In this thesis, taking into account the minimum requirements of regulations and standards that address lighting of residential premises with daylight, software DIALux was used to analyze the impact of glazing inclination on the illuminance of a hypothetical space (average illuminance, daylight factor DF, illumination uniformity ratio U0). For each window inclination, illuminance was calculated for three different orientations (N, S, E) and three sky types (CIE Clear, Averaged Intermediate and Overcast). Furthermore, we have determined with an accuracy of ± 0.10 percentage points, the appropriate glazing area for each window inclination that results in equivalent illuminance as in the case of the baseline. By analizing the simulation results, we have shown that in order to achieve a sufficient level of illumination, roof window openings do not require such large areas as vertically positioned ones. To optimize the Rules on Minimum Technical Requirements for the Construction of Residential Buildings and Dwellings, we propose requirements that would separately take into account
the impact of vertical and roof glazing.
