The COVID-19 pandemic highlighted the importance of indoor air quality (IAQ) and ventilation, which researchers have been warning about for years. During pandemic, studied several indicators using different approaches to assess IAQ diverse ventilation systems in spaces. To provide an overview these case airborne transmission through aerosols, we conducted a literature review, covered studies bo...

In our practice, clients increasingly approach us with complaints related to asthma and allergy triggers. These need to be addressed separately from many of the other exposure-related risks we are used to dealing with on a daily basis. There is more to IAQ than monitoring radon, heavy metals, VOCs, biologic contaminants and molds. In the interest of your clients, you may want to include another...

This study was done to investigate the relationship between Indoor Air Quality (IAQ) and prevalence of Sick Building Syndrome (SBS) in two different offices (old and new) in Selangor. Hundred and seventy workers were selected consist of 85 office workers for each building. Questionnaire based on Indoor Air Quality and Work Symptoms Survey, NIOSH, Indoor Environmental Quality Survey, 1991 was us...

The mitigation of indoor air pollution sources in printing facilities is crucial for ensuring healthy environments and protecting the health well-being employees. This study assessed severity different pollutant control strategies use 22 presses Zaria metropolis, Kaduna State. adopted a quantitative method. A checklist was used to characterize selected examine on 5-point Likert scale. instrumen...

Indoor air quality (IAQ) in educational buildings is a key element of the students’ well-being and academic performance. Window-opening behavior infiltration, generally used as sole ventilation sources existing buildings, often lead to unhealthy levels indoor pollutants energy waste. This paper evaluates conditions natural classrooms order study how climate affect For that purpose, impact infil...

Stricter energy efficiency requirements of buildings have raised concerns about their effects on indoor air quality (IAQ). We studied measured and perceived IAQ in three low-energy wooden test using ventilation levels (0.5, 1.0, 2.0 (dm3/s)/m2). measurements included VOC (volatile organic compounds) sampling continuous several indicators. Perceived (PAQ) was investigated with a sensory panel un...

background: in the past few decades, indoor air pollution (iap) has become a primary concern to the point. it is increasingly believed to be of equal or greater importance to human health compared to ambient air. however, due to the lack of comprehensive indices for the integrated assessment of indoor air quality (iaq), we aimed to develop a novel, fuzzy-based indoor air quality index (fiaqi) t...

Indoor Air Quality (IAQ) and sleep quality measurements over a period of two weeks were performed all night in 40 bedrooms Denmark during the heating season. In first week, bedroom conditions typical what participants would normally experience sleep. second asked to open doors or windows if they had been closed opposite. A change 95 th percentile measured CO 2 concentration by more than 200 ppm...

Window operation is among one of the most influential factors on indoor air quality (IAQ). In this paper, we focus modeling windows’ opening state in a real open-plan office with five windows. The IAQ was monitored over whole year along A k-Nearest Neighbor (k-NN) classification model implemented, based long time series both and outdoor environmental such as temperature relative humidity, CO2 c...
