Associations of Cognitive Function Scores with Carbon Dioxide, Ventilation, and Volatile Organic Compound Exposures in Office Workers: A Controlled Exposure Study of Green and Conventional Office Environments

Research Findings - (Strength: Strong)

This study compared outdoor air ventilation of 20 cubic feet per minute per person versus 40 cubic feet per minute per person. The study subjects performed 18% better on cognitive tests when in exposed to the higher ventilation rate.
