COMPUTATIONAL FLUID DYNAMICS MODELING

We are able to apply our extensive Computational Fluid Dynamics (CFD) modeling capabilities to understand the dynamics of heat transfer, airflow and dispersion for many different applications.

  • Evaluate impact of temporary cooling outages and benefits of thermal ride-through
  • Determine cooling effectiveness throughout data center and identify potential for hot-spots
  • Proactively understand IT deployments including high-density loads (15kW to 40kW per rack)
  • Potential for capacity reductions of generators, drycoolers, chillers due to micro-climates
  • Compare design alternatives such as hot / cold aisle containment, raised floor grille types
  • Simulate different operating conditions to understand energy savings potential


ENERGY CONSERVATION MEASURES / SAVINGS

We have successfully achieved significant energy savings in existing data centers of all sizes. Below are some of the energy conservation measures that generally have a payback of less than 2-3 years.

LOW COST ENERGY CONSERVATION MEASURES
  • Modify Cooling Plant Strategy and Sequence
  • Floor Tile Balancing, Seal Penetrations
  • Implement Server Power Management
  • Optimize Chilled Water Temperature
  • Optimize Supply Air Temperature
AVERAGE COST ENERGY CONSERVATION MEASURES
  • CRAC Unit VFDs and Improved Control Sequences
  • Install Monitoring and Measurement Systems
  • Widen the tolerance for humidity control
  • Install Containment / Blanking Panels


OPERATIONS SUPPORT EXAMPLES
  • Cooling System – Upgrades and resiliency improvements
  • Diagnostics – Rack-mounted transfer switch failure root cause analysis
  • Mechanical Infrastructure Analysis – Pipe flow analysis, pipe stress analysis, and controls investigation
  • Re-Commissioning – Electrical infrastructure including Medium Voltage transformers, Automatic Transfer Switches, cables, generators and busway
  • Electrical Infrastructure Analysis – Single-line verification, arc flash and coordination study, duct bank feeder capacity analysis, bus duct evaluation


OPERATIONS SUPPORT
AUDIT & EVALUATION

Performance and reliability of a data center is heavily reliant on the Operations team. A well designed and constructed facility can fail if it lacks a properly staffed, trained and equipped team to operate & maintain it.

  • A major wireless network provider requested an audit and evaluation of its current mission-critical facility operations at three locations to better understand how its operations compared to those of its peers in the industry.
  • Based on agreed upon criteria, we identified deficiencies and prepared recommendations to increase reliability, and reduce operational expenses.
  • Our scope included a thorough review of Operational & Emergency procedures and critical documentation.


DATA CENTER COMMISSIONING

Commissioning is a quality-oriented process for achieving, verifying, and documenting that the performance of facilities, systems, and assemblies meets defined objectives and criteria.

DLB provides commissioning services for all industries, including data centers. Some clients we have provided data center commissioning services for include:

  • Rackspace
  • Level 3
  • Google
  • NY Mass Transit Authority (MTA)
  • Verizon Wireless
  • Morgan Stanley
  • Internap


AUTOMATION IN DATA CENTERS

Our intimate knowledge of data center design and operation provides a deep understanding of mechanical and electrical system complexity.

Coupled with our experience in the commercial and industrial automation industries, we are able to identify the right solutions using the right products to meet the many unique performance and reliability requirements of a data center.

Selecting the proper hardware, software, instrumentation are crucial steps for a data center Building Management Systems (BMS) and are rarely given enough attention.

Furthermore, a controls system is only as good as how it is operated and without the proper emphasis on training and documentation, BMS will often be underutilized.

Ultimately, evaluating various commercial and industrial options against the Owner's Program Requirements (OPR) for all aspects of the BMS, and doing so while looking beyond first costs, will deliver the best total solution.
