Master Thesis - Hybrid ML + LLM-based Fault Detection and Explainability for Smart Building IoT Systems

At the Institute of Climate and Energy Systems - Energy Systems Engineering (ICE-1), we develop advanced models and algorithms for the simulation and optimization of integrated multi-energy systems. Within the Living Lab Energy Campus (LLEC) project, large office buildings are equipped with many IoT devices, typically 5-10 devices per office room. These devices transmit real-time data such as the opening state of windows, doors as well as room air quality and luminance measurements to a cloud infrastructure. Additionally, through a user-facing energy dashboard with a desk booking system, building occupants can interact bidirectionally with the building systems. These occupant-building interactions are the basis for several avenues of research including the intelligent operation of heating and shading systems. As part of our team, you will contribute to the smooth and reliable operation of the building systems through implementation of online fault detection and diagnosis, and subsequent communication of the results to real users in a real-world setting.

Your Job

• Installation and configuration of available occupancy detection sensors (e.g. PIR sensors, PQI meters, infrared camera, etc.)
• Setup of suitable experimental plan for testing the occupancy estimation approaches
• Analysis of characteristics of the various approaches in terms of ease of setup, cost, data quality, suitability for different end-uses, etc.
• Analysis of combinations of approaches in terms of detection accuracy and reliability

Your Profile

• Ongoing masters degree studies in computer science, data science, engineering, machine-learning, or other closely related field
• Good knowledge of programming in Python
• Good knowledge of machine-learning and artificial intelligence
• Knowledge of fault detection in sensor data
• Good analytical skills, initiative, and self motivation
• Good command of the English language
• Excellent teamwork and communication skills
