Those who are entrepreneurially active in a particular region for a long time have a particular responsibility towards it. We take this responsibility very seriously and always take care to act with it in mind.

Using renewable energies to protect the environment

Having built one of the region’s largest privately held solar installations, the "Gisinger Solarpark", underlines our lasting commitment for the environment. It generates around 250,000 kWh of ecofriendly energy each year, saving ca. 210 tons of CO2 emissions.

Many of our properties are equipped with state-of-the-art solar installations for hot water production and other pioneering energy concepts.
