The impact of material solution of cover shells on stable daylight. Light is supplied to the stable via a roof skylight, where wired glass is the infill of skylight structure, through open side walls, whereby the influx of light on one side is influenced by the shelter, and through the open gates, which are located in the front walls of the stable were assessed. Measurements of light intensity inside the stable were carried out in two height levels. Simultaneously, measurements were performed outside, on non-shadowed plane. Daylight factor was calculated from the measured values of internal and external comparative illuminance. Resulting values were processed into tables and graphs. The roof skylight has clearly the greatest influence on the lighting of the stable. Its disadvantage is that the stable overheats in these places in summer. Here, it would be appropriate to replace the fill of the skylight with translucent light elements.
