Abstract [en]

This study is the first to evaluate the different criteria presently used in Sweden for lighting design, and their importance when planning the visual environment. It considers the role of the Swedish lighting designer and the different evaluations of criteria in the office lighting design process. The study aims to investigate whether a designer with an academic education or longer experience would infer more value in perceptual criteria and incorporate research into designs to a larger extent than a designer with less education. The findings suggest that current research needs to be more readily available to practitioners to enhance differentiation of criteria and proposed lighting designs. Education and experience could not be proven to make a difference, but different gender brought with it a divergence in the evaluations.

Abstract [en]

This thesis is concerned with the design of the artificially lighted environment in computerised offices. Its aim is to describe which kind of lighting solution is best suited to accommodate VDT-based tasks, and whether or not working in front of a VDT affects visual comfort and well-being. The research question has been approached in four studies: 1) A questionnaire study aimed to establish how different criteria are used in the office lighting design process. 2) An experimental study comparing the influence of different office light settings on perceptions. 3) A comparison of an LED light setting with a conventional light setting. 4) The final study retrieved articles describing research related to office lighting, and resulted in a state-of-the-art article in office lighting research. The findings show that there is a need for lighting education within the group of lighting practitioners, as well as for research that is accessible and applicable to lighting designs. The experimental studies could not verify that office lighting affects performance, even though it was shown that a varied light setting was perceived to enhance well-being more than a monotonous lighting solution. One important contribution in this thesis is the unfolding of the inadequacy of the methodology used in current lighting research. It is shown that quantitative measures alone cannot explain the complex interactions between human perceptions, well-being, visual comfort and performance.

Abstract [sv]

Avhandlingen handlar om hur ljusmiljön på datoriserade kontor bör designas för att bäst stödja datorbaserat arbete. Eventuell inverkan av bildskärmen på visuell komfort och det allmänna välbefinnandet studeras i fyra studier: 1) Enkätstudie som syftar till att kartlägga hur olika kriterier används i ljusmiljöns designprocess. 2)Experimentell studie som jämför påverkan av ljusmiljön på olika perceptioner. 3) Jämförelse mellan upplevelsen av en ljusmiljö med LED-ljuskällor och en med konventionella ljuskällor 4) Genomgång av tidigare forskningsstudier inom området. Resultatet visar att det finns ett utbildningsbehov bland yrkesverksamma ljusdesigners, men även att det finns ett behov av forskning som är lätttillgänglig och applicerbar på ljusdesign. De experimentella studierna kunde inte bekräfta att ljusmiljön påverkar prestationen, även om det visades att en varierad ljusdesign uppfattades stödja välmående mer än en monoton ljusdesign. Ett viktigt bidrag med denna avhandling är att visa på oförmågan hos kvantitativa metoder att ensamma förklara de komplexa samband som finns mellan upplevelse, välmående, visuell komfort och prestation.

Abstract [en]

This paper presents an experimental study with 47 participants on the influence of lighting on performance and well-being in an office environment. Well-being, alertness and performance were evaluated and measured in two rooms with artificial lighting and one room with day lighting. The evaluations were correlated to cortisol/melatonin saliva samples, illuminance and spectral compo-sition of the lighting. The results show day lighting to have a sustained influence on alertness and performance and it is furthermore concluded that the level of cortisol in saliva was not influenced by the illuminance and did not have an influence on performance. The participants preferred a lighting with different kinds of light sources to a more neutral lightning and gave it higher ratings for well-being.The analysis shows that comfort did not influence alertness.
