Responsibilities: Data Center Heat Rejection and HVAC System Design: Developing and designing Heat Rejection and HVAC systems tailored for data centers, considering cooling requirements, future flexibility, phased construction, airflow management, humidity control, system redundancy, energy efficiency, and compliance with industry standards. Cooling System Selection: Selecting appropriate air/water side cooling systems such as Fan wall units, computer room air handlers (CRAHs), chilled water systems, DX systems, CRAC units, in‑row cooling, and containment solutions based on specific cooling requirements and equipment criticality. Computational Fluid Dynamics (CFD) Analysis: Conducting internal CFD simulations to optimize airflow distribution, identify hotspots, and ensure efficient cooling. Conducting external CFD on individual buildings or campus‑wide to evaluate interactions of electrical and mechanical components, preparing models, analyzing results, recommending design modifications, and coordinating changes with other trades. Redundancy and Fault Tolerance: Designing HVAC systems with redundancy and fault‑tolerant features to maintain continuous operation during equipment failure or maintenance, including backup cooling, automatic switchover mechanisms, and monitoring systems. Heat Load Calculation and Capacity Planning: Performing heat load calculations for IT equipment, power density, anticipated growth, and phasing to determine cooling requirements; conducting capacity planning to accommodate future expansions and upgrades; performing HVAC loads for administrative and common areas. Energy Efficiency and Sustainability: Implementing energy‑efficient design strategies such as economizers, variable speed drives, energy recovery, and airflow management to minimize consumption and support sustainability initiatives. Air Quality and Filtration: Designing filtration systems and monitoring mechanisms to maintain optimal air quality, address particulate matter, humidity, and contaminant removal, protecting sensitive IT equipment. Coordination with Electrical and Mechanical Systems: Collaborating with electrical and mechanical engineers to integrate heat rejection and HVAC with electrical infrastructure, UPS, emergency power, fire suppression, and other critical infrastructure components. Minimum Qualifications: Bachelor's Degree with 6+ years of relevant experience or equivalent education and experience. Experience in data center mechanical and electrical equipment installation and operation. Professional Engineer (P. E.) registration required. Preferred Qualifications: Bachelor's degree in Mechanical Engineering, HVAC Engineering, or a related field; master's degree or advanced coursework in HVAC systems or energy management preferred. Knowledge of data center TER Standard Topology per Uptime Institute, TIA 942, ANSI/BICSI 002. Professional certifications such as Certified Energy Manager (CEM), Building Energy Modeling Professional (BEMP), or LEED accreditation advantageous.
