The present study aims at investigating the indoor air quality (IAQ) in selected households in the urban slums, as well as a control site, in Delhi, the capital city of India. The study includes assessments of associated respiratory health effects and Sick Building Syndrome (SBS) on the occupants living in inefficiently designed houses with poor ventilation. The comparative analysis of concentr...

Roof problems, especially roof leaks, not only disrupt building operations, but can also contribute to the occurrence of severe internal Indoor Air Quality (IAQ) problems (Oliver 1997; Rivin 2001; Haverinen, Vahteristo et al. 2003). One of the well-accepted causes of roof leaks is the lack of roof maintenance (Lounis, Vanier et al. 1998a). The out-of-sight, out-of-mind nature of a roof’s locati...

To develop and evaluate housing strategies interventions for improving indoor air quality (IAQ) at a city or national scale, stock IAQ models are required. Without such models, reliable prediction of residential pollution concentrations exposures various spatial-temporal scales cannot be achieved. address the areas not covered by past review articles in performance modelling, this paper present...

Recently, many studies have focused on studying indoor air quality, especially with the outbreak of COVID-19, which is one reasons for increased need to improve quality. Many ideas and applications are available incorporate nature into buildings quality (IAQ) thus secure a higher percentage natural ventilation pollution reduction. One these use "breathing walls" (BWs), envelope components based...

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...

Indoor air quality (IAQ) is a growing concern, as people spend about 80–90 percent of their time indoors.It known that IAQ in office buildings influences people’s health. Employment agencies are one the most important institutions,where more than 1000 visit and hold interviews everyday. Measurements were made order to assess staff visitors building exposed to,and findings compared WHO ARSHAE st...

Children’s exposure to particulate matter (PM) is of great interest because it can cause adverse health effects, including asthma, and decreased lung function. The purpose this study was determine the levels PM in low socio-economic status homes Omaha, Nebraska. Between October 2018 September 2019, we collected ambient air samples from 30 homes, which 70% had at least one asthmatic child. Sampl...

background:: this study developed a smart co 2 detector, which attach to the general ventilation system to reduce the gas level. methods: indoor air quality measurement was performed in five selected rooms between january 2015 to february 2015 using tsi q-trak tm indoor air monitor 7575. the perceived indoor air quality conditions was gathered using questionnaires adopted from the industrial co...

This work evaluates the integral effect of thermal comfort (TC), indoor air quality (IAQ) and Draught Risk (DR) for desks with four personalized ventilation (PV) systems. The numerical study, winter summer conditions, considers a virtual chamber, desk, different PV systems, seats manikins. Two configurations, two upper lower terminal devices (ATD) distance between them are considered. In this s...
