Green roof is able to expand the area of the natural landscape. It can serve as the integral part of healthy and balanced micro ecosystem that supports biodiversity. Planting the rooftops helps to avoid significant temperature fluctuations inside the buildings: green roofs absorb excess heat in the summer and protect against overcooling in winter.
