Ljusnivåer i butiksmiljö med fokus på visuell upplevelse

Sammanfattning: The study examines the light level's influence on the visual experience in a clothing store. The survey should, with empirical data and theory, contribute to increased knowledge of the level of light in store environments. The question that the study answers is "How does the visual experience of a store change when the light level changes?" Based on previous studies and own observations, stores have relatively high visual light levels. The room experience of a store is influenced by various factors such as interior design, materials, colors and design, and our senses. Several studies have shown that the visual conditions for our experience have a strong impact on the stay in a store. The survey is based on field observations in existing stores located in Jönköping's shopping center, Asecs. A field observation was performed to gather information and create an idea of what visual light levels and physical aspects such as the illuminance are present in today's stores. The stores design, materials and surface colors were documented. With the support of the field observation results and standards from Ljus & Rum (2013), an experiment was designed to mimic a store environment in order to be able to evaluate and study the light level's influence on the visual experience. The 16 participants had to evaluate three different light scenes with the average illuminances of 300 lux, 700 lux and 2700 lux. The evaluation was performed by using a psychological instrument from a well-proven method, BELUPP. The results of the experiment show that the participants preferred 700 lux, which is not fully in line with the generally recommended 300 lux for stores. The results show that in the planning of lighting, the light level, distribution and character should interact to create a light environment with a pleasant visual experience. Higher light levels are more acceptable in rooms with darker surface colors and materials. Light levels are a significant factor in retail environments and have a major impact on ecological, social and economic sustainability. Lighting in the shop should be adapted to the situation as there are a number of factors that affect the perceived light level.
