Before signing, verify that power and compatible cooling will be available on schedule, examine resilience and operating evidence, and compare providers on the same technical and commercial assumptions.
Start with the workload you need to deploy
Build a written deployment profile before asking providers for proposals. A facility that suits one AI system may not suit another: power density, cooling interfaces, network topology, storage throughput, and availability expectations depend on the workload and equipment.
Record the technical and delivery requirements
- Workload type: training, fine-tuning, inference, or a mix.
- Accelerator system and generation, expected rack count, rack power density, and planned growth.
- GPU interconnect, external network capacity, latency needs, and storage capacity and throughput.
- Required availability, data location, security constraints, and target deployment date.
- Phased ramp schedule and the date by which each increment of capacity must be usable.
Clarify the service boundary, too. Identify who supplies and integrates servers, racks, cabling, liquid distribution, facility cooling, network, storage, monitoring, and 24/7 operations. ASHRAE’s data center energy-performance framework addresses planning through commissioning, operations, and retrofit; it calls for considering purpose, power, cooling, compute, location, impact, and scalability together. The framework is guidance, not a mandatory code or a replacement for local requirements.
Can the provider deliver usable power by your date?
Ask for firm, site-specific evidence of the capacity allocated to your deployment and when it will be energized. A campus-wide or utility megawatt figure does not establish how much IT capacity is available to your racks, or when it will be ready.

Request the evidence and define the commitment
- A site-specific one-line diagram or equivalent engineering documentation.
- The contracted IT capacity, with utility, site, facility, and IT load distinguished.
- Committed energization dates and phasing, plus whether each capacity increment is available now, contracted, under construction, or only planned.
- Utility coordination status, voltage, rack-level power-delivery limits, redundancy arrangement, and maintenance windows.
- A written remedy if delivery milestones slip, including the customer’s options if a delay makes the capacity unusable for the intended deployment.
Ask how the facility will handle the workload’s power variation, not only its steady-state demand. Large synchronized changes in AI load can matter to site operations and grid coordination. ASHRAE’s Integrated Design Principles describes AI rack densities of approximately 120 kW to several hundred kilowatts per rack, with megawatt-class racks anticipated near-term. That is contextual guidance, not a universal specification or a measured market census; use the requirements of your selected system.
For a product-specific scale point, NVIDIA’s DGX SuperPOD GB200 reference architecture, updated November 19, 2025, describes one scalable unit as eight DGX GB200 rack systems with a total TDP of 1.2 MW. This figure applies to that named reference configuration, not to other systems or a generic AI rack. Confirm the relevant power envelope with the equipment supplier and site engineers.
Will the cooling system work with your exact hardware?
Do not treat air cooling, direct-to-chip liquid cooling, or a provider’s “liquid-ready” label as proof of compatibility. Ask the provider and equipment supplier to confirm that the facility’s design conditions match the selected server and rack, and that the required loop will be operational by the committed date.
For liquid-cooled deployments, pin down the loop boundary
- Where the facility water system (FWS) ends and the technology cooling system (TCS) begins.
- Permitted supply and return temperatures, flow rates, and operating limits.
- Who supplies and operates heat exchangers, coolant distribution units (CDUs), pumps, and controls.
- Water or coolant chemistry, filtration, monitoring, leak detection, isolation, and containment.
- Service access and responsibility for maintenance, repairs, and response to a pump, CDU, or heat-rejection failure.
- Whether the design supports mixed air- and liquid-cooled equipment and how it handles changes to the deployment.
Also ask about the heat-rejection method and local conditions: climate, dry-cooler limits, humidity, any evaporative or adiabatic water use, and possible heat reuse. ASHRAE recommends technology cooling systems for purpose-built high-density AI facilities and matching the cooling strategy to the density. Its GB200 SuperPOD reference describes a hybrid direct-liquid and air-cooling design; that example is specific to the reference architecture, not a requirement for every AI deployment.

