Many Rodale Institute staff members cooperated in recent days to construct the farm’s first green roof, providing an early crop this spring. The innovative installation pushes the edge of the chosen living-roof technology due to its relative steep roof angle.
Using a type of low-growing and maintenance-free sedum, the living system is carefully designed to outlast a typical roof, while slowing runoff from severe rainfall. It also provides a cooling effect to the building—and the surrounding air—in summer. So says William Heasom, P.E., president of Down to Earth Design Foundation, a non-profit organization focusing on engineering for regeneration.
Check out the cool slideshow of a few awesome living roofs.
