Explainable AI for Chiller Fault-Detection Systems: Gaining Trust and Human Connect
Chillers are energy-intensive, prone-to-faults components used for space cooling in buildings. Data-driven Fault Detection and Diagnosis (DD-FDD) are widely used for chillers. However, field personnel are often not confident in DD-FDD mainly because no explanation is given for the results. EXplainable Artificial Intelligence (XAI) can help bridge this gap. We investigate XAI-FDD’s role in building trust in DD-FDD. We examine use-cases for XAI-FDD on a building in Singapore having 6 chillers.

Causal 1-D convolutional neural networks based chiller fault detection and diagnosis
Modern buildings are densely equipped with smart energy meters, which periodically generate a massive amount of time-series data yielding a few million data points every day. This data can be leveraged to discover the underlying load and infer their energy consumption patterns, inter-dependencies on environmental factors, and the building’s operational properties. Furthermore, it allows us to simultaneously identify anomalies present in the electricity consumption profiles, which is a big step towards saving energy and achieving global sustainability. However, to date, the lack of large-scale annotated energy consumption datasets hinders the ongoing research in anomaly detection. We contribute to this effort by releasing a carefully annotated version of a publicly available ASHRAE Great Energy Predictor III data set containing 1,413 smart electricity meter time series spanning over one year. In addition, we benchmark the performance of eight state-of-the-art anomaly detection methods on our dataset and compare their performance.
