Abstract

V zadnjem času se veliko govori o negativnih vplivih poseganja človeka v okolje. Podnebne spremembe, ozonska luknja, segrevanje ozračja, onesnaženost zraka so le nekatere izmed negativnih posledic. Poleg teh pa se zaloge neobnovljivih virov energije zmanjšujejo, zato postaja energija vse bolj dragocena dobrina. Ena izmed metod za ugotavljanje negativnih vplivov na okolje je metoda analize življenjskega cikla ali LCA. V magistrski nalogi je najprej predstavljena metoda LCA, z njo povezana standardizacija, njene značilnosti, proces in njena uporaba v gradbeništvu. V nadaljevanju je predstavljen fasadni sistem in njegove komponente. Za lepilno malto, zaključni omet ter za fasadni sistem je izveden izračun LCA (»od zibelke do vrat«) z realnimi podatki ter predstavitev rezultatov v obliki okoljske deklaracije proizvoda EPD. V zadnjem delu je primerjava okoljskih vplivov za fasadne plošče, zaključne omete ter za fasadne sisteme. Fasadne plošče smo primerjali glede na LCA rezultate izračunane iz podatkovnih baz. Za primerjavo zaključnih ometov smo uporabili javno dostopne EPD-je in predhodno izračunani LCA za zaključni omet. Nazadnje smo kombinirali različne fasadne plošče in zaključne omete v fasadne sisteme, izračunali LCA, in izvedli primerjavo fasadnih sistemov. Ugotovili smo, da je edina pravilna primerjava z upoštevanjem deklarirane enote glede na funkcijo, ki jo material opravlja, in ne na masno enoto. Rezultati se med posameznimi kazalci okoljskih vplivov razlikujejo, zato je potrebno primerjati več različnih kazalcev. Iz LCA ugotavljamo, da ima na fasadne sisteme pri večini kazalcev okoljskih vplivov največji vpliv fasadna plošča, medtem ko izbira zaključnega ometa na kazalec okoljskega vpliva nima odločilne vloge.

Secondary title:	Environmental valuation of external thermal insulation composite systems
Secondary abstract:	Lately, there has been a lot of discussion about negative impacts on the environment that are caused by human actions. Climate change, ozone hole, global warming, air pollution are only some of the many negative impacts. In addition, non-renewable energy resources (such as oil, natural gas, coal) are being depleted, causing energy to increasingly become more and more valuable. One of the methods for detection of such negative environmental impacts is the socalled life cycle assessment method or LCA. First part of the master thesis presents the LCA method and with it connected standardization, its characteristics, process and its use in construction industry. It continues with the presentation of the ETICS and its components. The LCA calculation (“from cradle to gate”) using real data and the presentation of the results in form of the environmental product declaration EPD, is carried out for adhesive mortar, finishing coat and ETICS. Last part of this thesis presents the comparison of the environmental impacts on thermal insulation materials, finishing coats and ETICS. We compared the thermal insulation materials according to the LCA results that were calculated from the databases. For comparison of the finishing coats we used publicly available EPD and the finishing coat we calculated ourselves. Lastly we combined different thermal insulation materials and finishing coats into ETICS, calculated LCA and compared the ETICS. We have found that the only right comparison including declared unit is the one that is based on the function of the material and not on the mass unit of the material. The results vary according to different environmental impact indicators, therefore it is necessary to compare different indicators among themselves. Using LCA we came to a conclusion that the thermal insulation material has the biggest impact on the ETICS in majority of the environmental impact indicators, while the choice of finishing coat does not play a key role for environmental impact indicators.
