Building Management System (BMS/BAS) Graphics for HVAC Systems and Building Operations

BMS Graphics for HVAC Systems and Building Operations

BMS graphics are the visual screens used to monitor and operate a Building Management System. They bring equipment diagrams, temperatures, operating status and other available control points into a view that helps facility teams understand their HVAC systems.

For a controls contractor, a useful graphic must match the installed equipment and its control sequence. For an operator, it should make the next step clear: identify the affected system, check its current condition and investigate the relevant alarm or trend.

What BMS graphics should show

A building may have air handling units, rooftop units, VAV boxes, fan coil units, pumps and central plant equipment. Each system needs a screen suited to the way it operates. An AHU graphic, for example, should help the operator follow the airflow path and locate the sensors, dampers, coils and fan.

Depending on the installed controls and available points, an AHU screen may display fan command and proven status, supply air temperature and setpoint, cooling valve command, damper position, filter alarm and operating mode. Label commands and feedback separately. A valve command of 100% does not confirm that the physical valve is fully open unless position feedback is available.

Choosing between 2D and 3D HVAC graphics

A 2D schematic is useful when the priority is a compact view of the system and its control relationships. Custom 3D HVAC graphics can help users recognise equipment and understand the arrangement of its components. The appropriate format depends on the operator, display size and complexity of the installation.

Whichever style you choose, keep live values readable. Equipment labels, units and alarm indications should remain easy to find without being hidden by decorative details.

An example of useful AHU graphics

Consider an illustrative AHU screen showing a supply air temperature of 18°C against a 13°C setpoint, a cooling valve command of 100% and a proven running fan. These values show that the controller is requesting cooling while the measured supply air temperature remains above setpoint.

The graphic can help the technician decide what to check next, such as chilled water availability, valve operation, sensor accuracy or the recent temperature trend. Those displayed values alone do not establish the cause. A well-designed screen supports investigation by presenting the relevant information together.

Connecting floor plans with equipment screens

BMS floor plan graphics help operators locate rooms, HVAC zones and equipment. Where the platform and point data support it, a room or zone can link to the relevant VAV, FCU or AHU screen. Thermographic views can also show temperature conditions using defined colour ranges and a visible legend.

Plan the navigation around the building: start with a building overview, select a floor, locate the affected zone and open its equipment screen. This helps users relate a comfort complaint to the system serving that area.

Graphics integration and point binding

A static equipment image and an operational BMS screen are different deliverables. Live values require the screen to be connected to the correct control points. Animations, alarm links, trend links and operator commands also need configuration in the target platform.

Before work begins, agree whether the package includes image creation only, complete screen development, database point binding or integration testing. Platform version, licensing, access permissions and available data affect what can be delivered.

What to provide for a graphics project

Useful inputs include the controls submittal, equipment cutsheets, sequence of operation, equipment tags and the BMS database or point list. Floor plan work also needs the relevant drawings and zone identification. Share the target platform and version, screen requirements and preferred navigation structure.

These inputs help the graphics team represent the actual installation. For example, an AHU with a heating coil and economiser needs a different screen from a cooling-only unit. Equipment names should match across drawings, the database and the operator interface.

Reviewing BMS graphics before handover

Check each screen against the approved controls documents. Confirm sensor locations, equipment tags, units, point bindings and navigation links. Test that fan animation follows the intended status point and that alarm indicators reflect the correct conditions.

Unavailable or unreliable data should have a distinct indication so an operator can recognise it. Where commands are included, verify permissions and command behaviour. Review the finished screens with the facility team on the display they will use.
