Better Classroom Air Quality with Displacement Ventilation

displacement-ventialtion_halton_ravenscroft_belgian_schoolSeveral international studies have found that indoor air quality in schools remains poor. This causes an increase in symptoms and illness, shortens attention span, while good air quality can enhance children’s concentration and also teachers’ productivity. The most common indoor climate problems are inadequate ventilation and thermal comfort.

In a recent article on indoor air quality in classrooms Panu Mustakallio and Risto Kosonen compared different air distribution methods and their effects on air quality in the classroom using a fullscale laboratory test to measure their performance. In their article, “Effect of Air Distribution Methods on Classroom Air Quality” originally published at Indoor Air 2011 conference, Mustakallio and Kosonen found that the average indoor air quality in the occupied zone was best with displacement ventilation, which also produced very good thermal conditions. For best results they recommend placing diffusers in all four corners of the classroom.

Displacement ventilation is also incredibly energy efficient, which makes it an excellent choice for ventilation in classrooms.
