“…A review of indoor air quality indexes by Pourkiaei and Romain [64] indicated that objective measurements rather than subjective surveys had become more prevalent in air quality research. Future work should try to readdress this balance, given the importance of non-objective environmental and behavioural components on a person's perception of their air quality and their physical and mental health.…”

Kazakhstan is in Central Asia and is the ninth-largest country in the world. Some socially vulnerable segments of the Kazakh population residing in subsidised social housing have experienced a range of problems due to the low quality of housing construction and its planning. Poor indoor environmental conditions in social housing contribute to occupants’ comfort, health, and general well-being. This study assessed social housing residents’ health and quality of life, focusing on their perceived indoor air quality and thermal comfort satisfaction. A cross-sectional survey in Kazakhstan was conducted to test the effects of environmental factors on social housing residents’ health and satisfaction. Four hundred thirty-one responses were analysed, and the SF12v2 questionnaire was used to measure the health-related quality of life. Multiple regression analysis showed that air quality negatively predicted the respondents’ physical (PCS) and mental (MCS) health. In addition, age, smoking, and employment status had a significantly negative effect on PCS, while education level had a predictive positive effect. Thermal conditions negatively predicted only MCS, as well as alcohol consumption. Next, the air-conditioning control factor had a negative effect. In contrast, low air circulation, low humidity, high solar gain, temperature imbalance, duration of the residence and alcohol consumption had a significantly positive effect on overall satisfaction with the temperature. The odour sources from tobacco, furniture and external sources were predictors of respondents’ overall air quality satisfaction, along with the duration of the residence, alcohol consumption and smoking status.

“…With the rapid development of the economy and the continuous improvement of people's living standards, the requirements for the indoor environment are becoming more stringent. From the initial focus on thermal comfort to the concern of indoor humidity conditions, increasing attention has been given to the quality of indoor air quality (IAQ), such as the concentration of indoor particulate matter with a diameter of less than 2.5 µm (PM 2.5 ), and carbon dioxide (CO 2 ) [4,5]. In the summer, to pursue a more comfortable and cleaner office environment, the most commonly used methods are using air conditioners for indoor cooling [6], employing air purifiers to purify indoor polluting particles [1,7], and utilizing fresh air systems to supply fresh outdoor air to dilute the indoor CO 2 .…”

As concerns about indoor air quality increase, air purifiers and fresh air systems are increasingly being used in conjunction with air conditioners in office buildings. To study the synergistic effects of multisystem joint operation on indoor air quality, this study used a combination of experimental and simulation methods to study the indoor particulate matter with a diameter of less than 2.5 µm (PM2.5) and carbon dioxide (CO2) concentrations under different operation conditions. The purification time and the PM2.5 concentration distribution under different conditions were compared with the condition in which the purifier was used alone. The results showed that the purification time required for the condition that the air conditioner runs together with the purifier was shortened by 15.2%. When the fresh air system is running together with the purifier, the purification time can be reduced by 30.4%. It was reduced by 32.6% when the three systems were operating at the same time. The PM2.5 concentration distribution under the joint operating condition was much more even than that under the condition in which the purifier was running alone. To analyze the impact on the CO2 distribution, the CO2 distributions under different joint operations were compared. The results show that the fresh air system can effectively dilute CO2 below 1000 ppm in 30 min. The air conditioner and purifier could help to mix the indoor air to provide a much more uniform indoor CO2 distribution.

“…Similarly, detailed reviews of some metrics of healthy buildings have been carried out, including indoor air quality (IAQ) [ [29] , [30] , [31] ], indoor environmental quality (IEQ) [ 32 , 33 ], occupant productivity [ 34 ], human comfort [ 35 ], ventilation technology [ 36 ], rating system [ 16 ] and engineering control precautions [ 37 ]. For example, Pourkiaei and Romain discussed the IAQ index used for different purposes [ 29 ]. Saini et al provide a comprehensive review of indoor air quality monitoring systems [ 31 ].…”
