This report has a dual focus. The first goal was to increase the knowledge of how the use of electricity in a residential building is distributed. Electricity in residential buildings is used for lighting in common areas, elevators, pumps and many other appliances. The electricity used for these different parts is to a great extent unknown. A few studies have been carried out and the result of these is referred to in this report.By means of measurements and approximations the use of electricity for various appliances became known.

One part of preventive conservation is controlling the lighting in the exhibitions. As a first step we have to accept the fact that the very act of displaying objects is causing them damage, and because the trend is for everything to be open to the public view all the time, the aim is to minimize light exposure of exhibits.This essay will present lighting options and relate them to the current recommendations. I have put the emphasis upon describing which methods one can use to minimize the degradation of exhibits on display by eliminating UV- and IR-radiation and reducing the visible light. The intention with this essay is to investigate the current lighting options and compare these to the recommendations on lighting exhibitions.The selections of different lighting options such as LED-, halogen- and energysaving lamps were made based on avaibility. Thereafter I did two types of investigations.

The master thesis deals with three completely different areas: the place, the light and the design, which all are parts of the subject landscape architecture. The Place in this paper is the graveyard, the Light is the artificial and the Design is an illumination. The common denominator is the graveyard at Galärvarvet in Stockholm, Galärvarvskyrkogården, where the three parts meet in a clear and outspoken need of new lighting. The problem formulation is: Is it possible for a graveyard to be looked upon and used as a park? How do the administrators and the designers reason in this matter and what are the consequences for example the illumination at a graveyard? This is being investigated and discussed in general and thereafter the thesis is specifically focussed on the needs and solutions for the graveyard at Galärvarvet. The thesis, which is mainly based on facts from litterature, location studies and interviews, contains of pure parts of fact, discussion parts, different types of analyses, reflections of the author, illustrations and photos from the graveyard at Galärvarvet and also a lighting proposal for the graveyard and its close environment. The purpose of this work is to show the connection between the usage of the graveyard and its illumination. All to simplify for the administrators, planners and designers. Hopefully this thesis will be of use in the deciscion making process for future lighting projects for the graveyard administration in Stockholm as a basis for their discussion and decision process for future lighting projects..

In Uppsala, Sweden, Vattenfall has a combined heat and power plant. On the premises there is an engineering workshop with old fluorescent and mercury lamps that need to be replaced. This provides a great opportunity to save energy and money by installing more efficient lighting. The main purpose of this study was to present two functional and energy efficient lighting systems including control system. The lighting systems were designed by investigating the working environment, measuring illuminance and by simulations in the software DIALux.

Det här är en text som är ett resultat av vårt examensarbete vi genomfört under den sjätte och sista terminen på scenproduktionsutbildningen på Malmö högskola. Texten och examensarbetet utgår ifrån frågeställningar som vi arbetat med under terminen i samband med att vi ljussatt två teaterföreställningar som satts upp av Teaterhögskolan i Malmös examinerande masterelever. Vi tar upp frågor och tankar om ljuset, scenrummet och ljussättarens roll i det kreativa teamet. Syftet med detta arbete har varit att utforska hur vi kan ta hjälp av ljus och ljusdesign i skapandet av scenrummet. Hur vi definierar de rum vi arbetat i och hur det är att vara en del en produktion.

Use of lighting is crucial to make public urban places available during dark hours. Landscape architects participate in planning of lighting, but during our education there is very little taught on the subject. Through this study we approach the subject of lighting by looking into lighting methods for urban plant materials during winter. In this thesis we look into ways to emphasize the visible characters and experiences of urban plants during winter season using light. Target audience are landscape architect students and landscape architects without knowledge of lighting. The part of the thesis that describe basic conditions for, and visual characters of plants can be useful to lighting designers without knowledge in this subject. Working methods used were the following: ? Pre-study about light and lighting techniques through literature and dialogues. ? Compiling important visual winter plant characters through photography and literature. ? Outdoor light experiments with plants.

