The aim of this article is to contribute to the summer thermal performance of external timber frame wall by the simultaneous use of experimental measurements and numerical simulations. The measurements were taken on an experimental timber frame passive house. The numerical modeling of the external wall using a dynamic simulation program ANSYS. The results of research are presented and discussed. It is shown that the numerical simulation methods are suitable tools for the prediction of thermal behaviour of light-weight timber-based construction.

For the best possible thermal-technical properties of building structures it is necessary to use materials with very low thermal conductivity. Due to the increasing thermal-technical requirements for building structures, the insulating materials are developed. One of the modern thermal insulating materials is so-called aerogel. Unfortunately, this material is not used in the field of external thermal insulation composite systems because of its price and its properties. The aim of this paper is to present possibilities of using this insulating material in the civil engineering - specifically a usage of aerogel in the production of windows.

In accordance with the requirements for the optimal control settings of the operating and technical functions in Smart Home (SH) in order to reduce SH operating costs, it is also necessary to provide healthy microclimate and the required quality parameters of the SH internal environment in the individual SH rooms. The article describes the basic principles and methods of evaluation of thermal comfort of the internal environment using objective and subjective factors. The experimental measurements of objective parameters of the internal environment and thermal comfort evaluation were conducted in a selected SH room in a wooden building of the passive standard located in the Faculty of Civil Engineering, VSB - TU Ostrava.

The paper analyses results of the experimental measurements and numerical simulations of the winter and summer temperature response in the light timber structure. In the article there is evaluated the suitability of using of the theoretical numerical methods for a thermal field prediction in a building structure exposed to non-stationary boundary conditions.
