People who work in green buildings are more productive than those in other buildings, according to a recent study by researchers at the University of San Diego's Burnham-Moores Center for Real Estate and CB Richard Ellis, an international real estate services firm.
The study surveyed 154 green buildings, containing some 2,000 tenants, across the U. S. Five-hundred-thirty-four of the tenants participated, making the study the largest of its kind so far, reports GreenerBuildings.com.
Researchers looked at sick days and self-reported changes in productivity after tenants moved to a green building. For their work, the researchers defined a green building as one certified at any level of the U.S. Green Building Council's Leadership in Energy and Environmental Design LEED rating system or having an Energy Star label.
The researchers found that:
54.5% of those surveyed agreed that workers were more productive in a green building. (42.5% agreed with the statement,12% strongly agreed with the statement and 45% reported no change.)
45% reported employees had 2.88 fewer sick days, 45% reported no change and 10%of the respondents, some of those who had moved to an Energy Star building rather than a LEED-rated building, reported an increase in sick days. Researchers noted that there are no indoor air quality requirements for Energy Star buildings, unlike the LEED system, which includes IAQ standards.
