OBJECTIVE To examine the role of fungi in the production of sick building syndrome. METHODS A 22 month study in the United States of 48 schools (in which there had been concerns about health and indoor air quality (IAQ). Building indoor air and surface samples, as well as outdoor air samples were taken at all sites to look for the presence of fungi or their viable propagules. RESULTS Five f...

Purpose A building's Indoor Air Quality (IAQ) has a direct impact on the health and productivity its occupants. Understanding effects of IAQ in educational buildings is essential both design construction phases for decision-makers. The purpose this paper to outline air quality occupants' performance, especially teachers students settings. Design/methodology/approach This study aims evaluate tea...

The aim of this study is to investigate the impact of surgical staff on the indoor air quality in a unidirectional ventilation Operating Theatre (OT). Experimental measurements of particles and microclimate were acquired at rest and in operational conditions. The real OT (operational) use was simulated by a sham hip arthroplasty. CFD simulations were carried out outlining the studied environmen...

BACKGROUND Maternal smoking can cause health complications in pregnancy. Particulate matter (PM2.5) metrics applied to second hand smoke (SHS) concentrations provide indoor air quality (IAQ) measurements and have been used to promote smoking behaviour change among parents of young children. Here, we present the qualitative results from a study designed to use IAQ measurements to help pregnant w...

BACKGROUND Poor indoor air quality (IAQ) and psychosocial problems are common in schools worldwide, yet longitudinal research on the issue is scarce. We examined whether the level of or a change in pupil-reported school environment (IAQ, school satisfaction, and bullying) predicts recorded sick leaves among teachers. METHODS Changes in the school environment were assessed using pupil surveys ...

A study on performances of different ventilation schemes provided by vertical and horizontal unidirectional air flow was carried out in a standard orthopaedic operating theatre (OT). Starting from our previous studies of a real OT under operating use conditions, in this research different air flow configurations, considering some air curtain solutions on the ceiling and at the sliding door alwa...

Healthy building design is an emerging field of architecture and engineering. Indoor air quality (IAQ) inevitable factor that should be considered in healthy due to its demonstrated links with human health well-being. This paper proposes integrate IAQ prediction into by developing a simulation toolbox, termed i-IAQ, using MATLAB App Designer. Within the users can input information layout wall-o...

Abstract Background Indoor air quality (IAQ) is a concern in kindergartens as children spend much of their time there. Yet, there shortage biological indicators needed for assessing IAQ. Thus, this study evaluated IAQ using transplanted lichen Usnea misaminensis indicator. Methods Lichen samples, collected from Bukit Larut, Perak, Malaysia, were exposed to indoor and outdoor environments an urb...
