    Travelling Stockholm from underneath: A journey of light2015Independent thesis Advanced level (degree of Master (Two Years)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    The report Stockholm city’s regional biking plan presents information of a continuously rising numbers ofcyclists in central Stockholm. However, the central parts of Stockholm have not now, or in the near future,the capacity or structure to provide a functional as well as safe traffic situation, especially for cyclists. Theincreasing demand from traffic of the commuter street network in central Stockholm make the 6 km longunderground maintenance tunnel along the newly build Citybanan commuter train tracks a possible andinteresting alternative for safe, fast and easy bicycle travelling underneath Stockholm. The tunnel stretchesfrom Fatbursparken to Tomteboda, with exits/entrances along the route in central parts of Stockholm[Fig 1.]There are several examples in the world where former car, train and maintenance tunnels are used as bikingtunnels. The longest existing example is the Croix Rousse tunnel in Lyon, France (2013). A 1,3 km longtunnel with separate lanes for cyclists, pedestrians and commuter busses, which also functions as anevacuation tunnel to the parallel car tunnel. Another example is the Lugaritz-Morland bicycle tunnel in thecity of San Sebastian, Spain (2009), which is a former railway tunnel (850 metres) that connects twoneighbourhoods in the city.The specific conditions a tunnel have with no daylight and limited access, give the lighting designer theimportant task to shape the space using light.Light is the factor that makes us see the world, our visual ability is depending on the light. Light has theability to reveal and transform the character of a space and influence how the observer experiences thesituation, both physically (by vision) and psychologically (emotional experiences as comfort and feeling ofsafety). Therefore a good visual condition in public space, traffic as well as enclosed spaces like tunnels, arevery important and a basic need for humans in the city.The aim with this thesis was to develop a lighting strategy and proposal for the maintenance tunnel ofCitybanan in Stockholm, based on literature and case studies research, a full-scale light observation by areference group in a tunnel context as well as research by questionnaires. The primary purpose of the fullscalelight study was to confirm literature research hypotheses about the importance of light distributionand experienced spatial atmosphere in relation to psychological effects, as well as the importance of lightgiving information. Findings confirm and shows that light distribution have a great impact on how theobservers experience the space visually, as well as emotionally. Findings also show that light can influencepeople’s behaviour to intuitively slow down or be alert. Further this thesis results show that giving a spaceit’s own identity by collaboration between light, colour and architectural elements have a great impact onthe psychological experiences of a space regarding safety, comfort and social interaction, crucial factors in atunnel environment for cyclists.The thesis results in a concept presented in the Proposal chapter, based on design principles and a lightingstrategy where a combination of light typologies is used to create a human centred and comfortableenvironment. Light is used as guiding element and for spatial understanding to create comfort and supportsocial interaction. In addition the concept includes a theme used as inspiration in the lighting strategy tocreate a connection on a human scale between the cyclist and the space. The theme is based on a commonpreference of the reference group, as well as my personal, for the ideal dream biking environment;In the nature. Experiencing for example the variation of light filtered through the leaves, the sunset and theabsence of traffic.The aim with the proposal is to transform the tunnel to an attractive bicycle route for daily cyclists inStockholm, as well as being an interesting tourist attraction.- A large underground landmark and art piece stretching under the city of Stockholm.

    Light Memory, as a Design Tool: Is there are common light memories for users that share the same specifics of the cultureassociated to the availability of daylight? How could this specific visual light memory be used as a design tool to recreate a similaremotional experience for users?2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    “Light memories” are visual episodic memories of a lighting composition that transcendedan emotional response. The study considers the memories and how they could be a wayto integrate users in the design process. Both designs and memories are considered twosubjective elements, for both designers and users. The purpose of the thesis is to firstly testif there are common light memories for users that share the same specifics of the cultureassociated to the availability of daylight and secondly to explore the possibility of creatinga design method to incorporate this light memory as a design tool, to recreate the similaremotional response of the memory in a newly designed setting.

