Challenge
The automation of the Mühlbacherhof guesthouse required the seamless integration of heating, cooling, ventilation, lighting, access and energy management. The aim was to achieve efficient, conflict-free interaction between all systems.
The 90 kWp PV system was optimized so that the heating elements, heat pump and charging stations were dynamically controlled and energy flows were prioritized - especially in conjunction with the 110 kW DC charging system.
Hotel operations benefited from automatic adaptation to occupancy, including intelligent lighting, temperature and shading control. Seasonal fluctuations were taken into account in order to optimize energy consumption.
Real-time error messages for heating, cooling and charging stations ensured smooth operation. An efficient access control system with integrated camera monitoring was also implemented.
Thanks to intelligent control strategies, a fully automated, energy-efficient system was created that increases guest comfort and reduces operating costs.
Solution
Various intelligent solutions were implemented to meet the complex requirements for energy efficiency, automation and comfort in the hotel operations at Pension Mühlbacherhof. The central building automation was realized with Loxone, whereby heating, ventilation, cooling, lighting and access systems are networked and controlled via a uniform logic. An intelligent control system ensures demand-based control in real time, while guests and employees benefit from intuitive operation via buttons, apps or automatic functions.Energy management was optimized by a smart grid control system. The 90 kWp PV system has been fully integrated so that the electricity generated is used specifically for heating elements, heat pumps and charging stations. A load-dependent control system automatically regulates consumers up or down to avoid grid load peaks. The individual room control is linked to presence sensors. A 1-button reader detects whether a guest is present and automatically adjusts the room temperature, lighting and shading. Energy-saving mode is activated when the guest is absent, while a comfort mode starts immediately when the room is entered. Automatic shading reduces energy consumption and prevents overheating.
The heating control system adapts flexibly to seasonal operation. In winter, the focus is on heating the rooms, lobby and restaurant, while ventilation and cooling are prioritized in summer. In the off-season, only used areas are heated or air-conditioned in order to save energy. The charging infrastructure for electric vehicles has also been intelligently managed. The 110 kW DC supercharger is given priority for surplus PV power by automatically switching off consumers that are not required. Prioritization is dynamic, so that the heating output is reduced when an electric vehicle is charging. A monitoring system detects potential problems and reports errors directly to the operator.
For maximum safety, a central monitoring system has been implemented that monitors critical hotel areas in real time. Cooling and freezing cells trigger alarms if temperatures are too high, faults in the heating system or water heating are automatically forwarded to technicians, and superchargers and inverters are permanently monitored. The camera system is integrated directly into Loxone and improves security control.
The hotel and campsite control systems were also optimized. Access control for hotel and campsite areas was implemented via Loxone, as was music control in the bar, breakfast room and youth room with various audio streams. The ventilation and lighting control for common areas as well as the outdoor lighting were also automated to maximize energy savings.
These measures have created a state-of-the-art, energy-efficient and fully automated hotel operating system. The self-consumption of the PV system was maximized through intelligent load distribution, guest comfort was increased through automated room control and operational safety was optimized through fault monitoring. The system offers a sustainable and future-proof solution for the hotel and campsite while significantly reducing energy costs.
We chose Loxone for this project because it offers a holistic, intelligent control solution that perfectly combines energy efficiency, comfort and automation. With Loxone, we were able to seamlessly network and optimally control all systems - from heating and room control to charging management and access control - in order to make the operation of the Pension Mühlbacherhof as efficient and future-proof as possible.
