Article Fulltext (PDF), pp. 61–67: The proper lighting in the stable is for the health, as well as for the usefulness of dairy cattle very important. In the stable we can assess the lighting by the measurement or by the simulation in an appropriate program. The advantage of simulation is that we are not dependent on the weather conditions, in which is daylighting variable. In this work we simulated the same two stables with different sizes of opening structures in the longitudinal walls. Using a computer program Wdls 5.0 we calculated the values of daylight factor. These values we compared in the selected profiles and rows by the tables and graphs. We have found that the opening of the side walls will improve the light conditions in the stable, but with such stable width do not affect the lighting in the middle of the stable. We can to improve conditions in a stable from overheating by change the technological arrangement and simultaneously we can design of such illuminating elements in skylight through which we achieve the smallest overheating of stable.; Keywords: lighting simulation, program Wdls 5.0, stable, daylight factor; JEL Classification: C 63
