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.

“…LiFi, the Internet of Things, Power over Ethernet, and wireless sensors have transformed the traditional luminaires into smart devices capable of connecting to a network transmitting information [4]. As the light is enriched now with information, it is therefore possible not only to increase energy savings through controls [5][6][7][8][9][10][11] but also to include additional functions such as the ability to adjust the lighting system's operation according to the users' expectations and needs [12][13][14]. The aforementioned developments allowed not only the control of luminaire's emitted luminous flux but also the color temperature of the light source, thereby mimicking the daily change of daylight.…”

The quality of visual comfort has always been an essential element considering human comfort. Providing visual comfort in a living environment reduces the need for artificial lighting, which subsequently has a direct relationship with energy consumptions and its expenses. Besides, the maximum possible usage of daylight instead of artificial lighting significantly contributes to providing a favourable condition in terms of visual comfort for the residents. This essential factor is manifested in public spaces, such as libraries that are associated with students and the quality of their study time. The main aim of this paper is to provide applied solutions to use more natural lighting strategies as an alternative for artificial lighting, which helps to reduce electric energy consumption while providing visual comfort for users. The role of architectural elements, such as the position and dimensions of the windows, reflectivity of materials, layout of surfaces, and appropriateness of space in line with the objectives as mentioned earlier are examined thoroughly. For this purpose, literature studies, as well as computer simulations via Relux software, are utilized to investigate the set research objectives. Finally, the simulation results suggest that the best orientation to achieve the optimal model using daylight in study spaces is northernsouthern orientation. In addition, using windows with maximum height in the middle of the transverse front of buildings with window to wall ratio of 35 to 45 percent along the vertical and horizontal divisions (grid) is suitable for such places. Design criteria include the higher access to daylight, visual comfort, and reduction of electrical energy consumption. The reflectivity coefficients for roof materials, floor, and walls are 0.6, 0.4, 0.4, and 0.6, respectively, and transparency for windows is 80%. The obtained results also suggest the length-to-width ratio and height-to-width ratio are 6-to-5 while horizontal and vertical surfaces in near windows and in middle space along the longitudinal direction are optimal for research purposes.
