Study finds green roofs improve concentration:

A new study from Melbourne University has found that environmentally-friendly green roofs are not only good for the environment, they also improve employee concentration.

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 during 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.

Dr Kate Lee, Head Researcher, said, “We know that green roofs are great for the environment, but now we can say that they boost attention too. Imagine the impact that has for thousands of employees working in nearby offices. This study showed us that looking at an image of nature for less than a minute was all it took to help people perform better on our task.”

The study deliberately used a 40-second “micro-break” to mirror the mini breaks which happen spontaneously throughout the day. “It’s something that a lot of us do naturally when we’re stressed or mentally fatigued. There’s a reason you look out the window and seek nature, it can help you concentrate on your work and to maintain performance across the workday.

“This study has implications for workplace well-being and adds extra impetus to continue greening our cities. City planners around the world are switching on to these benefits of green roofs and we hope the future of our cities will be a very green one.”

More and more rooftop gardens are appearing in Melbourne and Sydney, including The City of Melbourne offices on Little Collins Street and the M Central apartment building in Pyrmont, Sydney.
