With the marked increase in the awareness of indoor air quality (IAQ) issues, facility managers are under more pressure than ever to recognize and resolve IAQ problems. They must understand both the sources of these problems as well as the various methods for handling them. This document has been developed to help facility managers improve their understanding of IAQ issues and provide guidance ...

Inside IAQ is distributed twice a year and highlights indoor air quality (IAQ) research conducted by EPA’s National Risk Management Research Laboratory’s (NRMRL’s) Indoor Environment Management Branch (IEMB) and other parts of EPA’s Office of Research and Development. If you would like to be added to or removed from the mailing list, please mail, fax, or e-mail your name and address to; Inside ...

In the current paper, the effect on Indoor Air Quality (IAQ) of two commercial acrylic-based paints were compared: one (Paint A) for indoor applications, the other (Paint B) for indoor/outdoor applications. Both were applied on an inert and on a real mortar substrate. The possibility of Paint B to passively improve IAQ was also investigated when adding highly porous adsorbent fillers, both as a...

BACKGROUND The complex hospital environment requires special attention to ensure healthful indoor air quality (IAQ) to protect patients and healthcare workers against hospital-acquired (nosocomial) infections and occupational diseases. The aim here is to recommend effective guidelines for the control and management of hospital IAQ. MATERIAL/METHODS The authors have done an extensive literatur...

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. ...

Air change rates (ACRs) and interzonal flows are key determinants of indoor air quality (IAQ) and building energy use. This paper characterizes ACRs and interzonal flows in 126 houses, and evaluates effects of these parameters on IAQ. ACRs measured using weeklong tracer measurements in several seasons averaged 0.73 ± 0.76 h(-1) (median = 0.57 h(-1), n = 263) in the general living area, and much...

Primary schools mostly rely on natural ventilation but also have an interest in affordable technology to improve indoor air quality (IAQ). Laboratory tests show promising results for dust reducing carpets and compact air filtration systems but there is no information available on the performance of these interventions in actual operating classrooms. An exploratory study was performed to evaluat...