    Two street typologies in Egypt were chosen to be the visual memories to be assessed. Apersonal daylight analysis was conducted to understand the designer’s perspective. And avirtual reality experiment was conducted along with descriptive questionnaire to understandthe emotional response of users to these streets. A comparison of the designer and usersresults helped in the creation of a scheme for design. The proposed method suggests theusage of perceptual tools such as the light distribution and contrast ratios and proposesthe analysis of the memory in terms of scales. The method is applied in the creation of twoexperiential models that abstract the essence of the light memories and puts them intoquestion for subjects to evaluate. The emotional response of users is recorded to evaluatethe method application.

    Based on the tests it was found that the existing of a common memory is possible. Theevaluation of the specific street memory through the experiential model results show that ahigh percentage among the users sharing the same daylight culture recognized the streets.Although most users had the same emotional responses to the models, but the agreementon the emotional percentage amongst them was lower than the recognition results.This indicates that the memory could be integrated into the design process but wouldn’tnecessarily have the same emotional impact on users. Having a strict design methodology isdifficult to implement yet could be an eye opener for ways to use the light memories.

    The Perceptual and Psychological Effects of Artificial Lighting on Peripheral Vision in Humans2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Information processing differences between foveal and peripheral vision allow for different perceptual experiences and emotional responses. A lighting set-up was used to test the spatial perception and emotional state of 14 participants with the use of foveal and peripheral vision in a photograph and immersive environment respectively.  The space was associated with high levels of tension, inspiration, and alertness and was regarded as being more spacious, with higher light intensity, and more uniform lighting distribution when perceived with peripheral vision.

    Inner yard building occupant’s perception versus the computer simulated metrics of daylight: Field study and simulation-based analysis of inner yard building2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This Master thesis was aimed at investigating common daylight evaluation methods related to Swedish building codes versus human perception of daylight in residential spaces. Field (interview) and simulation-based study were conducted in one of the typical 20thcentury residential, closed courtyard buildings in Stockholm.

     

    12 residents of Kv. Väktaren 16 were interviewed and simulation models were prepared for the apartments occupied by the participants.

     

    Resident perception of light was mostly contrary to daylight assessing values and methods of daylight factor – DF in a point (CIE overcast sky) and alternative method of window to floor area ratio – AF that are stated in Swedish standard (Boverkets byggregler BFS 2016:6). 

     

    Attractive and interesting view, access to direct sunlight and visual comfort played important role in overall occupant satisfaction level, this suggests that daylight metrics should include perception-based factors, which positively impact our health and well-being.

    Light and Perception of safety in-between buildings: The role of lighting in perception of safety from a female perspective in in-between spaces of residential areas2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis will investigate the relationship between lighting and perception of safety through a case study. The main focus of this study is outdoor lighting with consideration of gender equality and perception of safety. Although street lighting is generally recognized as the most important environmental features that influences subjective perception of safety after dark, there is still lack of knowledge regarding the needed quality of light for this purpose and how it may influence perceived safety. Literature review indicates that effect of light on perceived safety works through two different mechanisms: natural surveillance and social integration. The main focus of this thesis is on natural surveillance. Indeed, light by increasing visibility in interaction with presence of people, enhance possibilities of natural surveillance. Based on literature review, a tool has been developed to have a more specific examination of visibility.Besides, the women’s safety audit (WSA) diagnostic tool is used as a qualitative data collection tool to identify unsafe spots in the chosen area by 10 local female participants. The chosen area is a residential area in Eskilstuna city, called Årby neighbourhood. All the participants were asked to determine unsafe spots from their perspective in the chosen area during an exploratory night walk. In the next step, the identified unsafe spots are analysed by means of the developed tool in terms of visibility.The result of this thesis supports the previous findings regarding the relationship between visibility and safety perception. Results show that urban settings with low level of prospect (obstructed view), high level of entrapment (escape difficulty), high level of concealment (lots of hiding spots), lack of illuminated visual spatial boundaries (sky plane, vertical plane and ground plane), low level of facial recognition and obstacle detection, low level of illumination of path, high level of glare and varied lighting distribution are judged as the most unsafe by women. In addition, the study revealed that illuminated ground plane has the minimum impact on sense of safety in comparison with other safety-related environmental factors. Consequently, this study highlighted that standards and guidelines, which are related to ground plane, are not very beneficial for improving perception of safety.

