Nestled in the Breitnau region of the upper Black Forest in Germany lies a 500-year-old hotel that is not your average accommodation option. While the classic Bavarian structure may seem like a traditional space for visitors to explore the history and natural beauty of the region, Hofgut Sternen is actually a marvel of energy self-sufficiency.
Owned by the Drubba family, the hotel has a rich history of utilizing hydropower to operate its facilities. Originally relying on water mills along the gorge rivers, the property has now transitioned to a more modern and sustainable system. In 2010, an interconnected system was designed to power and heat the entire property, including guest rooms, a glassblowing studio, and even the region’s largest cuckoo clock.
Hidden behind the scenes of the hotel is a sophisticated network of pipes, power stations, and heat pumps that work together to generate electricity and heat for the property. The hotel pumps its wastewater to a nearby treatment plant, where the water is treated and then returned to the hotel for energy production. This process not only powers the hotel but also cools the water to an appropriate temperature for the environment.
During the winter months, a wood chip power plant fueled by the remnants of the woodcutting industry fills in the energy gaps. Additionally, a spring water catchment system is utilized to pre-cool drinks and air-condition studios on the property. The building itself plays a role in the energy network, with exhaust air from various operations being collected and converted into electricity or heat.
The hotel’s commitment to sustainability extends to its water usage as well. All clean water for the bathrooms and kitchen is sourced from a nearby spring and warmed by the same water used for heating the rooms. This closed-loop system ensures that resources are efficiently utilized and recycled.
While the intricate system of energy production and conservation may seem complex, owner Thomas Drubba emphasizes that each step has been carefully designed for maximum efficiency. The hotel not only provides a sustainable place for guests to stay but also contributes to the protection of the surrounding Black Forest, staying true to its renewable roots.
In conclusion, Hofgut Sternen serves as a model for sustainable energy practices in the hospitality industry. By harnessing the power of water, heat, and other natural resources, the 500-year-old hotel has achieved energy self-sufficiency while minimizing its environmental impact. As travelers seek eco-friendly accommodation options, establishments like Hofgut Sternen set a high standard for sustainability and responsible tourism.
