01 — Who this is for
Six professionals. One building. Very different questions.
Every module teaches one piece of engineering through the six people who work on the same building. The facility manager, the fund manager, the engineer, the ESG analyst, the cost manager and the colo CTO each get the answer to their own question, and learn why the others ask theirs.
Declan
Facility 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?”
Niamh
CTO · Colo Operator
“How much of this capacity can I actually sell?”
02 — Learning method
See it. Learn it. Watch it work. Solve it. Prove it. Live it.
Every module takes you through the same six steps, each in its own tab. You see the whole system at a glance, learn it three ways, watch it work, solve real problems on site, prove it in a three-tier assessment, then read it happen in the story. A Progress tab keeps track of every step, so you can stop and pick up where you left off. An on-page tutor sits beside every module: ask it a question in your own words, or why an assessment answer was wrong, and it answers from that module’s own content.

The opening tab — 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.

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, Tom, and Niamh each see the same engineering fact differently.

Visual Guide — how it actually works
Interactive engineering diagrams in every 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 (3 learning hrs, with distinction).

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. Six 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.

06 — The Clock
Eight Clocks. One Building. All Connected.
Eight regulatory clocks are ticking on Ireland’s existing data centres. Inside the building a second clock is running: since 2013 the IT load has doubled, from 1,200 kW to 2,400 kW, on plant nobody touched. Nothing failed. Only the load moved. Explore any clock and trace its connections — or press play for the 60-second story.
Tap any clock to see its deadline — or press play.
- EU Taxonomy
- Activity 8.1: Code of Conduct practices, independently verified; refrigerant GWP ≤ 675. No numeric PUE threshold — PUE ≤ 1.3 is the voluntary CNDCP target.
- F-Gas EU 2024/573
- One regulation, two systems — R-410A on the roof, FM-200 in the fire suppression. 1,828 tCO₂-eq on site.
- CRU/2025236
- 80% renewable supply obligation — this building sits at roughly 40%.
- EED Article 12
- PUE, WUE, ERF and REF reporting to SEAI, due every 15 May.
- Carbon Tax
- €63.50 per tonne today, every fuel at €71 from 14 Oct 2026, €100 by 2030.
- EPA IE Licence
- Dormant until scale wakes it — conditional above 50 MW thermal.
- CRREM Pathway
- LBE-derived pathway — do-nothing misaligns around 2031.
- SFDR
- The fund’s Article 8 classification rests on this asset’s disclosures.
Eight regulations, drafted by different people in different years, all land on the same Irish data centres in the same decade. Nobody coordinated them — but the deadlines coordinated themselves. DC-LEARN maps every connection: the story teaches the why, the modules teach the how. Three chapters and three modules are free.

07 — Companion narrative
The book is inside every module.
A 15-chapter business novel set at fictional Clonshaugh DC, Dublin. Six professionals — a facility manager, a fund manager, an MEP engineer, an ESG analyst, a cost manager, and the CTO who has to sell the capacity — discover that eight regulatory clocks are already ticking on their building. Each chapter is built into its DC-LEARN module as The Story tab — no separate app, no context-switching.
Written as accessible business narrative — turning complex regulatory reality into a story you can follow. Learn the engineering, then read it in action.

09 — Questions
Frequently asked
DC-LEARN serves six 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; QS and cost managers preparing capital budgets or reviewing retrofit proposals; and CTOs and colocation operators selling capacity under SLA. Every module is written to speak to all six — the same engineering, six 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 €63.50/tCO₂, rising to €71 from 14 Oct 2026 and €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. One boundary stated plainly, because it is a deliberate difference rather than a gap: CDCDP goes deep on structured cabling, containment and bonding, and DC-LEARN does not cover that ground — a DC-LEARN certificate is not equivalent to CDCDP and is not offered as one. The sixteen modules are built for the people who commission, fund, operate and report on data centres rather than the people who cable them. DC-LEARN also costs a fraction of a five-day international course such as Uptime ATD or CNet CDCDP, with Irish-specific content and lifetime access.
A weekly automated watch checks the same regulator sources this course cites — CRU, SEAI, EirGrid, the EU's own registers, and more. When one of them moves, we update the sourced record first and regenerate every module that teaches that figure, usually within the week the regulator publishes the change — not at the next print run or the next cohort. Every number on screen carries its source and how well-established it is (Verified, Industry, Estimate, or Judgement), so you can see the difference between a settled figure and a screening assumption for yourself. Updated when the regulator moves, not when the brochure reprints.
Checking regulator sources…
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 (3 learning hours per module — the distinction is recorded on the certificate). Full series: up to 32 hrs Engagement / 48 hrs Completion or Achievement. Each certificate carries a unique certificate ID and can be checked against the LBE register at learn.legacybe.ie/verify. Learning hours and assessment scores are stated on every certificate for self-directed CPD recording.
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 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 full DC-LEARN Practitioner path (€495, ex VAT) is a single invoice — straightforward to put through as professional development, and individual module certificates (€49) are small enough for most self-approval limits. The Corporate tier (€9,500/yr for 10 seats, team seats from €39 per module) 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.
