Low energy use was a particular priority for the Triskelion, a 1,300-square-foot moveable pavilion commissioned by the nonprofit arts organization FOR-SITE. Designed by Ogrydziak/Prillinger Architects, San Francisco, the building consists of three shipping containers arranged at 120-degree angles to define a central skylit atrium. Since May 2010 it has been installed at the Presidio, where it was part of the yearlong Presidio Habitats'an exhibition of artist-created animal habitats distributed around one corner of the national park. The pavilion served as a space for the display of sketches and models.
Because Presidio officials required that the building be easily demountable and leave no trace of its existence once removed, the Triskelion could not tie into nearby utilities. It needed to be completely 'untethered' from the site, says architect Luke Ogrydziak.
