Boutique Hotel Stadthalle: World premiere with zero energy balance!
A milestone in sustainability in Vienna: The boutique hotel Stadthalle was awarded the Future Award. This honor takes place in the context of the handover of Michaela Reitterer's hotel to Cocoon Hotels and recognizes Reitterer's outstanding achievements in the area of environmentally friendly hotels. The hotel is the first city hotel in the world with a zero energy balance. This means that it sends a clear message not only internally but also externally: sustainability is the priority.
What makes the boutique hotel Stadthalle so special? The concept focuses on a variety of environmentally friendly technologies. This includes, among other things, a photovoltaic system on the roof that secures the energy supply, as well as the use of groundwater for cooling in summer and heat pumps for heating in winter. Such measures help minimize the ecological footprint and ensure guests have a pleasant stay.
Sustainability in focus
But that's not all. The hotel's courtyard and lavender facade actively promote biodiversity, while rainwater harvesting and consistent recycling are firmly integrated into the sustainability concept. Guests can look forward to a rich, regional and organic breakfast that meets the high standards of sustainability. All of this combines into one overarching goal: the boutique hotel not only wants to be a holiday destination, but also a climate goal.
What does the implementation of sustainable principles look like in practice? The hotel is based on the 17 Sustainable Development Goals (SDGs) and is also implementing them in the renovation of 16 rooms and the breakfast room. Guests can enjoy this urban retreat in the middle of Vienna, close to the Stadthalle and attractions such as Schönbrunn Palace. For an active stay, the hotel offers bicycles to explore the surrounding area.
A win for everyone
Another clever feature is the so-called “green bonus”: guests who arrive by bike or train receive a 10% discount on the room price. The hotel staff also ensures a warm atmosphere by taking care of breakfast and room cleaning, giving guests a completely worry-free experience.
The significance of the boutique hotel goes beyond its four walls. The sustainable approach is supported not only by the operators, but also by a wide range of tourism stakeholders, as the UN Tourism emphasizes. The balance between ecological, economic and socio-cultural factors plays a central role in the development of sustainable tourism.
In times when environmental awareness is becoming an increasingly important issue, the boutique hotel Stadthalle impressively shows that a successful hotel not only focuses on a high level of comfort, but also takes responsibility for our planet. The new chapter under the management of Cocoon Hotels promises to consistently continue on this path.
