experienced as acceptable by more than 70% of the participants. The results of this experiment provide insights to system behaviour that does not compromise user experience while addressing energy efficient use of electric lighting.

    SABOs kombohus som senioranpassat boende2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Många av SABOs typhus, kombohusen, har en majoritet av hyresgäster över 65 år. Detta var inte planerat vid utformning av bostadshusen utan tanken var att bygga ett flerbostadshus till ett lågt pris. Därför kan kombohusen sakna produkter och utformning som äldre hyresgäster behöver. Ett kombohus kan se olika ut men det de har gemensamt är att de är upphandlade av SABO och kan avropas av deras medlemsföretag. Kombohusen har även vissa likheter i form av produktval och utformning av lägenheterna. Bostäderna uppfyller SIS-standard men det betyder inte att allt är anpassat för en äldre hyresgäst. Eftersom andelen seniorer i Sverige ökar så kommer det behövas fler tillgängliga bostäder. Målet i denna undersökning handlar därför om att utvärdera SABOs kombohus och identifiera faktorer som kan förbättras för att åstadkomma ett bättre anpassat boende för seniorer.

    Metod: I studien har fem olika kombohus undersökts utifrån ett tillgänglighetsperspektiv där den huvudsakliga metod som använts är intervjuer. De intervjuade är hyresgäster som brukar en lägenhet i kombohusen samt bostadsföretagen som har låtit uppföra byggnaden. Studien består även av en fallstudie där en inventering av miljöhinder (tillgänglighetsgranskning) har utförts med hjälp av Housing Enabler Screening Tool. Verktyget behandlar punkter inom olika områden: inomhus, entréer och utomhusmiljöer. Om byggnaden inte uppfyller någon punkt får den en anmärkning inom det specifika området.

    Resultat: Undersökningen har visat att de flesta anmärkningarna hos kombohuset har varit inomhus. Även att det kombohus som klarade sig bäst var i Ronneby som är ett kombohus anpassat till trygghetsboende vilket bland annat innebär förhöjd tillgänglighet i badrum. I studien har författarna kommit fram med förslag för att förbättra framtidens kombohus för att kunna åstadkomma ett bättre anpassat boende för seniorer med hänsyn till tillgänglighet.

    Konsekvenser: Slutsatser som har tagits är att konceptet med kombohuset har stora möjligheter att i framtiden ge fler tillgängliga bostäder på marknader där det verkligen behövs. Dessutom att några av de kontrollerade punkterna är lite svagare och bör åtgärdas även i det befintliga beståndet. Exempel en sådan punkt är utrymme för rollator i lättillgängligt förråd eller förvaringsmöjligheter i trapphus som inte utgör en brandfara eller blockerar utrymningsvägar då många hyresgäster i kombohusen använder sig av rollator. En slutsats som författarna har kommit fram till är att många av de intervjuade anser att det görs för lite uppföljning av hur hyresgästerna upplever boendet. Fler uppföljningar tillsammans med hyresgäster med hänsyn till tillexempel arkitektur och utformning är en stark rekommendation.

    Begränsningar: Studien baseras på empiri från fem kombohus men detta anses vara tillräckligt då kombohusen är typhus och många är utformade på samma sätt. Studiens resultat skulle därför troligtvis vara samma även om andra kombohus hade valts.
