Abstract
There has been a growing interest in investigating indoor air quality levels
in complex buildings such as primary schools to assess the impact of
students’ performance and well-being. Concerns are raised towards
identifying the parameters that negatively affect indoor air quality in
classrooms. Poor indoor air quality is expected to play a vital role in the
prevalence of allergic and respiratory diseases.
Indoor air quality in schools plays an important role in assessing student
exposure to air pollution as children are more sensitive when exposed to
unhealthy air because they breathe more air than their body weight and at
a faster rate.
This study shows measurements of carbon dioxide (CO
2
), particulate
matter (PM2.5) and volatile organic compounds (VOCs) on indoor air
quality for classrooms in a primary school in Cairo, Egypt, and discusses
the concentration levels of these parameters on indoor air quality. Readings
of the measurements were applied on an air quality monitoring system that
is developed by the author. This study raises awareness towards
considering indoor air quality in schools designs with the purpose to
minimize health risks and improve students’ Learning performance. This
research follows the deductive method. It hypothesizes that school designs,
typologies, and configurations affect the extent of natural airflow and
ventilation within classrooms, and thus air quality.
These factors are:
1- Orientation of the classrooms
2- design configuration of school buildings (clustered, linear -single
or double loaded corridor-, central around courtyard)
3- Effect of surroundings such as distance from the street - the
operation type of the surrounding buildings.
Therefore, measurements of the air quality parameters will be taken on
several different designs, typologies and configurations in order to:
1- Evaluate the current situation in some primary educational schools
in downtown Cairo
2- Measure the effect of these parameters on air quality
3- Compare these measurements with the international guidelines.
