Daytime Lighting Assessment in Textile Factories Using Connected Windows in Slovakia: A Case Study

Abstract

This paper highlights the problems that are associated with daylight use in industrial facilities. In a case study of a multi-story textile factory, we report how to evaluate daylight (as part of integral light) in the production halls marked F and G. This study follows the article in the Buildings journal, where Hall E was evaluated (unilateral daylight). These two additional halls have large areas that are 54 × 54 m and are more than five meters high. The daylight is only on the side through the attached windows in envelope structures in the vertical position on the hall. In this paper, we want to present two case studies of these two production halls in a textile factory in the eastern part of Slovakia. These are halls that are illuminated by daylight from two sides through exterior peripheral walls that are against or next to each other. The results of the case studies can be applied in similar production halls illuminated by a "double-sided" (bilateral) daylight system. This means that they are illuminated by natural illumination through windows on two sides in a vertical position. Such a situation is typical for multi-storied industrial buildings. The proposed approximate calculation method for the daylight factor can be used to predict the daylight in similar spaces in other similar buildings.

Visual Comfort Assessment in an Industrial Environment: A Case Study

“…Too high brightness contrasts your eyesight. High reflectivity floors have an adverse effect on brightness distribution [17]. The current visual comfort system is mostly focused on office buildings.…”

“…The current visual comfort system is mostly focused on office buildings. However, there is limited knowledge about daylight quality and visual well-being in industrial work environments [17][18][19]. Industrial lighting is currently at a level that in many cases does not meet the requirements of legislation and standards.…”

“…Industrial lighting is currently at a level that in many cases does not meet the requirements of legislation and standards. Slovakia has historically had a high energy-intensive industry structure, and its industry structure is dominated by the engineering industry [17][18][19].…”
