“…They also found that the TPS technique is more universal than the transient hot wire (THW) or the transient hot strip (THS) methods, where the temperature measurement is localized to the thermocouple hot junction. Comparisons with proven older techniques, such as the steadystate and laser flash method, have demonstrated similar results, establishing that the TPS technique offers new opportunities for characterizing the thermal properties of wood, especially in the green state (Dupleix et al 2012;Gaff et al 2016;Kvasnová et al 2016;Mitterpach and Štefko 2016). Li et al (2013) proposed a modified step-wise transient method with special considerations of heat-loss effect occurring at the edge of measured samples, finite geometry of the sample, and orthotropic thermal conductivity.…”

The basic thermophysical properties of oriented strand boards were determined experimentally for use in humid conditions (OSB3) depending on the moisture content. The dependency between the thermal conductivity, thermal diffusivity, specific heat capacity, and the moisture content in the range of 0% to 10%, was examined. The non-stationary extended dynamic plane source (EDPS) experimental method was used. EDPS method was modified for anisotropic materials, i.e. with special considerations of heat-loss effect occurring at the edge of measuring samples, finite geometry of the sample and orthotropic thermal conductivity, for use with anisotropic materials. The validity of the experimental method was verified on polymethylmethacrylate (PMMA) samples. The error rate of measurements conducted on PMMA samples was less than 3%, and for OSB3 boards it was less than 5.5%. Based on the experimental results, regression equations of the dependency between the monitored properties and the moisture content were determined. In the case of thermal conductivity and thermal capacity, the determined dependencies showed a high correlation rate.

“…In our study, taking into account only external walls, this difference is 22% for the building with standard insulation. Mitterpach and Štefko [46] found that the materials for the construction of a brick house leave twice the carbon footprint in the environment than materials for a wooden house, but in this case it was a wooden log building.…”

Buildings consume energy, which is a major contributor to greenhouse gas emissions. In order to reduce their environmental impact, it is important to choose suitable building materials and energy source. The paper presents the results of a multi-variant analysis of five environmental impact categories (global warming potential, acidification, eutrophication, ozone layer depletion, and total use of primary energy) for a single-family house located in Poland in a 25-year life cycle. The tests were carried out for two different types of building structures (brick and wooden), two variants of external partition insulation, and four heat sources. The following computer programs were used for the calculations: OpenStudio and EnergyPlus, and One Click LCA. The analysis took into account the erection of the building in its shell and the energy consumption for heating in a 25-year life cycle. Studies have shown that when an electric heat source is used, the use stage has the greatest environmental impact, accounting for up to 80% of the total emissions over the life cycle. This ratio can be reduced by half in the case of a house with thicker external wall insulation and an eco-biomass boiler.

“…Much research focuses on the LCA of building materials (e.g. Christoforou et al, 2016;Jonsson et al, 1998;Mitterpach and Štefko, 2016;Zimele et al, 2019). Additionally, innovative ideas and the use of secondary material in building materials' production are assessed in many studies using LCA (e.g.…”
