We’re advocating for what we call Buildingomics – a new approach that examines the totality of factors in the building-related environment that influence the human health, well-being and productivity of people who work in buildings. Through Buildingomics’ multi-disciplinary approach, we aim to better understand the building-related factors that influence health in buildings and unlock the ability to optimize buildings for cognitive function and health.”

Better Buildings= Better Sleep + Better Health + Better Cognitive Function

Building Environment

Blue-enriched Light (such as daylight)

during the day has been shown to improve sleep quality at night (Viola et al. 2008)

Sleep quality Scores 25%Higher

scores were associated with 2.8% higher cognitive function scores the next day


A larger contrast between daytime and nighttime light exposure results in more melatonin, a hormone that promotes sleepiness, being released in the evening (Takasu et al. 2006)

Sleep quality Scores 6.4%Higher

in high-performing1, green-certified2 buildings vs. high-performing, non-certified buildings

In addition, 26% Higher Cognitive Function Scores in high-performing, green-certified buildings vs. high-performing, non-certified buildings

Sick Building Symptoms

in high-performing, green-certified buildings

Participants reported 30% fewer sick building symptoms

in high performing, green-certified, buildings vs. non-certified buildings

Workers in green-certified spaces had fewer complaints about

Air Movement
Air Dryness/Humidity
Chemical, Tobacco or Other Odors

And also reported greater


With the amount of daylight and electrical lighting in their work spaces

Green-certified buildings have
better thermal conditions

Cognitive Test scores were

5.4% Higher

within the thermal comfort zone vs. working outside the thermal comfort-zone3

High-performing non-certified buildings were more frequently outside of ASHRAE's thermal comfort zone due to higher humidity
