As far as modern building technological and material solutions, wood-based constructions are more often applied. New technologies in wood constructions allow to design and construct buildings in low-energy and passive building standards. Producers of system solutions provide the catalogues of different system construction details. The aim of this article is the analysis of thermal bridges of different solution details of both, framework and massive board wood construction. The analysis were conducted in THERM 6.3 program, prepared by Lawrence Berkley National Laboratory. THERM enables to model the effects of two- dimensional heat flow effect and is based on finite elements method, which allows modeling of both simple and geometrically complicated building components. All the results of software calculation facilitates the analysis of the heat exchange and finally allows for the estimation of energy effctiveness. Analyzis of local temperature values allows for assessment of condensation and mould growth problems.
