Located in Vienna’s 15th district, Boutiquehotel Stadthalle has earned global recognition for its sustainability revolution. It became the world’s first city hotel with a zero-energy balance, generating as much energy as it uses, while fully aligning with the United Nations’ Sustainable Development Goals (SDGs).
Zero-Energy Innovation
- Achieved zero-energy balance by combining a passive-house extension with 93 m² of photovoltaic panels and a 130 m² solar thermal system.
- Uses geothermal heat-pump technology with groundwater cooling/heating and controlled ventilation.
- Eliminated minibars in rooms, reducing CO₂ emissions by over 21 tonnes yearly.
Sustainable Hospitality & SDG Work
- Since 2020, every room is dedicated to one of the 17 SDGs, featuring upcycled furniture by social enterprise Gabarage, chosen to blend design, education, and function.
- Holds both the Austrian and EU Ecolabels, and has won multiple environmental awards, such as the Austrian Climate Protection and Vienna Environmental Prizes ( you can read about how the idea of the hotel began here).
- Incorporates cradle-to-cradle furnishings, microplastic-free toiletries, LED lighting, eco-showerheads (cutting water use by ~35%), and greywater recycling.
- Offers a 10% “Green Bonus” discount to guests who arrive by bike or train, and even grows its own lavender and keeps bees to support biodiversity and local honey production.
Guest Experience & Community Impact
- Features a lavender roof and courtyard garden, tempting guests with organic honey and soothing greenery amidst city life.
- Uses only organic, local breakfast fare, with vegan and vegetarian options; sources coffee via sail to reduce transport emissions.
