the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
Indoor Air Quality (IAQ) in libraries is influenced by the presence of specific factors which can impact on both paper storage as well as people health. Microclimatic conditions induce and support a biodiversity pattern involving environmental and anthropic microorganisms. We used a multidisciplinary monitoring model to characterize microflora biodiversity by Next Generation Sequencing (NGS). B...
Study of indoor air quality (IAQ) has received attention of the researchers and policy makers over the last several years due to its affiliation with the adverse health effects and occupants’ discomfort. This article focuses on the importance and need of IAQ studies in Indian rural and urban indoor environments. A number of questions in this context are posed and addressed, together with identi...
The reliability of making risk-based corrective action (RBCA) decisions using ASTM methods was evaluated. Indoor air quality (IAQ) testing results for 153 residential homes in 1998 at a site in Denver, Colo., were evaluated in this study. Decisions regarding groundwater remediation and indoor air mitigation in residences located over a shallow groundwater plume contaminated with chlorinated com...
Introduction Hundreds of millions of patients are affected by nosocomial infections worldwide each year, leading to significant mortality and financial losses for health systems. Maintenance of adequate indoor air quality Air (IAQ) at hospitals is critical to the prevention of these infections. Evaluation of IAQ can be performed by bioaerosol sampling and particle counting. The current study a...
There are many indoor pollutants in the residential buildings. High insulation and tightness in buildings in order to increase energy efficiency and to lower energy costs is led to the indoor air quality problems. To provide sufficient fresh air and to promote indoor air quality at acceptable level, it is needed to increase ventilation rate to overcome such pollutants. The aim of this paper is ...
Indoor air quality (IAQ) has been the object of several studies due to its adverse health effects on children. Methods. A cross-sectional comparative study was carried out among Malay children in Balakong (2 studied preschools) and Bangi (2 comparative preschools), Selangor, with the aims of determining IAQ and its association with respiratory health. 61 and 50 children aged 5-6 years were sele...
Indoor air quality (IAQ) and air temperature (T) have powerful effects on the efficiency with which work can be performed in schools and offices. Huge amounts of energy are used to keep these parameters constant at levels which represent a compromise between group average requirements for subjective comfort and energy conservation. Human requirements change with task requirements and from hour ...
Indoor air quality (IAQ) in the use of combustion appliances is important for adequate evaluation of air pollution health risks. Since people spend most of their time inside buildings, especially the elderly and children, their exposure to indoor air contaminants can increase health problems in the community. Combustion materials emitted from combustion space heating appliances in housing durin...
While a number of studies have addressed the economic cost associated with adverse health and productivity effects of poor indoor air quality (IAQ), few have addressed the value of economic expenditures and job creation associated with this industry. This article estimates that the annual sale of IAQ products and services is valued at $18-$30 billion and is associated with approximately 150,000...
