The integration of daylighting element into sustainable building design presents a significant opportunity to reduce energy consumption while improving indoor environmental quality. This study focuses on the performance assessment of passive daylight transport systems, with an emphasis on their thermal and optical characteristics. Various configurations of tubular daylighting devices were analyzed using simulation-based methods, considering material properties, geometrical parameters, and hygrothermal conditions o...

External Thermal Insulation Composite Systems (ETICS) are a key component in achieving high energy performance in building envelopes. Despite their thermal efficiency, ETICS facades are frequently affected by biological surface degradation caused by microbial growth, primarily algae and fungi. This phenomenon is closely linked to hygrothermal dynamics, where moisture availability, condensation events, and limited surface drying play a critical role. The presented study maps the conditions contributing to biologica...

Ventilation plays a key role in maintaining the indoor environmental quality of buildings. This contribution focuses on the significance of ventilation intensity as a crucial indicator of air quality within buildings. The aim is to analyze the impact of ventilation intensity on various aspects of the indoor environment, including thermal comfort, pollutant concentrations, and overall occupant comfort. The research is centered around methods for measuring ventilation intensity and ways to optimize this value to ach...

A healthy indoor environment is becoming an increasingly important issue. As the use of various materials in inhabited interiors increases, so does the concentration of harmful volatile organic compounds (VOCs) in these spaces. The actual trend of reducing energy consumption in buildings, such as by using perfectly sealing windows and doors, contributes to this increase. Consequently, people moving around in these interiors experience a rise in health problems due to the elevated concentrations of VOCs. This study...

One of the tasks defined in the basic principles of sustainable building construction is to ensure a quality indoor environment and the health and wellbeing of the building’s users. Especially in the current epidemiological period, people spend more than 90% of their time indoors. In almost every indoor environment (IE), there is a certain number of ornamental houseplants. In most cases, these are ornamental plants with leaves or flowers. These plants give us aesthetic impressions and improve the well-being of bui...

The paper deals with the monetization assessment of the environmental impacts of current systems of flat roofs. Monetization techniques are commonly used for evaluation of the negative environmental impact. Environmental impact can be defined as a change in the environment, whether favourable or unfavourable, which is wholly or partly due to human activity. Very often, environmental impacts are characterized by climate change such as global warming, acidification, eutrophication, ozone depletion, etc. With regard ...

The emissions of indoor nitrogen oxides have increased during the last period. Thorough knowledge of the interactions of individual influencing factors to nitrogen oxides pollutions in the indoor working environment provides guarantees of comfort, hygiene, and health for future manufacture buildings performance and production. A comprehensive assessment of the environmental safety of the working environment through appropriate analyses of transfer processes, impact rates, and interaction relationships must become ...

The bearing capacity of steel members and their cross-sections is influenced by geometrical - dimensional and material - strength variations, which are randomly variable. The actual design standards take this into account by characteristic or nominal values yield strength, design cross-sectional dimensions and partial reliability factors of the material to ensure adequate reliability of the proposed structures. There is still insufficient knowledge of the actual geometrical and material deviations and the results ...

The current building sector is undergoing major changes due to increased pressure to reduce energy consumption in buildings and increase the share of renewable energy sources. Modern systems and technologies can save energy, but also affect the quality of the indoor environment. In terms of air quality, attention was paid to the exterior, such as emission limits, etc. The indoor environment is generally a physical reality that surrounds the living organism with which it interacts, and which constantly contributes ...

There are many studies focusing on indoor air quality in primary and secondary schools. Nevertheless, studies in nursery schools are still few. Concentrations of indoor air pollutants are typically 2-5 times higher, and occasionally 100 times higher than outdoors. Children spend more time in nursery and preschools than in any other indoor microenvironment besides home. It is generally assumed that preschool students are more susceptible to the adverse effects of poor indoor air quality (IAQ) than elementary or mid...

Indoor environment is considered to be a basic requirement for human health and well-being. Concentrations of indoor air pollutants are typically 2-5 times higher, and occasionally 100 times higher than outdoors. The condition and performance of the ventilation have a significant impact on indoor air quality. People are ordinarily exposed to high concentrations of pollutants in indoor environments. The consequences of low ventilation rates include elevated levels of carbon dioxide and other air contaminants indoor...

A major pollutant in indoor air are volatile organic compounds (VOCs) emitted from materials and building products The indoor surface materials are considered to be studied as the principal sources of indoor air pollution. The source control is the most practical approach to improve the indoor air quality. The measure for indoor pollutionпїЅs decreasing seems to be the effective control of volatile organic compounds and indoor odors. The perceived indoor air quality in four rooms with various flooring materials wa...
