Above: Delicate design giving light and transparency
Valencia has always been a city of
many parts: the centre of the Spanish
Levant – a focus for agriculture and
trade – it is one of the most impor-
tant seaports in Spain. Today, it is
also renowned as a city dedicated
to the arts and sciences. This new
role is expressed, with total clarity
and style, by the construction of
a series of public buildings that
exemplify the finest aspects of
contemporary Spanish architecture.
The new tradition of
Spanish architecture
Following in the footsteps of Antonio
Gaudí y Coronet, a name synonymous
with the New Caledonian architectural
school and the founder of modern
Spanish architecture, many present
day Spanish architects have made
their names with innovative, often
daring, and certainly spectacular
design concepts. Foremost amongst
these is Santiago Calatrava Valls
who, with the ‘Museo de las Ciencias’
(Science Museum), has endowed
his home city with a new architectural
treasure.
Calatrava’s masterly use of form
The architecture of Santiago
Calatrava is permeated with
Mediterranean light and colour.
It is also characterised by his
distinctly personal use of form
that ingeniously combines the
dynamic and organic elements
of nature with the solidity and
malleability of building materials
to achieve three-dimensional struc-
tures with an amazing visual impact.
Calatrava’s intuitive application of
materials appears to transform their
physical characteristics. With a
seeming weightlessness; his fine
concrete and metal structures have
the filigree appearance of delicately
structured plants and appear to
contradict their very real function
of supportive structural engineering.
These quite unique design capa-
bilities have been responsible for
Calatrava’s ever increasing inter-
national reputation as an architect,
artist and engineer of supreme
talent. In Spain he has been awarded
the honorary title of ‘Principe de
Asturias’ for the arts.

Valencia - a mecca of architecture and culture
The inspiration of the
Mediterranean landscape
Calatrava’s ‘Museo de las Ciencias’
is part of an arts, culture and leisure
complex, alongside the now dry bed
of the River Turia, all commissioned
by the City of Valencia. In addition
to the museum, there is the Palace
of Arts, a cinema and a planetarium.
The first impression of the museum
is one of a delicately arched space
whose structure admits a flood of
natural light. This impressive,
extensively glazed building runs
parallel to the former riverbed and
the aquatic theme is perpetuated
not only by the repeated concrete
‘wave crests’ but also by a dedi-
cated water feature in the southern
section. The surface of the water
not only projects filtered light into
the vaulted hall of the museum but
also assists the air-conditioning
system by cooling and humidifying
the air flowing into the hall.
The broad footbridge across the
water feature has a dual function
– providing an emergency exit from
the hall and a dramatic ‘stage’ for
diverse activities and events.

Ingenious roof design
With a series of 21 arched saddle
roofs running in parallel, Calatrava
cleverly reduces this immense roof
area to pleasing proportions. At the
same time, performance is at the
forefront with a very functional sys-
tem for the draining of rainwater via
central ‘gutters’ between each rib
of the roof. A total of 21 concrete
spans embrace each section of
Kalzip® roof.
Calatrava’s design specified a built-
up roof system with a smooth inner
skin – this was achieved by the in-
stallation of polyester coated steel
pan ceiling profiles. Each pan was
fitted on-site and supported 60mm
of semi-rigid thermal insulation.
The supporting structure comprised
60mm deep omega profiles mounted
within the pan profiles. These, and
the insulation were then overlaid by
a vapour control barrier. The ST 50
clips, with thermal barrier pads, are
fixed through this sub-structure to
allow the fixing of the Kalzip® outer
sheets. The thermal insulation of
the roof comprises an 80mm layer of
mineral wool compressed to 50mm.
The outer skin of the roof comprises
a total of 11,500 square metres of
Kalzip® 65/333 profiles, 1mm gauge,
stucco embossed finish installed
in sheet lengths of 5.4 metres.
The ridge detail was fixed in the
conventional manner.

Perfect in form and function
At the eaves edge of the roof the
gutters were fabricated to comprise
a total of 6.9 metres of extruded
aluminium L-shaped profiles per
section. The inner end plates are
fabricated from the same stucco
embossed material as the outer
Kalzip® sheet.
The gutters themselves are made
from 1.2mm gauge stucco em-
bossed clad alloy aluminium to
form a single shell with a width
of 750mm. The separate lengths
were welded by on-site specialists.
Thermal expansion is accommo-
dated by the insertion of expansion
joints.
The convex ridges of the roof
structure are clad in aluminium
flashings colour coated in white
to complement the concrete
structure.

The cladding of the rising bays of
the museum is the same as that
used for the roof to give an overall
integrity of design and appearance,
interspersed by the same lateral
concrete arches.
Reflecting a diffuse light, the
Kalzip® sheets form the perfect
complement to the large glazed
areas, light concrete spans and
water features – all reacting to the
dramatic effects of Mediterranean
sun and light.
In summary
Calatrava’s ‘Museum de las Ciencias’
is yet another demonstration of the
opportunity that Kalzip® extends to
modern architects – freeing creativity
whilst guaranteeing performance in
terms of both form and function.
