The air quality of indoor spaces is the most significant parameter in providing a healthy living environment. Low indoor air quality (IAQ) leads to Sick Building Syndrome—one of the major reasons for labor loss in office buildings. The fundamental measure to ensure indoor air quality is ventilation, which includes two basic types: mechanical ventilation and natural ventilation. Natural ventilation is an exchange of stale indoor air with fresh outdoor air by means of a pressure difference due to wind and/or stack effect. Trickle Vents, known also as background ventilators, are natural ventilation devices which can be integrated into façades or window systems as an alternative to operable vents, specifically in high-rise buildings. The major design criteria of Trickle Vents are ventilation capacity, controllability, actuation, thermal insulation, air permeability, water tightness, climatic adaptation, security, and acoustic attenuation. Other important parameters in Trickle Vents design are positioning, equivalent area, and control strategy. This paper aims to review all these aspects, particularly with reference to building regulations and commercial products. Furthermore, simulation, experimental, monitoring, and survey studies of Trickle Vents are also discussed. This literature review is presented from the perspective of performance parameters, control strategies, positioning, etc., with an aim to provide a comprehensive overview of such technology.

<p><em>The number of buildings that use air conditioner (AC), causing a lack of air change rate from the outside into the room or vice versa that can reduce indoor air quality. A bad indoor air quality is often give rise to complaints on its occupants called the "Sick Building Syndrome" (SBS). The presence of ventilation is expected to improve air quality and increase user comfort and wellness rooms. Therefore, the research on the influence of natural ventilation against sick building syndrome (SBS) is needed. This research was conducted with quantitative-descriptive methods with direct measurements of temperature, humidity and vloumetric air flow rate on samples of objects namely RSND clinic waiting room on the 2nd floor. As for analysis is carried out descriptively based on recommended standards. The purpose of doing this research is to know the influence of natural ventilation to the indoor air quality towards sick buiding syndrome. The result of this research show that the temperature, humidity and the clean air needs of the room doesn’t meet the standarts, meanwhile the air change per hour meet the standarts on some spots. So, there is some influence of the use of natural ventilation that can improve the indoor air quality which is relating to sick building syndrome.</em></p>

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.

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.

Several studies on indoor air quality (IAQ) and sick building syndromes have been completed over the last decade, especially in cold countries. Efforts to make homes airtight to improve energy efficiency have created buildings with low ventilation rates, resulting in the build-up of indoor pollutants to harmful levels that would be otherwise unacceptable outdoors. This paper analyzed the infiltration rates, indoor temperatures, and variations in CO2, 2.5 μm particulate matter (PM2.5), and total volatile organic compound (TVOC) concentrations over the fall of 2021 in several homes in New England, USA. A relationship between outdoor and indoor conditions and ventilation strategies has been set using the results from blower door tests and actual indoor air quality data. Although all case studies lacked mechanical ventilation devices, such as those required by ASHRAE Standard 62.2, natural ventilation and air leakage have been enough to keep VOCs and PM2.5 concentration levels at acceptable values most of the studied time. However, results revealed that 25% of a specific timeframe, the occupants have been exposed to concentration levels of CO2 above 1000 parts per million (ppm), which are considered potentially hazardous conditions.

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. Sehingga dapat menyebabkan terjadinya Sick Building Syndrome (SBS) atau sindrom bangunan sakit. Tujuan peneltian ini adalah untuk mengukur gambaran kondisi kualitas udara di dalam ruangan non kumuh. Sampel pada penelitian ini adalah Kelurahan Pasteur RW6, Kecamatan Sukajadi yang dipilih berdasarkan kriteria yaitu termasuk kawasan non kumuh, serta partisipasi masyarakat yang tinggi. Metode Penelitian yang digunakan adalah cross-sectional. Hasil penelitian menunjukkan gambaran kualitas udara di dalam ruangan pada rumah tinggal non kumuh, kelembaban berada di atas standar yang dipersyaratkan, sehingga memicu tingkat pertumbuhan jamur yang melampaui batas normal. Parameter suhu berada dalam kategori yang dipersyaratkan, namun berdasarkan hasil temuan sebagian masyarakat kurang nyaman dengan suhu ruang pada rumah tinggal. Parameter Formadehilda dan VOC berada pada batas normal, hal tersebut diindikasikan karena sebagian besar masyarakat tidak menggunakan produk-produk kimia, jarang melakukan aktivitas merokok di dalam rumah, serta jarang menghidupkan mesin kendaraan bermotor di dalam rumah. Kata Kunci: kualitas udara di dalam ruangan, Sick Building Sindrome (SBS)
