Environmentally-friendly green roofs are not only good for the environment, but they can help improve employee concentration, a new study from Melbourne University has found.
In the study, published in the Journal of Environmental Psychology, 150 students were asked to press a key as a series of numbers repeatedly flashed in front of them on a computer screen, unless the number was three.
Midway through the task half the group was given a 40-second break in which they looked at a flowering meadow green roof and the others looked at a bare concrete roof.
The participants who looked at the green roof made fewer errors and had better concentration in the second half of the task.
