Sustainability – we love green

We take responsibility for sustainability every day. Conservation of resources, social commitment and respectful conduct towards partners and staff mean a lot to us. Therefore we are carbon-neutral in heating, cooling and in producing warm water. The “Österreichisches Umweltzeichen für Tourismus” (Austrian Ecolabel), the European Ecolabel, our solar plant (which is the biggest in Viennese hotel industry) and our partnerships with charity organisations are clear signs of our commitment. Spending your vacation with us will give you a clear conscience.

Energy – less is more

Our electricity exclusively comes from renewable resources. Also, we produce more than half of your energy for water heating by our own solar plant. Since 2021, we have a groundwater heat pump. Thus, Der Wilhelmshof is now carbon-neutral in heating, cooling and procuding warm water – we do not use any fossil fuels. Consequently, we could further decrease our energy consumption by 75%. Our house is excellently insulated (apart from the beautiful, structured façade which makes insulation impossible), and has three-paned insulation windows. Hotel rooms, aisles and staircases are equipped with energy-saving bulbs or LED lighting. Owing to this, Wilhelmshof is one of Vienna’s most engery-efficient hotels.

Sustainable delight

We prefer local and organic produce. Our assortment of teas come from Sonnentor, our juices from Höllinger and our choice of coffee specialities are from Hornig (organic and fair trade). You will find products such as “Die gute Schokolade” (which supports the reforestation of the rain forest) and Tres-Hombres rum (shipped without CO2 emission by sailing boat). We don’t want to stop our environmental commitment when it comes to culinary treats and thus we support the Initiative United against waste and produce hardly any waste.

Excellence in sustainability

We act in common: for hospitality

The Wilhelmshof is a family-run business that thrives on the friendly atmosphere of the people involved. We encourage both, our guests as well as our staff: just be just yourself. This creates friendship and partnership between our guests, staff and the enterprise. It is our conviction that this is the only way to provide personal and perfect service.

We help!

We are fortunate to live in Europe and to run a successful business. As this makes us grateful, we love to help less fortunate people. Thus, we support some Austrian and world-wide projects with our donation budget and charity events. This comprises “Nachbar in Not” (neighbour in need), World Vision as well as very individual support and integration projects.

Sleep Green Hotels

Charles Darwin once said: „Anything against nature will not abide for any length of time” and we take this to heart. Sleep Green Hotels stand for the genuine, for persistency and sustainability. Sleep Green Hotels are a co-operation of individual hotels united by one vision: a sensitive and considerate handling with precious, natural resources and a holistic approach with new ideas that won’t demand things from our environment that we won’t be able to return.
