Säter M. (2010). Preferences for level of light at the work table and for the complementary ambient light. CIE proceedings. 27th session the CIE South Africa 10-15 July 2011.
The conference paper concerns subjects preferences for levels of artificial light in a given
contrast situation when staying in the indoor environment. Studies 4 and 5 were performed in the room designed for the VCT-test. The subjects got their preferences for a visually comfortable level of light at the working table and for the complementary ambient light recorded. The result shows that the subject’s preferences vary in a high extent and are almost unique. Only two pair of subjects showed the same preferences for the combination of level of light at the working table, and for the complementary ambient light.

Säter M. (2010). Colour and light and the human area for visual comfort. COLOUR AND LIGHT IN ARCHITECTURE. International conference – Venice 11-12 November 2010.
The conference paper is concerned if pattern can be seen in the subject’s preferences for room and light settings when staying in the indoor environment. The study were based on study
number 1 that was performed in room and light setting number 1, as well as in the VCT-test. The result provides a comparison between the lighting designer´s preferences for visual comfort and the subject´s preferences in the study. The room and light settings were designed close to, far from and very far from, the lighting designer’s visual preferences. The subjects appreciated to a large extent the room and light settings in the same way as the lighting designer. Low levels of ambient light made it possible for 14 of 18 measured subjects to stay within their visual
preferences for the light at the working table but not within their preferences for the ambient light.

Säter M. (2010). A holistic approach to lighting design in practical application - 2nd CIE expert symposiums on Appearance: When appearance meets lighting. 8-10 September 2010, Gent, Belgium.
The conference paper is concerned if pattern can be seen in the subject’s preferences for room and light settings when staying in the indoor environment. The study were performed in room and light setting number 1, and the in the VCT-test. It concerns the interaction of man, light, colour and space, done by the lighting designer and is based on her individual preferences. The subjects evaluated to a great extent the room and light settings in the same way as the lighting designer indicating that despite differences in preferences in visual comfort there are similarities in the response for room and light settings. A well-functioning interaction of man, light, colour and space seems to be, appreciated by the subjects in general, despite their visual preferences for level of light.

Säter M. (2010). User responses to LED as a guide for energy efficient lighting applications in Domestic Environments. Light and Engineering nr. 3 2010.
The article is concerned if pattern can be seen in the subject’s preferences for energy effective light sources when staying in the indoor environment. The article is based on study number 3 performed in room and light setting number 3 and was performed in two similar room and light settings, only different in design when it comes to light sources. The subjects preferred to stay in a room that was lit with Halogen, CFL and LED, compared to a room solely lit with LED.

Linkoping University Electronic Press 2010. New Lightings-New LEDs. Aspects on Light-emitting diodes from social and material science perspectives. Editors Mats Bladh and Mikael Syräjärvi.
The article is concerned if pattern can be seen in the subject’s preferences for energy effective light sources when staying in the indoor environment. The article is based on Study number 3 and room and light setting number 3. It concerns, data about 87 subjects, from in and outside Europe. In the study data was collected about the light sources used in the subjects´ homes. The subjects´ ability to evaluate the room lit with energy efficient light sources and predict the light source used in the luminaire was investigated. Data about the subject’s sensitivity to view lit surfaces and their evaluation of the light in the room and light settings was also collected. The study confirms that the subjects was most familiar to the light from the incandescent and found the combination of Halogen, CFL and LED as more similar to the light they had at home compared to the light emitted from LED.
PAPER VI
Säter M. (2011). User responses to Lighting Design.
The paper is concerned if pattern can be seen in the subject’s preferences for room and light settings when staying in the indoor environment. The paper is based on the first study and the interaction model number 1 and the VCT test. It provides a comparison between the lighting designers preference for visual comfort, and 18/38 unknown subjects measured values for the same experience. The study has the lighting designer’s preferences for visual comfort as a starting point for the comparison. The VCT is a neutral reference that makes a comparison between the subject’s preferences possible. The study verifies that the visual preferences vary in a high extent among the subjects. The lighting designer’s preferences for a low level of ambient light made it possible to allow 14/18 subject to find their own preferred level of light at the working table.

183 PAPER VII
Säter M. (2011). User responses to lighting design with respect to gender, personality and visual preferences.
The paper is concerned if pattern can be seen in the subject’s responses and preferences for daylight and artificial light when staying in the indoor environment. The paper is based on the second study and was performed in room and light setting number 2 with three rooms with the same interior design but with different lighting applications. Room 1 was lit with daylight only, Room 2 with a daylight mimicking artificial light, and Room 3 with artificial light deviating from daylight. The paper focuses on the formation of subgroups based on personality, gender and visual preferences for level of light and the build up of an individual light identity.

PAPER VIII
Säter M. (2011). User responses to lighting design with respect to level of alertness.
The paper is concerned if pattern can be seen in the subject’s responses and preferences for daylight and artificial light when staying in the indoor environment. The paper is based on the second study, and room and light setting number 2 developed in three rooms, with the same interior design but with different lighting applications. Room 1 was lit with daylight only, Room 2 with a daylight mimicking artificial light, and Room 3 with artificial light deviating from daylight. The study focuses on the subject’s level of alertness and is related to individual levels of hormones in the bloodstream. Submitted to: Design Studies.

Säter M. (2011). User responses to lighting design with respect to psychological experiences and hormonal release among subjects of cortisol, adrenaline, noradrenaline in the bloodstream when staying in daylight and in artificial light.
The paper is concerned if pattern can be seen in the subject’s responses and preferences for daylight and artificial light when staying in the indoor environment. The paper is based on the second study, and room and light setting number 2 developed in three rooms, with the same interior design but with different lighting applications. Room 1 was lit with daylight only, Room 2 with a daylight mimicking artificial light, and Room 3 with artificial light deviating from daylight. The study focuses on the subject’s psychological experience and hormonal release of cortisol, adrenaline and noradrenaline in the bloodstream when staying in daylight and in artificial light.

Säter M. (2012). User centred lighting design and public health.
The paper reveals a part of the literature review done in the Thesis project and is concerned lighting design linked to public health. The paper focuses on the two processes for lighting design that can be seen in use, the computer calculated lighting design process (CCLDP) and the user centred (UCLDP), the buildup of recommendations and if goals set out for light is fulfilled or not.
