ISO 7730:2025 Ergonomics of the thermal environment

What the study found

Provides analytical methods for thermal comfort assessment using PMV/PPD and related criteria.

Limitations

Population-average thermal models do not capture all individual or adaptive responses.

Neurodesign interpretation

Population comfort models are useful because their limits make the residual individual variation visible.

Possible design implications

Use model outputs as one layer, not as proof that every individual will be comfortable or cognitively optimized.

Why it stays in the corpus

Retain as the international thermal-comfort reference alongside ASHRAE 55.
