# Master Thesis - Realtime Evaluation of Occupant Building Interactions using Modelica Building Models 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. 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 called JuControl, building occupants can interact bidirectionally with the building systems to e.g. determine heating schedules and improve indoor air quality. As part of our team, you will contribute to improvements in occupant behavior within buildings by deploying building models to estimate and optimize energy use in offices, as well as support better indoor air quality in a real-world setting. ## Your Job - Refine available building models (digital twins) in Modelica and export as FMU - Set up the building models online to be run on demand - Extend JuControl app to exchange data with the online building models and trigger model execution - Extend JuControl app to present the data to the user in an understandable way - Test and report on the effectiveness of the interventions on building users ## Your Profile - Ongoing masters degree studies in computer science, engineering, or other closely related field - Excellent programming skills in Python - Familiarity with web development (including backend frameworks like Django / FastAPI, and frontend frameworks like ReactJS) - Knowledge of mathematical modeling of energy / building systems - Good analytical skills, initiative, and self motivation - Good command of the English language - Excellent teamwork and communication skills ## Our Benefits for You We work on the very latest issues that impact our society and are offering you the chance to actively help in shaping the change!
