“Ecological buildings” and “energy-efficient buildings” are concepts which we encounter on a daily basis and which define modern trends. The purpose of their design is to create an optimal thermal microclimate by means of heat flows that form within it or enter it. A balanced combination of heat flows creates suitable conditions for thermal comfort—a factor contributing to the quality of the internal environment of buildings. This research addresses the problem of heat distribution in construction materials based on wood and their thermal–technical properties in relation to the sustainability requirements for the thermal–technical properties of constructions and buildings. The research examines the structural parts of the external walls of modern log constructions. The objective of this work is to analyse the thermal–technical properties of the structural parts of modern log wood constructions in laboratory conditions and verify them against calculated values and values declared by manufacturers. This publication is also a contribution to the current needs in terms of the sustainability and internal environment quality of constructions in general. 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.

Industry and industrial complexes are often located in the proximity of people’s homes. One of the negative effects of industry is noise emissions into the surrounding environment. With the increasing concentration of the human population and the increase in industrial production, more and more people are exposed to the negative effects of noise. This article discusses a comprehensive approach to reducing noise emissions from industrial operations, and the subsequent impacts on surrounding villages and human health. The first step of the whole process is to understand the current state of the acoustic situation in industrial operation and in the nearby villages, an important part of which is the identification and localization of dominant noise sources. For this purpose, a unique noise visualization tool was used, namely, an acoustic camera. The next important step is to propose a technical solution and measures to reduce the noise of the individual source. Consequently, it is necessary to create a mathematical model, i.e., noise maps, in order to verify whether the proposed measures will be sufficient. Once the proposed measures have been implemented, verification of the effectiveness of these measures needs to be carried out through repeated noise measurements in nearby villages and also on the site of the industrial installation. The above procedure was applied to the operation of a wastewater treatment plant that was causing noise exceeding the permissible levels in the surrounding villages. The application of this approach, the implementation of the proposed measures, and the subsequent verification confirmed a significant reduction in the noise levels in the affected villages, and the measures implemented were assessed as highly effective.

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.

The topic of energy efficiency is currently under discussion. One of the areas of energy efficiency is the energy efficiency of buildings. The thermo-technical requirements for building envelope structures are gaining increasing importance due to new legislation and technical regulations regarding the reduction of heating and energy demands of buildings over time and because of continuously increasing energy prices. Building construction and the operational costs of buildings are among the largest consumers of material and energy resources and environmental pollutants. Ecological constructions are a response to the current state of the environment. A suitable solution that represents ecological construction, operation and comfortable living is the construction of low-energy and passive houses based on wood. Wood-based buildings have many benefits that are particularly timely in the context of sustainability today. The aim of this paper is to introduce selected aspects of wood-based buildings in the context of energy efficiency and thus to reduce the adverse effects of construction on the surrounding environment.

In the construction industry, it is the material production phase and the use phase of buildings’ life cycles that represent the greatest environmental burden. The presented research focused on wood constructions during their use phase. The primary objective of the research was to determine the amount of CO2 produced during the operation of specific wood constructions in connection with the energy demand for their heating. A correlation analysis of selected parameters revealed a statistically significant correlation between heating medium type and energy demand for heating (p = −0.5773) and between heating medium type and amount of CO2 produced (p = 0.4796). A more detailed analysis showed that, in terms of the average energy demand for heating, the column constructions were the most efficient among the compared construction systems, regardless of the energy standard. Similar findings were obtained for annual CO2 production in connection with the average energy demand for heating. The only difference was that the panel and log constructions exhibited almost identical parameters, which came as a surprise to some extent. The column constructions turned out to be the most efficient again, regardless of their energy standard. The analysis that focused on the heating medium type revealed statistically significant differences among the heating medium types in energy demand for heating (p < 0.0001). The constructions that used electricity for heating were the most energy-efficient. When the individual characteristics of the different heating media in relation to CO2 production were taken into account, the constructions that were heated using biomass were the least polluting. The constructions heated using electricity and gas showed a significantly greater deviation.

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.

This research is focused on the much-debated issues regarding the low degree of efficiency and sustainability in the construction industry. The objective of this work is to present an evaluation of the efficiency and sustainability of buildings, and to determine, based on analyses of socio-economic research and theoretical assumptions, the degree of efficiency of modern methods of construction based on wood. The socio-economic research relies on the reports of users of completed constructions, which allowed a comparison of efficiency as perceived by users with efficiency as declared by manufacturers. The analysed constructions and the opinions of their users were identified in cooperation with various organizations operating in the wood-based construction sector and using databases of buildings already in use. A total of 160 constructions were analysed along with the opinions of their users. This comparison of the efficiency of construction systems in terms of selected sustainability parameters suggests that wood-based panel constructions constructed by a supplier company have the highest degree of efficiency. Constructions completed using a combined construction method are the least efficient (a combination of completion by a supplier firm with do it yourself completion). The work’s main contribution is an innovative approach to evaluating modern methods of construction based on wood by collecting information from users, as users can give the most valuable feedback that is based on their own experience after purchasing their houses. This approach to addressing the issues allowed identification of the advantages and disadvantages of wood-based constructions, which can have a positive impact on the practices and companies in the construction sector. The presented research delivers a number of results produced by the analyses and the socio-economic research, possibly boosting awareness of the advantages of wood-based constructions in terms of sustainability.

