This report is the response to a policy request submitted by DG Environment to the EC Knowledge Centre for Biodiversity (KCBD) through the KCBD ticketing system. Green roofs and green walls are proven, scalable solutions for restoring nature in cities while delivering measurable benefits for climate resilience, biodiversity, energy efficiency and human well-being. Evidence from case studies across Europe shows that extensive green roofs dominate current implementation, while intensive roofs and vertical greening systems offer higher biodiversity and social value when supported by appropriate design, governance and maintenance.

Provides detailed policy implementation guidance for the EPBD, EED, UWWTD and the NRL for national levels.

Explains the Design, Installation and maintenance as well as policy, technology and Market aspects of Biosolarroofs and Solar Green Roofs. Provides detailed Case studies.

Includes the latest research results and case studies from across Europe. The newly compiled data highlights the numerous advantages of integrating green roofs, green walls, and indoor vertical greenery into our built environment.

Technical guideline that sets an implementation framework for design, planning, installation and maintenance of different solar green roofs.

Combining biodiversity focussed green roofs and walls with an experimental wood building, creating an open neighbourhood laboratory hotspot for the green city transformation.
