An adaptive reuse of a former historic power plant, the Energy Partners Innovation Center (EPIcenter) represents San Antonio’s new think tank that unites entrepreneurs, technologists and communities to foster creative ideas for a brighter energy future. The iconic 4-level destination thoughtfully integrates differently scaled spaces, emphasizing transparency to lighten the heaviness of the plant. A clear sequence exists for public consumption, with controlled circulation at the private, upper-level offices. The grand lobby and café have visual presence on either side, while overlooks help balance interaction between public and private realms. EPIcenter also features exhibition space, collaborative workspaces, a resource center featuring a fabrication lab, and a dynamic outdoor venue for large gatherings. Mechanical systems and sustainability measures are on display as learning tools.
