- The Importance of Computational Fluid Dynamics for Data Center Equipment Yard Layout Design
As the demand for more data center space, power, and cooling continues to increase, the need for space management and equipment layout has become a critical design requirement. The increased load densities in the data center white space has led to an increased amount of support equipment, both inside and outside the data center building. Inside the building The mechanical cooling equipment such as the Computer Room Air Handling (CRAH) units, share space with electrical power equipment like the Power Distribution Unit (PDU) units in the CRAH gallery. They share space for several reasons which include but are not limited to PDU heat rejection contained in the gallery. The heat from the PDU is immediately rejected in the CRAH unit cooling system and this layout does not require a separate electrical room for the PDUs. Figure 1 below is a typical data center layout with CRAH units and PDUs sharing space in the CRAH Gallery. Figure 1 Typical data center layout with hot aisle containment and CRAH galleries on the opposite side of the data center Outside the building Either in the yard, on the roof, or both, mechanical heat rejection systems such as cooling towers and chillers share space with electrical standby generators. A compact high-density layout inside the building results in a compact outdoor equipment layout. This leads to significant airflow management challenges and issues outside of the building. Airflow patterns outside of the building are difficult to predict because of the different variables which design engineers and architects are not able to control. These variables include wind speed, air temperature and humidity, wind direction, and other activities surrounding the building. All these would impact the performance of the outdoor data center equipment. The Computational Fluid Dynamics (CFD) analysis has become a critical tool for data center design for optimum yard or roof equipment layout. There are several CFD software vendors available on the market that are used for analysis and simulations. These simulations provide results that help data center owners and designers in the decision-making process in determining cost-effective layouts and performance. The CFD analysis when performed before the design is finalized and implemented helps in mitigating risks associated with design errors at the late stages of the design, which would result in significant and expensive change orders, construction delays or loss of compute capacity. Most manufacturer’s equipment literature provides yard and roof equipment minimum placement clearance requirements. While this information is provided as guidelines, it is expected that designers will make a correct judgment when finalizing design layouts. A good example of this is a chiller manufacturer’s recommended minimum of 8-foot clearance from solid obstruction. However, these guidelines do not factor in ambient air conditions, wind speed, or height of the obstruction. Figure 2 below demonstrates how following a manufacturer’s recommended minimum clearance can result in undesired air-cooled chiller performance due to air recirculation. Figure 2 Air Cooled Chiller Recirculation Demonstration With the use of CFD analysis and simulation, the condition demonstrated on Figure 2 is identified and corrected before the design is finalized and construction is completed. Another way the CFD analysis and simulation is a useful tool is by providing and understanding how multiple airflow patterns will interact with each other. Figure 3 below demonstrates the impact of generator exhaust air on the mechanical heat rejection equipment on the roof. In Figure 3 the hot exhaust air from the generator flue pipe and the radiator blown towards the building causes a stagnant air condition by the building. As a result of this condition the mechanical equipment inlet ambient air temperature range is outside of recommended manufacturer’s range which causes equipment not to perform as specified. Figure 3 Generator Exhaust Air impact on Mechanical Equipment on the Roof Conclusion In conclusion, the Computational Fluid Dynamic analysis and simulation tools available in the market, have become a critical tool in design for new and existing data centers. CFD analysis is one of EYP Mission Critical Facilities’ most important and powerful tools used at every stage of the project to vet and verify that solutions proposed in our design will yield expected performance results. The expected performance results are subject to varying climatic and weather conditions at the data center location as typically published by DOE, NOAA, and ASHRAE.

