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.

During the 1930´s the hot potato for the Swedish lighting associations were how to create the most suitable light for every situation, either for industries, offices or homes. The light bulb were the most frequently used source of light but due to limitied luminous intensity, big halls sometimes required up to hundreds of light bulbs to produce the right amount of light. Two kinds of different lights, by different reasons, can be titled the predecessors of the fluorescent lighting during the 1930´s: The volfram-filament tube light due to its estetic similarities and the electric discharge (mercury- and sodium-) lamps due to its technical resemblance. Even though they came in quite wide use (the volfram tube in public halls (e. g.

AbstractDelta Terminal owns an outdated industrial building which they now rent out to businesses. This property currently has a high energy con-sumption and therfore it is desirable to improve the efficiency. In ordet to reduce the energy consumption within the industrial building enve-lope, the heating systems and lighting are being investegated. A good building envelope emits less heat and thus reduces the energy consump-tion. An energy audit is a tool used to determine the energy loss.

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.

Bright Chest of DrawersThis project derives from a fascination of spaces which withonly light and shadow withhold a narrative value, which createsemotions and experiences with a minimum of objects. Iwanted to invesitigate light and lighting, and create a productthat can change the mood and experience of a spatial enviromentwith light. Questions I asked myself was: How do I relateto the spatial limitations that arise? How can I, with light asmy tool, give form to an immaterial value or state of mind?Will the object that illuminates be the most important factorof communication and meaning when I want to tell a story, oris it the light itself?The result became a chest of drawers that is lighted up frominside when you open the drawers. It serves a function as a unitfor storage of objects, but also makes us reflect of the importanceof objects, of how we define a spatial enviroment, andwhat we consider as private spaces in our home..

Ljusförorening är ett relativt modernt fenomen som allt mer påverkar tillgången till en stjärnklar natthimmel. Det finns en mängd olika internationella organisationer som arbetar för att minska ljusföroreningar och för att bevara natthimlens synlighet, bland andra International Dark-Sky Association, Royal Astronomical Society of Canada och Starlight Initiative. I den här uppsatsen undersöker jag ett antal strategiska dokument genom textanalys, för att analysera deras huvudsakliga motiv till förändringar och för att få en överblick över vilka sorters åtgärder som dessa organisationer föreslår. De analyserade dokumenten är Astrolabs Practical Guide for Lighting, Dark Sky Societys Guidelines for Good Exterior Lighting Plans, International Dark-Sky Associations Practical Guide, Royal Astronomical Society of Canadas Dark Sky Guidelines, Patersons Sark ? Dark Sky Island Lighting Management Plan, Flagstaff Dark Skies Coalitions Lighting Tips, Starlight Initiatives Defence of the Night Sky and the Right to Starlight och Narisda och Schreuders Light Pollution Handbook.

In this thesis is studied the electrical load of Paradisskolan with respect to power quality and energy consumption. The school's owner Trollhättans Tomt AB is also interested to know if they can reduce their costs by changing to smaller meter fuses. A recurring ground fault that?s been recorded from powerpanel A1A has been investigated. The school's equipped with an electrical bonding system, harmonic filters for the third harmonic currents, TN-S system from feeding transformer and groundfault monitoring.

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.

The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.

Det kommande innehållet i detta examensarbete kommer att handla om min frågeställning som berör integrering av 3D objekt i en verklig miljö: ?Vad finns det för metoder att integrera 3D objekt med en verklig miljö och hur gör man??.Arbetet och efterforskningen har utförts i Söderhamn, där jag har arbetet hos 3D animationsföretaget Magoo 3D Studios. Med hjälp av anställda på Magoo har jag genomfört experiment för att själv prova på de olika metoder som ska kunna besvara min frågeställning.Som resultat så har jag kommit fram till att alla divisioner inom 3D, som modellering, texturering, ljussättning och compositing kan bidra till realistisk integrering på sitt eget vis, dock i olika utsträckningar. Mina experiment har alla varit lyckade och jag känner att de är på rätt väg mot fotorealistiska resultat.I slutändan så upplever jag att de metoder som bidrar mest till en realistisk integrering är en bra ljussättning med en Image Based Lighting metod, samt att ha bra vetskap om hur en kamera fungerar för att sedan kunna efterlikna dess typiska drag samt artefakter så bra som möjligt.Kombinerar man dessa metoder så är man en bra bit in på vägen till fotorealism där man inte längre är säker på om datorgenererade bilder är riktiga eller inte..

Efficient energy use in restaurantsUmeå Municipality wishes to combine energy issues with food control, and thus help restaurants to become more energy efficient. During March and April 2010, I visited seven restaurants and interviewed restaurant personnel about current state and application of kitchen appliances, using a checklist to make sure that the same questions were asked at all restaurants. The restaurants were all different sizes and offered different kinds of food. The study mostly focuses on energy efficiency by behaviour and not on location or technology. Almost every restaurant that was visited had the potential to improve in one or more areas, such as kitchen appliances, lamps and lighting fixtures, heating, cooling and ventilation.

Today's communication solution between the vehicle and trailer is one many see as anon-viable solution, then breakdowns on both the lights and cables are common. Now, anew innovation enters the market, a system that can transmit wireless control signalsbetween the vehicle and trailer.Parvus and Zap, the two solutions that the projekt group has come up with during thisthesis work carried out over the last year on Utvecklingsingenjörsprogrammet.Technologists Peter Jägevall and Christopher Åberg has developed this project on theirown. The group has developed various concepts and chosen to work on, two of them.The project has resulted in this report and a prototypeThe solution that the group has developed is a wireless communication between vehicleand trailer. The project team has developed new power-efficient LED lighting fixtures inorder to implement an internal power source in the trailer. The result of this has becomea maintenance-free and wireless product to trailers.

This thesis includes an energy survey of the Herrgården pre-school, which has a modern heating- and ventilation system, and a comparison with Östers pre-school which has an older system. An energy survey of Östers pre-school has already been done by a group of three students and all the calculations and values have been collected from that survey. As of today, both pre-schools are heated thru district heating. It will be much easier to make smart and feasible energy-saving-measures by first conducting the energy survey.Herrgården pre-school in Gävle houses 81 children, therteen teachers, one cleaner and one cook. It was finished in the middle of 2009 and the staff has been very pleased with the in-door climate.
