Engineering you can see through.
Two products for two kinds of building. DC-LEARN trains the people who work on Irish data centres. The Glass Engine, in development, helps engineers choose the building services for Irish offices. Both show their 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.

For data centres
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. Each total is the building cost plus 15 years of energy and carbon costs. It shows the idea; it is not the Glass Engine’s real results.

For offices
The Glass Engine
In developmentSee every step.
Software in development for engineers who design the building services for Irish offices: new shells, fit-outs and retrofits. It will compare the options, pick the strongest, and show the evidence, assumptions and checks behind that pick. Missing evidence will be flagged, never guessed. A failed safety check will always win. Your own engineer stays responsible and signs.
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
