20.500.12556/RUL-94938 Energijska in ekonomska smiselnost izvedbe ukrepov v stari poslovni stavbi Energetic and Economic Advisability of Implementing Measures for the Old Office Building Evropska unija se je zaradi vse večjega problema z onesnaževanjem okolja zavezala, da bo zmanjšala količino emisij toplogrednih plinov. Velika količina le teh je proizvedena zaradi neučinkovite rabe energije. Tudi Slovenija si kot članica EU prizadeva za zmanjšanje celotne rabe energije. Zaradi tega smo si za diplomsko nalogo izbrali poslovno stavbo, za katero smo s pomočjo programov DesignBuilder in EnergyPlus izračunali potrebno moč hladilnega agregata, korist njegove potencialne zamenjave z novim agregatom in preračunali ukrepe za zmanjšanje celotne rabe energije. V drugem poglavju smo izvedli tri ukrepe, katerih energijsko in ekonomsko učinkovitost smo preverili. Rezultati ukrepov so pokazali, da s pomočjo le teh zmanjšamo rabo toplote in hladu. Izračunali smo rentabilnost predlaganih ukrepov in vračilno dobo investicije. Ugotovili smo, da se investicija v ukrepe ne bo hitro povrnila, vendar bo stavba energijsko učinkovitejša, kar bo zmanjšalo vpliv na okolje. Due to the growing problem with pollution has European Union committed to reduce the amount of emissions of greenhouse gasses. Big amount of them is being produced as a result of inefficient use of energy. As a member of EU, Slovenia is pursuing reduction of total energy consumption as well. For this reason, we have as a project of our thesis chosen the business building TR3, which is located on the Republic Square in Ljubljana. Using the programs DesignBuilder and EnergyPlus, we have calculated the required power of the chiller, the benefit of its potential substitution with the new one and the measures for reduction of total energy consumption. In the second section we have implemented three measures and have hereinafter reviewed their efficiency. Results have shown that with the use of these regulations we can more or less reduce the use of heating and cooling energy. At the end of thesis, we have calculated profitability of the regulations and payback period of the investment. We have concluded that the investment into regulations would not be fast repaid, nevertheless would the building be more energetically efficient and its environmental impact would be lower. raba energije modeliranje ukrepi za zmanjšanje rabe energije rentabilnost ukrepov vračilna doba investicij efficient energy use modelling measures of reduction of the use of energy viability of the measures return on investment true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-11 13:34:09 2017-09-11 13:34:10 2023-10-24 08:57:41 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 200049 979.pdf 979.pdf 1 76985A5653413ABCBC83A9F8B4E374F1 31be99ca8a5641658aaac5774ff3c1c9361d223e4d17f1b67e90609a2c7ad329 a3d1fc1b-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/7b551a90-1c90-4228-888a-419c4e4df3b8 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=103425 Fakulteta za strojništvo 0 0 0
