Start with your engineering task#
VentilatePro connects HVAC calculations and project records across the web app, ChatGPT, the command line, and other AI clients. Choose the workflow you need.
Connect the sidebar workspace, run calculators, and discuss results.
Find formulas, units, worked examples, and calculation limits.
Read room, zone, and AHU schedules with calculation freshness.
Install the command-line tool or configure an MCP client.
Choose an interface#
| Interface | Best for | Account |
|---|---|---|
| ChatGPT workspace | Six calculators, saved project results, engineering prompts | VentilatePro OAuth connection |
| Browser calculator | Psychrometrics, charts, exports | No login |
| CLI | Repeatable offline calculations and project automation | No login for local calculators; token for project work |
| General MCP server | Typed tools for AI agents and guarded project workflows | OAuth remotely; token for local project tools |
The ChatGPT workspace reads saved project values. Its six calculators and read permissions are a focused subset of the general MCP server.
Try a calculation#
Open the free browser psychrometric calculator, or install the CLI for a repeatable sensible-load check:
pipx install ventilatepro-cli
ventilatepro calc sensible-load --cfm 5000 --entering-dry-bulb 80 --leaving-dry-bulb 55 --json
Expected result: 135,000 Btu/h of sensible cooling, using 1.08 × 5,000 × (80 − 55). This uses standard-density air. It is a sensible-load check; whole-building loads require the project calculation workflow.
See air-load formulas and assumptions or the installation guide.
