The article presents the results of field studies of air quality depending on mobile sources of pollution. Studies of the carbon monoxide concentration was conducted for the climatic conditions of the South of Western Siberia. The object of the study was residential buildings. The studies were conducted under unfavorable wind speed. Processing of experimental data allowed to obtain the calculated dependences of dimensionless concentration of carbon monoxide (II) on the height of building’s facade under emissions from highways. According to the results of research a nomogram was constructed to determine the optimal air intake height of buildings located near roads of various traffic intensity. Research results and given recommendations allow considering external sources of pollution when designing ventilation of a building.

Ventilation Systems

Building air-tightness has been increased to make energy efficient buildings. However, various indoor air quality issues can be caused by high building air-tightness because it allows low air and moisture transmission through building envelop. In order to solve and prevent these issues, mechanical ventilation systems can be used to control the indoor humidity level. The purpose of this paper is to evaluate the performances of the Relative Humidity (RH)-sensor based auto-controlled centralized exhaust ventilation systems to manage indoor air quality and thermal comfort of multi-family residential buildings in South Korea. A series of field tests were performed for different target zones and for various moisture source scenarios. As a result, it was found that the auto-controlled centralized exhaust ventilation systems were able to control indoor air quality and to maintain the zones thermal comfort faster than the baseline cases that did not operate exhaust vents. The results presented in this paper can show the potential and the feasibility of the auto-controlled centralized exhaust ventilation systems for multi-family residential buildings in South Korea. It is expected that the results presented in this paper would be useful for building owners, engineers, and architects when designing building systems.

Set Up

The study is devoted to improving the quality of life in Siberian medium and small settlements through a range of noise control solutions. Field studies carried out in 2019 and 2020 revealed a problem of noise pollution in these settlements caused by highways cutting through their planning structure and industrial facilities set up in the immediate vicinity of residential buildings. Modern methods of protecting residential buildings against noise were considered and the noise control experiences of historical settlements were reviewed. The consideration of available engineering solutions along with cultural heritage restoration and reconstruction technologies suggested a range of actions to protect residential buildings located in the immediate vicinity of highways against noise.

The Impact

Along with the thermal modernization process of old residential buildings, there has been a significant increase in the air tightness of apartments, which may contribute to the deterioration of the safety of users and rescue teams in a fire. The main goal of this study was to investigate the impact of the air tightness of an apartment on fire growth and temperature variability. In the work, an experimental method was applied. Two full-scale fire tests were carried out, one in a sealed apartment and the other in unsealed one. The temperature was measured by thirty-two thermocouples. Two thermal imaging and video cameras were also used to evaluate a temperature field as well as flame and smoke height. Based on the analysis, conclusions have been formulated. It is noteworthy that the highest temperatures and significant increase in pressure were obtained in a sealed apartment, but dangerous and critical conditions regarding firefighters’ safety were achieved faster and persisted much longer in an unsealed one.

The Impact

Traffic–induced vibrations may constitute a considerable load to a building, cause cracking of plaster, cracks in load–bearing elements or even a global structural collapse of the whole structure [1-4]. Vibrations measurements of real structures are costly and laborious, not justified in all cases. The aim of the paper is to create an original algorithm, to predict the negative dynamic impact on the examined residential building with a high probability. The model to forecast the impact of vibrations on buildings is based on artificial neural networks [5]. The author’s own field studies carried out according to the Polish standard [6] and literature examples [7-10] have been used to create the algorithms. The results of the conducted analysis show that an artificial neural network can be considered a good tool to predict the impact of traffic–induced vibrations on residential buildings, with a sufficiently high reliability.

Air Tightness

Renewal windows and doors in residential buildings is a big trend at present. On windows, as products, a number of strict requirements that are fulfilled during laboratory testing are placed. What is the real condition after installation in the construction? The subject of this paper is the assessment of the tightness of replaced windows and doors in apartment situated in a prefabricated apartment building. For the diagnosis measuring devices Blower Door was used. At the same time scanning by infrared thermocamera was done. Critical points of leakage were detected. In the conclusion possibilities of solving leading to ensuring the required tightness are described.
