Therefore, the environmental impact of composite wood-based materials is crucial for sustainable construction. The aim of this paper is to present the results of research on the environmental impact assessment of the external wall assembly of wood-based structures used in wood constructions. Eight wall assemblies usable in ultra-low energy structures and nearly-zero energy buildings (passive buildings) with U-values in the range from 0.099-0.211 W/(m2K) were includedin the analysed and evaluated group. The environmental analysis Life Cycle Impact Assessment (LCIA) was performed by SimaPro software,using the IMPACT2002+ method in terms of an impact on selected components (human health, ecosystem quality, climate change, resources). An assembly based on a cross-laminated timber (CLT) panel with insulation on the blown cellulose base was evaluated as a structure with the greatest environmental impact, closely followed by the assembly based on a box beam with glass-based mineral insulation. The impact assessments of both of these assemblies were more than 16 mPt. On the other hand, structures using wood fibre, straw and especially sheep wool as insulation were assemblies with the least negative impact on the environment. Their impact assessment was from 6.6-8.2 mPt. The research results also showed that the material assembly of the externalwall significantly influences the LCIA analysis result, and the choice of insulating material is the most important, as the insulation is more than 80% of the volume of the wood-based structures on average. The results of the life cycle analysis show that the selection of structural and especially insulating materials plays an important role in the case of wood constructions.