    The metamorphosis of feelings: Approaching a sensorial visual design based on audible perceptions2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Atmospheres, events, feelings, every sensation has its own music. And the human being has been highly educated to feel the glamour of them through the hearing sense. We know how a terrifying situation sounds like; what would be the musical accompaniment for a warzone scenario or what is the perfect piece for getting into a state of relaxation. Thanks to music design it has been possible to immerse the spectator into a deeper sensorial perception experience. Users close their eyes, and feel. What if we close our ears, and feel?

    This thesis aims to transport the qualities of sound that produces feelings into people, to visual values communicated by an approach to architectural lighting design into architectural spaces.

    A music example is chosen according to the intended emotion to be transposed. It is analysed, evaluated and related to a series of theoretical fundamentals based on visual psychology, human experience, multisensorial connections and lighting design. Laws of correlation are stablished and applied to a case study which ends as a theoretical concept design of an architectural lighting design installation.

    Closing the document, a statement of guidelines for the conversion of subjective emotional qualities perceived from musical examples is stablished and discussed the use of it in architecture.

    LIGHT AS A TOOL TO STRUCTURE URBAN PLANNING: A Socially-Oriented Approach2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    How can light positively influence and encourage pedestrians’ engagement and interaction with the urban environments at night? In this Master Thesis, I questioned how to develop nighttime urban planning from a socially-oriented approach. In order to answer this question, I studied different evidence such as two publications, three lighting designers’ and a lighting studio’ approach; three case studies analyses, two of them located in Colombia (Cartagena and Medellín) and one in Sweden (Stockholm);and my own qualitative observation and quantitative measurements studied between April and May at Norrmalmstorg and Biblioteksgatan in Stockholm, Sweden. From that review, I propose a Guideline consisted of three sections: (1) Main dimensions, (2) lighting attributes, and (3) lighting systems in urban planning. In general, this guideline is a framework to develop the analytical tools for various design stages in nighttime urban planning.

    Outdoor lighting in Icelandic schoolyards: The importance of outdoor lighting during the dark winter days2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Schoolyards play an important role in the Icelandic education system. Students aged 6 to 12 years old are required to go outdoors for recess at least two times per day. To play, get fresh air and to regain energy for upcoming classes. The schoolyards are even sometimes used for outdoor education where the students can experience their nearest environment. The children spend a great time of their childhood in school, which should support their well-being by offering an environment of good quality.The thesis main objective is to examine the importance of outdoor lighting in Icelandic schoolyards by the dark winter days. Since Iceland is located at high latitudes, the amount of daylight varies between seasons, with shorter days by winter but longer and brighter days by the summer.The structure of the thesis is a combination of research background and a case study. The research background introduces the positive link between the outdoors and well-being and how the mindset towards the winter can change the perception of darkness. Possibilities of outdoor lighting are examined, how lighting can contribute to the users and the identity of urban spaces. The case study examines two Icelandic schools where the current conditions are analyzed. Qualitative interviews were carried out to gain insight from school employees about the school environment and their experience of the students‘ well-being during the dark winter months. Finally, a lighting proposal is introduced that illustrates how layers of light can enrich the school outdoor environment.It can be truly said that outdoor lighting is of high importance in Icelandic schoolyards, for the students to see and experience the schoolyard by dark winter days. It is important that the lighting is in context with the schoolyard elements and thereby enhancing the quality of the environment.

    Daylight openings in art museum galleries: A link between art and the outdoor environment2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis is investigating how the typology of daylight openings in art museum galleries is affecting the connection to the outdoor environment. Museum architecture nowadays emphasizes on the museum’s public role and interaction with the urban context, with transparency as the key to this approach. Considering the benefits and challenges of introducing natural light in art museum galleries, its controlled use enhances the experience of both the artworks and the space. The different typologies of daylighting and their design parameters have a direct impact on the connection to the outdoor environment and the shaping of views. Two case studies are analyzed in order to investigate various daylight openings designs, their integration in the exhibition space and the relationship they form with the exterior. Examining the findings, a discussion is developed on the range of factors that affect the connection to the outdoors. The thesis concludes that the design of daylight openings determines the way and the degree the galleries communicate with the exterior environment.

