In the analysis published in Indoor Air, the team looked at indoor air, thermal, acoustic, and lighting conditions. The collected evidence from 21 studies showed that the indoor environmental quality can contribute to the quality of learning. Sufficient evidence confirmed that poor indoor air, thermal, acoustic, and lighting conditions negatively influence the quality of learning due to discomfort and impaired mental and physical health of students. On the other hand, optimal conditions can create an environment in which students feel more alert and pay more attention.

Study results also indicated that indoor environmental quality can affect short-term students' academic performance, with a preference for a relatively cool, bright, and quiet environment and in ambient air with low carbon dioxide concentrations.