This report is an inventory of the street lighting in half of the residential estates owned by Karlstad Bostads AB, a public housing company. The inventory was made to reduce the environmental impact of the street lighting. From the inventory an estimation of the total installed power and the energy consumption was made. The total estimated power of the street lighting was 125 kW and the energy consumption was 500 000 kWh/year with an estimated running time of 4 000 h/year. The dominating source of light was 125 W discharge mercury lamps.

This is a degree project that takes up history, present-day situation and analyzes these, that in turn becomes basis for cunning, both for shape and lighting, plus gives a eye-opener through entire the work. Vetlanda municipality acquires alter Stortorget that lies my in downtown. The area is not so used and has a fairly dreary appearance. Here are potential and a lot of possibilities for development. When working with a task as Vetlanda center, it is easy to take water over your head, so it is important to limit yourself. History, a description of today?s appearance and work area limit to the design proposal has been given different weight for the job.

In this study, we investigate various lighting applications in a virtual environment, where we compare between light based in naturalism (natural light) and pictorialism (artistic light). The purpose of this study is to gain further knowledge in lighting, which is increasingly important for game graphics. Theory are examined to gather information and recommendations on how to use various light settings that convey different emotions. We then use this information to illuminate the environment that we have built. The environment is presented in Unreal 4 for respondents who are allowed to move around freely in the environment.

The main aim of this master thesis was to examine the visual ergonomics and the systematic work environment management concerning lighting issues for nurses within domiciliary care. Further aims were to examine a few existing lighting solutions, to come up with ideas for future possible lighting solutions, and to evaluate if the legal regulations for lighting is satisfying and if the regulations are obeyed in domiciliary nursing.The methods used were a questionnaire completed by 55 nurses, field studies of used lightings in cooperation with a student in industrial esign, test of ten existing lighting solutions in a laboratory environment, and a field test of five existing lighting solutions tested by nine nurses in the home of the patient.The result indicates that 40 % of the asked nurses were dissatisfied with the working light in the patient?s homes. All respondents reported poor working light close to the patient, 50 % reported that this problem occurred daily. One third reported that they had to work in uncomfortable working postures due to insufficient working light, and 15 % reported risk of making mistakes due to the same reason.

During our education to become Lighting designers at Jönköping University, the artificial lighting has been in focus. Therefore we wanted to learn more about daylight. We chose to do this from a visual approach in open plan offices. Since daylight is part of the architects´ responsibility to master, we wanted to examine what architects think of when they plan daylight environments in open plan offices and how this is expressed in the buildings with focus on the visual factors.Our questions at issue are:What knowledge do architects have concerning daylight planning, and how do they use this knowledge in their practice?How well do the chosen daylight environments meet the end-users need of a good visual environment? The study consists of three case studies, carried out in the same way.

This project measures the upper bound of exposure time for laser reflection detection in the software DotDetector. Via measurement of the exposure time for which distortion happens in a room lit with everyday light we conclude that the upper bound for exposure times are 100 milliseconds. This value does not change as long as the lighting in the room is the same. As future work this project proposes variable upper bounds depending on secondary lighting in the room. Also we propose automating the colour masking of the detection algorithm..

The background to this report is based on how architectural art through timesbeen treating daylight with greatest precision to take advantage of its good quality,and how the technical revolution with artificial lighting affects our way of workingwith daylighting today.The purpose of the study is to contribute to the knowledge how the daylightopening affects the perception of a room. The aim is to clarify how proportionsand placement affects how the incident light occurs in the room and how thataffects on how the room is perceived. The study is meant to be used by lightingplanners, and in terms of pleasantness, be able to create the best possible daylightenvironment..

Tylö AB is the leading manufactor of sauna cabins in Europe, but there is a lack of a sauna lightning produced by Tylö. The project of developing a new sauna lightning series was assigned two students at the developmentengineering program at Halmstad University. The main problem with lightning in the sauna is the heat and security aspect. The selection fell on LED technology as the lightning source, thanks to its small measures and low heat emission. The work of constructing of a lightning armature which the capability of cooling down the LED lightning was carried out during autumn ?06 and spring ?07.
