The thesis deals with accumulation abilities in wooden building structures of perimeter walls. Defined are thermotechnical parameters, which have an influence on the accumulation properties of the structure. In the next eight pieces of exterior walls are designed, which represent the current modern construction and material creation of wooden buildings. Basic thermotechnical properties, accumulation properties and parameters characterizing behavior in non-stationary temperature field are analyzed on selected wall compositions. Described wall parameters were simulated in a one-dimensional and two-dimensional temperature field in the dedicated software. The achieved results from the wall analysis are evaluated and on their basis are suggested recommendations how to improve the accumulation properties of the selected exterior wall composition with the worst accumulation ability.
