The OHA Druck print shop in Traun relies on a sustainable energy supply with a modern rooftop photovoltaic system. With an output of 60.48 kWp, the system generates around 63,500 kWh of clean electricity per year. This means that a significant proportion of the energy requirements can be covered directly on site – a decisive advantage in an energy-intensive industry such as print production. In addition, the project saves around 24 tons of CO₂ every year and thus actively contributes to reducing the ecological footprint.
