Construction: The operating site is one building at 1500 Champa Street. IPI announced its acquisition and investment in December 2021, initially projecting construction completion by Q4 2022. RadiusDC later reported that two data halls were completed and commissioned, with 3 MW available in 2023. An additional expansion was reported under construction in February 2024; a contractor lists a Phase 3–4 expansion-renovation project running August 2024–May 2025. Later RadiusDC material described roughly 15,000 SF and up to 2 MW as future expansion, and in August 2026 said it was evaluating expansion opportunities; no online date or commissioning of that additional capacity is confirmed. Capacity figures are not additive: DataBank lists DEN3 at 2 MW critical IT load, while RadiusDC describes up to 3 MW across its two in-service halls. IPI’s 2021 release described approximately 10 MW as the facility’s potential, not as operating capacity.

Initial two-hall build-out

The initial two-hall build-out was announced with an original Q4 2022 construction-completion projection. RadiusDC later reported both halls completed and commissioned and 3 MW available in 2023. The halls are each approximately 6,750 SF; RadiusDC’s earlier brochure described approximately 16,000 SF of data-center space across the two halls.

Incremental expansion / Phase 3–4 renovations

RadiusDC described approximately 18,000 SF supporting up to 2 MW as under construction in February 2024. Its April 2025 brochure described up to approximately 15,000 SF and 2 MW as future expansion. A contractor lists a Phase 3–4 expansion-renovation project duration of August 2024–May 2025. RadiusDC’s August 2026 market page says it is evaluating expansion opportunities. The contractor’s project duration does not establish that this capacity was commissioned or online.

Cooling medium

Chilled water, according to a third-party profile for DEN3.

Fiber and connectivity

DEN3 sits at the intersection of major fiber pathways serving Denver and the Rocky Mountain region. A fiber vault between the facility and the nearby Denver Gas and Electric Building provides access to hundreds of ISPs and carriers.

Operating context

Carrier-hotel colocation facility offering colocation cabinets, managed internet connectivity, in-region DataBank Cloud, and HPC compatibility. DataBank lists 2 MW of critical IT load, N+1 power and cooling, and a 100% uptime SLA.

Environmental commitments

DataBank's company-wide commitment is to achieve net-zero Scope 1 and 2 emissions by 2030; a separate DEN3-specific target is not stated.

Environmental impacts

DEN3 is reported to have diesel backup generators, a potential direct combustion-emissions source when used; no site-specific emissions quantity is stated.

Permits and dockets

Denver Bill 26-0431, passed May 20, 2026: authorizes a one-year moratorium on certain zoning-permit and site-development applications for establishing or expanding a primary-use data center. The cited record does not identify a DEN3-specific permit.

Transactions

The 1500 Champa building was acquired by an IPI affiliate from Morgan Reed Group in 2021; Deutsche Bank Credit Solutions and Direct Lending financed the acquisition. A third-party property-sale record lists a December 9, 2021 sale price of $92 million, while IPI's acquisition announcement says financial terms were not disclosed, so the reported price is not confirmed by the announcement. · Radius DC's phases 3–4 renovation and data-center expansion at 1500 Champa ran from August 2024 to May 2025; the project included electrical, mechanical, security, and associated finishes. No project cost is stated.

Public hearings

On May 18, 2026, Denver City Council considered citywide bill 26-0431 at a public hearing and advanced the moratorium. This was not a hearing about DEN3 or 1500 Champa; the measure concerns new data centers and expansions, so it is regulatory context for any future expansion rather than evidence of a site-specific proceeding.

Community benefits

RadiusDC announced a planned façade improvement at 1500 Champa, describing it as a contribution to downtown revitalization and a way to improve the building’s appearance and promote community pride. The Downtown Denver Partnership’s president endorsed the project as beautifying the urban landscape and representing investment in the city center. These are stated aims and endorsements; the sources do not establish that the work was completed or measure its effects.
