V diplomski nalogi sem s pomočjo programa Rhinoceros in programskega vtičnika ClimateStudio analizirala osvetljenost odprtega pisarniškega prostora. Analizirala sem vpliv velikosti in oblike okenskih odprtin na osvetljenost prostora. V nalogi so obravnavane štiri velikosti okenskih odprtin s tremi različnimi tipi zasteklitev, in sicer z dvoslojno, troslojno in solarno zaščitno zasteklitvijo. Pridobljene rezultate sem primerjala z vrednostmi iz pravilnikov in standardov in preverila, ali je v prostoru dosežena ciljna vrednost faktorja dnevne svetlobe, ki je potrebna za opravljanje določenih delovnih nalog. Poleg osvetljenosti prostora pa sem analizirala tudi možnost pojava bleščanja. Ugotovila sem, da se s povečanjem velikosti okenskih odprtin izboljša osvetljenost prostora z dnevno svetlobo, hkrati pa se poveča tudi možnost pojava motečega bleščanja. Bleščanje je najbolj moteče v spomladanskih in jesenskih mesecih okoli 12. ure, ko je sonce najvišje na nebu. Najbolj kritična so mesta v bližini okenske odprtine s pogledom proti oknu. V določeni meri lahko moteče bleščanje zmanjšamo z uporabo ustreznega tipa zasteklitve, in sicer tistega z manjšo prepustnostjo svetlobe. Delež ur nevzdržnega bleščanja se je namreč v primeru večje odprtine s solarno zaščitnim tipom zasteklitve zmanjšal za 50 % glede na delež ur pri dvoslojnem tipu zasteklitve in enaki površini zasteklitve.

• Title: The influence of window design on the daylighting and glare occurrence in indoor environment : graduation thesis no.:411/B-GR

Abstract

In my thesis I analysed the illuminance of an open office space using software Rhinoceros and the ClimateStudio plug-in. I analysed the effect of the size and shape of window openings on the illuminance of a room. The thesis deals with four sizes of window openings with three different types of glazing, double pane glazing, triple pane glazing and solar control glazing. I compared the results with the values in the regulations and standards to check whether the target daylight factor required for the specific work tasks was achieved in the room. In addition, I also analysed glare probability. I have found that increasing the size of window openings improves the daylighting of a room, but also increases the chance of disturbing glare. Glare is the most disturbing in the spring and autumn months around noon, when the sun is highest in the sky. The most critical positions are near window openings with views facing to the window. To a certain extent, the occurance of disturbing glare can be reduced by using the right type of glazing with lower light transmission. In fact, the percent share of hours of intolerable glare was reduced by 50 %, when I used larger opening with solar control glazing compared to when I used double glazing with the same area of glazing.
