Lighthouse Tagger
Sector-coupled energy optimization and intelligent control for urban districts
The project expands an existing heat optimization system to include cooling, shading, and e-mobility. Predictive control algorithms for cooling and electricity are being developed to optimally accommodate individual comfort zones. A sector-coupled energy management system with intelligent controllers, sensors, and building-wide optimization is being implemented at the Tagger site. The app is being further developed with regard to usability, visualization, and user participation, and is being enhanced with energy literacy, incentive systems, and gamification. AI-supported personas enable inclusive, needs-based development of measures. The system increases efficiency, reduces energy consumption, and makes sustainable behavior visible and tangible in everyday life.
This project is funded by the Climate and Energy Fund (Klien) financed. The funding process is handled by the Austrian Research Promotion Agency (FFG).

THE INNOVATIONS
Here are 5 key innovation points that clearly and understandably summarize the core of the project:
Cross-sector real-time optimization
Holistic control of heat, cold, electricity, shading and e-mobility – integrated for the first time in a system with energy optimization and user flexibility.
Digital Twin & Predictive Control
Semi-physical digital twin links building data, plant conditions and user profiles for simulation-based, robust decisions and continuous efficiency improvement.
Dynamic local pricing
The system reacts to the current situation (e.g., high solar power or high grid load) and thus helps to use energy when it is cheap.
AI-powered personas & personalized interaction
A combination of real-world behavioral data and AI models for targeted user communication. This provides relevant feedback that strengthens energy awareness and increases comfort.
Retrofittable, modular architecture
Wireless, building-protecting sensors and actuators enable easy scaling to existing buildings and cross-building applications – ideal for real-world neighborhoods.
