Engineering you can see through.
Training and software that show the evidence behind engineering decisions. Every answer shows its working.

Don’t just give the answer. Prove why it deserves to be trusted.
Thirty years of building-services experience, turned into training and 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.
The engine picked an option for a made-up office. Think it is wrong? Move the assumptions and see if the pick holds.
A teaching sketch with invented figures: 15-year cost in thousands of euro, building cost plus 15 years of energy and carbon. It shows the idea; it is not the Glass Engine’s real results.

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.
Pick any number. See where it came from.
Every figure shows its source, how solid it is, and where people often get it wrong. Pick one.
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, and regulator sources are checked every week. See it in a full module, free
