Employees in offices with enhanced ventilation systems and low levels of chemical air pollutants appear to outperform workers from offices with inferior air quality. The researchers also found the average performance scores of these employees fell as carbon dioxide levels increased to levels that commonly occur in indoor settings. Lead author Dr. Joseph Allen comments, “These results suggest that even modest improvements to indoor environmental quality may have a profound impact on the decision-making performance of workers.”
