20.500.12556/RUL-142801 Vpliv rosenja na hladilni učinek ozelenjenih gradnikov stavb Influence of dew water on the cooling potential of green building structures Magistrsko delo obravnava vpliv kondenzirane vlage iz zraka na hladilni učinek ozelenjenih gradnikov stavb. Poleg kondenzacije vodne pare na vegetaciji zelene strehe smo obravnavali tudi kondenzacijo zračne vlage v nočnem času na namenskih zbiralnikih rose. V delu smo uporabili dve metodi izračuna količine kondenzirane vlage. V programskem okolju Excel smo postavili empirični model ter izdelali numerični model ter njuno ustreznost pri napovedi količine kondenzirane vlage preverili z meritvami v naravnem okolju. V nadaljevanju smo predvsem z numeričnim modelom, ki se je izkazal kot ustrezen, izvedli numerično analizo količine rose za kraje z različnimi podnebnimi značilnostmi. Rezultati meritev so pokazali, da količina kondenzirane vlage, zbrana v posamezni noči, ni presegala 0,2 mm m-2 dan-1, tako na zeleni strehi kot na namenskem zbiralniku, kar predstavlja le 1/3 teoretične možne količine po literaturi. Numerična analiza je pokazala, da znaša letna količina kondenzirane vlage na zeleni strehi v Ljubljani 11,3 l m-2 leto-1, kar predstavlja le 1 % letnih padavin. Približno enak delež, 1%, smo izračunali tudi za Berlin in Barcelono. Izračunana količina kondenzirane vlage tako nima vidnejšega vpliva na hladilni učinek zelenih streh ali zmanjšanje potrebne količine vode za namakanje vegetacije. This master thesis deals with the influence of the dew on the cooling effect of green building structures. In addition to the condensation of water vapor on vegetation of a green roof, we also analysed condensation of of water vapor in the night time on dedicated dew condensers. In the thesis we used two methods of calculating dew amount. We set up an empirical model and created a numerical model in Excel software environment and checked their adequacy in predicting the amount of condensed moisture with in-situ experiments. Afterwards, we carried out a numerical analysis of the amount of dew for places with different climatic characteristics, mainly using a numerical model, that proved to be more adequate. Results from the measurement showed, that the amount of dew condensed in a single night never exceeded 0,2 mm m-2 day-1, both on the green roof and on the dedicated collector, which represents only 1/3 of the theoretically possible amount according to the literature. Numerical analysis showed, that the annual amount of condensed moisture on the green roof in Ljubljana is 11,3 mm m-2 year-1, which represents only 1 % of the annual precipitation. Approximately the same share, 1 %, was also calculated for Berlin and Barcelona. The calculated amount of condensed moisture thus has no visible effect on the cooling effect of green roofs or the reduction of the required amount of water for irrigating the vegetation. ozelenjene strehe kondenzacija zračne vlage vodna bilanca meritve v naravnem okolju evapotranspiracija green roofs condensation of vapour water balance in-situ experiments evapotranspiration true false false [G.
