Improved Workplace Ventilation Shown in Studies to Double Cognitive Function Scores
Because it’s expensive to heat and cool outdoor air drawn into a building, workspaces tend to be ventilated only enough to meet ASHRAE minimums or achieve a LEED credit. But air quality profoundly affects workers’ cognitive performance, and even modest increases in ventilation can yield productivity and health benefits that far exceed the cost, says Joseph Allen, assistant professor and director of the Healthy Buildings Program at the Center for Health and the Global Environment at Harvard T.H. Chan School of Public Health.
