Engineering you can see through.
Training and software for better engineering decisions. Every number shows where it came from. Every answer shows its working.
Don’t just give the answer. Prove why it deserves to be trusted.
Thirty years of building services, turned into a course and a piece of software. Both follow that one rule.
DC-LEARN
Live nowThe Data Centre Clock is already ticking.
Eight clocks, six of them law, are closing in on Ireland’s existing data centres. Walk one building from the grid to the rack, and learn what each rule demands, what it costs, and how to engineer the answer.
Open DC-LEARNSixteen modules, from the grid connection to the rack. Four hundred and eighty assessment questions. The first three modules free, with no account.
Up to 48 learning hours. A certificate anyone can check, with stated learning hours for your own professional development record.
Example screen. Option names and results are made up, not from a real project.
The Glass Engine
In developmentSee every step.
Software in development. It will compare building services options, pick the strongest, and show the evidence, assumptions and checks behind that pick, so you can see why it deserves trust. Missing evidence will be flagged, never guessed. A failed safety check will always win.
Join the waitlistPick any number. See where it came from.
Each figure shows its source, how solid it is, and the mistake people usually make with it. This is how every number in DC-LEARN works.
How solid: Verified is law, official data or a standard. Industry is reputable industry data. Estimate is a screening estimate. Judgement is professional judgement with no published source.
Every figure in DC-LEARN works this way. Regulator sources are checked every week, and every change is checked automatically before it goes live. See the method on a full worked example
The questions people actually ask about a building.
DC-LEARN answers them for six professionals who work on the same data centre.
- Which rules reach this building, and when? the ESG analyst
- How much of this capacity can we actually sell? the operator
- What does an efficiency score of 1.6 mean for our valuation? the fund manager
- What is the lifecycle cost? the cost manager
Each answer is built from one rulebook, watched for change, and checked automatically before it goes live.
