Persistent monitoring of Indoor Air Quality (IAQ) within and around buildings and structures is critical to reduce risk of indoor health concerns. Specifically, IAQ issues in large integrated buildings may stem from inadequate ventilation and/or faults in the complex HVAC systems that together with control and communication systems can be considered as complex Cyber Physical Systems (CPSs). We ...
Abstract Assessment of indoor environmental quality has recently moved to a combined methodology both measurements and questionnaire surveys. In this study, we have used data from the national survey Swedish housing stock, BETSI, conducted in 2007/2008, during heating season. The study included, among others, measurement selected air pollutants an extensive on occupants’ perception their dwelli...
Inuit infants have extremely high rates of lower respiratory tract infection (LRTI), but the causes for this are unclear. The aims of this study were to assess, in young Inuit children in Baffin Region, Nunavut, the feasibility of an epidemiologic study of the association between indoor air quality (IAQ) and respiratory health; to obtain data on IAQ in their housing; and to identify and classif...
Smoking in public places is a hot debate presently in Europe. A number of legislative bodies in Europe have already made policy decisions on the issue of smoking in public places. Scientific evidence relating to this debate has been reported in a diverse range of publications such as BMJ, Indoor air and the BSJ. On inspection much of the reporting concludes negatively on the performance of vent...
Abstract Indoor Air Quality (IAQ) assurance is done mainly through the air exchange between interior and exterior. Lack of adequate ventilation indoor spaces causes poor quality a higher incidence sick building syndrome (SBS), which manifested by affecting comfort wellbeing in spaces. Ensuring high energy performance buildings efficiently approached limiting emissions from sources, partial neut...
Abstract Energy building design today aims to ensure thermal comfort and indoor air quality; this concern has been increased, given the recent SARS-CoV-2 pandemic. The proposed work investigates effect of increased natural ventilation on energy requirements, ensuring low CO 2 levels acceptable Indoor Air Quality (IAQ) in general. case hospitals was chosen because stringent IAQ requirements they...
Controls for indoor air quality (IAQ) in schools are not usually performed throughout Europe. The aim of this study was to assess the effects of IAQ on respiratory health of schoolchildren living in Norway, Sweden, Denmark, France and Italy. In the cross-sectional European Union-funded HESE (Health Effects of School Environment) Study, particulate matter with a 50% cut-off aerodynamic diameter ...
Many ice rink arenas have ice resurfacing equipment that uses fossil fuel as power. The combustion byproducts are a major source of contamination. Ventilation along with other pollution source control measures is the most widely applied strategy to lower the contaminant level below the threshold limit and maintain acceptable indoor air quality (IAQ). A computational fluid dynamics (CFD) model h...
PURPOSE To analyze and characterize a multidisciplinary, integrated indoor air quality checklist for evaluating the health risk of building occupants in a nonindustrial workplace setting. DESIGN A cross-sectional study based on a participatory occupational health program conducted by the National Institute of Occupational Safety and Health (Malaysia) and Universiti Putra Malaysia. METHOD A ...
