Neuroarchitecture in schools

Acoustics comes first

A 2022 review of primary school research found noise and reverberation impair speech perception, memory, attention and learning, with children especially vulnerable (Mealings 2022). Another review tied classroom acoustic parameters to speech intelligibility and learning outcomes, while noting that age, room type and measurement methods make universal thresholds hard to set (Minelli et al. 2022).

The mechanism is familiar from the office research. Low-level sound can disrupt memory even when nobody would call it loud (C. P. Beaman 2005), and speech you can understand is the most disruptive kind (Haapakangas et al. 2020). In a classroom, the speech is often the lesson from the next room.

Air and temperature

Reviews covering offices and schools find temperature and air quality can affect performance, with effects depending on the task and the exposure (Wargocki & Wyon 2017, Wang et al. 2021). A meta-analysis of mostly adult studies associated short-term CO2 exposure with lower cognitive scores (Fan et al. 2023).

A 2026 study with Italian middle-school pupils complicates this. In a lab classroom held at 800 or 2,000 ppm of pure CO2, the CO2 level made no difference to arithmetic. Sound changed response times only for pupils with medium noise sensitivity, and responses in the lab were faster than in their real classrooms (Matteo Pellegatti et al. 2026). The authors estimate they needed about 247 pupils to detect a CO2 effect, so this is not evidence that ventilation does not matter. It shows how little of the school evidence comes from children themselves.

The gaps

Neurodivergent pupils are barely studied in real classrooms. One image-based study found coherence predicted how much people liked an interior across groups including autistic participants (Vartanian et al. 2021). That is a starting point, not a design brief. Daylight, color and classroom layout are written about far more than they are tested with children. The corpus lists these as open questions on the gaps page.

Questions about classroom design and the brain

How does classroom design affect learning?

Acoustics has the clearest evidence. Noise and reverberation impair speech perception, memory, attention and learning, and young children are more affected than adults. Air quality and temperature also matter for school performance, though the size of the effect depends on the task.

Does CO2 in classrooms affect children?

Reviews of mostly adult studies associate higher CO2 with lower cognitive scores, with ventilation the likely real driver. A 2026 lab study with Italian pupils found no effect of pure CO2 at 2,000 ppm on arithmetic, but it was too small to detect a modest effect by its own estimate.

What is the best classroom design for autistic students?

The evidence is thin. One study of interior preferences found coherence predicted preference across groups, including autistic participants, but it used images rather than real classrooms. This is one of the clearest gaps in the field.