    Light as a medium to enhance communication in urban spaces2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Τaking into consideration how frequent the presence of light is in the most of the communication events and initiatives of human beings, as well as, the continuous need of the society for an evolution and facilitation of communication, without barriers, this thesis aims to study how light can be an impactful medium, suitable to influence and create, a social worldwide engagement οn a daily basis.

    Βy applying current techniques and methodologies of the field, through the published bibliography and articles, the collection and presentation of the existing projects, original interviews and questionnaires, this research, attempts to present significant reasons and arguments that designate the light as a basic communication tool, suitable to dynamically contribute in transferring messages and information on sociopolitical, environmental and health-related fields.

    In the end, it is justified that light under a certain context is an attractive medium, suitable for raising awareness, communicating messages for local and global issues and creating social engagement in the urban space. By providing arguments for the importance of the use of light in sociopolitical, environmental and health issues, emphasizing on the dynamic lighting environments that can communicate information through light, this research concludes with an aspiration for more conscious use of this communicative “language” in the urban space.

    Through the final conclusions, it is evident that the continuation of a constructive dialogue on the subject will help solidify the position of light as a fundamental and meaningful communication medium. For that reason, the discussions and conclusions will give the audience and researchers the incentive to dive deeper into the issue and investigate the many aspects of it in further analysis.

    Principles of Designing an Experiential Lighting Showroom: Finding the Balance between Demonstrating the Experiential and the Technical-Aesthetical Qualities of Luminaires2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    An analysis of existing showrooms showed that absence of atmosphere makes it hard for clients to imagine effects in a context, and that lack of guidance by the light makes the experience of the showroom overwhelming or static. Also, clients often prioritize luminaires' design over light effect, even in architectural lighting where design should be negligible. This thesis investigates whether it is possible by prioritizing light effect, to optimize the showroom experience and to direct clients' focus on the light, while minimizing the influence of design on the impression and eventually choice of luminaire. In order to achieve these goals, three main concepts are suggested – guiding light, contrasting atmospheres and sequence of presenting light effects first and luminaires afterwards. These enable good communication about light which is essential for clients to focus on the atmosphere created by the light, rather than price and design. Experiments were conducted in the basement of a Croatian company's office, where the exhibits were not the luminaires, but their light. Visitors' priorities before and after going through the installation changed significantly, which might mean that the light effect made an impact and influenced examinees to base their choice of luminaire more on light effect, than design. It is concluded that the used concepts contributed to putting more focus on the light itself. Instead of focusing solely on light experience or product, a balance between the two was achieved by prioritizing and showing the light effect first, and only afterwards joining it with the product, thus offering visitors a more complete experience of the luminaire.

    Ljus och hälsa: En kunskapssammanställning med fokus på dagsljusets betydelse i inomhusmiljö2017Report (Refereed)
    Abstract [en]

    This report reports the published evidence in scientific papers with a focus on Nordic research, but also includes relevant technical reports and books. The results are mainly presented for the non-visual effects of daylight.

    The report indicates that more attention should be paid to the health-promoting effects that natural daylight provides in the living environment. Building design is the most important determining factor for natural daylight exposure in times when the general trend is for reduced time spent outdoors. It is especially important to consider good lighting at schools and in health care facilities.

    Light is crucial for the regulation of circadian rhythms, sleeping and waking cycles, the regulation of mood, and the activation of stress responses. 

    including access to daylight, windows, and views, becomes crucial. Good access to natural daylight in the environment facilitates the regulation of circadian rhythms and improves sleep, and daylight entering through windows promotes orientation in the room, reduces falls, and prevents depressive symptoms.

