Article Fulltext (PDF), pp. 67–74: The contribution is aimed at the comparison of daylighting in the original and reconstructed housing buildings. On the basis of the measurements of daylighting we calculated the values of the daylight factor in both stables. The distribution of the measuring points in the stables was different. In the original stable were two rows of measuring points, in the reconstructed stable were four rows of measuring points. The course of lighting at the measuring points was shown in program Excel using graphs. The values of the daylight factor were compared in each row in both stables using Scheffe′s test (ANOVA) and box-plot. The results show that lighting in the reconstructed building has increased significantly. The statistical analysis of the results showed that significant difference is not between the rows in which the illuminance measured (P > 0.05) in spite of assumption the lighting under the skylight will certainly be higher. This is caused especially inappropriately selected measuring points. There are in reconstructed stable significant differences in illuminance between the rows, that were under the skylight and rows that were located near the open side walls (P < 0.05). Daylighting is significantly higher under the skylight (P > 0.05).; Keywords: university, input-output analysis, multiplier effects, regional multiplier; JEL Classification: R15, R12, O15
