Article Fulltext (PDF), pp. 1–10: In the article, we focused on the modelling of the uniformity of daylighting in a stable for dairy cows, depending on the opening structures in the roof of the building. We verified size effect of lighting openings on the daylighting in the stable. To the assessment of daylight was designed stable in which we have changed the size of the openings in the ceiling - roof construction. Ground plan dimensions and the size of the side openings remained the same. By using the program WDLS 5.0 we calculated values of daylight factor in the five possible solutions. In the first solution daylight was coming only from the sides. In the second to fifth solutions were also the upper lighting, which was ensured through the upper windows and skylight. In these solutions were changing the sizes of the upper openings. Researched points were evenly distributed over the entire stable area. From the results, we have found that for large widths are not only the side opening constructions but also the upper opening constructions. The best lighting conditions are achieved at an equally spaced upper windows and skylights.; Keywords: daylight, daylight factor in stable, opening structures, WDLS program; JEL Classification: C63
