Ventilation systems are mainly responsible for maintaining the quality of indoor air. Together with thermal comfort maintenance systems, they create appropriate conditions for living, working, learning, sleeping, etc., depending on the type of building. This explains the high popularity of research in this area. This paper presents a review of articles published in the years 2020–2023, which are indexed in the Scopus database and found with keywords "ventilation" and "thermal comfort" in conjunction with the type of building or predominant activity. Finally, 88 selected works for five types of buildings were discussed, namely offices, schools, hospitals, bedrooms, and atriums. Data on publications are summarized in the tables, taking into account the publishing year, country of origin of the authors, and keywords. In this way, the latest directions in research were presented, and research groups dealing with this subject were highlighted. For each type of building, synthetic conclusions were presented, summarizing the results of the analyzed research. This review paper would be helpful for scientists and practitioners in the field of ventilation in order to organize knowledge and in a short time be up to date with the latest research showing how ventilation affects the quality of use of buildings by their users.

Swimming is a good form of physical activity that keeps swimmers fit and healthy. In countries with cold climates, swimming is allowed only indoors. Since adequate water and air parameters must be ensured in these buildings, they are very energy-consuming. In new buildings, modern solutions can be used, thanks to which technologically advanced energy-saving systems can be used. Unfortunately, in existing buildings, it is not always possible to make technical changes, or they are associated with high financial expenses. In this article, a method of in situ measurement of selected air parameters is proposed, on the basis of which it is possible to suggest scenarios for changes in the control of air technology and parameters in order to achieve energy savings. The easy measurement method was applied in a typical swimming pool building, and energy-saving measurements were taken on the first day to obtain a baseline. Seven scenarios were analyzed that would lead to a reduction in energy consumption without the introduction of new elements into the facility. The main task was to find a solution that ensured adequate thermal comfort in the building. Significant energy savings were achieved in each scenario: 6–47% compared to measured energy consumption. To improve the energy efficiency of swimming pools, especially in the current energy crisis related to the economic and political situation, all methods for reducing the energy demand are desirable. The proposed assessment method will allow for energy-consuming elements and allow for changes in the use of equipment in the swimming pool building. However, the main objective is to maintain the thermal comfort of swimming pool users, as no savings can be achieved at the expense of worsening the feeling of building users. [ABSTRACT FROM AUTHOR]

• The atrium can be used as an element of a mechanical ventilation system. • IES-VE was used to estimate possibility of using atrium to provide thermal comfort. • In buildings, artificial lighting should be regulated in daylight function. • <10% of the hours beyond thermal comfort were obtained during academic year. • Using the atrium as a heat buffer 22%primary energy was obtained. The form, attractiveness, functionality, and exterior appearance of buildings have been important considerations in architecture for centuries. Large common spaces, sharing of daylight, and the use of large glazing are also important. Combining many of these factors, buildings with atriums form a focal point, create a social meeting place, and contribute to the attractiveness of the building by providing a large open interior space. In cold and moderate climates, the atrium roof is important as the climate is often not conducive to outdoor activities. Using an IES-VE simulation, variants of a building in which the atrium was an independent element of the building or integrated into the ventilation system as a passive heater were analyzed. Additionally, two lighting systems were analyzed: on/off time-dependent control and daylight-dependent control (using dimming profiles for artificial lighting). Integrating the atrium into the HVAC system reduced the primary energy consumption for air heating by 17–22%. Using regulated lighting lowered the number of overheating hours. Factoring when the building was used (academic year), the atrium variants met thermal comfort requirements for 90% of its useful time, which did not occur when the atrium was not integrated. Therefore, integrating an atrium with an HVAC system can reduce energy consumption while providing thermal comfort to users. [ABSTRACT FROM AUTHOR]
