Few would dispute that living walls have got the wow-factor. But what about the pound-factor?
Can you put a price-tag on a green wall’s impact? As an increasingly weighty body of scientific evidence shows, they purify the air, encourage biodiversity and regulate temperature. And as they change with the seasons, they also stimulate the senses. But is it possible to specify a green wall’s payback period?
With research showing that 50% of the world’s population live in cities, urban living is now the norm. By 2050, the UN predicts this trend to increase by 40% which means 6.65bn of the projected 9.5bn people on Earth will be living away from nature. This will be a triumph for industry but a fatal blow to rural living. The trick is marrying the two and this is where vertical greening comes in.