- EYP MCF, and i3 Solutions Group Announce Collaboration to Tackle Data Center Sustainability
- Leading global consulting engineers combine resources to drive thought leadership for data center GHG abatement. - Offer a practical roadmap towards a Carbon Net-Zero data center by 2030. - Highlight near-term opportunities for clean embedded primary and backup power generation and grid demand support. January 27th, 2021, New York, London & Singapore: Leading consulting engineering firms EYP Mission Critical Facilities, Inc. (EYPMCF) and i3 Solutions Group have announced a collaboration to offer a response to the climate crisis through Green House Gas (GHG) reduction initiatives for the data center sector, including a practical roadmap of progressive GHG abatement for existing data centers and net-zero GHG data centers by 2030. “As a major consumer of electricity and therefore a contributor to global emissions, the data center sector faces the prospect of regulation to reduce its impact on the planet,” said Rick Einhorn, Co-Founder and Co-Managing Partner at EYPMCF. “I’m pleased to announce this initiative by EYPMCF and i3 Solutions Group which brings together a respected team of data center MEP design engineers and operational consultants to offer thought leadership in data center emissions and carbon reduction, efficiency and sustainability.” Ed Ansett, Founder and Chairman of i3 Solutions Group said, “While the future of data center sustainability undoubtedly has a 100% renewable face, we are a long way from that end point. However, there are opportunities for large data center operators in hyperscale, wholesale, colocation and other sectors to engage in GHG abatement. This requires a paradigm shift, but the good news is, we can evolve from a GHG intensive, inefficient infrastructure to a reduced or even net-zero GHG asset with new revenue generating opportunities. For that to happen requires the inspiration of specialist data center design and strategy.” Those designing, building and operating data centers need to assimilate the technical considerations across a range of on-site power generation and energy storage solutions that practically address GHG abatement, evolving regulatory requirements and end-user performance requirements, at the same time taking full advantage of renewable energy sources and sustainable technologies. Accordingly, the collaboration between EYPMCF and i3 is developing objective material covering the following subjects: • A practical roadmap toward GHG abatement and carbon net-zero data centers by 2030 • Low GHG energy trading opportunities for large scale data centers • Demand side frequency and sag response, primary operation, and operating reserve opportunities for data center embedded generation and storage systems • GHG reduction with blended hydrogen and natural gas generation for data centers • Reliability implications of primary and standby embedded generation and energy storage systems for data centers

For an investor, data center due diligence in the colocation and service provider sector requires more than just reviewing power and cooling infrastructure. Critical facilities due diligence efforts and opinions typically include reviews and assessments of existing asset conditions, one-line diagrams, equipment age, building management systems, Capex/Opex, Tier levels/equivalents, energy efficiency, and potential points of failure. "It is critical to understand the applications, security and processes in place for both the acquirer and the target." At EYP Mission Critical Facilities (EYP MCF), we often provide ROM cost estimates for expansion, upgrades or improvements identified in the course of our analysis. On top of this, our due diligence service offering can include additional areas beyond the mere physical asset assessment an engineering firm would provide that need to be well-understood as part of any merger or acquisition. These areas include: Operational procedures, maintenance management and staffing. These elements both drive costs and are frequently important elements in data center outages. Review of commissioning reports and historical failure incident report logs. Identifying reasoning for past failures that typically are a result of human error or in some cases may identify a more serious issue with building infrastructure. IT systems architecture. It is critical to understand the applications, security and processes in place for both the acquirer and the target. These elements are key revenue drivers (and important to SLAs of course) and the expected synergies, integration costs for multiple systems, and risks to the overall data center must be understood. Understanding these critical aspects of a deal during the due diligence phase is often overlooked and should be included in this process. A systems architecture assessment is important due to the tight integration and effect that it can have on the operations, management, and client (whether external or internal) facing environment. "A due diligence effort should include additional areas beyond the mere physical asset typically reviewed" DCD News Blog The enterprise and operations back end has serious impact on the underlying effectiveness of services and TCO. Choices of Operations Management suites, monitoring tools, client portals, use of Cloud, SaaS/PaaS, all have definitive impacts on Capex/Opex and the reliability and resiliency of the facility asset. This integration goes to the value of the purchase or more importantly uncovers the potential future state investments you may need make. Without this type of additional analysis, the acquirer may not have as accurate an understanding of the value of an asset as they should, to make informed decisions. As pointed on the DCD News Blog, "A due diligence effort should include additional areas beyond the mere physical asset typically reviewed" If you are a data center investor or holding company, please let us know how we can assist you with your growth and acquisition strategy.
