From the citation:

"In the heart of San Francisco’s beloved Golden Gate Park, the California Academy of Sciences’ new LEED® Platinum-rated museum now hosts the largest green roof of any natural history museum in the world. ... For San Francisco, the green roof creates the most concentrated area of native wildflowers within the city."

The design was done by Renzo Piano Building Workshop, who is noted for achievement in the field of green roofs.

To drum up positive press for this effort, San Francisco put green roofs on bus shelters! Click here to read about it!
