Energy renovation of earthquake-damaged buildings to nearly zero energy levels

Cilj ovog rada izrada je projekta energetske obnove postojeće zgrade oštećene u potresu do razine gotovo nulte energije poštujući razinu spomeničke zaštite zgrade. Izrađen je 3D model postojećeg stanja zgrade u računalnom programu ArchiCad. Proračun potrebne energije za grijanje i hlađenje zgrade proveden je u skladu s Algoritmom za proračun potrebne energije za grijanje i hlađenje zgrade prema HRN EN ISO 13790. Uspoređeni su rezultati proračuna postojećeg stanja i stanja nakon seizmičke i energetske obnove. Dodatno je provedena analiza toplinskih mostova pri čemu su dobivene vrijednosti linijskih koeficijenata prolaska topline. Također je provedena analiza difuzije vodene pare korištenjem računalnog programa. Rezultat rada je definirano rješenje i sustav energetske obnove zgrade oštećene u potresu do razine gotovo nulte energije.The aim of this paper is to develop a project for the energy renovation of earthquake-damaged building to nearly zero energy level, respecting the level of monumental protection of the building. 3D model of the current state of the building in the ArchiCad software was created. The calculation of the required energy for heating and cooling of the building was done in accordance with the Algorithm for calculating the required energy for heating and cooling of buildings according to HRN EN ISO 13790. The results of the calculation of pre-renovation and post-renovation were compared. In addition, the analysis of thermal bridges were calculated. An analysis of water vapour diffusion was also calculated in computer software. The result of the paper is defined solution and system of energy renovation of the earthquake- damaged building to nearly zero energy level
