Abstract

Ovaj diplomski rad bavi se optimizacijom i određivanjem energetskog svojstva zgrade gotovo nulte energije obiteljske kuće u Zagrebačkoj županiji. U prvom dijelu obrađuje se teorijski dio vezan za energetsku učinkovitost u zgradarstvu i kriterije za zgrade gotovo nulte energije te je prikazan projekt obiteljske kuće u Zagrebu za kojeg se vrši analiza s obzirom na dvije različite vrste nosive konstrukcije – opeke i betona. U drugom dijelu provodi se proračun potrebne energije za grijanje i hlađenje koristeći satnu metodu 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. Također, provela se analiza utjecaja rješenja toplinskih mostova na ukupnu projektnu potrošnju energije u zgradama koristeći numerički model Croral za sedam izabranih kritičnih mjesta u oba slučaja nosive konstrukcije. Isto tako, na temelju postojećeg arhitektonskog projekta zgrade izrađen je model obiteljske kuće računalnim programom Allplane 2020. Koristeći količine pojedinih materijala koje su dobivene pomoću navedenog računalnog programa izrađen je troškovnik kako bi se analizirali troškovi potrebni za gradnju. Na kraju rada uspoređuju se rezultati navedenih proračuna te je definirano rješenje i sustav za zgradu gotovo nulte energije.

Abstract (english)

Theme of this master thesis is optimization and determination of energy propertis buildings with nearly zero energy emision on family house in Zagreb. The first part deals with the theoretical part related to energy efficiency in buildings and criteria for nearly zero energy buildings, and presents the project of a family house in Zagreb, which is analyzed with regard to two different types of load-bearing structures - brick and concrete. In the second part, the calculation of the required energy for heating and cooling is performed using the hourly method as defined in the Algorithm for calculating the required energy for heating and cooling the building according to HRN EN ISO 13790. Also, an analysis of the impact of thermal bridge solutions on the total design energy consumption in buildings was performed using the numerical Croral model for seven selected critical points in both load-bearing structures. Based on the existing architectural design of the building, a model of a family house was made with the computer program Allplane 2020. Quantities of individual materials were obtained using said computer program to analyze the costs required for construction. At the end the results of the mentioned calculations are compared for defining the solution and system for the nearly zero energy building.