Over recent years farming has undergone fundamental changes and many aspects of the industry, including farm buildings, have been transformed thereby. Modern farm buildings are large and as cheap and maintenance free as possible reflecting the need for better performance and greater efficiency. These modern buildings however are much larger than traditional buildings and are constructed of materials which are not only artificial and 'foreign' to the area but are also very light coloured. As a result, modern economic buildings are characterized by specific features as traditional construction. Response to this trend are the modern methods of construction based on wood offering effective procedures (design and implementation of construction), resulting in a larger volume of products (production), with higher quality and with shorter time of their purchase. The aim of this paper is to present selected aspects of agricultural construction and their application at present.

This research paper focuses on agricultural constructions, a special type of constructions with an important role in industry and agriculture. Food production is an important social factor that is vital to human survival, so its qualitative aspect is a key determinant of living standards and is also important in terms of sustainability. The need to create a suitable environment (welfare) for animals, as a factor in terms of health and productivity, is drawing increasing attention. The environment continuously and directly affects animals, so it is quickly reflected in their productivity and medical condition. The objective of this research paper is to present an analysis of the interactions between agricultural constructions’ outdoor and indoor environment by monitoring an actual operational construction designed for animal rearing, from the point of view of animal welfare and sustainability, taking into account thermal protection and indoor climate.

Matters related to saving fuel, energy, and financial resources in particular, with respect to sustainability, are a much-debated topic. This means that one of the main considerations in the design and construction of new buildings, as well as in the case of existing buildings, is their energy consumption during use. Many newly-constructed buildings are already designed as low-energy or passive buildings. Construction systems based on wood are often assessed for these energy standards, as they have very positive thermal-technical properties. Construction time for wood constructions is very short, with a low – sometimes even negative – ecological footprint. The use of wood and structural elements based on wood save non-renewable resources, which is also highly desirable from the perspective of a sustainability philosophy. In terms of construction physics, we often encounter opinions in construction practice that the accumulation properties of wood constructions are not as positive as those of traditional materials such as brick, steel or concrete. With the above in mind, we formulated a hypothesis about the effect of accumulation elements on the energy consumption of wood constructions. The proposed hypothesis gave us an objective prompting us to analyse already completed constructions in actual use in terms of the presence of accumulation elements located in the constructions, and in terms of their effect on the energy consumption of the examined constructions. In our research of these actual wood constructions, we recorded a statistically significant effect of the presence of accumulation elements on the energy consumption of these examined constructions, both in terms of energy use and costs. This means that there is a clear benefit in using accumulation elements in wood constructions. These improvements in the structural properties of wood constructions can ultimately improve the properties of the resulting structure in many respects, whether in terms of cost saving, the level of comfort for users, or sustainability in general. Another contribution of our work is in raising awareness of constructions based on wood among all those who are involved in the construction process.

Blood analyses can be used to assess the health and physiological conditions of wild animals and may provide a precise picture of disease, habitat quality, and other environmental factors. The objective of this study was to analyze the relationship between the age and the selected biochemical parameters of the female mouflon (Ovis musimon L.). This study creates a possible reference range of biochemical parameter concentrations in mouflon and aims to extend the knowledge of this wild game species within our geographical region. There have not been many studies dealing with this issue in our geographical region. A total of 57 female mouflons aged between 1 and 6 years (1-3 years n = 32, 4-6 years n = 25) and in good physical condition, with an average live weight between 32 and 40 kg were included in the research experiment between the two years. A total of 15 selected biochemical parameters were analyzed. Using statistical analysis, we noticed significant effects of age on almost three-quarters of analyzed biochemical parameters. A statistically significant correlation was observed between age and the parameters of glucose, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, bilirubin, cholesterol, creatinine, high-density lipoprotein, calcium, triglycerides, and urea. An evaluation of the European mouflon's biochemical parameters during the whole year may be a reliable method for judging a herd's condition, diagnosing medical disorders, and preventing the etiology of their occurrence. An analysis of biochemical parameters tells us about the functioning of individual organs as well as the animals' metabolism. Knowledge of the values of blood parameters is of special importance because they allow us to gather more information on mouflons.

Enormous development of technology over the past two centuries has been associated with a considerable drawdown of non-renewable raw materials and an increase in the amount of harmful emissions. Thus, building direction in the field of construction implies a significant implementation of sustainability. The preference for environmentally friendly technology solutions is the right way to meet the sustainability trend. The main aim of this study was to analyze and verify selected construction systems of buildings designed for agricultural primary production in terms of their environmental impacts. The supporting construction systems of the comparative design variants was designed from a variety of material bases (concrete, steel, and wood). To evaluate environmental construction systems, the LCA methodology in mode “Cradle to Gate” was used. Parameters of sustainability related to the environmental impact were analyzed. These results could be a useful tool for the evaluation and comparison to an appropriate choice of the design option for an industrial building designed for agricultural primary production in terms of environmental impact.

