IMEG provided engineering design services for a 78,000-sf renovation of a seven-story office building into Police Headquarters for the City of Clayton. In addition to the police department, the building houses the Information Systems department, additional city offices, and two federal tenants.

Challenges included:

• Low floor-to-floor heights with limited plenum space for mechanical and electrical systems
• Ensuring critical operations power system requirements are met
• Urban setting restricts accessibility with limited site options
• Electrical utility service modification requirements on a limited site

The project was funded in part through two energy grants distributed from the American Recovery and Reinvestment Act (ARRA) for a 100 KW photovoltaic array in the attached parking garage, increasing the energy efficiency of the mechanical and lighting systems.

The project included a 500-sf data center to serve as the city’s main data center. The data center space shares the building emergency generator, and included modular UPS racks with hot swappable batteries for the backup power. The data center also included an enclosed hot isle containment system and in-row cooling units with no raised floor.
