Economic Effects in Energy Renovation of Residential Buildings

U građevinskim sektorom otpada oko 40% ukupne potrošnje energije u Europskoj uniji. Energetska učinkovitost u zgradama i dalje je važno pitanje. Veliki napredak je napravljen u smanjenju potrošnje energije kod obnovljenih zgrada, ali veliki količina postojećih zgrada s lošom energetskom snagom vjerojatno su još važnije područje na koje treba postaviti fokus. Ovaj diplomski rad obuhvaća strategije, programe i inicijative EU u okviru energetske učinkovitosti uz pomoću koji se može efikasnije realizirati obnova stambenih zgrada te ostvariti ekonomski učinci istih. U Hrvatskoj postoje strategije i nacionalni programi za povećanje energetske učinkovitosti. S ciljem analiziranja i kalkuliranja privilegija i koristi koriste se računalni programi za kalkulaciju cjelokupnih energetskih potreba kao i ekonomskih učinaka odnosno uštede energije. Ušteda energije kroz smanjenu potrošnju energije je izravna korist koja proizlazi iz povećane energetske učinkovitosti. Kreatori politike trebali bi biti sposobni razlikovati željene i neželjene rezultate energetske učinkovitosti, te razumjeti uzajamstvo različitih socio-ekonomskih uzročnika koji ih prouzrokuju.The building sector accounts for about 40% of total energy consumption in the European Union. Energy efficiency in buildings is still an important issue. Great progress has been made in reducing energy consumption in refurbished buildings, but a large number of existing low energy buildings are probably the most important area to focus on. This graduate thesis includes EU energy efficiency strategies, programs and initiatives, with the aim of efficiently realizing the renovation of residential buildings and achieving their economic effects. There are strategies and national programs for increasing energy efficiency in Croatia. In order to analyze and calculate privileges and benefits, computer programs are used to calculate total energy needs as well as economic effects or energy savings. Energy savings through reduced energy consumption are a direct benefit of increased energy efficiency. Political creators should be able to differentiate the desired and undesirable results of energy efficiency and understand the mutuality of the various socio-economic agents that cause them