    There is a linear relation between time spent outdoors and good health, and the more natural daylight that is obtained, the fewer the health complaints that are reported. In an environment devoid of daylight, sensitivity to other evening light sources such as computer screens and tablets increases, and this affects sleep and circadian rhythms negatively.

    The influence of opening's embrasure and view on the perception of an interior space2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    “The influence of opening’s embrasure and view on the perception of an interior space”

    By different penetrations of natural light in a similar interior space, the perception of the room will be affected. Moreover, the nature of the view visible through the opening will engender distinct feelings regarding the same space. Three unique models composed of specific “direct-indirect” openings have been evaluated by sixteen observers throughout the months of April & May 2018, in Switzerland. Although the Daylight Factor* and the Illuminance* generate similar values in between the three Models, the room beneficial of a stronger daylight penetration and a more inclined embrasure* provokes a higher qualification of the space. In addition, the type of the view impacts the perception of the room. An even and flat view, in opposition to a natural background, has the tendency to generate undervaluations of the space in terms of General Impressions but also Spatial Brightness, Spatial Complexity and Spaciousness.

    The following paper is divided in three parts: firstly a theoretical development regarding the natural light and the architecture, secondly the practical experiment and, finally, the discussion, which invites a dialogue between the first two sections.

    Is Human Centric Lighting Really Human Centric in a Classroom?: A holistic evaluation of a HCL-system in a classroom2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to evaluate Human Centric Lighting in a classroom. Previous studies tend to focus primarily on the biological, non-visual, effects of the HCL. In this study, a more holistic approach to HCL is applied, including both the non-visual aspects as well as the visual and emotional aspects.

     

    In order to fulfil the aim of the study, the three aspects - visual, emotional and biological - will be investigated through five different methodologies; observation and analysis of lighting distribution and behavioural analysis of lighting system as a visual aspect, surveys about the mood and emotions as an emotional aspect and visual performance and visual acuity as a biological aspect.

     

    The evaluation took place in the elementary school Sturebyskolan in Stockholm, where a classroom with a HCL-system is to be found. The system includes three lighting settings; 800 lx, 6000 K (energy light/focus light), 500 lx, 4000 K (standard/normal light) and 300 lx, 3000 K (calm/relaxed light).

     

    Results show positive effect on performance and better visual acuity in focus lighting than in relaxed lighting. Focus lighting was perceived as a cold and hard lighting for tests, while the relaxed lighting was perceived as a warm and calm lighting for a cosy feeling. The lighting characteristics are suited for a typical classroom. The ignorance of the lighting system can be a problem for the experience and usage of the lighting in the classroom.

     

    In summary, to denominate a lighting system as HCL and only consider the altered colour temperature and light intensity is not comprehensive enough. A HCL-system needs to consider the visual, emotional and biological aspects, and the biological aspect is explicitly considered in this lighting-system, whilst the emotional and visual aspects are more ambiguously considered.

     

    As a proposal to consider all three aspects, several layers of light could be added in order to strengthen the visual aspect and create a vivid and interesting atmosphere. Moreover, conscious arrangement of luminaires and luminaires with flexible characteristics could simplify and broaden the opportunities in the classroom and facilitate the use of light layers.

    Crisis of Window. Lost Purpose of Daylight Opening2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis concentrates on problematic field of architectural education and practice related to window role. Phenomena of window loosing it’s primary functional purpose [inside-outside connection in terms of view and daylight] and becoming more decorative element of the facade. This paper content consists of analysis of case studies by evaluating window provided light and view qualities using qualitative and quantitative methods in chosen office buildings. Analysis and results are followed by the discussion of window role oppositions between architect’s and user’s perspective together with secondary topics coming out of it. As the result of analysis and discussion - guidelines for window design are suggested and conclusive experiment of their customization is demonstrated. This thesis  concentrates on awareness of window identity crisis as well as examine and provide simple manners, which can increase quality of daylight and view through the openings in architectural planning.

