CONTROL YOUR DATA CENTER!

1. CONTROL YOUR DATA CENTER! Tune your Legacy Data Center to improve overall efficiencies

2. TYPICAL LEGACY DATA CENTER ISSUES • ISSUES THAT DEVELOP OVER TIME IN DATA CENTERS • Mismatched IT System availability expectations and inadequate facilities cooling capabilities to support these expectations • Mismatched power and cooling infrastructure leading to an increase in operating costs and poor capital investment strategies • Lack of airflow control (issues with bypass and leakage) • No Master Plan for Computer Facilities • Increased heat densities • Inefficient use of computer equipment

3. RETRO-COMMISSION AND RE-COMMISSION • RETRO-COMMISSIONING • Retro-commissioning is an event in the life of a building that applies a systematic investigation process for improving and optimizing a building’s Operation and Maintenance occurring after construction completed and the building is occupied, as an independent process, with a focus usually on energy-consuming equipment and systems such as HVAC, mechanical equipment, lighting, and control systems

4. RETRO-COMMISSION AND RE-COMMISSION (con’t) • RE-COMMISSIONING • Re-commissioning uses the original commissioning scripts, modified as required, to test existing building equipment and systems during the life of the building • Re-commissioning is recommended whenever major equipment or systems are modified in a major manner, upgraded, or replaced

5. DATA CENTER LIFE Infant Mortality Period End-of- Life Period Original commissioning Maximize Failures Minimize Minimize Time Retro-commissioning and Re-commissioning efforts

6. THE TUNING PROCESS • STRATEGIES TO SUPPORT RETRO-COMMISSIONING • Develop a set of objectives for upgrading the current Data Center • Using those objectives • Develop a Data Center information sheet • Develop a checklist of property documentation for the Data Center • Create a benchmark of energy use for the Data Center • Investigate outside available resources that could offset costs

7. CONTINUING THE TUNING PROCESS - • MORE OF THE STRATEGY • Obtain buy-in from those who need to approve the implementation budget • Retain the Commissioning group to perform the Retro-commissioning • Provide the package of building documentation, benchmarking results, other checklists, findings, and resolutions to the Cx provider • Perform simple repairs as the project progresses • Develop scopes of work for implementing “fixes” and improvements that cannot be performed in-house • Verify the improvements were implemented

8. CONTINUING THE TUNING PROCESS - • BEYOND RETROCOMMISSIONING • Perform on-going utility bill analysis and periodic re-benchmarking in order to identify unjustified increases in energy • Develop a plan to monitor important control points in the mechanical and electrical infrastructure • Keep staff informed of energy use levels, Data Center changes planned

9. CONTINUING THE TUNING PROCESS - • CONTINUING BEYOND RETRO-COMMISSIONING • Keep record documents current • Record systems modifications on drawings • Update maintenance procedures and schedules as necessary • Update the Owner’s Project Requirements and Basis of Design as necessary • Update changes in walls, systems, and assemblies • Track HVAC readings and operations data so that repairs and replacement strategies can be developed • Perform Re-commissioning of HVAC systems as required

10. A HEALTHY LEGACY DATA CENTER • VIGILENCE IS THE KEY TO SUCCESS • Communication • Discussion • Decision • Action
