LONDON /1998 - 2002/
The “pebble-like” form of the building in the
end resulted from optimization of its energy
performance by minimizing the surface area
exposed to direct sunlight. The building’s
form is a deformed sphere, which has a 25%
smaller surface area than a cube of identical
volume, resulting in reduced solar heat gain
and heat loss through the building’s skin.
