Water and energy savings at BoutiqueHotel Stadthalle


In 2002, Michaela Reitterer bought the hotel ‘Zur Stadthalle’ and decided to consider ‘environmental awareness’ as the main vision of the company. Respect for nature and its resources is one of the main pillars of the company’s activities as well as guaranteeing relaxation in a unique atmosphere.

During the years, the hotel was restructured several times with the main aim of increasing the level of ecological sustainability of the structure, thus achieving the title of the world’s first zero-energy balance hotel in urban areas.


Boutiquehotel Stadthalle saves up to:

   21,024 kg CO2/year

   62.000 kWh/person/year (passive house)

   65L per guest * incl. laundry (passive house)


No heating needed (passive house)

Separation and recycle of 100% of waste produced


Boutiquehotel Stadthalle is an example of best practice implementing innovative ideas. It’s the first hotel in a city worldwide with a zero-energy balance. This implies that the amount of energy needed all over the year is produced by means of a ground water heat pump, 130 m² solar panels on the roof for warm water and 93m² solar panels for electricity.

The hotel only uses water from their own well to irrigate the plants and flowers in the garden.

The eco-shower heads include flow limiters which can  reduce water consumption by up to 35%, while the TVs are mostly on stand-by mode, with an extremely low energy consumption of just 1 watt. Furthermore, LED lights with low electricity consumption, 14 watts in total, are installed in the hotel.

Breakfast is served for 157 room being 100% organic with a big variety of regional delicacy especially for people with vegan lifestyle and food intolerances.

The garden is mainly dedicated to lavender cultivation and is a green oasis for four beehives.
