Challenges
Hotel Obermaier is a historic, family-owned hotel in Munich, operated by the Obermaier family since 1863. The hotel's 53 rooms in its historic building relied on manual heating controls, resulting in unnecessary energy consumption when rooms were unoccupied. Guests often turned the heating to the maximum, and after their departure, the room continued to heat up for hours. In some cases, windows were left open, resulting in significant unnecessary energy waste. Looking to improve efficiency without compromising guest comfort or the character of the historic property, the hotel needed a smart retrofit solution that could be installed quickly, integrate with the existing heating system, and minimize structural intervention.
Solution
By integrating the better.energy platform with the existing property management system (PMS) and equipping the hotel's rooms with 53 Vicki LoRaWAN® Smart Radiator Thermostats, Hotel Obermaier transformed its conventional heating system into a smart one. The wireless retrofit was completed in just two days by the hotel manager himself, without structural modifications or disruption to hotel operations, making it ideally suited for the historic building. Through automated occupancy-based heating, rooms are heated only when needed, while open-window detection prevents unnecessary energy losses. Thanks to the better.energy platform, room occupancy and heating are now synchronized in real time – when a guest checks out, the temperature is remotely lowered by the Vicki Smart Radiator Thermostat. Conversely, when a guest checks in, the system preheats the room, so staff doesn’t need to intervene manually anymore. Additionally, the manual rotary control of the device allows guests to adjust the temperature to their comfort level, while letting the hotel management team set a maximum and minimum level to limit energy waste. At the same time, the device allows setting a precise target temperature in public areas, not allowing guests to override it via the “Child lock” functionality. Since the installation, the hotel has significantly reduced overheating, ensuring a comfortable indoor climate for guests while improving energy efficiency. Combined with the better.energy platform, MClimate’s devices help reduce staff workload, maintenance requirements, and overall energy costs, all without requiring structural renovations or disrupting hotel operations.