    Indirect Lighting in Contemplative Architecture: A study of Depth2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Contemplation and illumination. The reasons behind this thesis were born in an attempt to understand a relation that have existed for millenia and that, at the same time, touches essential grounds of our being and our states of consciousness.Many approaches have made me understand that it is through the essence of these experiences that this topic can be better addressed. Delving into the phenomenology of the architectonic contemplation states, I manage to collect the necessary tools to study and gather information on the typical aspects of these lighting solutions that have an influence on the perception of spaces. First by defining the main characteristics of the indirect lighting, and then, by studying sensitive descriptions of contemplative spaces with these solutions, I have been able to highlight a series of qualities that are typical of the relation between this two worlds. The constant suggestion of a perception of infinity in these descriptions drove this thesis to the analysis of the perception of depth. Different attributes of the perception of this infinity suggested a link between the direction in which the indirect light-sources are set, and these never-ending spaces. The study of and endless depth has shown to be only approachable through the use of metaphoric descriptions, what took me to highlight the value of words, understanding it as a tool that may extend the scope of our experiences.In a last chapter, the artwork of James Turrell has been approached from two different angles. First providing an overview of his work, and second by comparing two of my personal experiences through his art. The outcome showed a tight relation with the previous findings, but also strengthening the importance of the value of knowledge, expectations and emotions. Contributing, in this way, to the creative field by bringing into light certain aspects that we generally do not consider and that have a transcendental influence in the experiences of those to whom our labour is aimed at.

    Shared spaces have proven to be the most sustainable solution in the midst of growing demand to implement sustainable lifestyles and at present, co-living is the most trending housing option. In these coliving spaces, the common shared spaces are very important among which kitchen is the most critical one as most of the tasks are carried out there. The main objective of this study is to find if a relationship exists between task lighting, illuminance and multiple users in shared residential kitchens. Limited research in this area has been the primary motivation for this study. Furthermore, during the course of the study, the importance of flexibility in the task lighting for shared residential kitchens was investigated.

     

    Realizing the objectives, the study aims at answering the following main investigation questions:

    • Is task lighting in a shared kitchen designed with the number of users in mind and does it consider the different ways in which they perform different tasks at the same time?
    • Should the lighting design standards be reconsidered for shared residential kitchens?
    • Would flexibility in the lighting devices be beneficial for shared kitchens ?

    The main investigation questions are answered with the help of the following sub-investigation questions which mainly highlights the relation between the multiple users, illuminance and task performances.

    • Do multiple users affect the various performances carried out in a shared kitchen?
    • Are there any shadows cast by the multiple users in a shared kitchen? Do they affect the illuminance levels in the task areas and thereby affect the visual and task performances?

     

    Case studies of two different shared residential kitchens were carried out. The methodology of the case study involved two stages, complete site analysis and an experiment.

    The experimental set up is adapted from McGuiness, Boyce and Harker‘s investigation study “The effects of illuminance on task performance in domestic kitchens” and was modified to suit this  study. The experiment was conducted in two different scenarios. Quantitative and qualitative analysis was carried out during the study.

    The end results of the experiment proved that there is a strong influence of multiple users on the task performances without having any major impacts on the lighting conditions. This indicated that new lighting standards have to be framed for shared residential kitchens in the aspects of ergonomics and flexibility. The importance of flexibility in shared spaces and in shared residential kitchens was realised was considered just beneficial in terms of mood, comfortability and practicality.

    Light art in Contemporary Architectural Lighting Design2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This research focuses on understanding the relationship betweenlight art and architectural lighting design and determining towhat extent can aspects of light art be used when designingfunctional lighting for architecture.The first part of this paper looks into the historical applicationof light as a material. Light has been an important element inart even prior to the introduction of artificial light sources, butthe exploration of light as an independent material throughinstallation art only developed in the last century. Similarly inarchitecture, the impact of light on creating and shaping spaceshas been recognized since ancient times, yet it was much longerbefore the development of lighting design as an autonomousdiscipline.In recent years there is an increased need for creative expressionfrom lighting designers who are pushing the boundaries ofcommunication through light. In order to understand the extentto which successful innovative lighting schemes can drawinspiration from artwork, this research further analyses keyvisual and emotional properties of light art, as well as potentialconstraints of functional spaces. Distinction of roles of the artistand designer as well as the conditions in which they work withthe medium of light pose a challenge in relating these twodisciplines.Findings from first two parts of this research are further used toanalyse an example of an architectural lighting project, to drawconclusions about light art’s applicability to functional lighting.

