Lighting Quality of Indoor Environment in Large Floor Buildings in Light Industry

The paper highlights the problems associated with the application of daylight and integral lighting in industrial facilities. In the case study of a multi-storey textile plant, we show how combined lighting (daylight and integral illumination) can be evaluated in production halls labelled F and G. These halls have large areas 54 x 54 metres, and are more than 5 meters high. There is daylight only on side through connected windows in a vertical position. In this paper we want to present case studies of these two production halls in the textile factory located in Kosice (Slovakia). These are halls that are lit through by daylight from two sides through external walls that are opposite or next to each other. The results of the case studies can be applied in similar production halls illuminated by a “bilateral” —a double-side daylight system and natural illumination through windows on two sides in a vertical position. Such a situation is typical of multi-storey buildings in light industry. The proposed approach of daylight factor calculation can also be applied to floor space in other similar buildings.
