For you
Taking Building Management Systems (BMS): HVAC Control, BACnet and Building Automation from the United States
- Free in the United States, as everywhere, and self-paced: lessons, notes and the final assessment are open at any hour, so your time zone and shift pattern do not matter.
- The optional certificate for learners in the United States is a one-off US$23.99. What you get for it
- Plants across the Americas most often run Allen-Bradley, Siemens and Inductive Automation; each has its own free course to take next.
- See automation and engineering jobs in the United States, and what the industry looks like in Houston, Detroit and Chicago.
- EDWartens also has a regional site for the United States, for classroom training and local support: edwartens.com/us.
The course project · about 18 hours
Six-floor IT office BMS: points list to signed commissioning scripts on BACnet
Design and document the BMS for a six-floor office in Bangkok: two 250 TR chillers with pumps and cooling towers, six VAV air handlers with trim-and-respond resets per ASHRAE Guideline 36, 72 VAV boxes on MS/TP, exhaust fans and a fire-alarm interface, supervised from Desigo CC. You deliver the points list, the sequence of operation, the network architecture, a BAC0 simulation that proves the resets, and your own commissioning record. The sample pack shows what a controls contractor submits to the consultant.
Sample document pack, 8 documents, filled in for the scenario

- Control narrativeSequence of Operation: AHUs, VAV Boxes and Chiller Plant (ASHRAE Guideline 36)

Requirements
- Who it is for
- Beginner. For electrical, HVAC and automation engineers moving into buildings.
- Software
- Python 3 with BAC0 for the BACnet modules (free); any BMS front end is optional. What to download, and how
- Hardware
- None required. A BACnet/IP simulator or a small DDC controller helps with the Python modules.
Software you need
What to download, where from, what it costs and how to install it. Every link goes to the maker's own site, never a mirror.
Any BMS front end is optional.
Required
- 01Free
Python
Python Software Foundation
- Runs on
- Windows (not Windows 7 or earlier), macOS and Linux. Windows builds for x64, 32-bit and Arm64.
- Account
- None needed
Python is free, open source software. You can use it for learning and for commercial work at no cost.
Steps
- 1.Open python.org/downloads and click the download button for your system.
- 2.On Windows, run the Python install manager (or the classic 64-bit installer) you downloaded.
- 3.If you use the classic installer, tick "Add python.exe to PATH" on the first screen, then click Install Now.
- 4.Open a new Command Prompt or Terminal and run: python --version (on Windows you can also run: py --version).
- 5.Install packages with pip, for example: python -m pip install requests
- pip comes with Python. Run it as python -m pip so it always matches the Python you are using.
- Python.org now recommends the Python install manager on Windows. If it offers to add its folder to PATH, say yes so the python command works everywhere.
- Make a virtual environment for each project: python -m venv .venv

BAC0
Christian Tremblay (open source project), a Python or npm package
- Runs on
- Windows, macOS or Linux with Python 3.10 or later
- Account
- None needed
Free, open source under the LGPL v3 licence.
Steps
- 1.Install Python 3.10 or later and create a virtual environment.
- 2.Run: pip install BAC0
- 3.Open the documentation at bac0.readthedocs.io and follow "How to start BAC0".
- 4.Connect to a BACnet/IP test device or simulator and read a property.
- BAC0 is asynchronous and uses BACpypes3, so your scripts use async and await.
- BACnet/IP uses UDP port 47808. Allow it through your firewall on the lab network only.
- Only write to controllers in a lab or with written permission. Writes can change real building equipment.

A shareable EDWartens certificate
Finish every module and pass the final assessment, and the optional EDWartens certificate is yours. It carries a unique verification code on a public page anyone can check, so it stands up when a recruiter looks it up. See it below.
The course itself stays free whether or not you ever buy one.
Stuck? Ask a practising engineer
A free course usually means a comment section and hope. This one does not. Every module has an Ask-your-trainer panel that reaches the same engineers who teach our paid programme: people who commission panels for a living, not moderators.

PLC programming · FreeSiemens TIA PortalFrom zero electrical knowledge to a working, simulated S7-1200 program, for nothing.
PLC programming · FreeSiemens TIA Portal in Three HoursThe first three hours of the Siemens TIA Portal course, cut to end on a win: what a PLC is, how it is wired, a project configured in TIA Portal, and your first ladder program running in simulation. Finish it in an evening or two, earn a certificate, and carry straight on into the full course.
PLC programming · FreeTIA Portal: Build a MachineOne machine, start to finish. Take a bottle filling line from a written specification and an I/O list to a structured S7-1200 program with a fill station, a capper, a reject sorter and an operator screen with alarms, then test it against a written record and archive it for hand-over. The lessons are the reference; the machine is yours, and it is what you submit.
Instrumentation · FreeInstrumentation for PLC EngineersThe half of the loop that is not code. Follow one measurement from the transmitter in the field, down the 4-20 mA loop, into the analog card, through NORM_X and SCALE_X into engineering units, out again to a valve, and back to the control room when the reading is wrong.More free courses: Free BMS and building automation courses · Free data centre courses

Common questions
Which BMS brands does this cover?
The concepts apply to Honeywell, Siemens Desigo, Johnson Controls Metasys, Schneider EcoStruxure, Trane and Distech; the Python modules use open BACnet.
Do I need to know Python?
No. The BACnet modules start from installing Python and explain each construct as it is used.
Is HVAC knowledge required?
No. The HVAC applications module explains each plant item before its control.
Is the Building Management Systems course really free?
Yes. Every module, practice task and assessment. You create an account so your progress is saved and the assessments can be marked. The certificate is the only paid item, and only if you want it.
What certificate do I get, and is it a vendor qualification?
An EDWartens Certificate of Completion, issued when you pass the final assessment, with a verification code anyone can check. It is not a vendor credential and is never described as one.
Who made the video lessons in the Building Management Systems course?
The creators named in the Credits block at the foot of this page, on their own YouTube channels. EDWartens did not make the videos and the creators are not affiliated with EDWartens. What EDWartens wrote is the study plan, the notes, the practice tasks and the assessments.
