Our designs account for future density increases, allowing facilities to scale from air cooling to liquid cooling as workload requirements evolve without wholesale infrastructure replacement.
We've successfully deployed cooling systems across this entire density spectrum, from traditional enterprise datacenters to hyperscale AI training facilities. Our engineering team conducts comprehensive computational fluid dynamics (CFD) modeling and thermal analysis ensuring optimal performance for your specific hardware configuration and density requirements.
Timeline depends heavily on project complexity, site conditions, and delivery method, but typical ranges are 18-30 months from design initiation to full commissioning for a 50-100MW facility. Here's a breakdown:
Planning & Design (4-6 months): Conceptual design, utility coordination, permitting preparation, and detailed mechanical/electrical design packages. This phase includes equipment specifications, control narratives, and construction documentation.
Permitting & Procurement (3-6 months, parallel): Building permits, environmental approvals, utility interconnection agreements, and long-lead equipment procurement. Chillers, cooling towers, and major mechanical equipment often have 6-9 month lead times, making early procurement critical.
Construction (10-14 months): Site work, building shell, mechanical/electrical installation, and controls integration. Modular approaches using prefabricated equipment skids can reduce this phase by 30-40%, bringing timelines down to 7-10 months.
Commissioning & Startup (2-3 months): Functional performance testing, control sequence verification, integrated system testing, and operator training. This ensures all systems meet design specifications before tenant occupancy.
Phased approaches can accelerate time-to-revenue by bringing initial capacity online in 12-15 months while subsequent phases complete construction. Our prefabricated solutions and modular designs are specifically engineered to minimize deployment timelines while maintaining quality and performance standards. For existing facility retrofits or adaptive reuse projects, timelines may be shorter (12-18 months) since building shell and some infrastructure already exist.
Achieving world-class energy efficiency (PUE below 1.2) for AI datacenter infrastructure requires integrated optimization across multiple mechanical system components:
Free Cooling Integration: Our designs maximize hours operating in free cooling mode by leveraging favorable outdoor conditions. Water-side economizers using cooling towers or adiabatic dry coolers provide "free" cooling when outdoor wet bulb temperatures permit. In optimal climates, facilities can achieve 4,000-6,000+ annual free cooling hours, dramatically reducing mechanical cooling energy.
High-Efficiency Equipment: We specify premium efficiency chillers with magnetic bearing compressors, variable speed drives on all rotating equipment (chillers, pumps, cooling tower fans), and optimized heat exchangers minimizing pressure drops. These selections reduce mechanical system energy consumption by 20-30% versus standard efficiency equipment.
Advanced Control Sequences: Our building management systems continuously optimize equipment operation based on real-time loads, outdoor conditions, and utility rates. Chiller staging algorithms minimize total plant energy. Supply water temperature reset strategies reduce pumping and cooling tower energy. Demand-based controls adjust equipment speed and capacity to actual thermal loads rather than running at fixed speeds.
Liquid Cooling Benefits: Direct-to-chip liquid cooling enables higher supply water temperatures (up to 95-105°F versus 45-55°F for air cooling), dramatically improving chiller efficiency and expanding free cooling hours. Eliminating CRAH fans and reducing airflow requirements further reduces facility energy consumption.
Right-Sizing & Redundancy Strategy: Properly sized equipment operates at optimal efficiency points. N+1 redundancy provides adequate backup without grossly oversizing systems that run inefficiently at low loads. Our designs ensure equipment operates in peak efficiency ranges across expected load profiles.
Real-world results from our deployed facilities consistently achieve PUE of 1.10-1.18 for liquid-cooled AI infrastructure in temperate climates, with some facilities reaching PUE below 1.10 during optimal conditions.
Redundancy requirements vary based on workload criticality, financial impact of downtime, and budget constraints. Here's how we guide clients through this decision:
N+1 Redundancy (Most Common for AI Training): Central plant includes one additional chiller, pump, and cooling tower beyond what's required for full load. This configuration protects against single equipment failures while balancing capital cost and reliability. During maintenance events, one piece of equipment can be offline without impacting operations. This approach is standard for most AI training facilities where brief interruptions (15-30 minutes during failover) are acceptable. Capital premium: ~15-20% over base capacity.
