Dagsljusdesign för en god visuell miljö

Sammanfattning: During our education to become lighting designers at Jönköping University, the artificial lighting has been in focus. Therefore we wanted to learn more about daylight. We chose to do this from a visual approach in open plan offices. Since daylight is part of the architects´ responsibility to master, we wanted to examine what architects think of when they plan daylight environments in open plan offices and how this is expressed in the buildings with focus on the visual factors. Our questions at issue are: What knowledge do architects have concerning daylight planning, and how do they use this knowledge in their practice? How well do the chosen daylight environments meet the end-users need of a good visual environment? The study consists of three case studies, carried out in the same way. Each case study contains an analysis of the daylight environment in a modern building with open plan offices. A responsible architect was interviewed about the intensions for the building, and about his or her general thoughts about daylight. Three end-users were also interviewed about their experiences of their working environment and the daylight conditions in each building. In total three buildings were analysed, three architects and nine end-users were interviewed. The result shows that it is hard to tell what knowledge architects have about daylight, since it is a part of the overall design of the building. It is also very individual whether the architect displays an interest, and work with daylight issues in an active way. We can see differences in this matter between the interviewed architects. The analysed buildings also show varying results in the visual qualities. The results from our environment analyses are at most part confirmed by the end-users in each building. The problems we have found concerning the daylight environment are primarily the solar shadings and the layout of furnishing. Our conclusion is that architects could benefit from collaboration with lighting designers in daylight issues. This is because lighting designers have more knowledge about the visual conditions of the eye, and a more explicit focus on the end-user. To ensure a good collaboration the lighting designers also need to increase their knowledge about daylight in buildings, and about the building construction as a whole.
