How do you design green roofs?
Green roofs are on the up and up. And for good reason! They have many environmental, economic and social benefits. In addition to their aesthetic appeal, they can promote biodiversity, improve the insulation of buildings and retain rainwater. Recent research conducted by ecologists is improving our understanding of the conditions under which rooftop vegetation thrives and develops, and assessing the quality of ecosystem services provided by different types of roofs. We consider the factors behind the design choices for such ecosystems.
