Green walls and roofs are becoming more popular especially in Europe and some of North America’s bigger cities. Not only do they beautify buildings and offer visual impact, but plants also provide the air with ‘scrubbers’ and are key to reducing pollution and rainwater run-off, insulating buildings and providing habitat for wildlife. Vertical gardening can offset the impact of a concrete world, reduce the risk of localized flooding, reduce noise and even have a positive impact on our health. On the cost-saving end, according to recent studies, “a layer of vegetation can reduce heat loss from buildings, cutting the wind chill factor by 75% and heating demand by 25%.”
Start small like in this picture or create a vertical wall of fresh herbs affixed to the wall adjacent to your barbecue. Every little bit helps.