Sustainability of cities is currently a much-debated topic. The trend in Central Europe we witness nowadays is that people are going back from the impersonal and restrictive conditions of tower blocks to the more natural and relaxed conditions of family houses. New approaches to urbanization in the context of the sustainability of cities can be characterized by their use of innovative technologies and energetically efficient and ecologically acceptable construction materials. Companies have substantially responded to this trend, meeting the demand by offering a wide range of solutions. Alongside the traditional and long-established construction materials (brick, concrete), including wood, companies are introducing modern, innovative, and viable construction alternatives. Modern methods of construction (MMC), to which modern houses based on wood belong, promote the idea and application of environmentally and energetically efficient constructions. Just as the construction process itself significantly contributes to the depletion of natural resources, the production of construction materials contributes to significant environmental pollution and greenhouse emissions (particularly CO2). Sustainability assessments of construction projects increasingly involve the use of methodologies which assess sustainability criteria throughout a product’s Life-cycle. For our analysis of suburban housing clusters designed to serve as family houses, we chose an actual family house construction completed using a modern construction system based on wood. For the sake of comparing the modern construction method, we created an alternative model of a construction based on a traditional masonry construction system. The main objective of this contribution is to analyze selected variants of constructions in terms of environmental and economic sustainability characteristics, as part of a broader assessment of permanent sustainability, by applying the life-cycle assessment (LCA) and life-cycle cost (LCC) methodologies within specified assessment boundaries. A partial objective of this contribution is to point towards the ways of applying the LCA and LCC assessment methodologies, such as in the decision-making processes involved in alternative investment strategies for the construction of urban clusters in the context of sustainability.

The construction industry has long been among the sectors with lower productivity and efficiency. In the framework of construction, the concept of sustainability is at the forefront. Basic elements of sustainability are environmental aspects, social and economic aspects associated with construction as such. The basic requirement to measure these factors is to set the criterions and draft a methodology for their evaluation. The aim of this paper is to present a methodology for assessing the effectiveness of buildings in the context of sustainability. The article also presents a preview of the evaluation of two wood-based construction technologies through the proposed efficiency assessment methodology in the context of building sustainability.

Quality parameters are important for achieving sustainability and prosperity. A range of new and innovative construction systems is currently being developed, presented as modern methods of construction (MMC), which have an ambition to improve the performance parameters of buildings throughout their life cycle. As for the implementation of modern methods of construction in Slovakia, assembled buildings based on wood seem to be the most preferred construction system. In the study presented in the paper, we searched for already built and occupied wood-based family houses. The residents’ attitudes towards such a type of buildings in the context with declared design and qualitative parameters of efficiency and sustainability are overlooked. The methodology of the research study is based on a socio-economic survey. Due to the large amounts of data collected through a questionnaire, only selected parts of the survey results are evaluated and discussed in the paper. The presented parts of the survey focus on two research questions. The first is aimed at determining the preferred parameters of wooden structures with future users and the second is aimed at evaluating the quality of buildings in view of users of existing wooden buildings. An expectations survey aims the determine the attitudes of users during their use of wooden buildings as one of the innovative technologies, MMC, and their view of the quality of construction and comfort while living in them.

Recent developments in the construction industry have brought more efficient and sustainable technologies, technological procedures, and materials. An example of this are modern methods of construction, which offer larger production volumes with a higher quality and shorter procurement time. The goal of those methods is to improve construction sustainability through quality improvement, customer satisfaction, shortened construction time, and reduced environmental impact. The main goal of this research is to demonstrate, by means of theoretical assumptions, surveys, and analyses, the sustainability of modern methods of construction based on wood. The work focuses on identifying the user criteria for construction sustainability. Selected user criteria of construction sustainability are applied in a socio-economic survey whose purpose is to determine how users perceive the efficiency of selected construction systems. We evaluate certain user parameters in the context of sustainability by relying on the users of buildings (family houses) which have already been built and compare the results with declared design parameters.

Ensuring hygiene and health protection is one of the basic construction requirements. Such requirements are examined when commissioning new constructions and examining defects in constructions already in use. One substantial defect is biocorrosion which represents a synergistic process with a complex variety of factors. It is caused by biochemical manifestations of various micro-organisms (micromycetes). Micromycetes producing mycotoxins therefore play an important role regarding the so-called ‘Sick Building Syndrome’ that has become a global problem nowadays. The case study presented here aims to demonstrate the effectiveness of the diagnostic methods used in assessing the presence of micromycetes in a building’s internal atmosphere and on the internal surfaces of a construction built using traditional construction methods. The methodology of comparing methods is based on their effectiveness, taking into account the identification of type and intensity of micromycetes presence in the air and on the material surfaces in the monitored areas.
