Smart IoT cuts energy use and emissions at mountain resort


EnOcean is bringing smart building automation to a high- end mountain resort in China through the use of IoT technolody. This allows energy to be used efficiently and CO2 emissions to be reduced, while promoting the well- being of people through sustainable activity


T


he Dachangping Leisure Resort Hotel, located on Dazhangping Mountain in Anji (China), covers 10,100 square metres of land and 4,800 square metres of buildings. The hotel includes dining, sports,


conference, and accommodation facilities. Surrounded by mountains and bamboo forests, it offers guests a unique escape from the city. Key requirements for this sustainable project


were energy and carbon reduction, as the Anji region plays an important role in China’s dual- carbon strategy. At the same time, it needs to offer a high level of guest comfort.


Key requirements included:


• Smart guest room control for a better stay • Automatic lighting and HVAC based on room occupancy


• Power-down of non-essential equipment when guests leave


• System interaction using data from a weather station


• Remote maintenance capabilities due to the mountain location


Hybrid control architecture


The solution INTERFUEHLER Automation Equipment (Shanghai) Co., Ltd. developed combines wireless flexibility with wired reliability. All devices below the ceiling use wireless, battery-free EnOcean technology. Devices above the ceiling connect via bus systems. Each light, air vent, and


other device has a unique address for individual control. This setup allows precise scene creation and enhances comfort.


Designers placed beds near the windows so guests can enjoy stunning mountain and bamboo forest views from bed. Guests can open the curtains by pressing a button – directly from the bed. Scene and HVAC panels are placed at the bedside. Temperature control is based on reading closer to the guest, ensuring optimal comfort.


Integrated systems for energy efficiency


All systems are interconnected to reduce energy use without compromising comfort. For example, when a room is unoccupied, lights dim and air conditioning flow decreases. If the sensors detect no movement for a longer period, the lights turn off. Outdoor brightness data adjusts indoor lighting and HVAC settings. Rooms that remain vacant will have shades drawn, lights off, and HVAC shut down.


Scenes and zones quality


Scene modes and zone control are used throughout the hotel. One-touch scenes simplify use for guests and create a welcoming atmosphere. For staff, zone control improves management efficiency. From public spaces like the lobby and restaurant to private rooms and meeting areas, all zones have scene control and device-level adjustments. Each device can be configured individually. The wireless


setup also allows easy reconfiguration for future repurposing of the spaces.


Visual control and remote access


Guests and staff can use both local EnOcean panels and remote smart terminals. The system supports web access and apps for Windows, iOS, and Android. It allows control of lights, brightness, color temperature, scenes, air conditioning temperature, and airflow. Remote maintenance is also supported, ensuring fast response in case of issues.


Benefits of the EnOcean-Based Solution for sustainability and


well-being The project fulfils the high requirements for smart building automation, sustainability and comfort. It reduces energy consumption and CO2 emissions and increases people’s well-being. Battery-free, wireless sensors and IoT technology made it possible.
