20 Bregenz Ground water cooling in plant 4 The favourable conditions at plant 4 have made it possible to set up an inter- nal, closed-circuit groundwater cooling system for our production facilities and rooms. This system does not impact either the quality or the quantity of the ground water. Gaissau Harnessing solar power for hot water The water used for the coating process at plant 6 is heated by 457 m 2 of high-performance solar collectors, which use sunlight to heat water in an environmentally-friendly way. Höchst Electricity for the e-fleet Together, the photovoltaic systems at our two plants in Höchst and one in Bregenz cover a total surface area of around 2000 m 2 . These systems have a total output of 300 kWp, which provides electricity for various uses including the company’s fleet of electric vehicles. China Up on the roof Our largest photovoltaic system can be found in China and covers an area of 8240 m 2 – the equivalent of 660 car parking spaces. The system output amounts to 1400 kWp. Dornbirn Out with gas – in with district heating Plants 7 and 8 in Dornbirn are connected to the local district heating net- work. This means that gas is no longer required for heating in these plants. The gas boilers have been kept in situ for emergency heating. Any excess heat is fed back into the grid – thus reducing our cooling costs. Annual savings from ground water cooling 20,000 m 3 of water Vorarlberg Hurray for hydropower! Compared to using the local supplier’s standard electricity generation mix, we have saved around 34,600 tonnes of CO 2 since 2018 by using 100 % hydropower from Austrian hydroelectric power plants. That equates to: Vienna 59,000 kWh of electricity Climate protection and emissions 26.800 x NYC
