The images for Figure 5 and Figure 6 are incorrectly switched. The image that appears as Figure 5 should be Figure 6, and the image that appears as Figure 6 should be Figure 5. The figure legends appear in the correct order. The correct Figure 5 and Figure 6 with legends, can be viewed here.

Figure 5. Recommended ventilation rates in classrooms by country [40–44].

* Denotes calculated value.

Figure 6. Correlation between the mean indoor CO₂ concentrations in naturally ventilated classrooms and the air flow (l/s per person).

Red line represents relationship between air flow and mean CO₂ concentration at steady state (defined by Equation 2). Adapted from M. Santamouris et al. (2008) [33].
