LCA environmental parameters of green roofs: a comparison of results and an overview on data quality

This paper presents the environmental performance of six greenroof solutions currently available on the Italian market and highlight the lack of information, both environmental and thermal, that are necessary to run a complete and specific assessment. The paper also aims to demonstrate how LCA could support producers in designing more efficient and low impact greenroofs, selecting materials based on their environmental profile over their life cycle and taking into account potential reuse of recycle at the end of life.
