Dayton Children's Hospital
Data Center
Project Overview
HEAPY designed the mechanical, electrical, plumbing and technology systems for the expansion of Dayton Children’s Hospital, which included a new, eight-story, 260,000 SF patient tower, new central utility plant, and new data center. The following systems were included in the design of the data center:
Electrical:
- New 100% LED energy efficient lighting with automatic controls for optimal energy usage.
- Two (2) new 1,500kW generators and associated paralleling gear for emergency backup of the data center and hospital emergency power.
- Distribution and equipment layouts for the entire facility, coordination of UPS’s, transfer equipment, and power associated with the HVAC system for optimal system diversification and redundancy.
- Complete redundant power was provided to meet the hospitals data system requirements with a
tier 3 installation. - Bus duct in the data room to provide flexibility in adding loads without disruption.
- Metering on all data center equipment to allow for smart decision making for new loads.
Mechanical:
- HVAC system included redundant CRAC units to meet the requires of a Tier 3 installation. CRAC
units in the white space feature a refrigerant economizer. CRAC fans are variable speed. Hot air return from data racks is ducted using a passive chimney to air return plenum. Computational fluid dynamics (CFD) modeling aided final configuration of data hall cooling system. - The remaining data center space is heated and cooled by a heat recovery air cooled VRF system.
- Building pressurization and ventilation is provided by a dedicated outdoor air system (DOAS)
featuring energy recovery.
Fire Alarm and Fire Suppression:
- A special microprocessor based double supervised, closed circuit system.
- A complete Vesda early warning smoke detection system has been provided for the total space with special detection for the data racks and CRAC units.
- The building is designed around a Wet system, featuring a double interlocking pre-action system in the data center, PBX room, and UPS room, with a nitrogen generator compressed air dry system.
