TOO HOT TO LEARN?
24°C. Then 25°C. Then 26°C.
At what point does a warm classroom become a problem?
We looked at the temperature data from 105 teaching spaces across three schools to find out.

Temperature data collected by Twinview sensors across 105 teaching spaces in three schools reveals how often classrooms exceed 24°C, and what this can tell us about the spaces students and teachers use every day.
Measure what’s happening — Collect temperature data from real teaching spaces over time
Spot overheating — See when and where classrooms exceed 24°C
Understand the patterns — Identify trends in temperature across different spaces and times of day
Make informed decisions — Use clear evidence to understand where further investigation or action may be needed
105 Teaching Spaces Monitored
Temperature data collected across classrooms and teaching spaces.
3 Schools Analysed
Data gathered across three schools to understand patterns of overheating.
24°C+ Real Temperature Data
Analysing how often teaching spaces exceeded 24°C.
TEMPERATURE ISN’T STATIC
It’s not just about the average temperature
A classroom might look fine on paper, but averages can hide what is really happening.
Our data shows how temperatures can rise throughout the day, with some teaching spaces reaching uncomfortable levels even when overall conditions appear acceptable.
Looking at temperature over time reveals a much clearer picture.
OVERHEATING ISN’T THE SAME EVERYWHERE
Some classrooms feel the heat more than others
Overheating isn’t necessarily consistent across an estate.
Temperature data from the 105 teaching spaces highlights differences between rooms, showing where temperatures rise more frequently and where hotspots may be developing.
The question isn’t just “Are our classrooms too hot?” It’s “Which ones, when, and by how much?”