How resilient is the facility, and what does the contract promise?
Review the failure and maintenance plan across the whole service path. Trace utility feeds, transformers and switchgear, UPS, generators or alternate supply, cooling distribution, controls, and network routes. Ask where components or paths are shared, how maintenance bypasses work, and what remains available during maintenance or an incident.
Test the design claim against operating evidence
- Request design documentation and commissioning evidence for the systems serving your capacity.
- Ask about fuel or energy duration and replenishment, equipment testing, spare parts, incident response, and planned maintenance.
- Request recent availability history and require the provider to define its measurement boundary.
- Review staffing, escalation paths, notification duties, and customer access to incident information.
Put availability expectations into the service agreement. Define the covered service, measurement method, exclusions, notification requirements, credits or other remedies, treatment of chronic failures, and termination rights. A facility tier or design certification can inform due diligence, but it does not replace workload-specific service terms.
NVIDIA’s GB200 reference recommends a Tier 3 design or equivalent, including concurrent maintainability and no single point of failure, and cites Uptime Tier 3 or equivalent TIA/EN design requirements for that deployment. This is guidance for that vendor reference architecture; it does not establish that a particular provider is certified or that its SLA meets your needs.
Compare efficiency and environmental claims on equal terms
Ask whether each performance figure is a design estimate or measured operational result. For measured figures, request the reporting period, facility boundary, instrumentation, calculation method, IT load and utilization, and weather normalization where relevant. Without comparable conditions, a favorable number is not a sound basis for ranking sites.

Use more than one metric
| Measure | What it helps assess | What to request |
|---|---|---|
| PUE | Facility energy overhead relative to IT energy use. | Boundary, reporting interval, calculation method, operating load, and whether the figure is measured or a design estimate. |
| WUE and WUI | Water performance and water-related impact. | Method, water source, consumption versus withdrawal, cooling mode, and relevant site constraints such as drought restrictions. |
| CUE | Carbon-related performance. | Calculation method, emissions assumptions, reporting boundary, and period. |
| ERE or ERF | Energy reuse, where the provider claims useful heat export. | Exported useful energy and the basis used to calculate the metric. |
ASHRAE lists PUE, WUE, WUI, CUE, DCRE, and IT work capacity and utilization among relevant measures. PUE alone does not establish water or carbon performance. ASHRAE’s Integrated Design Principles gives an illustrative comparison of PUE near 1.10 versus roughly 1.4 to 1.6 for traditional designs. Treat that as the framework’s example, not a like-for-like result: the figures are not stated as having identical load, climate, or measurement conditions. Site conditions and IT load also affect water use, so comparisons across locations can mislead.
Require commissioning, operational readiness, and room to grow
Capacity is not ready for your workload simply because a building or power block is complete. Agree on an integrated commissioning and acceptance plan before deployment. It should cover electrical and cooling systems, IT equipment, network, controls, alarms, and load behavior.
Make acceptance testable
- Set objective pass/fail criteria, responsible parties, and customer witness rights.
- Define defect correction and retesting, along with the remedy if acceptance criteria are not met.
- Confirm access to monitoring and reporting, preventive-maintenance schedules, incident escalation, and change control.
- Verify that the operations team has the skills and procedures needed for the chosen cooling design, including liquid-cooling response where applicable.
- Ask how additional capacity or a retrofit can be delivered without stranding the installed deployment.
ASHRAE treats commissioning as a validation phase and operations as continuing monitoring, maintenance, and energy management. Ask for records that show how the provider will carry those activities out at your site, rather than relying on a generic statement of capability.

How should you rank providers?
Weight the comparison according to the workload rather than applying a universal score. A deployment with a fixed near-term launch date may place more weight on proven, deliverable capacity; a liquid-cooled system may make loop compatibility and operating capability decisive. Consider these axes together:
- Power available by the required date, with credible expansion capacity.
- Compatibility with the actual hardware, rack density, cooling design, network, and storage needs.
- Resilience design, maintenance arrangements, and enforceable service commitments.
- Measured energy, water, and carbon reporting with clear methods and boundaries.
- Commissioning quality, operational support, and adaptability as the deployment changes.
- Geography, grid constraints, water availability, climate, permitting, total contract cost, and exit flexibility.
Use evidence quality as part of the decision: a claim with a defined boundary, date, operating condition, and accountable contractual commitment is more useful than an unqualified capacity or efficiency headline. Building, electrical, environmental, water, and permitting requirements remain specific to the site and jurisdiction. The PNNL/ASHRAE/NEMA AI Data Center Energy Performance Framework is guidance; it does not establish mandatory requirements or supersede applicable codes and standards.
