chilean architects eugenio simonetti t + renato stewart l. have created 'costanera lyon 1', a prototypical office
tower in santiago, chile. the unified structure of this pair of office buildings combines vierendeel beams
and scissor columns to produce seismic resistant towers. a single mass exterior creates a thermal mass which is
easy to heat and cool without a double skin to reduce energy consumption. currently complete, the first prototype
features a portion of the corner which has been removed and placed upon the roof, creating a penthouse floor and pool.
the void is visible from the dynamic street and creates a different identity from the second prototype.

the second iteration features cantilevered slabs to utilize the site area, but required additional support to resist the
lateral forces of the earthquake prone region. perimetral walls contribute to torsional rigidity while 21 vierendeel beams
carry the building's dead weight and open the interior for unobstructed outward views. fourteen scissor base columns
support the 16 slabs service placed around one core. conceived as a wholistic entity, each element is necessary to retain
its stability and without one piece, the structure would not stand.
