Sustainability at Hotel Sonne

The Sonne has stood for lived hospitality for centuries. As a historically grown establishment, we do not see sustainability as a trend, but as an integral part of our self-image.
Our unique location directly on Lake Zurich obliges us in a special way: we act with foresight so that future generations can also enjoy this extraordinary backdrop in all its beauty. Our commitment is therefore based on a responsible approach to people, nature, and cultural heritage – and is reflected in all areas of our daily operations.

Resource conservation in day-to-day operations

With respect for the environment and resources, we consistently focus on using energy and water responsibly and efficiently. Our infrastructure includes resource-saving technologies, modern control systems, and regular training for our team – always in the spirit of conscious and sustainable consumption.

Social commitment and local affinity

Our hotel is open to all people – regardless of origin, lifestyle, or social background. Our long-standing partnerships with local producers, suppliers, and creative artists are based on fairness, transparency, and mutual trust. Through this closeness, we strengthen regional value creation – whether in the tourism or retail sectors, or as a reliable employer.

Our team – live our values, shape the future
