| This was the
Utopia pavilion during the EXPO’98,
and is a multipurpose arena for 17,000 spectators, which has all the necessary services
for a modern multifunctional infrastructure. It will house sporting events, congresses,
exhibitions and other activities, with a TV room, press room, medical quarters and a
restaurant, and represents an urban anchor and an essential feature for the Lisbon area. It will have high standards of comfort using
intelligent management technology, with a choice in the use of types of energy available,
in an outstanding architectural example of energy efficiency and respect for the
environment.
