H5 Data Centers Plans Screen Wall on Saint Clair After Acquiring Adjacent Buildings for Generator Expansion

H5 Data Centers filed a construction permit on April 6, 2026 to demolish adjacent commercial buildings along Emerald Court and construct a new screen wall along Saint Clair Avenue at its Cleveland Technology Center campus, 1625 Rockwell Avenue.

The $250,000 project, designed by Dale Grieder of The Foundation Architecture LLC, is the latest phase in H5's ongoing expansion of its Cleveland data center. The company acquired the Cleveland Technology Center — a 333,000-square-foot Tier III colocation facility — from ByteGrid in 2017 for $30 million. The campus hosts more than 23 network providers, the CL-IX Cleveland Internet Exchange, and serves enterprise, healthcare, and biotech tenants.

H5 has steadily grown its Cleveland footprint. In 2018, the company announced a 25,000-square-foot buildout pre-leased by a Fortune 500 client. In 2022, H5 filed with the Cleveland City Planning Commission to add a generator building on the site's parking lot and renovate the East 13th Street facade, working at the time with Arkinetics and PTA Engineering.

This new permit represents a further expansion of the facility's power infrastructure. H5 has acquired buildings along Emerald Court — a small side street between Rockwell Avenue and Saint Clair Avenue — and plans to demolish them to enlarge the generator yard. To preserve the streetscape, the company proposes a screen wall along Saint Clair Avenue that will maintain the architectural characteristics of the demolished storefronts.

The project is located in Ward 8, in Cleveland's St. Clair-Superior neighborhood. The permit is currently in review with the city's building department.
