BMS / Building AutomationDesign study in progress

BMS design study for a complex facility of approximately 1,750 points

Point-list structure, network architecture, integration strategy and commissioning plan for a large building automation system.

The case concerns the organisation of a large BMS design package, with approximately 1,750 planned control points and the need to coordinate HVAC, energy and water metering, alarms, schedules and third-party systems. The scope is automation design and implementation preparation—not the power electrical installation.

Technical challenge

Information originates from different specifications, drawings and subsystems. Without common naming, a clear point list and defined responsibility boundaries, the project risks reaching commissioning as a collection of disconnected open issues.

Approach and scope

  • Point-list structure by system, panel, zone and signal type.
  • Control narratives and sequences of operation for critical functions.
  • Integration matrix for BACnet/Modbus, VRF gateways, meters and third-party systems.
  • Network architecture, naming convention, alarm priorities, trends and historical data.
  • FAT/SAT, commissioning and documented acceptance plan.

Critical technical decisions

01

Separation of automation design from power wiring and electrical panels.

02

No energy-performance claim before commissioning and a period of real operation.

03

Every integration is treated as a controlled interface with clear ownership and a test case.

Deliverables and current status

The study is in progress. The deliverable is being organised as a single package containing the design basis, point list, architecture, sequences, integration matrix and commissioning checklist. No operational or energy result is claimed yet, because it can only be evaluated after implementation.

What this case demonstrates

A large BMS does not start with the selection of a controller. It starts with scope control, consistent information and the ability to test and hand over every function.
