Retrospective, introspective, circumspec-

The building’s architecture reflects the
“open space” concept in Bonn’s Haus der
Geschichte. Three barrel vaults, covered
entirely in glass, form the main design
element and supply the exhibition
rooms with daylight.
The glass elements contain two prism
systems. Sun protection prisms regulate
the indoor atmosphere, preventing the
rooms from heating up – even on hot
days. Deflection prisms ensure evenly
distributed, glare free illumination. The
effect is light flooded interiors with a
pleasant temperature, and perfect illu-
mination of the exhibits from all sides.

11. PLANNING

latitude 47.9 º, longitude 12.6 º
Planning.
Top quality lighting solutions cannot be
purchased “off the rack”. Every building
and every room has different optical
properties and different lighting require-
ments – particularly in terms of natural
light. This is why we develop an individu-
al, customised Siteco daylight solution
for each site.
For planning purposes, we use results
from theoretical calculations, as well as
actual measurements. When calculating
complex requirements – e.g. when the
interior decoration elements and surface
texture have to be taken into considera-
tion – we utilise lighting simulations in
addition to computer aided design.
