Equinix SE3 is an 8-story, steel-frame concrete building at 2020 Fifth Ave in downtown Seattle, adjacent to the Westin Building that houses sister facility SE2. Equinix opened SE3 as its second Seattle-metro IBX on March 14, 2013, with roughly 51,000 sq ft of data center space and capacity for more than 1,000 cabinet equivalents at the time, per the operator's opening announcement; the current facility page lists a smaller 36,457 sq ft (3,387 sqm) of colocation space, reflecting the site's present configuration rather than the original build-out. Published specs show distributed-redundant N+1 UPS, N+1 cooling redundancy via water-cooled DX rooftop units with air-side economizers, and a minimum cabinet density of 4 kVA on 120V/208V distribution. The building's first phase is LEED Gold certified, alongside Energy Star recognition in multiple years. Certifications named on the facility page are HECVAT, HIPAA, ISO 22301, ISO 27001, ISO 50001, ISO 9001, LEED, NIST 800-53/FISMA High, PCI DSS, SOC 1 Type II and SOC 2 Type II.
