Employees working in certified ‘green’ buildings are likely to have better cognitive abilities, fewer ‘sick building’ symptoms and higher sleep quality scores than those working in non-certified buildings, according to a new study conducted in the US.

The study, carried out by the Harvard School of Public Health and the State University of New York (SUNY) Upstate Medical University, investigated the health effects of working in in a green building environment with enhanced ventilation, compared with a conventional building environment.

Researchers studied 109 workers at 10 different buildings in five cities across the US, and found that those working in green-certified buildings had 26% higher cognitive function test scores than those in similarly high-performing buildings that were not green-certified.

Moreover, green-certified building workers had 73% higher crisis-response scores; 44% higher applied activity levels – which reflects ability to gear decision-making towards overall goals; and 38% higher focused activity level scores – which reflects the capacity to pay attention to tasks at hand.
