Evropska energetska politika med drugim spodbuja energetsko učinkovitost in varčevanje z energijo ter razvijanje novih in obnovljivih virov energije. Energetska obnova OŠ Fara je bila izvedena v skladu s cilji in s pomočjo finančnih instrumentov te energetske politike. V diplomski nalogi sem obravnaval objekt OŠ Fara, na keterem se je leta 2013 izvedla obnova fasade s povečanjem debeline toplotne izolacije, zamenjava oken ter rekonstrukcija kotlovnice z namestitvijo kotla na lesne sekance. Analiza je zajela primerjavo izračunanih rezultatov toplotne bilance z računalniškimi programi TEDI, TOST in Gradbena fizika URSA4 pred in po obnovi objekta. Izvedel se tudi primerjavo računskih rezultatov z dejanskimi podatki o porabi energije v letu 2014. Na koncu pa sem analiziral investicijo tudi iz stroškovnega vidika ter podal predloge stroškovno učinkovitih ukrepov s področja učinkovite rabe energije na obravnavanem objektu v bodočnosti. Rezultati analiz so pokazali, da se računski rezultati dobljeni z različnimi računalniškimi programi medsebojno razlikujejo zelo malo. Izračunani rezultati toplotne bilance in podatki o dejanski porabi toplotne energije v edinem razpoložljivem letu 2014, pa se med seboj razlikujejo znatneje. Zaključki diplomske naloge kažejo, da so učinki energetske obnove objekta upravičili pričakovanja, saj bodo prihranki pri porabi toplotne energije potrebne za delovanje stavbe znatni, finančni učinki pa zaradi manjše porabe energije in tudi zaradi cenejšega energenta zelo veliki.

• Title: Analysis of energy balance befor and after energy renovation Elementary School Fara

Abstract

Promoting energy efficiency and saving as well as development of new and renewable energy sources are among the main goals of the EU energy policy. The energy renovation of Elementary School Fara in 2013 was done according to the principles and with the financial aid of this policy. The renovation comprised thickening of the heat insulation, replacing windows and a reconstruction of the boiler room including installation of a biomass boiler running on wood chips and pellets. The analysis includes a comparison of energy efficiency calculations done with computer software programmes TEDI, TOST and Gradbena Fizika URSA 4 before and after the renovation as well as a comparison of the computer calculations with the actual data on the use of energy in 2014. The thesis also includes cost analysis of the investment and recommendations on cost-efficient actions that should be taken to further improve energy efficiency of the building in the future. The results have shown that the computer data calculated with the use of different software programmes vary very little while the difference between the computer data and the actual data is more substantial. The analysis shows that the financial effects of the higher energy efficiency as well as the cheaper energy source will be quite large, which means that the energy renovation of the building has been successful.
