been designed with 50 skylight baffles that poetically
disperse daylight into the space – into the building’s
core. The design and direction of the skylight baffles
influence the play of light and shadow taking place in
the building throughout the day and across the year.
The dynamic behaviour of daylight juxtaposed with
the design of the electric lighting’s intensity, direction
and colour temperature help to create the appearance
of changing ‘ornamentation’ in the skylight baffles, as
well as in the atrium and its adjacent spaces. On the
occasions when the daylighting is insufficient – largely
during evening hours and winter – the electric lighting
comes to its aid.
The concept for the design of the electric lighting
entailed creating lighting that partly supports the
daylighting during periods of limited natural light,
and partly contributes to the general electric lighting.
Likewise, the electric lighting has been designed to
accentuate the tectonics of the skylight, and to create
a welcoming and exciting atmosphere in the atrium
space as a whole.
The electric lighting has been planned using 10
different lighting scenarios, each programmed with a
specific dynamic lighting configuration. The different
colour shades shift in a slow tempo, characterised by a
soft and gradual transition from one shade to another.
Most of the scenarios work with white light nuances,
which span a spectrum from bluish light to neutral
white light, and finally to warm light in the form of
dark golden hues. The scenarios are programmed to
align with daylighting’s diurnal and seasonal rhythms,
as well as to demarcate special holidays.
As people spend more and more time in artificially
illuminated environments it becomes increasingly
important to develop strategies that ensure that these
environments positively stimulate our senses and
enhance our feelings of contact with nature. It is crucial
that architectural ideas and concepts employ strategies
for the use both of daylight and artificial lighting.
