in one venue. It also hosts major international
concerts, shows and festivals with the
dramatic skyline of the city of Singapore as a
backdrop.

An engineering feat
The National Stadium roof, at 310 meters,
is the world’s largest free-span dome. The
moveable roof provides shade and cooling
when required and of course shelter from
rainfall. The roof is left open when the
Stadium is not in use, keeping the grass pitch
in healthy condition. The moveable section of
the roof incorporates a matrix of LED lighting
and, at 20,000 square meters it is one of the
largest LED displays in the world.

Comfort in the tropics
The National Stadium is a model for tropical
climate design. It features an innovative
energy-efficient spectator cooling system
that delivers cooled air to every seat in the
stadium. These pockets of cooled air will
reduce energy use significantly, compared
to a more conventional overhead cooling
system. The ultra-thin dome roof structure
with a movable roof that extends over the
pitch provides shade during events.

Total architecture
Arup has a long-standing track record
of bringing the best of its international Elite-level sports functionality as well as every-day use are both key drivers for the
expertise to large projects around the new National Stadium design

A radical cooling system ensures that the stadium will be comfortable whatever the occasion or sporting event. Instead of being supplied at
a high level, cooled air will be introduced beneath stadium seats. This will also minimise the volume of air cooled and thus considerably cut
energy use. Giant louvres, meanwhile, will provide protection from sun and rain for the grand arcade encircling the stadium, and allow a free
circulation of air
