Green Roofs at the Solaire Building,
New York, New York, United States
Landscape architects Balmori Associates
collaborated with Pelli Clarke Pelli Architects
to integrate vegetated roofs and a hydrologi-
cal system into the Solaire Building, the fi rst
sustainable residential high-rise in the United
States. Two green roofs—a 5,000-square-foot
(464.5 square-meter) terrace on the nine-
teenth oor and a 4,800-square-foot (445.9
square-meter) roof on the twenty-eighth
oor—absorb rainwater and fi lter pollutants
from the excess runoff , which is collected in a
basement cistern together with the buildings
gray water.  is water is later reused to irri-
gate not only the Solaire roofs but local parks
as well.

merge architecture, urban setting, and land-
scape: Here the gleaming sculptural forms of
ventilation units that line a walkway of stone
pavers are continued by the buildings in the
distance. At the same time, in the dense ur-
ban fabric of lower Manhattan, greens roofs,
especially when clustered, contribute to the
environment by absorbing solar radiation
and improving air quality.

beds form terraces rising from the paths and
benches at the periphery of the roof.  e two
