A self-seeding green roof, which connects to the surrounding parkland and riverfront, is also situated on the rooftop of the building. The green roof was designed into the museum building in order to reflect the building's larger theme of regeneration; with green rooftop intended to appear as nature fusing with ruins, showcasing the process of regeneration. The green roof also provides the building with some sustainability benefits; being an economical and efficient solution for stormwater management in the area, providing energy savings, and providing air pollution remediation. The roof was designed to mimic the urban development of the area, with the western portions of the rooftop closer to the rural areas of Ottawa designed to blend in with the surrounding parkland, while the eastern portion closer to downtown Ottawa features sloped concrete slopes that provide visitors a view into the museum from the rooftop.
