Sick Building

The indoor air quality (IAQ) in office buildings should be assessed for public health concerns as it relates to work performance and productivity. Therefore, this paper aims to assess the IAQ in a university office building. From this investigation, the level of contaminated indoor air is examined, the significant causes and contributing factors of contaminated indoor air are determined and a recommendation to improve the existing condition has been proposed. The physical parameters measured include air temperature, air velocity, relative humidity, and concentrations of carbon dioxide (CO2), carbon monoxide (CO), sulphur dioxide (SO2), and also air particles. It was found that the number of air particles of 0.5 μm in diameter is about 197,748 particles/m3, while air particles of 5.0 μm in diameter is around 534 particles/m3. The collected data were then compared with a questionnaire and IAQ standards. In conclusion, the indoor air quality within the multi-storey central office building of Universiti Tun Hussein Onn Malaysia (UTHM) is acceptable and suitable for occupation even though there were countable symptoms of Sick Building Syndrome (SBS) among its occupants.

Sick Building

Sick building syndrome (SBS) is a collection of symptoms experienced by buildings occupants such as headaches, mucous, membrane irritation, respiratory problems and fatigue. A building is claimed to have SBS if more than 20% of building occupants experience symptoms. Poor indoor air quality contributes to SBS in the building. This study aims to investigate the correlation between indoor air quality and SBS symptoms in 1st and 2nd floors of the Post office building in Bandung. The study used quantitative methods with a cross sectional study design. Data collection was carried out using particle counter, thermometer, lux meter and anemometer to measure the indoor air quality, while the questionnaire utilized random sampling technique with 119 respondents. The results of the primary data were compared with the air quality standard from Minister of Health No. 1077, 2021. The results of the Statically Compare Means and Independent T-test showed that the p-values of the temperature on the 1st floor and 2nd floors were 0.437 and 0.000, respectively. Meanwhile the p-values of PM10 and PM2.5 on the 1st and 2nd floors were 0.005 and 0.290 and 0.004 and 0.364, respectively, and the p-values of the lighting on the 1st and 2nd floors were 0.002 and 0.015. It indicates that there is a significant relationship between concentrations of PM10 and PM2.5 on the 1st floor with SBS symptoms and the temperature and humidity on the 2nd with SBS symptoms. Since 29 peoples (24% of the building’s occupants) experienced SBS, the building was considered to have a significant potential to cause SBS to its occupant.

Sick Building

This study was conducted to assess the indoor air quality (IAQ) level of buildings in Universiti Teknologi Malaysia (UTM). The buildings were randomly selected and represent the old building (>10years) and new building (<10 years). The IAQ physical parameters assessed are temperature, relative humidity and air velocity. Meanwhile, the IAQ chemical contaminants studied are carbon dioxide (CO2), carbon monoxide (CO), formaldehyde (HCHO) and total volatile organic compound (TVOC). The results indicate that the old building has good IAQ level compared to the new buildings. The statistical test shows, there is an association between some IAQ physical parameters and the buildings’ ages (p<0.05). On the chemical contaminants, the measurement shows that the concentration of CO2 and HCHO for all studied buildings exceeds the Malaysian acceptable exposure limits. The results also show there is no association between demographic factors and sick building syndrome (SBS) symptoms. The level of workplace condition and SBS symptoms existed in each selected faculty’s buildings was also analyzed. The recommendations for the minimum number of years for maintenance of the indoor conditions have also been suggested based on the indoor air quality guidelines from Malaysia and Singapore. Finally, the appropriate technical and management approach has been suggested based on the some concepts.

This study assesses the interior air quality and infective factors in a hospital in Turkey to provide data about air quality to protect hospital workers. This study measured indoor air quality in eight different locations in a hospital, including particulate matter (PM2.5 and PM1), carbon dioxide, carbon monoxide, temperature, humidity and microbiological matter. The highest PM2.5 and PM1 concentrations were in emergency service, and the highest CO2 was measured in the paediatric clinic. The poor interior air quality results are the most important cross-sectional data. For all participants, the prevalence of eye, upper respiratory tract, lower respiratory tract, skin and non-specific sick building syndrome symptoms were 23.0%, 40.7%, 22.5%, 36.3% and 63.7%, respectively. When sick building syndrome symptoms and environmental factors were investigated, skin symptoms increased 1.82 times in areas with stagnant air flow (p = 0.046; OR = 1.823; 95% CI: 1.010–3.290). Non-specific symptoms increased 2.17 times in locations with dry indoor air (p = 0.039; OR = 2.176; 95% CI: 1.041–4.549). Hospital workers are exposed to conditions that may increase the risk of a variety of sick building syndrome symptoms. Although the air quality measurements were not above the recommended limits in the hospital, long-term exposures should be considered for those experiencing sick building syndrome-related symptoms.

Abstract: This research was initiated by the factors of poor indoor air quality conditions. So that it can cause Sick Building Syndrome (SBS) or sick building syndrome. The purpose of this research is to measure the picture of air quality conditions in non-slum rooms. The sample in this study was Pasteur Village RW6, Sukajadi District which was selected based on criteria, namely including non-slum areas, as well as high community participation. The research method used was cross-sectional. The results showed an overview of indoor air quality in non-slum dwellings, humidity was above the required standard, thus triggering fungal growth rates that exceeded normal limits. The temperature parameter is in the required category, but based on the findings, some people are uncomfortable with the room temperature in the house. The Formadehilda and VOC parameters are within normal limits, this is indicated because most people do not use chemical products, rarely smoke in the house, and rarely start motorized vehicles in the house.Keywords: Indoor Air Quality, Sick Building Sindrome (SBS) Abstrak: Penelitian ini diawali oleh faktor kondisi kualitas udara di dalam ruangan yang buruk.

Examining the indoor air environment of public venues, especially populated supermarkets such as Co-Ops in Kuwait, is crucial to ensure that these venues are safe from indoor environmental deficits such as sick building syndrome (SBS). The aim of this study was to characterize the quality of the indoor air environment of the Co-Ops supermarkets in Kuwait based on investigation of CO2, CO, NO2, H2S, TVOCs, and NMHC. On-site measurements were conducted to evaluate these parameters in three locations at the selected Co-Ops, and the perceived air quality (PAQ) was determined to quantify the air’s pollutants as perceived by humans. Moreover, the indoor air quality index (AQI) was constructed for the selected locations, and the ANOVA test was used to analyze the association between the observed concentrations among these environmental parameters. At least in one spot at each Co-Op, the tested environmental parameters exceeded the threshold limit set by the environmental agencies. The PAQ for Co-Op1, 2, and 3 are 1.25, 1.00, and 0.75 respectively. CO2 was significantly found in an association with CO, H2S, and TVOCs, and its indoor-outdoor concentrations were significantly correlated with R2 values ranges from 0.40 to 0.86 depending on the tested location.
