Associations of Cognitive Function Scores with Carbon Dioxide, Ventilation, and Volatile Organic Compound Exposures in Office Workers

What the study found

Cognitive scores were higher under lower-VOC and higher-ventilation conditions than under conventional office conditions.

Limitations

Short exposure periods; simulated office; combined environmental changes complicate attribution to one factor.

Neurodesign interpretation

The important design signal is interaction: material emissions and ventilation form one exposure system. Finish selection can alter the ventilation burden required to keep a room cognitively supportive.

Possible design implications

Select low-emitting materials and design for adequate outdoor air delivery rather than treating ventilation and materials as separate wellness topics.
