SUMAC provided commissioning services for the Viceroy Hotel in Chicago, verifying that the building's systems were designed, installed, and commissioned in accordance with the performance, efficiency, and comfort criteria established for the project.

The hotel, located in the Gold Coast neighborhood, combines the preservation of the historic facade of the former Cedar Hotel with a new contemporary 18-story tower with 180 rooms. This integration of heritage and contemporary design creates an architectural proposal that balances historical identity and modernity.
