How does indoor air quality impact the

health, productivity and cognitive performance

of office workers around the world?

Study Factors

The COGfx Study 3 took a global approach to explore the role of buildings in public health, examining the indoor environment and its effect on office workers in urban commercial buildings across the globe.

Focus Areas

Through COGfx Study 3, researchers examined the associations between cognitive function and ventilation, which affects indoor concentrations of carbon dioxide (CO2) and fine particulate matter (known as PM2.5). This included occupants' ability to think, reason and respond.

Ventilation

Ventilation refers to the rate of air exchange in buildings. Ventilation rates can impact the concentration of CO2 and other common gases.

PM2.5

PM2.5 refers to tiny particles in the air. They can can travel deep into your respiratory tract, enter your blood and deposit in your brain.

Real-Time Data

Using real-time environmental sensors in urban commercial buildings and a mobile app that was custom developed for this study, researchers collected data and administered momentary assessments of cognitive function, health and satisfaction within the indoor environment.
