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

School heating and hot-water plant on BACnet: weather compensation, legionella control and a BAC0 fault-detection logger
Re-control the heating and domestic hot-water plant of a secondary school campus in north-east Scotland: three condensing boilers in cascade, three weather-compensated or constant-temperature LTHW circuits, a 1,000-litre calorifier held at legionella-safe temperatures with daily destratification, and frost protection. Then write a BAC0 logger that reads the plant over BACnet/IP every minute and a set of fault-detection rules that show whether the boilers are really condensing. You deliver the points list, the sequence, the alarm list, the logger design, the commissioning record and the fault-detection report.

Software you need

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

- Runs on
- Windows, macOS or Linux with Python 3.10 or later

- 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.

FAQ
Common questions
What is BACnet?
BACnet is the open data communication standard that lets building automation devices from different manufacturers work together. BACnet International describes it as the global data communication standard for building automation and control networks, maintained by the ASHRAE committee SSPC 135; it is published as ANSI/ASHRAE Standard 135 and by ISO as ISO 16484-5. The course explains BACnet and then has you read and write BACnet points with Python.
What is KNX?
KNX is an open international standard for home and building control, widely used for devices such as lighting, blinds and heating controls. The KNX Association says buyers can choose from over 8,000 certified products from more than 500 manufacturers. The course covers BACnet, Modbus, LonWorks and KNX so you can tell which one a project is using and why.
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.
How long does the Building Management Systems course take?
Plan on about 20 hours in all, including the video lessons, notes and practice tasks. It is self-paced, so you work through the thirteen modules at your own speed.
Is the Building Management Systems course free in India, and what does the certificate cost?
Yes. Learning costs ₹0 in India: every module, the written notes, the practice tasks and the final assessment, with no card and no trial period. The only paid item is the optional EDWartens Certificate of Completion, ₹499 including GST for this beginner course, paid in rupees through Razorpay, and only if you want it after passing the final assessment.
