One site. One decision.

First Site Evaluation

A paid, scoped assessment using Headroom software for one site and one decision. Describe your site question by email first; a written quote follows once the supported scope and suitable records are confirmed.

Standard assessments: Written finding within five business days after scope is agreed and the required records are confirmed. Broader assessments, including coupled power-and-cooling work, follow the schedule agreed in the written quote.

An answer you can examine together.

Start with a fit discussion about one site and one decision. The assessment uses company-authorized exports only after scope and handling are agreed. It produces a written finding, not external engineering approval.

A written finding

What the supplied evidence supports, where a constraint occurs, or why the conclusion remains unknown.

The basis for the decision

Relevant limits and margins, source references, assumptions and evidence gaps, with separate power, cooling and overall conclusions where applicable.

Next engineering actions

What to verify, reconcile or revise, together with technical evidence and replay materials appropriate to the agreed assessment.

How pricing works

Pipeline Screens are priced per portfolio. A First Site Evaluation is priced per site, based on scope, complexity and the proposed load. Quarterly reporting is available under an annual agreement, priced per site according to the agreed scope. Pricing and terms are subject to written approval before work begins. Fees are for the assessment, never for a favorable result.

Agree the scope before sharing records.

1. Initial fit discussion: Describe the decision, approximate proposed load, site arrangement, period and kinds of records available. High-level descriptions are enough to start; do not send operational records.
2. Scoping: Confirm the applicable method, boundaries and period, then agree the required records and who will provide site-engineer confirmation. The initial inquiry does not require a completed engineering package.
3. Authorization and records: Agree permitted use, recipients and handling before sharing exports. An analyst maps the records; the site engineer confirms that mapping, applicable inputs, conditions and assumptions. This confirmation role is agreed during scoping, not assumed from the prospect’s job title.
4. Report review: Discuss the finding, constraints, gaps and next actions. The assessment does not grant operating authorization or replace engineering review.

Start with the question, then the applicable records.

For the initial fit discussion, describe the categories you hold and any known gaps. The detailed checklist below is for the agreed assessment after scoping, not a prerequisite for making an inquiry. Do not upload or email operational records until authorized use, recipients and handling are agreed.

Boundary and proposal

Site and equipment arrangement, existing demand, proposed additional load and evaluation period.

Limits and obligations

Applicable electrical limits, energy or fuel evidence, reserves and higher-priority commitments.

Cooling and provenance

Air, single-phase liquid or mixed cooling, plus source ownership, units, timing, uncertainty and permission to use the records.

After scoping: detailed records and conditional additions

For every assessment

Site boundary and relevant equipment, with diagrams or records that locate each measurement and limit.
Baseline and proposed load profiles for the stated period; supplied evaluation periods where comparison is needed.
Applicable grid-import and equipment limits, protected obligations, reserves and their evidence.
Source identifiers and ownership, original units, timestamps, time zone, interval meaning, native resolution, gaps and uncertainty.
Written authority for the proposed use and sharing, plus the site-engineer confirmation agreed during scoping for the exact records, mapping, applicable inputs and assumptions.

For natural-gas evaluations

One already-running engine or turbine: exact applicable manufacturer operating points, electrical output and auxiliaries, gas-consumption evidence, delivery rate and finite allocation on a lower-heating-value basis, pressure and fuel quality, protected commitments and permitted operating period. Missing operating points are not filled by interpolation or assumed derating.

For grid/battery/diesel evaluations

One battery: usable starting DC energy, applicable charge/discharge limits and efficiencies, protected energy and supplied interval profiles. One already-running No. 2-D diesel generator: applicable rating, net-output and external-auxiliary profiles, fuel-consumption evidence, isolated closed-return tank inventory, unusable fuel, reserves, uncertainty and baseline protection. Generator and auxiliary profiles are constant within each modeled trajectory; applicable load and battery changes use aligned intervals.

For cooling assessments

Identify air, single-phase liquid or mixed cooling first. Define the IT boundary, relevant air path, any serial liquid interfaces, shared heat-rejection stage, and baseline and proposal conditions.

Electricity consumed: cooling-equipment electrical loads and how they reconcile with the native site-load profiles, without double counting auxiliaries.
Heat removed: thermal demand and removal evidence, capture fractions, temperature boundaries, flow and fluid-property evidence where applicable.
Applicable capacity: evidenced capacity at the stated conditions, protected service, uncertainty and source references. Observed heat removal is not a capacity rating.
Shared equipment: documented ownership, other loads, allocation and net capacity available to this boundary. Parallel equipment needs an independently reviewed aggregate, not automatic addition of nameplates.
Conditional engineering evidence: transport and flow limits, fluid and temperature compatibility, sink conditions and separately confirmed latent or condensation requirements where relevant. Confirm generator and battery heat are outside the assessed cooling and rejection boundaries; missing confirmation leaves the affected checks unresolved, while a known failure still produces Not supported. Without an established failure, unresolved required evidence leaves the overall finding Unknown.

Important limits on the records

Bills alone do not establish spare capacity. Neither do PUE, nameplate ratings or observed peaks alone. PUE is the ratio of facility electricity to IT electricity, not a measurement of available cooling capacity.

Interval averages can hide shorter peaks. Keep native export resolution and the documented time basis; there is no universal 15-minute requirement and no promise of continuous adequacy from averages.

No credentials requested. Headroom does not need equipment-control access. An analyst maps supported exports and reviews supporting documents; arbitrary PDFs and spreadsheets are not automatically converted into a valid assessment.

One site. One question. An agreed period.

First Site Evaluation

Review the records checklist and who develops Headroom. No sensitive records are needed for the initial inquiry.

Read-only, export-based and analyst-assisted. Findings apply to a supplied proposal, defined period and supported method; they are not operating approval or guaranteed capacity. Public capacity examples are synthetic. Customer-site validation and qualified external engineering review remain outstanding. Method boundaries and verification
