Launching October 15, 2026 · Demos open now

Mechanical design, from loads to deliverables, in one workspace.

AIM Works connects peak loads, ASHRAE 62.1 ventilation, equipment and plant sizing, compliance checks, Design Review, and engineering deliverables — with an AI co-pilot that drafts changes for you to approve.

Built for mechanical consulting engineers. Methods cited. Assumptions visible. Every AI change requires engineer approval.

The workspace

One project. Every step reads from it.

Your scope runs down the left. The calculation, its method, and its maturity label sit in the middle. Design Review findings and the AI's proposed changes wait on the right until you accept or reject them.

Wireframe of the workspace layout — not a screenshot, and no computed values are shown. You'll see the live product, on your own project if you bring one, in the demo.

Worked project

See a mechanical project move through AIM Works.

Each step reads the one before it. Nothing is re-keyed, and every result carries its method and a maturity label that says how far it has been checked.

Reference checks behind the Validated label

A module earns Validated only when its result is checked against a reference value. These comparisons are pinned in the automated test suite and re-run on every change.

Engineering trust

The math is deterministic. The AI doesn't do the engineering.

Calculation engines produce every number. The AI sets up projects, drafts changes, and explains findings — it never originates a result.

Deterministic engines

Loads, ventilation, psychrometrics, and sizing run through coded methods. The same inputs give the same outputs, every time.

Cited methods

Each result names its method and code edition — RTS per ASHRAE HOF 2021, ASHRAE 62.1-2019 §6.2, ASHRAE 90.1-2022 efficiency tables.

Visible assumptions

“Show calculation” opens the equation with your values substituted. Assumptions and limitations go into the report appendix.

Engineer approval

Anything the AI wants to change is queued as a Pending Change. Nothing touches your project until you accept it.

ASHRAE 140 Compliant

AIM Works meets the applicable ANSI/ASHRAE Standard 140-2023 acceptance criteria for its tested building-performance simulation capabilities.

View validation methodology →

Validated

Checked against a reference value, with the citation shown. Earned per module, never assumed.

Advisory

A real calculation from published methods. A design starting point, with assumptions and limitations disclosed.

Reference

A checklist or scoping tool keyed to your project data. Never presented as an engineered result.

AIM Works outputs are advisory. They support the engineer's design; they don't replace engineering judgment. Every project must be reviewed and stamped by a licensed Professional Engineer before construction. Read the methodology →

Workflow

Six steps, one project state.

1
Set up the project
2
Build spaces, zones, and design criteria
3
Run loads and ventilation
4
Size equipment and plant
5
Run Design Review
6
Export deliverables
What's different

Three things we built around.

One connected project state

Design conditions, rooms, loads, ventilation, equipment, and plant all read from the same project. Change a zone and the steps downstream are flagged for re-run, instead of drifting out of sync across files. Scope is set per project, so it fits the common consulting project types: offices, schools, clinics, multifamily, tenant fit-outs, and central plants.

AI that proposes, engineer who decides

Describe the project and the co-pilot drafts the scope, zones, and design conditions. Ask it to add equipment or re-run a calculation and it queues the change for review. You accept or reject each one, and the calculation engines, not the model, produce the numbers.

Transparent, traceable calculations

Every result shows its method, code edition, and maturity label. “Show calculation” opens the substituted equation. The calculation package records where each number came from and how far it has been checked, so a reviewer can follow the chain.

Why it exists

Built by a mechanical engineer.

AIM Works started from a problem I kept running into as a mechanical engineer: the engineering wasn't the hard part — the workflow was. Loads in one tool, ventilation in a spreadsheet, equipment selections somewhere else, and the reasoning behind each number scattered across all of them.

AIM Works connects those steps in one project, so the engineering reasoning carries from setup through deliverables, and the engineer stays in control of every change.