    'Swedish Healthy Home' from the perspective of autistic individuals: Benefits, Limitations and Recommendations2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The Swedish Healthy Home is an innovative concept that the Swedish Energy Agency has been working on, since 2013. The purpose has been to find how technologically advanced solutions in the field of lighting can help reduce energy consumption in the Swedish homes, while improving the quality of life of the home occupants at the same time. Several lighting sensors are being proposed and tested to achieve the goal.This initiative to empower families to make healthy choices or make the right adjustment in their domestic lighting environment sounds exciting indeed, especially here in Sweden, where we have such an uneven length of days and nights during the different seasons. Nevertheless, I cannot help but wonder how such lighting controls can impact the lives of those members of the household, who may have some special needs, especially those with Autism Spectrum Disorder (ASD). These individuals comprise about 1-2% of our Country’s population [1], with more being diagnosed every year. Apart from other social and neurological issues, autistic individuals also struggle with light sensitivity, so lighting design is a key concern for them. How much flexibility and diversity can be too much in their case? On one hand, the sensory controls would give them some autonomy and the great benefit of eliminating or diming any disturbing lights, but on the other hand, many of them, especially children, often exhibit a strong aversion to change. If the lighting is too flexible, they might live in constant fear that their environment will suddenly be changed. That can throw them over the edge.This Thesis therefore attempts to understand what lighting control systems are being proposed for the Swedish Healthy Home, as well as study simultaneously the impact of lighting on autistic individuals in a domestic environment, so that conclusions can be drawn about what would work well for them and what not, if and when the Swedish Healthy Home concept is implemented. The survey is based on literature review, discussions with experts and a response to a questionnaire by 10 adult autistic subjects. The results show clearly how important it is to keep in view the special needs of the autistic section of the population also, before introducing any new light related concept on the national level.

    The Value of Light in Contemporary Memorials: Understanding the needs of contemporary memorials and how they can be accomplished with light. Proposal of a light installation for commemorating the 1989 acticommunist Revolution in Timisoara.2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The master thesis is a research about the relationship between memorials and light. It first studies the characteristics of cultural memories and tries to find what the advantages of using lighting as a means of commemoration are. The nowadays memorials are very different compared to the traditional monuments and they should include a changing narrative, treating local and universal messages. They should involve the public.A contemporary memorial is ephemeral and continuously changing- the same as light is.A series of contemporary memorials have been selected to understand the tools that makes them successful. Furthermore, it was analyzed how these parameters could be achieved through light. 12 memorials that use light as an eloquent tool have been interpreted according to certain criteria.The second part of the thesis is an applied project related to the events that happened in Timisoara, Romania, in 1989 during the anticommunist Revolution. The process of creating memorials for Timisoara is a key focus of the study. The development is equally important as the end result. It searches for the significant messages and lessons of the event. Testimonials of the participants to the revolution have been studied. Interviews and questionnaires have been developed. Following this, significant places in the city and messages were chosen. The research will conclude with a lighting installations project proposal.

