Calculation of heating and cooling energy demand of an apartment in a building

Završni rad sadrži pregled literature vezane uz energetsku učinkovitost u zgradama te kratki opis regulative u Hrvatskoj vezane uz energetske preglede zgrada i zgrada gotovo nulte energije. Opisana je i energetska bilanca na teoretskoj razini. U radu je napravljen brzi pregled stana u višestambenoj zgradi u Puli te su izrađene grafičke podloge predmetnog stana i crteži te opis građevnih dijelova vanjske ovojnice zgrade. U završnom radu proveden je proračun potrebne energije za grijanje i hlađenje za jednu stambenu jedinicu u postojećoj zgradi. Izrađen je model zgrade korištenjem odgovarajućih računalnih paketa, a pri proračunu je korištena satna metoda proračuna potrebne energije za grijanje i hlađenje zgrade kako je definirano u Algoritmu za proračun potrebne energije za grijanje i hlađenje prostora zgrade prema HRN EN ISO 13790.This work contains a literature review related to energy efficiency in buldings and a brief description of the regulations in Croatia related to energy audits of buildings and almost zero energy buildings. The energy balance of the building is described on a theoretical level. In the paper, a quick inspection o fan apartment in a multi-apartment building in Pula was made, and graphic bases of the apartment in question and drawings and a description of the construction parts of the outer envelope of the buildings were created. In the final work, the calculation of the required energy for heating and cooling for one residental unit in the existing building was carried out. A model of the building was created using appropriate computer packages, and the hourly method of calculating the required for heating and cooling the building was used for the calculation, as defined in the Algorithm for calculating the required energy for heating and cooling the building according to HRN EN ISO 13790
