“…It follows that construction and building technologies are also responding much faster to global challenges in the field of sustainability of energy, resources, environment, but also intelligent design solutions [11] or better customization of provided services in the field of construction supply [12]. Modern technologies and methods in the construction industry are currently marked by the trend of sustainability and increasing productivity by new modern technologies or by innovation of traditional modern methods [13][14][15]. The term Modern Methods of Construction (MMC) is a common term for building technologies and off-site and innovative on-site technologies.…”

We are on the threshold of a technological revolution that fundamentally changes the way we live, work and communicate with each other. To some extent, scale and complexity, this transformation will be as fundamental to humanity as no other technological change in the past. We do not know how it will evolve, but one thing is clear: the response to it must be integrated and comprehensive, involving all stakeholders on a global basis, from the public to the private sector, to the academic community and to civil society. In the context of sustainable and efficient construction, traditional material bases such as wood are becoming increasingly prevalent and implemented in modern design processes and design solutions. The great potential of this building material is achieved due to developments in production as well as the actual construction of timber buildings. Possible ways of production and construction of wooden buildings are diverse. Especially through prefabricated and solid wood products, which are also cross-glued laminated timber products, modern timber construction represents an interesting and sustainable construction technology. The aim of this paper is to define the basic aspects of industrial building industry in the context of new trends and to introduce the possibilities of implementation of elements of industry 4.0 in the field of wood-based construction.

“…However, when choosing materials for wooden buildings, it is necessary to take into account their thermal insulation properties in the context of the subsequent operation of buildings and their energy efficiency [17][18][19][20]. The choice of materials and technologies is not easy and, in addition to the technical parameters that determine the suitability of their use in a particular type of construction, the financial aspect and, to a large extent, the ecological thinking of the investor play a role [21][22][23][24]. Structural systems of wooden buildings are very diverse in today's houses, not only in terms of construction and insulation materials used, but also in terms of the technological equipment of the house, such as heat pumps, controlled ventilation or photovoltaics.…”

Analysis of the Characteristics of External Walls of Wooden Prefab Cross Laminated Timber

A balanced combination of heat flows creates suitable conditions for thermal comfort—a factor contributing to the quality of the internal environment of buildings. The presented analysis of selected thermal-technical parameters is up-to-date and suitable for verifying the parameters of building constructions. The research also applied a methodology for examining the acoustic parameters of structural parts of buildings in laboratory conditions. In this research, selected variant solutions of perimeter walls based on prefab cross laminated timber were investigated in terms of acoustic and thermal-technical properties. The variants structures were investigated in laboratory but also in model conditions. The results of the analyses show significant differences between the theoretical or declared parameters and the values measured in laboratory conditions. The deviations of experimental measurements from the calculated or declared parameters were not as significant for variant B as they were for variant A. These findings show that for these analyzed sandwich structures based on wood, it is not always possible to reliably declare calculated values of thermal-technical and acoustic parameters. It is necessary to thoroughly examine such design variants, which would contribute to the knowledge in this field of research of construction systems based on wood.

“…A reduction in energy demand in buildings is usually achieved by improving the thermal insulation properties of building structures [30], through a more efficient design, and by choosing materials that are efficient in terms of thermal insulation parameters. It is necessary for building designs to rely on theoretical knowledge that accommodates energy efficiency [31] and the environmental principles of creating the optimal state of the internal environment of buildings that allow achieving more sustainable buildings [32,33]. For a solution for a specific thermal state of the environment that meets the expectations [34] and requirements of the given user, it is necessary to analyse the relations between the parameters of the thermal state of the environment [35] and energy demand for heating [36].…”

Energy-efficient buildings, sustainable buildings, smart buildings, nearly zero-energy buildings, passive and active buildings are construction concepts widely recognised as setting the latest trends. The purpose of their design is to create an optimal thermal microclimate by means of heat flows that are either formed within it or enter into it. This research paper presents an analysis of the measurements of the density of heat flows, their spread in building constructions, all of which is examined in laboratory conditions and confronted with calculation models. The hypothesis of this research is to confirm or refute whether the computational models match the laboratory simulations in terms of thermal-technical parameters. The research uses a methodology designed for examining building constructions under virtually stable conditions. Two variants of external sandwich walls based on prefab cross laminated timber panels (variant A) and structural insulated panel (variant B) were proposed as the subject of the study. Both variants were subjected to research in laboratory conditions and computational simulations. For the sake of comparison, the calculation simulations that manufacturers of wood construction systems typically declare were also performed. The results of the analyses show significant differences between the theoretical or declared parameters and the values measured in laboratory conditions (7.5–32.6%). The deviations of the experimental measurements from the calculated or declared parameters were not as significant for variant A as they were for variant B. These findings show that for these analysed sandwich structures based on wood, it is not always possible to reliably declare calculated values of thermal-technical parameters. The publication is also a contribution to the current needs in the field of heating technology in terms of sustainability and the quality of internal environments.
