Classrooms

Recently, studies have shown that the classroom environment is very important for students' health and performance. Thus, the evaluation of indoor air quality (IAQ) in a classroom is necessary to ensure students' well-being. In this paper the emphasis is on airborne concentration of particulate matter (PM) in adult education rooms. The mass concentration of PM10 particulates was measured in two classrooms under different ventilation methods in the University of Reading, UK, during the winter period of 2008.

This work examines the applicability of comfort criteria, based on a heat balance model and on anadaptive model, in naturally ventilated classrooms. The adaptive opportunity of students are limitedduring the lesson time, while they are free during the lesson breaks. The field study was conducted byphysical observations, survey questionnaires and behavioral observations. Both field measurementsand subjective surveys were performed at the same time during the regular lesson period.
