Abstract

Ovaj rad analizira sektor zgradarstva u Republici Hrvatskoj kroz energetsku učinkovitost i tranziciju prema održivim izvorima energije. Korištenjem LEAP (Low Emissions Analysis Platform) modela izrađena su tri različita scenarija do 2050. godine, koji prikazuju potencijalne ishode energetske obnove zgrada i njihov utjecaj na potrošnju energije.
Razmatrani su:
• Scenarij 1 – Zaustavljanje energetske obnove zgrada
• Scenarij 2 – Umjerena stopa obnove zgrada
• Scenarij 3 – Potpuna obnova zgrada
Analizom rezultata pokazano je da ambicioznija energetska obnova dovodi do značajnog smanjenja potrošnje energije što u konačnici dovodi do smanjenja emisija CO₂, dok scenarij bez obnove rezultira povećanjem potrošnje. Poseban naglasak stavljen je na prijelaz sa fosilnih goriva na električnu energiju, dizalice topline i solarnu energiju, pri čemu sektor usluga prednjači u implementaciji novih tehnologija.
Rezultati analize potvrđuju značaj energetske obnove u sektoru zgradarstva, pokazujući kako različite strategije mogu utjecati na potrošnju energije, strukturu energenata i emisije stakleničkih plinova do 2050. godine.

Abstract (english)

This paper analyzes the building sector in the Republic of Croatia through the lens of energy
efficiency and the transition to sustainable energy sources. Using the LEAP (Low Emissions
Analysis Platform) model, three different scenarios have been developed up to the year 2050,
illustrating potential outcomes of building energy renovation and its impact on energy
consumption.
The considered scenarios are:
 Scenario 1 – Halting building energy renovation
 Scenario 2 – Moderate rate of building renovation
 Scenario 3 – Complete building renovation
The analysis of results shows that a more ambitious energy renovation leads to a significant
reduction in energy consumption, ultimately resulting in lower CO₂ emissions, whereas the
scenario without renovation results in increased energy consumption. Special emphasis is
placed on the transition from fossil fuels to electricity, heat pumps, and solar energy, with the
service sector leading the way in the adoption of new technologies.
The results of the analysis confirm the importance of energy renovation in the building sector,
demonstrating how different strategies can influence energy consumption, the energy mix, and
greenhouse gas emissions by 2050.
