The Mercantile worked with The Salcido Connection to transform a sprawling, outdated retail building in downtown Wenatchee into an inviting blend of open workspaces, private office suites, conference rooms and a comfy-couch lounge. Chelan PUD rebates helped pay for the energy-efficient lighting, lighting controls, windows and web-enabled thermostats at the historic Mercantile, 14 N. Wenatchee Ave.
