This article describes a part of experimental measurement with assistance of independent weather station. Later on, after the data processing from chosen period of time (1 week in March 2014) measurements are described, graphic processed, interpreted and compared to the results of real meteorological station from SHMÚ. Convenient climatic units are elaborated. The influence of differences in measured data on results of calculations for thermal technical parameters of covering constructions is analysed.

The article will present the partial knowledge of the area of thermal properties of the wooden lightweight external walls. The temperatures on the monitored samples of walls built in the air-conditioned room in the Laboratory of pavilion type for one week in cool, intermediate and warm periods will be shown. It will be described as the wall develops under the stationary conditions of the internal environment and the real conditions outside changed during the selected time period. Further differences in surface temperatures affected tone color design plaster used on the exterior facades will be followed. The thermal parameters of variant wall constructions, obtained under the steady state and non-steady thermal state and simulations will be compared.

The paper evaluated thermo-technical characteristics of the experimental walls, consisting of five different tracks in three different color surfaces at different base material. The hygrothermal behavior of the structures and layers is monitored year-round. The computational model of the laboratory room and tested samples is compiled and debugged on the basis of experimental measurements. The dynamic simulations of temperature and humidity parameters were realized.
