dc.description.abstractApproximately 40% of final energy is consumed in buildings both in Lithuania and the European Union. In cold climate countries major part of the consumed energy is heat. Therefore, in order to build energy efficient buildings it is very important at the design stage to make a right decision regarding the choice of the heating system. The aim of the study is to compare three different heating systems from the point of view of a sustainable development concept. This paper summarizes results of the life cycle analysis, which has been made on the heating systems of an existing residential building. The purpose of this study is to define the primary energy consumption, CO2 emissions and investments necessary for the three different heating systems during their life span and to evaluate them applying a multicriteria approach. The systems under consideration are the heating systems comprising a standard cast-iron gas boiler and steel radiators or a condensing gas boiler combined with floor heating or a condensing gas boiler combined with steel radiators. A life cycle assessment has been made for the life span of 80 years. As a final decision making criteria the 3E criteria is proposed.eng
dc.description.abstractTiek Lietuvoje, tiek Europos Sąjungoje pastatuose suvartojama apie 40 % galutinės energijos. Šalto klimato šalyse pagrindinis energijos kiekis suvartojamas pastatams šildyti. Todėl statant energetiškai efektyvius pastatus labai svarbu dar projektuojant priimti teisingus sprendimus dėl jų šildymo sistemų. Atliktos analizės tikslas buvo palyginti tris skirtingas šildymo sistemas darnaus vystymosi požiūriu. Straipsnyje pateikiami apibendrinti atliktos esamo gyvenamojo namo šildymo sistemų variantų gyvavimo ciklo analizės rezultatai: pirminės energijos sąnaudos, CO2 emisija ir investicijos per jų gyvavimo laiką. Sistemos įvertintos taikant daugiakriterinį vertinimą. Atliekant tyrimą buvo palyginti trys šildymo sistemų variantai: standartinis ketaus katilas su plieniniais radiatoriais, kondensacinis katilas su grindų šildymu ir kondensacinis katilas su plieniniais radiatoriais. Gyvavimo ciklo analizė atlikta imant, kad šildymo sistemos gyvavimo laikas yra 80 metų. Kaip galutinis vertinimo kriterijus pasiūlytas 3E kriterijus.lit