N+2 Redundancy (Higher Reliability): Two pieces of backup equipment for each system type. Provides protection against multiple simultaneous failures or maintenance during equipment failure. Recommended for facilities with aggressive uptime SLAs or where workload interruptions cause significant financial impact. Capital premium: ~30-35% over base capacity.
2N Redundancy (Maximum Reliability): Completely independent, parallel mechanical systems each capable of 100% facility load. True fault-tolerant design where one entire system can fail or undergo maintenance without any impact on operations. Typically reserved for hyperscale inference infrastructure, financial services, or other workloads requiring five-nines (99.999%) uptime. Capital premium: ~90-100% over base capacity.
Distributed Redundancy: For multi-building campuses, we often recommend distributed plants where each building has dedicated mechanical systems. While individual buildings may be N+1, the campus benefits from geographic separation and isolation of failures.
AI Training Considerations: Unlike traditional datacenters, AI training workloads can often tolerate brief interruptions since training jobs checkpoint frequently. Many hyperscale operators find N+1 redundancy adequate, investing the capital savings into additional compute capacity. However, inference workloads serving production applications typically require N+2 or 2N designs due to real-time latency requirements.
We help clients model financial impact of downtime against redundancy costs, providing ROI analysis supporting optimal decisions for their specific requirements.
Yes, many existing datacenters can be retrofitted to support AI workload densities, though feasibility and cost-effectiveness depend on existing infrastructure capacity and building constraints. Here's our evaluation framework:
Central Plant Capacity Assessment: First, we evaluate whether existing chillers, cooling towers, and pumps have available capacity for increased thermal loads. Traditional datacenters designed for 5-10kW per rack density often have 50-70% of plant capacity available, allowing significant densification without central plant upgrades. If capacity is exhausted, we assess space for additional equipment and structural capacity for increased loads.
Facility Water Distribution: Existing chilled water piping, pumps, and expansion tanks must be evaluated for increased flow rates and pressure drops. Many facilities require upgraded pumps and larger diameter piping for liquid cooling distribution. We analyze hydraulic performance ensuring adequate flow delivery to all zones at target densities.
Rack-Level Infrastructure: Air-cooled facilities typically require complete replacement of CRAH units, addition of containment systems, and enhanced airflow management for 20-30kW densities. For liquid cooling, facilities need new CDU installation, rack manifold distribution, and quick-disconnect connections at each rack. We design phased approaches where high-density zones deploy liquid cooling while existing air-cooled zones remain operational.
Electrical Infrastructure: Increasing rack density often requires electrical upgrades including transformers, switchgear, UPS systems, and busway/whip capacity. We coordinate mechanical and electrical upgrades ensuring integrated design.
Building Constraints: Structural capacity for heavier equipment, ceiling height for equipment access and maintenance, and floor loading for increased rack weights all require evaluation. Most existing facilities can accommodate modifications, but extreme densities may be limited by building constraints.
Phased Approach: We typically recommend phased retrofits starting with pilot zones proving concepts before full-facility conversion. This minimizes operational disruption and allows iterative refinement.
Cost Considerations: Retrofit economics vary widely (typically $3-8M per MW of increased capacity) depending on existing infrastructure condition and density targets. We provide detailed feasibility studies and cost-benefit analyses helping clients decide between retrofit versus new construction.
Total installed costs for mechanical systems vary significantly based on cooling architecture, redundancy level, site location, and project delivery method. Here are typical ranges for budgeting purposes:
Air-Cooled Systems (10-20kW/rack):
Hybrid Air/Liquid Systems (30-50kW/rack):
Direct-to-Chip Liquid Cooling (100-200kW/rack):
Cost Variables:
Important Notes: These figures include all mechanical equipment, installation labor, controls, commissioning, but exclude building shell, electrical infrastructure, IT equipment, land, and soft costs. Total project costs including these components typically run $8-15M per MW for complete AI datacenter facilities.
