The effects of surface air movement on material emissions were investigated experimentally. A field study was carried out to understand the characteristics of surface air movement in real rooms, and a velocity-controlled test chamber was designed and built, based on the field study results, to provide a uniform mean air flow and boundary layer condition over the test area. An extensive experimental study on the effects of air movement on material emissions was carried out, under different mean flow velocities and turbulence fluctuations, by using the small velocity-controlled test chamber.
In order to design an environment-conscious house, it is desirable for summer indoor environment, to re-examine thermal conditions warmer than thermal comfort. The role of air movement is important, as it reduces the magnitude of discomfort. This paper discusses the comfort produced by air movement considering two main sensations; coolness and strength of movement, based on results obtained by a series of experiments carried out with five male and five female subjects.
The research described in this paper is part of a project aimed at improving energy costs and the indoor environment of atrium buildings. Tracer gas techniques were used to assess the ventilation performance in terms of air distribution and contaminant migration patterns and to measure the air infiltration rate of a three-storey atrium. This atrium serves as an entrance to a large office-laboratory complex.
