Green roofs for the birds
Ballistic Architecture Machine’s (BAM) concept for a green roof installation, called Biornis Aesthetope, is an aviary for migrating birds proposed for the 70,000 sq ft rooftop of Goldman Sachs in Lower Manhattan. Ornithologists at Harvard and Cornell Universities provided BAM guidance on the resting and nutritional needs for 12 species of birds, including diurnal raptors, songbirds and owls, whose migration paths along the Atlantic Coast Flyway bring them through New York City regularly. The structure is essentially a park for birds: a layer of mesh creates topography for perching and resting and is filled with an array of soil types, water sources, plants and insects.
