“…Occupants may also need to take into account noise pollution and low air quality outside the buildings along with the security considerations especially in cities and crowded areas [ 117 ]. Filters are frequently included in MV systems, which may remove or dilute particulates from external air [ 118 ]. Table 7 illustrates the comparison of the type of building by type of ventilation in the assessed papers within the repository.…”

“…Furnaces powered by solid fuel have been shown to have a harmful effect on indoor air quality [26,43]. Constructing a self-made, dual-heating system without the proper tools and knowledge creates a risk that the extraction of contaminants may be worsened and that they may be released into the household instead of being expelled from the house.…”

“…CO 2 is an additional contaminant that, in high doses, can influence human decision-making performance [22]. It is often measured alongside thermal comfort indicators, such as the air temperature and relative humidity, to determine the quality of the indoor air as well as the effectiveness of ventilation systems, making it an important trace contaminant [23][24][25][26].…”

Due to rising energy costs, there is a trend to return to conventional heating systems powered by solid fuel. A rise in the combination of new and old energy sources is creating unintended dual-fuel heating systems. These systems combine an old solid-fuel furnace and a new gas furnace. Usually, the old furnace was meant to be replaced by the new one and their cooperation was never intended when installing the new heating system. The occupants decided to leave the old system in fear of a rise in prices of gas or electricity or temporary problems with their supply. The study focuses on such a system and its influence on indoor air quality and thermal comfort. A series of dynamic measurements with an IoT remote sensor array in a chosen household was conducted to evaluate the behaviour of the system as well as effects on the indoor environment. Sensors measured the CO2 concentration and thermal profile in a household when using a dual-fuel heating system consisting of an old wood furnace from the 1980s and a recently installed new gas furnace. The results showed that none of the heat sources posed a threat to the occupants. Contaminants were safely removed by the exhaust systems of the furnaces. The thermal comfort, however, was influenced more by the wood furnace where fluctuations in the temperature were noticed, especially during the night. The gas furnace maintained a stable temperature that was more suitable for the occupants.

“…In recent decades, mechanical ventilation systems have been increasingly used to meet ventilation requirements and dilute indoor-generated pollutants. Numerous studies (Kang et al, 2021;Tian et al, 2020;Yassine et al, 2012) have examined the effects of residential mechanical ventilation systems on IAQ, thermal comfort, and/or energy use. Mechanical ventilation systems with heat recovery (MVHR) have become more popular as an energyefficient solution to provide good IAQ during the heating season (Clarke, 2019).…”
