The Impact of Buildings on Cognitive Function

Harvard T.H. Chan School of Public Health

What if indoor air quality could improve decision making?

Our Healthy Buildings research program is interested in how buildings can be leveraged to improve human performance. We’ve embarked on a multi-year research endeavor aimed at examining links between indoor air quality and cognitive function, in a series of studies, we call “The COGfx Study”.

Study 1:
In the Lab

In Study 1, the research team found cognitive function test scores doubled when participants were in simulated green building environments with enhanced ventilation as opposed to conventional building environments.

Study 2:
In the United States

In Study 2, the research team examined real-world building environments to determine if the green certification of high-performing buildings could result in higher cognitive function scores and health benefits for occupants.
