Comparative analysis of energy efficiency indicatorsof Nearly Zero Energy Buildings

V diplomski nalogi smo izvedli primerjalno analizo energijske učinkovitosti stavbe na osnovi kazalnikov opredeljenih v Pravilniku o energijski učinkovitosti stavb iz leta 2010 in 2022. Posodobljen pravilnik uvaja zahteve za skoraj nič energijske stavbe, ki jih morajo izpolnjevati vse nove in rekonstruirane stavbe. Glede na zahteve posodobljenega pravilnika smo analizo izdelali za vse predvidene energetske zahtevnosti stavb. Kazalnike energijske učinkovitosti izbrane stavbe smo določili za nivo potrebne energije za zagotavljanje bivalnega ugodja, nivo dovedene energije in nivo potrebne primarne energije, ki je osnova za določitev kazalnikov skoraj nič energijskih stavb. Izdelali smo primerjavo različnih ukrepov učinkovite rabe energije, sistemov za ogrevanje in pripravo tople sanitarne vode ter tehnologij za proizvodnjo toplote in električne energije na stavbi. Ugotovili smo, da posodobljen pravilnik bistveno zaostruje zahteve glede energijske učinkovitosti, vendar je te mogoče izpolniti s premišljenim načrtovanjem tehničnih stavbnih sistemov.In this thesis, we performed a comparative analysis of the building\u27s energy efficiency, based on the indicators defined in the Regulations on the Energy Efficiency of Buildings from 2010 and 2022. The updated regulations introduce requirements for almost zero energy buildings, which must be met by all new and reconstructed buildings. By basing ourselves on the updated rule book’s requirements, we made an analysis for all the anticipated energy requirements that buildings will have to meet. We determined the energy efficiency indicators of the selected building for the level of energy required to ensure living comfort, the level of supplied energy and the level of required primary energy, which is the basis for determining the indicators of almost zero energy buildings. We made a comparison of various measures of efficient energy use, systems for heating and preparation of hot sanitary water, and lastly, technologies for the production of heat and electricity in the building. By doing so, we found that the updated regulation significantly tightens the energy efficiency requirements, but these can be met by thoughtful technical planning of the building’s systems
