    Thermal technical analysis of lightweight timber-based external wall structures with ventilated air gap
    (MDPI, 2021) Valachová, Denisa; Baďurová, Andrea; Skotnicová, Iveta
    Lightweight timber-based structures are an increasingly common part of envelopes of new buildings due to increasing requirements for their energy performance. In addition, due to the fact that wood is a sustainable material, it can be assumed that the share of these structures in civil engineering will continue to increase. The subject of this article is the thermal analysis of timber-based lightweight structures under winter conditions to expand information about thermal processes in these structures. This article deals with the lightweight timber-based external wall structures with a ventilated facade and a double-skin roof structure. Experimental temperature measurements inside the structures and ventilated air gaps are used to perform the thermal analysis. By comparing experimental and theoretical data obtained by performing numerical simulation, it was shown that for achieving an ideal match of numerical simulations and measured physical properties it is necessary to take into account not only external temperatures affecting these structures, but also other factors such as solar radiation and heat emission into the cold night sky. In the case of the external walls with ventilated facade, the benefit of a ventilated air gap has been demonstrated in relation to smaller temperature fluctuations that affect the structures.

    Using the finite element method to predict heat dissipation in a timber frame building construction
    (Výskumný ústav papiera a celulózy, 2019) Valachová, Denisa; Skotnicová, Iveta
    This article focuses on thermal engineering assessment of light building envelope structures using Finite Element Method (FEM). The research was carried out for a particular composition of a lightweight perimeter wall in winter, for which continuous experimental measurements are also carried out. In the preparation of calculation models for numerical simulation, the marginal conditions, which were obtained by experimental measurement, were used. Thus, for simulation purposes, the construction was loaded under the same boundary conditions as the actual structure being monitored within which experimental measurements were performed. The results of the experimental measurement made it possible to compare the actual measured data with the results of the numerical simulation. The difference between calculated and experimentally determined temperatures was in the range from 0.1 degrees C to 1.3 degrees C. This study demonstrated, that with the help of suitable simulation programs, it is possible to predict the thermal-technical behavior of lightweight perimeter constructions.

    Using of aerogel to improve thermal insulating properties of windows
    (De Gruyter, 2018) Valachová, Denisa; Zdražilová, Naďa; Panovec, Vladan; Skotnicová, Iveta
    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.