    Daylight Control System For Windows: How can sun shading for individual offices be designed to prevent glare at the same time preserve daylight and a view out2018Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Daylight is an important factor to offices, but it is not utilized to its full extent today when it comes to the occupant’s comfort and well-being. A big problem with daylight is the glare that wants to be eliminated from these environments. Even if there are a vast variety of products and solutions to prevent the glare, other qualities as daylight and a view out are eliminated or reduced too. As both daylight and a view out provide significant psychological advantages for occupants in office environment, a study of existing daylight control systems and humans comfort preferences was investigated. The investigation was developed and led to a strong concept, an artefact. With the capability to preserve both daylight and a view out, even when glare is prevented. SmartFilm was found as a technique with best control over the material, when it comes to flexibility of choose from transparent to opaque. But this technique is today used more as a privacy system. With the study based on visual comfort preferences, the form and the function behind the material is interpreted differently to allow it to be a daylight control system. Studies shows that the most important characteristic of a view is its horizontal stratification and how it, by dividing the view into three layers: the sky, the city/landscape and the ground, provides with the functions we need for well-being and productivity (see chapter 2). The SmartFilms is therefore integrated in three layers on a window, allowing the user to adjust each sections opacity through a special designed device connected to the SmartFilms. By controlling each section separately, the whole window does not need to be fully covered. The daylight control system will in this way, theoretically, prevent the experienced glare, at the same time provide with daylight and a view out.

    Architecture, Home & Daylight, -The openings affection on the quality of a space2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis investigates how the opening in the envelope of a typical Swedish commercial residential project could be treated differently from today. Instead of using the openings only to create a unique facade or to reach a certain daylight factor I try to find out how the openings could be treated in a manner affecting the perception of the interior space. Conscious use of qualities related to the opening, such as daylight and view has been used as a design tool. This project is not to be seen as a traditional design project but as an investigation about daylight and openings in commercial residential architecture in Sweden today. Also the project is looking into the industry’s relation to the subject of daylight.

    Lightscape: A case study of an experience based terminology2018Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Architectural lighting design is created to serve human needs. The human needs are constantly present and evaluated in all architectural light design-disciplines, such as natural and artificial light, interior- and exterior-wise, it highlights the human response and thereof the perceived experience. The standardized terminology does not declare the human response in terms of perceived experience.

    Another field of knowledge with both scientific and experience features are acoustics, where the different features are equally present and developed when designing. The fundamental difference between light and sound is that light is perceived by the vision and sound is perceived by hearing. Also, within the field of acoustics there is a well-developed terminology used for describing the perceived experiences of sound. The experience-based terminology explains how a certain environment is understood by those who is living within it and it is called “Soundscape”. The terminology soundscape and what it entails is what the lighting industry is missing in terms of describing the perceived experience of architectural light.

    The aim with the study was to explore the perceptual experiences of spatiality and develop the ability to create an architectural lighting design and hence an experience based language.

    In this study, the concept of perceived experience of spatial light denotes attentive observed light, which all of the widened terminologies with concepts and methods implies. However, little is explained about the spatial context and thereof the coherent perceived experience in today’s standards. Standards provide a foundation for concepts to establish and be communicated across disciplines. However, by raising mutual awareness of different approaches there is a great opportunity to constantly create a living language. A living language enables possibilities when considering how to turn, twist and share ideas of what has been done before and what can be developed. The study did not only consider the creation of a living language, but it also tracks the process of translating the very abstract source of information into a physical presence, in other words the physical demonstration of a concepts meaning.

    A living language is a shared language which is created by movements that is turning ourselves to each other. By breaking through a surface, there is a possibility of reconstructing where we are collectively and we are able to have a shared language through shared experiences.

    A Light Booster metro car for the commuting work force: Human Centric Lighting in underground transportation2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    People at northern latitudes lack an effective portion of daylight, especially in winter time, to entrain their circadian rhythm. If one belongs to the group of employees who have no time for daylight exposure and are not supplied by Human Centric Lighting (HCL) in their office, the only chance to get circadian light may be the daily commute. The mega trend of urbanisation increases time of commute, with on average 20-60 minutes spent daily in public transportation in European cities. By introducing HCL to public transport, especially metro vehicles, this time frame can be used to provide the commuting work force with circadian lighting. A LIGHT BOOSTER metro car is proposed to provide the right intensity, spectral distribution, directionality and timing of light to regulate the human inner clock and support health. The LIGHT BOOSTER metro car is very efficient as light is best used due to a high person per square meter ratio. This ratio is higher than in any office building. The energy consumption equals that of an conventional single household. Besides expected health benefits, the LIGHT BOOSTER metro car works as an educative tool, raising awareness for the beneficial effects of light on human health and well-being.
