In Indonesia, sick building syndrome (SBS) and related health problems are suspected among the residents in emerging new urban houses constructed of modern materials without sufficient material standards or minimum ventilation rates. First, this study investigates current conditions indoor air quality (IAQ) newly high-rise apartments major cities contrast with traditional landed houses, so-call...

The paper presents a study aimed at investigating the indoor air quality (IAQ) and people’s perception regarding environment of schools public buildings in Timisoara. monitoring was performed during cold season, period January 2020 – February 2021. Six administrative edifices belonging to municipality were subject monitoring. An Andersen microbial sampler used enumerate numbers different kinds ...

The objective of this study was to investigate associations between indoor air quality (IAQ) in K-12 classrooms and student academic performance. During the years 2015–2017, various IAQ factors 220 US were measured seasonally, excluding summer. Measurements taken during occupied unoccupied times several within each school. Occupied measurements included carbon dioxide (CO2) formaldehyde concent...

(1) Background: Many schools and higher education settings have confronted the issue of reopening their facilities after COVID-19 pandemic. In response, several airflow strategies spanning from adding portable air purifiers to major mechanical overhauls been suggested equip classrooms with what is necessary provide a safe reliable environment. Yet, there are many unknowns about specific contrib...

Between the ages of 6 and 18, children spend between 30 42 h a week at school, mostly indoors, where indoor environmental quality is usually deficient does not favor learning. The difficulty delivering air (IAQ) in learning facilities related to high occupancy rates low interaction levels with windows. In non-industrialized countries, as cases presented, most classrooms have no mechanical venti...

IAQ monitoring studies have gained renewed interest post COVID-19. Furthermore, accessibility to the corresponding enabling technologies has improved considerably in terms of cost and requisite knowledge. This paper aims outline key decisions involved for researchers building managers alike seek implement their own environmental study using commercially available hardware software. To do so, th...

Global climate change and COVID-19 have changed our social business life. People spend most of their daily lives indoors. Low-cost devices can monitor indoor air quality (IAQ) reduce health problems caused by pollutants. This study proposes a real-time low-cost monitoring system for smart homes based on Internet Things (IoT). The developed IoT-based is portable provides users with data transfer...

With air quality being one target in the sustainable development goals set by United Nations, accurate monitoring also of indoor is more important than ever. Chemiresistive gas sensors are an inexpensive and promising solution for volatile organic compounds, which high concern indoors. To fully exploit potential these sensors, advanced operating modes, calibration, data evaluation methods requi...

Human health hazards can exist in swine confinement buildings due to poor indoor air quality (IAQ). During this study, airborne dust and ammonia concentrations were monitored within a working farrowing facility as indicators of IAQ. The purposes of this study were to assess the temporal variability of the airborne dust and ammonia levels over both a daily and seasonal basis, and to determine th...

BACKGROUND Relationships between indoor air quality (IAQ) found in schools and the allergic and respiratory health of schoolchildren have been insufficiently explored. A survey was conducted in a large sample of classrooms of primary schools in France to provide objective assessments of IAQ to which young schoolchildren are exposed in classrooms, and to relate exposure to major air pollutants f...
