Built Environment Predictive HVAC Anomaly Assistant with Google ADK

Commercial facilities require autonomous monitoring to cut energy waste and prevent system outages. Construct a multimodal predictive maintenance assistant using Google's Agent Development Kit (ADK) and Gemini models to process building acoustic recordings and sensor telemetry. Achieve 90%+ diagnostic accuracy on motor and compressor faults.

Delivery guide

How work is evaluated

Evaluation

Evaluates acoustic and sensor fault classification precision using Google ADK pipelines.

Datasets

Challenge datasets

Public datasets, plus the private datasets you have access to.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

Fault Classification Test

Accurately flags high-pitch grinding as bearing failure

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

Diagnostic Accuracy

Accuracy across multimodal fault test set • target: 0.92 • range: 0.85-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals
