Key Findings
- 01Poor indoor air quality was primarily linked to closed windows and doors during winter.
- 02Thermal discomfort predominantly occurred in summer due to high indoor temperatures.
- 03A well-defined ventilation protocol is essential for balancing both indoor air quality and thermal comfort.
Application
Design takeaway
Implement dynamic ventilation strategies that encourage appropriate window and door usage based on external and internal environmental conditions to maintain both air quality and thermal comfort.
How to apply
When designing or retrofitting educational spaces, incorporate intelligent ventilation controls or guidelines that promote optimal airflow throughout the year, considering both air quality and thermal comfort.
Project actions
- 01Consider how users interact with ventilation controls in your design.
- 02Investigate the trade-offs between different environmental factors in your design project.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Large sample size of classrooms and participants.
- +Longitudinal data collection over a full year.
Limitations
The study's findings are specific to the Mediterranean climate and may not be universally applicable. The complexity of human behavior is difficult to fully capture.
Reliability & validity
The extensive on-site measurements and large sample size contribute to the reliability of the findings. The use of clustering analysis for scenario characterization adds a layer of validity to the identification of key conditions.
Think critically
How can design interventions proactively encourage beneficial occupant behaviors related to ventilation, rather than relying solely on user education?
Design Principles
"Adaptive ventilation is essential for optimizing human comfort and health in naturally ventilated spaces."
Designers and engineers must consider the interplay between occupant behavior and environmental conditions to create healthy and productive learning spaces. Neglecting one aspect can negatively impact the other, leading to suboptimal user experiences.
What This Means for Your Design
In schools with windows that open, keeping them shut in winter makes the air bad, and it gets too hot in summer. A good plan for opening and closing windows helps keep the air fresh and the temperature just right.
How to use in your project
- 1.Use this research to justify the importance of considering both air quality and thermal comfort in your design proposal.
- 2.Reference the findings to support your design decisions regarding ventilation strategies.

Paragraph starter
This study by Miao et al. (2023) underscores the critical need to balance indoor air quality and thermal comfort in naturally ventilated educational buildings. Their findings indicate that user behavior, such as closing windows in winter, significantly degrades air quality, while high summer temperatures lead to thermal discomfort. The research emphasizes that a well-defined ventilation protocol is paramount for achieving optimal conditions, suggesting that designers should prioritize adaptive ventilation strategies that respond to seasonal changes and occupant needs to create healthier and more productive learning environments.
