“…Surprisingly, they found that perceived air quality could be high even when VOC levels were high, suggesting that VOCs are not a defining feature of perceived air quality. This type of finding indicates the importance of the suggestion by Pei et al [48] that an occupant's perception of air quality should be incorporated into any traditional physical air quality monitoring programme. The findings from the current study would support this suggestion.…”

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.

“…The need for air ventilation in buildings is to provide the required oxygen for occupants' well-being, dilute and neutralize polluted air, and ensure the removal of excessive heat as well as moisture within a space [1,29]. Building ventilation is employed in buildings to achieve the building's heating and cooling tasks [30].…”

“…Clean breathing air can be achieved through the removal of pollutants from within the building's interior space by ensuring a sufficient outdoor air exchange through ventilation. Proper ventilation in buildings, therefore, acts by diluting air contaminants and removing them from the indoor space, thereby improving the quality of air for building users [1]. A building design without adequate ventilation would have a great impact on indoor air quality (IAQ), temperature, humidity, and airflow as a result of inherent pollution.…”

Building indoor spaces requires constant access to fresh air for occupants’ health, well-being, and performance. Clean breathing air can be achieved through the removal of pollutants from within the building’s interior by ensuring a sufficient outdoor air exchange rate. This review set out to create a clear understanding of recent developments in indoor air quality (IAQ) studies and their relationship to sick building syndrome (SBS) impacts on occupants’ health and well-being, as well as the role architectural design plays in promoting a healthy indoor environment. It also provides support information as well as existing state-of-the-art practices in IAQ and SBS in office buildings, with a particular focus on monitoring, assessment, and space configuration. The information available here would provide building professionals, particularly architects, with the potential for incorporating design and the development of guidelines for the control of SBS-related environmental parameters in order to create a healthy and comfortable office indoor environment.

“…This can lead to discomfort and higher energy consumption [4]. Various studies have focused on assessing IAQ in offices, addressing aspects such as perceived air quality (PAQ) [5], the relationship between IAQ and productivity, and sick building syndrome (SBS) [6], as well as the link between ventilation and energy consumption [7].…”

Building tight for minimizing building energy consumption and related carbon emissions might negatively affect indoor air quality (IAQ) if this is not correctly designed and evaluated during operation. To address this concern, a post occupancy evaluation study was conducted in a recent large office building in the Autonomous Province of Bolzano (Italy). The aim of the study was to collect evidence from a relevant case study and use it as a basis to define a standardized strategy for continuous monitoring of a larger portfolio of office buildings. Additionally, carbon dioxide (CO2), particulate matter (PM2.5, PM10), total volatile organic compounds (TVOC), air temperature, and relative humidity were recorded 24/7 for a 5-week period in winter 2023. Detailed spot measurements of VOCs and aldehydes were also carried out. Perceived air quality (PAQ) was evaluated through satisfaction surveys which covered various factors influencing PAQ including 14 potential sources of dissatisfaction. A cross-modal approach allowed for a comprehensive examination of the different domains (thermal, visual, acoustic, and IAQ) on PAQ. Measured contaminants’ levels were below recommended limits. Overall, participants were neither satisfied nor dissatisfied with PAQ, and possible related sources of dissatisfaction were elements such as the relative humidity. Sick building syndrome (SBS) selfreported symptoms such as dry skin and itchy eyes confirmed potentially too low relative humidity levels.
