The BAS Claude Kit

Turn Claude into your BAS assistant. By tonight.

The skills, prompts and repos a BMS engineer uses on real controls jobs. Copy, paste, done.

By Bassirou, BMS engineer and founder of Structio.

Sound familiar?

The integrator who built the system retired. Nobody knows how to work on what he left behind.
Nobody really teaches this trade. You learned it by osmosis, and by trial and error.
You got a few weeks of training videos, then got sent to program a site on your own.
Every AI tool you tried either added steps or made things up. And it's your name on the job.
A meter reads 6 × 10⁻³³ kWh, and you lose an hour on the word order.

This is not another pack of 1,000 prompts.

Generic prompts give generic answers. This kit is 10 short chapters written for controls work: what to paste, where, and what you get back. A few tools, each one tested on BAS documents and on a simulated building.

How it works: paste a skill once, then ask in plain words. Claude follows your standards. The tedious work is exactly what AI should take off your plate. The decisions stay yours.

What's inside

1
Set up Claude for BAS work
Claude answers like a controls engineer, not a textbook. Fifteen minutes, once.
2
Your standards, given once
Every answer follows your naming convention and your abbreviations, on every job.
3
BACnet lab: practice on a simulated building, then talk to your controllers
You ask "What's the supply temp on AHU-1?" and Claude reads it from the controller.
4
Modbus lab: read a register map without the headache
Claude reads a meter and gets the scaling, the word order and the sign right, before you're on site.
5
Take over someone else's job
The program another integrator left behind, explained line by line, with what looks wrong.
6
Sequence to logic
A written sequence of operations becomes control logic, block by block, for your platform.
7
Hot and cold call triage
"Too hot on the third floor" becomes a troubleshooting tree and the exact values to check first.
8
BAS-safe AI rules
The line an AI must never cross on a live building. Paste it in your profile or your Projects.
9
Build your own skills
The method we use at Structio to turn any repetitive task into a skill.
10
Connect Claude to Structio
For when you want the riser diagram and the points list built for you.
+
Bonus: explain the scope to the owner
A 60-second video of your scope, made by Claude, without a video editor.

Before and after

From the Modbus lab. Same seven registers from an energy meter, read two ways.

Read straight

Energy  6.2e-33 kWh
Voltage 2301 V
PF      64.586

Read with the manual, by Claude

Energy  15,234.5 kWh  (low word first)
Voltage 230.1 V       (x0.1)
PF      -0.950        (signed: exporting)

The math

One register map read right before you drive out is one wasted trip you don't make. One hot call solved over the phone is one truck you don't roll. The kit costs less than the first coffee on site.
