Managing thermal comfort in classrooms
Thermal comfort is the sensation of feeling too hot, too cold, or just right. Maintaining a thermally comfortable classroom environment can improve students' learning performance.
We all want students to enjoy comfortable and healthy learning environments.
Thermal comfort varies from day to day due to factors such as air movement, radiant temperatures, humidity and the prevailing external conditions. Hence, the comfort expectations of staff and students will adapt accordingly to this experience of external temperature.
Indoor air temperatures for occupied learning spaces are expected to be between 18 and 25 degrees Celsius for most of the year. However, this may not always be possible because elevated temperatures may persist for a few hours a day during warmer weather.
We suggest that during periods of warmer weather (e.g. summer), schools do the following to help manage the internal temperature of classrooms:
- open windows and doors to allow cross ventilation
- switch on ceiling fans or mobile fans where available to increase air movement and evaporative cooling
- pull blinds on windows to block out the sun
- ensure access to drinking water to make sure staff and students are hydrated
- encourage staff and students to wear lighter clothing
- utilise shaded outdoor areas and
- reduce the use of devices that create heat.
More guidance on indoor air quality and thermal comfort requirements can be found on the Designing Quality Learning Spaces (DQLS) page.
Boards of Trustees are responsible for the health and safety of students and staff on school grounds. If parents have any concerns about the environment that their child is learning in, we encourage them to contact the school in the first instance.
