AI Engineering Assistant
Ask Why. Get the Cause.
A surprising payback, an electricity figure that looks too high, a report line you need to defend. The AI Engineering Assistant built into CogenS™ reads your project and the model’s record of your latest run, then explains the result in plain engineering terms — with your numbers.
Why is my annual gas cost so much higher than our actual bills?
The gas rate on this project was left blank, so the run priced every unit of gas at the default rate for your city rather than your contract rate.
The fuel the boilers burned is consistent with your load and their efficiency — it is the price per unit driving the cost. Enter your contract rate on the Utility Rates page and run the model again.
Why It Matters
The Model Gives You the Number. The Assistant Tells You Why.
An 8,760-hour simulation makes thousands of decisions: how equipment stages, which curve applies, what a tariff charges in each hour, where a default fills a gap. When a result surprises you, finding the one decision behind it can take an afternoon of digging.
The assistant goes straight to the evidence. It compares what you entered against what the model actually used, finds the difference, and walks you from cause to result — so you can fix an input with confidence, or defend a number to a client knowing exactly where it came from.
Ask It Anything About Your Project
The Questions Engineers Actually Ask
“Why is my simple payback longer than the last run?”
“Why is the chiller electricity so high for this load?”
“What does the levelised cost of heat on my report include?”
“Which inputs would I change to test a thermal storage tank?”
“Why does my boiler run at such low part load in summer?”
“Compare the NPV of my last three projects.”
What It Does
Grounded in Your Work, Not in Guesswork
Explains Your Results
Each model run leaves a record of what the simulation actually did. The assistant reads it and traces a surprising number back to its cause — a blank field that fell back to a default, a unit read differently, a value held at a physical limit, a warning the run raised.
Answers With Your Numbers
It opens your saved project — location, equipment, rates, financial settings and results — before it answers. You get your figures explained, not a textbook range.
Knows the Platform Inside Out
What an input does, how a mode changes the simulation, what a report figure is made of. The assistant looks up how CogenS™ actually behaves instead of guessing.
Engineering Concepts in Context
NPV, IRR, levelised cost, part-load efficiency, demand charges — explained against your own project, so the concept and the consequence arrive together.

Built for Engineering Work
An Assistant You Can Put in Front of a Client
Engineering answers have to be traceable. The assistant is designed around that.
A reader, not a calculator
The assistant explains what the platform has computed. It never invents a what-if figure: if you need a number the model hasn't produced, it tells you which input to change and asks you to run it.
Private to your account
It reads only projects that belong to you. Access is fixed by who is signed in, so no question can make it read another user's work.
Honest when it doesn't know
It is built to say it has no reliable answer rather than guess — and to point you to a bug report when a result looks genuinely wrong.
A Direct Line to Engineering
Found a Problem? It Reaches the People Who Can Fix It.
The same panel carries Bug Report and Feature Requestforms that go straight to the CogenS™ engineering team — with the project you had open attached, so the team can reproduce what you saw without a back-and-forth.
Included With Every CogenS™ Plan
Paid plans include unlimited assistant questions. The free tier includes 10, and the academic licence 50 per term — enough to see what it does on your own project.
