Combine AHU differential pressure telemetry with IFC equipment attributes to predict filter replacement intervals. Formulate service alerts with manufacturer filter specifications before airflow degrades.
Indoor Air Quality Specialist
Ingest AHU filter differential pressure telemetry feeds.
Query the building IFC model for air handling unit specifications and filter sizes.
Detect pressure drop thresholds exceeding manufacturer service recommendations.
Dispatch structured filter replacement tickets into the facility work-order queue.
Maintenance supervisor console with filter pressure gauges, telemetry timeline graphs, and a work-order dispatch panel.
Simulate AHU telemetry against open-source BIM models containing MEP air handling units from IfcOpenShell repositories. Starter examples below are synthetic. They are not downloaded records.
IfcOpenShell Extracts AHU equipment metadata and filter specifications from IfcBuildingElementProxy and IfcPropertySet instances.
mastra-ai, ifcopenshell, fastapi. Mastra AI provides resilient workflow orchestration to trigger filter replacement alerts based on incoming differential pressure telemetry events. Local or hosted LLM to translate airflow telemetry anomalies into standard maintenance instructions.
Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.
Correlates raw sensor telemetry with corresponding IFC AHU element GUIDs.
Triggers preventive service requests when differential pressure exceeds 200 Pa.
Outputs work orders populated with IFC-derived equipment tags and filter specifications.
