DELHI, India, Dec. 4, 2015 /PRNewswire/ -- Improved indoor environmental quality doubled participants' scores on cognitive function tests, according to a new study by researchers at the Harvard University T.H.Chan School of Public Health's Center for Health and the Global Environment, SUNY Upstate Medical University and Syracuse University. The study was released in India today. Primary support for the study came from United Technologies (NYSE: UTX) and its UTC Climate, Controls & Security business.
"The Impact of Green Buildings on Cognitive Function" study found that employees' cognitive performance scores averaged 101 percent higher in green building environments with enhanced ventilation compared to a conventional building environment.
"When it comes to the decision-making ability of green building occupants, intelligence is in the air," said John Mandyck, United Technologies Chief Sustainability Officer. "We know green buildings conserve natural resources, minimize environmental impacts and improve the indoor environment, but these results show they can also become important human resource tools for all indoor environments where cognitive abilities are critical to productivity, learning and safety."
"The payback for improved indoor environmental quality far outweighs the investment, considering that more than 90 per cent of the costs associated with a building are related to the people who work within it once construction is completed," he added.
"While outdoor air quality of air has become increasingly important in many major Indian cities, the results of this study signal the importance of also improving indoor air quality, not only to minimize indoor air pollution but also to improve cognitive function and productivity," said Arun Bhatia, managing director, UTC Climate, Controls & Security, India.
The double-blind study evaluated the cognitive performance of 24 participants who experienced conditions in a laboratory setting that simulate those found in conventional and green buildings, as well as green buildings with enhanced ventilation. Researchers measured cognitive function for nine functional domains, including basic, applied and focused activity levels; task orientation; crisis response; information seeking; information usage; breadth of approach; and strategy.
The largest improvements in cognitive function test scores occurred in the areas of crisis response, information usage and strategy.
The Center for Health and the Global Environment at the Harvard Chan School and SUNY Upstate Medical are launching a second phase of research, which will move from the lab into real buildings across the United States. This research will also be supported by a gift from United Technologies.
