Abstract

Trajnostna in energetsko učinkovita gradnja je danes ena od aktualnih tem, zato smo v diplomski nalogi izračunali energetsko bilanco za manjšo enodružinsko hišo ter preverili ustreznost konstrukcijskih sklopov zunanjih sten glede na izbrane kriterije trajnosti. V diplomski nalogi so izbrani leseni konstrukcijski sklopi zunanje stene, ki jih najdemo na slovenskem tržišču. Določena sta tudi dva konvencionalna konstrukcijska sklopa iz opeke in armiranega betona. V teoretičnem ozadju so opredeljeni lesni kompoziti, ki jih najdemo v izbranih konstrukcijskih sklopih ter pojmi, ki se nanašajo na trajnost oziroma trajnostnost, trajnostni razvoj, trajnostno arhitekturo, trajnostno stavbo in trajnostno gradnjo. Preverjena je energetska učinkovitost posameznih izbranih konstrukcijskih sklopov na primeru enodružinske nizkoenergijske hiše tipa Prima, ki je produkt podjetja Marles. Poleg tega smo po metodi Dovjak in Krainer [12] določili vidike trajnosti ter posamezne kriterije, ki smo jih analizirali na podlagi sestave izbranih lesenih konstrukcijskih sklopov. Obravnavali smo okoljski, socialni, ekonomski in zdravstveni kriteriji. Ugotovili smo, da energetsko učinkovitost stavbe narekuje toplotna prehodnost konstrukcijskega sklopa, zato ni nujno, da je lesen konstrukcijski sklop bolj energetsko učinkovit od konvencionalnega. Pri analizi trajnostne gradnje se izkaže lesena gradnja za bolj trajnostno od konvencionalne, čeprav ne izpolnjuje vseh kriterijev trajnosti (okoljski, ekonomski, socialni, zdravstveni). Da bi v celoti izpolnili vse kriterije, se je potrebno izogniti uvozu lesa in lesnih kompozitov, ki škodujejo zdravju ljudi in okolju ter uporabiti les brez dodatkov.

Secondary title:	Energy And Sustainability Aspects of Wood Construction
Secondary abstract:	Nowadays sustainable and energy-efficient construction is one of the top issues, therefore in my graduation thesis we calculated the energy balance of a small family house and checked the suitability of wooden structural complexes of exterior walls according to selected criteria of sustainability. In this thesis we chose wooden structural complexes of exterior walls, which can be found in the Slovenian market. We also specified two conventional structural complexes of brick and reinforced concrete. The theoretical part defines wood composites, which are found in selected structural complexes and concepts of sustainability, sustainable development, sustainable architecture, sustainable building and sustainable engineering. Energy efficency of selected structural complexes is shown in the case of a single-family lowenergy house type called Prima, which is the product of company Marles. In addition, we used the Dovjak and Krainer method [12] to define sustainability aspects and specific criteria, which were analyzed on the basis of the composition of selected wooden structural complexes. We discussed environmental, social, economic and health criteria of sustainability. We found out that the energy efficency of a building is determined by thermal transmittance of frame construction. For this reason it is not necessary that the wood-frame construction is more energy efficient than the conventional one. In the analysis of the sustainability it is proven that wood-frame construction are more sustainable than conventional, though not to meet demands of sustainability (environmental, economic, social, health). In order to fully meet all the criteria should be avoided imports of wood and wood composites, and use wood without adhesives and resins, which are bad for health and the environment.
