Abstract

V diplomski nalogi sem obravnavala vpliv različnih tipov senčil na osvetljenost izbranega prostora z dnevno svetlobo. V uvodu je opisana problematika, ki se navezuje na pojem naravne svetlobe, njen vpliv na človeški vizualni zaznavni mehanizem ter racionalno rabo energije. V prvem delu diplomske naloge je predstavljena literatura, ki opisuje osvetljenost prostora z dnevno svetlobo in različne vrste senčil. V nadaljevanju je določen testni pisarniški prostor in izbor senčil za izvedbo nadaljnje analize. Za izvedbo analize v drugem delu diplomske naloge sta določeni dve skupini senčil, in sicer fiksna in premična senčila. Pri fiksnih senčilih je izvedena analiza za vertikalne in horizontalne izzidke, notranjo in zunanjo svetlobno polico, brisoleje s horizontalnimi ali z vertikalnimi lamelami in nadstrešek z lamelami. Pri premičnih senčilih je analiza izvedena za rolete, žaluzije in senčilo sonro. Na podlagi pridobljenih rezultatov analize je izvedena primerjava količnika dnevne svetlobe in povprečne osvetljenosti prostora za določene tipe senčil na tri kritične dni v letu pri treh tipičnih orientacijah. Prav tako je izvedena primerjava s predhodno določenimi vrednostmi osvetljenosti oziroma preverjeno je upoštevanje minimalnih zahtev iz pravilnikov in standardov, ki obravnavajo osvetljevanje z dnevno svetlobo. Ugotovila sem, da imajo analizirani tipi senčil zelo različen vpliv na osvetljenost izbranega prostora in da je za pravilen izbor potrebno upoštevati številne parametre. Za fiksna senčila velja, da le-ta vplivajo na osvetljenost prostora skozi celotno leto, kar se v določeni meri izkaže za slabost, medtem ko se s primerno regulacijo premičnih senčil lažje zagotovi ustrezne vizualne razmere v prostoru čez celotno leto. Senčila z lamelami (razen senčila sonro) se izkažejo za primernejša z vidika doseganja vizualnih kriterijev glede na rezultate ostalih analiziranih tipov senčil, saj se da s primernim kotom lamel lažje uravnavati dnevno svetlobo, ki vstopi v prostor.

Secondary title: Influence of shading devices on illuminance of indoor spaces
Secondary abstract: This paper is trying to define glazing type of school classrooms in order to achieve optimum energy performance and visual conditions. We analyzed and evaluated effects of orientation, glazing size and its properties, overhangs mounted on various heights and simple sensor controlled shading. Based on the results of the analysis we generated instructions for glazing design for primary schools for the central region of Slovenia in order to achieve optimum energy and visual efficiency of a classroom. In this thesis, I analyzed the influence of different types of shading devices on the illuminance with daylight of the selected indoor space. The introduction describes the problem which relates to the concept of natural light, its impact on the human visual perceptual mechanism and a rational use of energy. The first part of the thesis presents the literature describing the illumination of the space with natural daylight and different types of shading devices. The following part defines the test office space and the choice of shading devices needed for the accomplishment of the further analysis. For the analysis in the second part of the thesis, two groups of shading devices are defined, these being fixed and movable shading devices. In the case of fixed shading devices, the analysis is made for vertical fins, horizontal overhangs, indoor and outdoor light shelf, sun breakers with horizontal or vertical louvres as well as for a jutting roof with louvres. As for movable shading devices, the analysis is made for shutters, blinds and a shading device named sonro. Based on the acquired results of the analysis, the comparison of the daylight coefficient and the average illuminance of the indoor space for particular types of shading devices on three critical days of the year in case of three typical orientations is made. Moreover, a comparison with pre-defined illumination requirements is made and a compliance with the minimum requirements of regulations and standards related to lighting with daylight is verified. I found out that the analyzed types of shading devices have a very different impact on the illuminance of the indoor space and that for a correct choice, it is necessary to take into consideration a number of parameters. Fixed shading devices have influence on the illuminance of the indoor space throughout the entire year, which to some extent is a weakness, while a proper regulation of movable shading devices enables an easier way to get proper visual conditions in the indoor space throughout the year. According to the results of other analyzed types of shading devices, shading devices with louvres (excluding sonro) are better in terms of achieving visual criteria, because with a proper angle of louvres, it is easier to control the daylight that enters the indoor space.
