Flexential Portland - Hillsboro 4

Flexential's Hillsboro 4 building sits at 4915 NE Starr Boulevard in Hillsboro, Oregon, part of a cluster of Flexential-owned buildings in the Portland metro's Silicon Forest that now runs to six named facilities. The site totals roughly 138,000 sq ft and is designed for 18 MW of distributed-redundant critical power with N+2 cooling and a 1.4 target power usage effectiveness, using hot-aisle containment. Flexential markets the building's cooling system as a zero-water-use (WUE = 0) design, a point of emphasis in a region where several hyperscale data center buildouts have drawn scrutiny over municipal water use. As with most of Flexential's older facility pages, the operator does not publish a year-opened date, tenant list, or third-party Uptime Institute or TIA-942 certification for this specific building — its compliance claims (SOC, PCI DSS, ISO-family frameworks) are stated at the company level rather than audited per site in the source material available. Hillsboro 4 predates the operator's newer, larger Hillsboro 5 and Hillsboro 6 buildings, which were announced later as part of Flexential's continued expansion in the same submarket.
