Building on the first two COGfx studies, COGfx Study 3: Global Buildings aims to create the first-ever cohort of green buildings for a comprehensive, multi-year study of the specific factors in a built environment that influence human health and productivity. Harvard University researchers from the T.H. Chan School of Public Health invite buildings from all over the world to be a part of this ground breaking research. The study team will provide office workers in these buildings who sign up for the study:

  • A sensor to track the indoor environmental conditions at their desk
  • A wearable device to track sleep and physical activity

These devices will integrate with the new ForHealth app, allowing study participants to complete surveys and cognitive tests.

  • By extending the study to all buildings, everywhere, the Harvard research team hopes to understand how the indoor environment affects office workers around the world.
  • With a large, diverse sample of buildings and people followed over time, the team will investigate both individual-level and building-level effects.
  • Changes in building performance will be tracked over time and compared to occupants’ health and productivity.

New research from the Harvard T.H. Chan School of Public Health, called The COGfx Studies, is changing the green building discussion by unveiling its impact on human performance. Study 1: Indoor Environmental Quality set the methodology. Study 2: Buildingomics took the research out of the lab, connecting green buildings with occupants’ health and productivity. Now, Study 3: Global Buildings scales the research globally.

The Lab The U.S. The World

3-Year Global Study

Findings become available BEGINNING IN 2018

Real-Time Data

Data will be collected over several months using MOBILE TECHNOLOGIES to study the impact of green building on cognitive function

Office workers in participating buildings volunteer to take part.

Harvard researchers receive anonymous, real-time data through the For Health app.
