1. Integrating a Data Center into an Engineering Laboratory Building
Presented by:
Sean T. Convery, P.E.
Principal
Cator, Ruma & Associates, Co.
Colorado State University – Suzanne and Walter Scott, Jr. Bioengineering Building

2. Learning Objectives
How to position the data center in a laboratory building to optimize hot air recovery for the rest of the building while minimizing first cost.
System design to utilize chilled water twice for maximizing delta-T.

3. Introduction
120,000-square-foot (sq. ft.) facility.
Housing high tech engineering laboratories consisting of wet labs and electronic labs, offices, and classrooms.
A 2000 sq. ft. Data Center is included.
The Data Center will be a hybrid of low density racks consolidated from other parts of campus mixed with high density racks to be installed in the future.

4. Position Data Center to Optimize Hot Air Recovery

5. Low Density vs. High Density Racks
Air-Cooled vs. Water Cooled
Limitations of Airside System

11. Phase 1 – Air Cooled Racks (1) 38,000 cfm ahu

12. Future Phase – Air Cooled Racks (2) 38,000 cfm ahu’s

13. Using Chilled Water Twice
“Adjusting the delta-T’s up will have a significant impact on both freed capacity, improved system efficiency and reduced chiller maintenance associated with a reduced run time.”
- Quote from CSU District Cooling Plant Supervisor

15. Lessons learned
Don’t VE out a heating coil!  Understand when all servers will be installed!

16. Lessons learned
Hot Aisle Containment Methods – New vs. Used Rack Systems
