Abstract
Denne kandidatafhandling vurderer energirenoveringstiltag og mulige løsninger på problemer med måling og afregning af varmeforbrug i en boligbygning i Zagreb. Arbejdet kombinerer en omfattende litteraturgennemgang, målrettet dataindsamling og en numerisk model (en computersimulation af bygningens varme- og energiforbrug), der er opbygget, så den afspejler forholdene i den konkrete bygning. Modellen er valideret mod faktiske data, og afhandlingen skitserer desuden den aktuelle situation i boligsektoren i både EU og Kroatien for at sætte casen i perspektiv. På baggrund af den validerede model udvikles flere renoveringsscenarier, som sammenlignes for at finde de mest omkostningseffektive løsninger. Resultaterne omfatter forventede varmesparelser, investeringsomkostninger og tilbagebetalingstid (den tid det tager, før besparelserne dækker investeringen). Derudover vurderes udvalgte muligheder for at forbedre metoden til måling og afregning af varme ved at sammenligne investeringsomkostninger og deres potentiale for at skabe incitamenter til varmesparelser gennem ændret adfærd og vaner hos beboerne. Afhandlingen afsluttes med en kritisk diskussion af antagelser, begrænsninger og valg samt en konklusion, der opsummerer resultaterne af energirenoveringen og justeringer af målings- og afregningsmetoden.
This master’s thesis evaluates energy renovation measures and practical solutions to address problems with metering and billing of heat use in a residential building in Zagreb. The study combines an extensive literature review, targeted data collection, and a numerical model (a computer simulation of the building’s heat and energy use) built to reflect the conditions in the real building. The model was validated against observed data, and the thesis also outlines the current situation in the residential sector in both the EU and Croatia to put the case in context. Based on the validated model, several renovation scenarios were developed and compared to identify the most cost-effective options. Results report expected heat savings, investment costs, and payback time (the time needed for savings to cover the investment). In addition, selected options to improve the metering and billing methodology were examined by comparing investment costs and their ability to encourage heat savings through changes in residents’ habits and behavior. The thesis concludes with a critical discussion of assumptions, limitations, and key decisions, and a conclusion that summarizes the outcomes of energy renovation and adjustments to the existing metering and billing approach.
