Visuellt tillfredställande ljusmiljöer vid nyplanerad belysning på utvalda sjukhusavdelningar

Sammanfattning: Abstract The purpose with the report is to contribute with information around how to shape a lighting environment that support well-being. The goal is to show builders that the Swedish lighting standard SS-EN 12464-1 ​Ljus och belysning ​can be fulfilled in a more visually satisfactory manner. ​The study includes general areas of newly built and reconstructed hospitals. Observations at the hospitals take place during the day and do not take the weather into account. ​Builders for different types of projects are interviewed to get an understanding of how lighting design is handled in the construction process. The thesis has qualitative methodology where previous research forms the basis for the work, supplemented with observations and interviews. Collection of research on well-being and light environment is the first step in the work. Thereafter two hospitals are observed. Conclusions drawn from previous research and observations are used to make interview questions to the builders. Research shows that a satisfactory light environment that promotes well-being is an interplay that forms an ensemble of several factors where light is one of the factors together with architecture, air, sound, furnishing, color, and opportunity for outlook from windows as well as daylight. The two hospitals that have been observed follow to some extent what research shows how light environments should be designed after well-being. Builders think that lighting is an important part of a building and should come in at an early stage. Generally, the builder's does not possess any expertise in the area, thus taking expert assistance for best results. The builders who responded to the interviews in the projects had a basic requirement following the Swedish lighting standard SS-EN 12464-1. ​It is shown that visually satisfactory light environments that promote well-being can partly be created with Swedish lighting standard SS-EN 12464-1. Provided that a lighting designer comes in early in the construction process and may depart from the standard if necessary to create interaction with the other factors in the room that are adapted to human perception.
