The research represents the preliminary data of the monitoring of IAQ for improvement of Safety and Health Factor towards sustainable work environment in industry. The system were develop and using the computer application and the IAQ instrumentation such as IAQ meter and the TOXIC meter to getting the direct reading data. The data were transfer and evaluate by using the Visual Basic Software. ...

Indoor air quality (IAQ) is the problem that people increasingly pay attention to. With the development of Chinese railway undertaking, air-conditioned train is developing to the direction of higher speed and more comfortable. However, in China, people pay more attention to the temperature and the relative humidity in train compartments, but do not care for IAQ, so it leads to poor IAQ in train...

Effective and efficient ventilation is essential when improving energy performance and Indoor Air Quality (IAQ) of buildings. Reducing air permeability can considerably improve the energy performance of buildings; however, making the buildings more airtight may result in lower rates of natural ventilation which may in turn increase the risks of condensation and unacceptable IAQ. This study eval...

Indoor air quality (IAQ) influences the health of humans, the young and the old being generally more susceptible. In this study we examined how supply and demand of indoor air quality in dwellings are matched. On the supply-side, we evaluated ventilation systems, including natural ventilation, balanced ventilation, and adaptive systems. Two major healthrelated aspects are flexibility (both a se...

Recently, airtight envelope system has become popular in the design of office buildings to reduce heating and cooling loads. Maintaining allowable indoor air quality (IAQ) for such airtight buildings totally depends on mechanical ventilation systems. Subsequently, poor operation of the ventilation system in such office buildings causes ineffective removal of polluted indoor air, and displays a ...

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...

The issues of indoor air quality are complex and can be directly influenced by a number of system and building parameters. There are no universal solutions for every problem since there are numerous potential contaminant sources. They may originate from indoors and have a direct impact on indoor environmental quality, or they may originate from outdoors and be transferred by a mechanical or nat...

Dry and irritated mucous membranes of the eyes and airways are common symptoms reported in office-like environments. Earlier studies suggested that indoor pollutants were responsible. We have re-evaluated, by review of the literature, how low relative humidity (RH) may influence the immediately perceived indoor air quality (IAQ), including odour, and cause irritation symptoms (i.e. longer-term ...

BACKGROUND Indoor air quality (IAQ) is considered an important determinant of human health. The association between exposure to volatile organic compounds, particulate matter, house dust mite, molds and bacteria in day care centers (DCC) is not completely clear. The aim of this project was to study these effects. METHODS - STUDY DESIGN This study comprised two phases. Phase I included an eval...
