The concept of visiting a restaurant is no longer related to the consumption of a food. The total process of visiting a restaurant became a pleasant experience to elevate mood and satisfaction and create a memorable experience. In this thesis, we aim to case study three restaurants of the same brand using quantitative and qualitative measurements such as questionnaire, V/P theory, and measurements. Moreover, the results of the assessments will be used to investigate how lighting can improve the dining experience in the restaurant while taking into consideration reducing energy consumption. The results of the quantitative and qualitative analysis indicated the lighting in each of these restaurants differs from each other, and they require a redesign to enhance customer satisfaction and to be more energy efficient. The thesis presented a lighting solution which considers all the relevant factors for customer satisfaction from literature and standards. The solution can improve the customer experience in the restaurant and advance its compliance with the sustainability goals.

This thesis concentrates on lighting preferencesin living rooms concerning Nordic lightqualities in winter. Living rooms are spaceswhere we relax, communicate, eat, gather andread.

In the Nordic countries, where thelight and darkness change dramatically betweenthe seasons, the transitions have a specialsignificance.

Additionally, paintings from differentseasons help me to understand awareness oflocal daylight and attention of participants.Results show us that the attention people giveto the desired light intensity and colors aremore related to the people’s interests than totheir background, profession and length ofstay in Stockholm. It would be interesting toinvestigate this topic with more people who livein Stockholm more than five years.The concentration of the thesis is understandinghow local daylight conditions can affect people’slighting preferences in their living room.Results will help us to implement the knowledgeand collected information into the lightingdesign process in living rooms in Nordic countries.
