Fifth Third Bank Museum

Converting an active bank branch into a museum calls for more than a change in floor plan. At Fifth Third Bank’s downtown Cincinnati headquarters, the transformation created a new home for the institution’s history, bringing together hundreds of artifacts, some more than a century old, with interactive exhibits designed to engage visitors.

Motz Engineering provided mechanical, electrical, and plumbing engineering for the 12,000-square-foot museum. The project required building systems that could serve two distinct priorities: maintaining suitable environmental conditions for historic collections and supporting the audiovisual technology at the heart of the visitor experience.

To help protect the collection, Motz designed a stand-alone HVAC system with dedicated thermostat controls for precise temperature and humidity management. Unlike a conventional office or branch environment, a museum housing aging documents, equipment, and other artifacts must consider how fluctuations in indoor conditions can affect the materials on display.

The exhibit technology introduced a different set of engineering requirements. Four interactive audiovisual walls needed reliable, clean electrical service to deliver clear displays. Motz specified a separate, isolated transformer for the video and audio equipment to reduce electrical interference that could otherwise appear as visual noise or scrolling bars on the screens. The team also developed conduit and wiring specifications for the data and IT devices supporting the exhibits.

Together, these solutions helped adapt an existing commercial space for a specialized use without losing sight of its dual purpose: preserving the bank’s history and making that history accessible through modern technology.

For owners converting existing spaces into museums, galleries, or other collection-based environments, early MEP planning is essential. Environmental controls and technology infrastructure should be evaluated alongside exhibit design so that preservation requirements, display performance, and future maintenance needs are addressed before construction.

The Fifth Third Bank Headquarters Museum illustrates how targeted mechanical and electrical design can support both the long-term care of historic artifacts and an engaging, technology-rich visitor experience.
