The ingress of natural light within this project
had to be carefully considered particularly in relation to the Congress
Hall and Lobby, which were essentially underground. In contrast the
office building with its large atrium volume enjoyed an abundance of
natural daylight penetration.
dpa worked closely with the
local project architect Irena Sakellaridou, Athens, who in turn was
working in association with Mario Botta. It was important for their
to be harmony between natural light and the artificial lighting installation.
Within the atrium the flying glass bridges are
bathed with natural light in the daytime from above via a large roof
light. In the evening the reverse of this is achieved with integrated
lighting to the underside of the bridge, lighting through the frosted
light fixtures are integrated within the vertical portions of the Congress
Hall and Lobby skylights so that the daytime lit opening can be replicated
at night, so as to express this architectural feature throughout the
