01 — Who this is for
Five professionals. One building. Very different questions.
Every module teaches the same engineering through five perspectives — so the operator, the fund manager, and the compliance lead all leave with what they actually need.
Declan
Ops Manager
“Which breaker feeds which PDU at 3am?”
Ann
Fund / Asset Manager
“What does PUE 1.6 mean for our valuation?”
Mark
MEP Engineer
“Show me the standards reference.”
Sarah
ESG Analyst
“Are we CRU compliant by the deadline?”
Tom
QS / Cost Manager
“What’s the lifecycle cost?”
02 — Learning method
Six content tabs plus Progress. One engineering system. Fully explained.
Each module has six content tabs plus a Progress tracker. The Trivium (Grammar → Logic → Rhetoric) is the core teaching structure inside the Learn tab. The Visual Guide, Field Challenges, Assessment, and The Story tabs complete the learning cycle — from understanding, to seeing, to applying, to being tested, to reading it in narrative.
1
System Overview — the chain at a glance
The opening tab maps the full engineering chain — nine levels from first principles to investment committee language. The Cascade Calculator runs live bottleneck detection: enter target rack density and PUE, and every level shows PASS or FAIL. Click any level to read the plain English summary and open it in the Learn tab.

2
Learn — the Trivium in three stages
Grammar defines every term three ways — plain English, by the numbers, and technical definition with standards references. The Feynman Clarify button cycles through analogy, first principles, and a self-test. Logic builds cause-and-effect chains with Weakest Link analysis. Rhetoric shows how Declan, Ann, Mark, Sarah, and Tom each see the same engineering fact differently.

Visual Guide — how it actually works
3–5 interactive engineering diagrams per module showing system states, failure modes, and design logic step by step. Each diagram passes the Feynman Test: it explains something that text alone cannot. Step through a UPS failure. Watch a free cooling switchover. See what happens when hot aisle containment fails.

Field Challenges — apply it at Clonshaugh
Nine engineering challenges per module, one per level. Each challenge puts you on site at Clonshaugh with a specific problem to solve — real parameters, real numbers, real constraints. A Show the Fix button reveals the step-by-step worked answer with sourced numbers and persona perspective. These are not textbook questions. They are the questions a 10-year DC professional would actually face.

Assessment — three tiers of testing
Tier 1 Knowledge Check tests factual recall — definitions, thresholds, standards. Tier 2 Calculation tests whether you can work through the numbers (PUE, energy, cost, payback). Tier 3 Professional Judgement tests decision-making under constraint. Complete all content for an Engagement certificate (2 learning hrs). Score 80% overall for Completion (3 learning hrs). Score 90% for Achievement (4 learning hrs).

The Story — the chapter that brings it to life
Each module includes its companion chapter from The Data Centre Clock — a 15-chapter business novel set at fictional Clonshaugh DC. Five professionals discover the same engineering you just learned, but through narrative. The chapter loads directly inside the module — no separate app, no context-switching. Read it after the assessment to see the engineering in action.

09 — Questions
Frequently asked
DC-LEARN serves five professional audiences who interact with Irish data centres: Operations managers responsible for day-to-day facility management and CRU reporting; Fund and asset managers with DC assets in their portfolio; MEP engineers working on retrofit or new-build projects; ESG and sustainability leads managing EU Taxonomy, EED, and CRU obligations; and QS and cost managers preparing capital budgets or reviewing retrofit proposals. Every module is written to speak to all five — the same engineering, five different perspectives on why it matters.
Uptime and CNet are international programmes. DC-LEARN is built specifically for the Irish retrofit market — CRU/2025236 obligations, SEAI emission factors, ESB Networks connection tiers, EPA IE Licence thresholds, and Irish carbon tax trajectories (currently €71/tCOâ‚‚, rising to €100 by 2030). You will not find a module on CRU annual energy reporting or the 80% renewable obligation in a generic international DC course. DC-LEARN also costs a fraction of Uptime ATD (US$4,985 for five days) or CNet CDCDP (five days, price on application), with Irish-specific content and lifetime access.
Yes. Each module awards a verifiable certificate on completion. Engagement certificates are awarded for completing all content (2 learning hours per module, no assessment). Completion certificates require an assessment score of 80% or above (3 learning hours per module). Achievement certificates require 90% or above (4 learning hours per module). Full series: up to 32 hrs Engagement / 48 hrs Completion / 64 hrs Achievement. Certificates are verifiable at learn.legacybe.ie/verify with a unique certificate ID. Engineers Ireland accreditation application is in progress for Q3 2026.
No. Each module opens with Grammar — plain English definitions before any numbers or standards. The Trivium structure (Grammar → Logic → Rhetoric) is designed so that a fund manager can work through Grammar and get full value, while an MEP engineer can push through to Rhetoric. You follow the path that matches your role. The Feynman Clarify button at every level will re-explain any concept three ways until it lands.
If you purchase Professional access and the programme is not what you expected, request a full refund within 14 days — no questions asked. The only exclusion: if you have completed more than 50% of the paid modules, the refund window closes. Refunds are processed within 5 working days via Stripe. See terms and conditions for full details.
Yes. The Professional tier (€995 founding / €1,995 standard) is a single invoice — straightforward to put through as professional development. The Corporate tier (€9,500/yr for 10 seats) includes team progress tracking and bulk certificates, which makes it easy to report learning activity to HR or compliance teams. If you need a formal quote or purchase order raised, contact us.
DC-LEARN is standalone. It teaches you enough to ask better questions and make more informed decisions about your facility, whether you work with LBE or not. If you want LBE to assess a specific data centre, that’s a separate conversation — talk to an engineer about your situation.
