Due to its location, the nature aspect was an integral part of the founding philosophy of the Wiesen festivals and still contributes in no small part to Wiesen's attractiveness and distinctiveness. In order to reduce the ecological footprint, numerous steps were taken early on to minimize the impact on the environment.
An important point of our eco-concept, which was implemented relatively early on, is the reduction of water consumption. When we built our new visitor toilets in 1997, we created a 54,000-liter rainwater collection basin under the sanitary building. The rainwater collected in it is used for toilet flushing and lawn irrigation. We also optimize the irrigation of our green areas with the help of controllers, timers and soil moisture measurements.
In order to save energy and reduce CO2 emissions, a photovoltaic system with an output of 10kWpeak was installed on the green roof of the catering hall in 2013. Since commissioning (as of 08.09.2015, 15:00), 20,845 kWh have been generated, saving the environment over 12 tons of CO2. Although this cannot cover the high electricity consumption during the event days, the existing system supports the pre- and post-event phases.
The second acquisition that makes use of solar energy is our thermal solar system. Four pieces of vacuum tube collectors with a capacity of 12 kW are in operation for the preparation of hot water. All the hot water for the kitchen, washing machine, hand basin, showers and cup washing system is heated in this way.
The same system that helps us manage our water consumption sparingly also controls our lighting, 90% of which is made up of energy-efficient light sources (LEDs and energy-saving lamps).
Green roofsNative plantsbloom on a roof area of approximately 1,500 m2, providing a natural habitat for insects and small creatures. The planted roofs dampen noise, keep the buildings cool, avoid the use of air conditioning and save further CO2 emissions.
Waste separation and waste avoidance
Since the early 80s, we have housed a few very special relics in the backstage area: four discarded railroad cars were converted into artists' dressing rooms. After we had used the various nostalgic-looking ÖBB sidecars for years with their original furnishings, they were given new interiors a few years ago. Externally, however, they have lost none of their charm.
Measure, Understand, Improve
In order to save energy and resources, you have to analyze and understand beforehand where exactly energy is consumed. With the EE Music IG Tools(https://eemusic.ig-tools.com), we have a CO2 calculator at hand that was specifically designed for venues and open air events. It helps us measure and understand our energy consumption and compare our energy efficiency to other festivals across Europe. This allows us to develop effective energy management strategies. In addition to energy consumption, factors such as water, waste and visitor travel are also taken into account.
