“…An optimal indoor microclimate is a prerequisite for the well-being and health of its inhabitants. It is important to note that the concept of an optimal microclimate can be a very subjective assessment, unless we talk about it only in terms of standard requirements (Coggins et al, 2022). Thermal comfort is closely related to an optimal microclimate.…”

“…Alongside health care facilities, buildings for the education of children and young people are the most monitored buildings in this regard. Therefore, in these buildings, compliance with CO 2 limits is stressed (Bogdanovica et al, 2020), of course, together with other monitored variables such as the indoor air temperature and relative humidity (Coggins et al, 2022). The issue of indoor environmental quality is mainly addressed in primary school buildings, where air quality measurements are carried out within the framework of professional publications (Skotnicova et al, 2019) (Talukdar et al, 2020), including proposed measures leading to their improvement.…”

Today in addition to the design of structures, layout solutions, and the design of suitable materials, the modern construction industry also addresses meeting the requirements for the energy performance of a building, with which the topic of the quality of the indoor environment is fully intertwined. Comfort in the use of buildings, and especially the provision of thermal comfort, is a fundamental aspect in the design of technical equipment systems, where a properly selected system regulating the indoor environment can affect b oth t he e nergy p erformance o f t he building and the quality of the indoor environment. One of the important factors is the air quality, where the main factor that af-fects the indoor environment is the concentration of CO2, whose value affects the biological functions of the human organism. The subject of this research is an evaluation of the indoor air quality in a kindergarten because children are more sensitive to environmental influences.

In Poland and other countries in Central Europe, residential buildings from the second half of the 20th century dominate, which have recently undergone deep thermomodernisation. Research on the retrofitting of residential buildings has focused mainly on energy efficiency, with only a few studies on indoor air quality. The aim of this study was to present a comparative analysis of the impact of five ventilation scenarios (three natural and two mechanical) on CO2 concentration and energy demand for heating and ventilation in residential spaces of a multi-family building located in Poland. The analyses were based on the results of building performance co-simulation using the EnergyPlus and CONTAM programs carried out under dynamic conditions with a 5 min time step for the entire heating season. The calculations took into account the instantaneous occupancy variability of twenty apartments. In the buildings equipped with new tight windows, the natural ventilation system provided extremely low air exchange (on average 0.1 h−1) and poor indoor air quality (average CO2 concentration at the level of 2500 ppm). Opening windows to ventilate the rooms generated a multiple increase (up to 8 times) in heating demand during these periods, but average CO2 concentration was on the level of 930 ppm. The use of mechanical ventilation was profitable both in terms of energy savings (at the level of 50%) and improvement in the indoor air.

“…In last decades, exposure to pollutants generated in the indoor environment has been a serious concern for the scientific community [2][3][4][5], given that people spend more than 90% of their time in different interior spaces (dwellings, offices, schools, restaurants, malls, etc.) [6][7][8][9][10][11].…”

“…Numerous worldwide studies specify that many health problems such as respiratory, cardiovascular, neurodevelopment and cognitive diseases [3,5,[11][12][13], are associated with the indoor air pollutants (IAPs), only in Europe, an annual burden of 2.1 million DALYs (because of cardiovascular, lung cancer and respiratory diseases) being attributed to exposure to indoor air pollution [11]. At present, carbon dioxide (CO2), ozone (O3), particulate matter (PM2.5), formaldehyde (HCHO) and total volatile organic compounds (TVOC) are the most common pollutants in the indoor environment of buildings and are among some of the many health relevant pollutants, being measured in different type of buildings, often at concentrations exceeding maximum permissible values [4,[10][11][14][15].…”

Indoor Air Quality (IAQ) assurance is done mainly through the air exchange between interior and exterior. Lack of adequate ventilation of indoor spaces causes poor air quality and a higher incidence of sick building syndrome (SBS), which is manifested by affecting the comfort and wellbeing in the indoor spaces. Ensuring high energy performance buildings and indoor air quality is efficiently approached by limiting emissions from sources, by partial neutralization of the pollutants or by smarter ventilation. The concept of smart ventilation was developed to ventilate properly while reducing energy loads, allow for the provision of grid services, and promote associated renewable power integration. The above-mentioned information can be obtained by the air quality modelling, using mathematical approaches to predict the way pollutants behave in a certain environment or time scale. The paper presents the results obtained by mathematical modelling of indoor air quality, by including the transfer of pollutants from external sources and variable indoor emissions. The considered pollutants are ozone (O3), particulate matter (PM2.5), formaldehyde (HCHO) and carbon dioxide (CO2), due to the significant adverse effects on human health and their different preponderantly sources: indoor, outdoor or both indoor and outdoor. The main goal of our researches is the reducing of the amount of energy that ventilation uses while maintaining or improving IAQ.
