Sleeves up for the climate. Projects and measures at a glance In recent years, Schöck has identified a wealth of opportunities for systematically reducing energy consumption and greenhouse gas emissions (GHG emissions) and increasing the generation and use of energy from renewable sources. In the future, the intention is to continuously develop the fields and measures in order to maximise the positive impact on the overall energy balance. Here is an overview of the most important measures and their effects. Measure 1: Expansion of renewable energies: Photovoltaics at Schöck Schöck is investing in the expansion of renewable energies at all locations. The company has been investing in its own photovoltaic systems for years, and will continue to expand them in the future. The goal is to achieve a total photovoltaic system capacity of 1.1 MWp across all the German sites. Currently, the headquarter in Baden-Baden has the most sophisticated photovoltaic infrastructure, a fact also reflected in the electricity output generated. Capacities are also being continuously expanded at the two other German sites in Halle and Essen. Photovoltaic systems are also planned for the international production sites in the coming years in order to increase in-house electricity generation across the entire group. Measure 2: Heat recovery from production processes The production of the Isokorb® requires tension bars made of reinforcement steel and stainless steel that are manufactured on welding machines. Until 2020, the welding fumes produced were extracted by three standalone systems without utilising the energy. To make the system as energy efficient as possible, Schöck invested in a centrally controlled, compact welding fume extraction system. This investment was wholly justified because it uses much less power. A further advantage is the use of the welding fumes for heat recovery. This has significantly reduced the need for thermal energy. Since the new system has been in operation, no additional natural gas is needed to heat the air in the recuperator. In total, the introduction of the new system in 2020 resulted in an energy saving of around 500 MWh a reduction in greenhouse gas emissions equivalent to 188 tonnes of CO2 which has been continued in the following years. Other consumption-reducing measures include the reduction in pressure in the compressed air system at the Baden-Baden plant, which has saved 62 MWh, and heat recovered from compressed air generation at the Halle plant, which enabled a reduction in energy demand of 24 MWh. New outdoor LED lighting reduced electricity demand by a further 10 MWh. Measure 3: Use of electricity from renewable energy sources The entire electricity demand of the Schöck Group is to be gradually covered by renewable energies. To this end, Schöck is investing among other things in a solar park in Andalusia, Spain, near Jerez de la Frontera. The planned total output here is 57 MWp in the final expansion stage, the calculated yield of the total plant is 2,000 VBh/kWp. The exact level of Schöck's participation is still in discussion. Measure 4: Sustainable business buildings Schöck not only wants to contribute to the energy efficiency of buildings with its products, but also to build energy-efficient buildings itself. Therefore, new company buildings or building extensions are built in a resource-conserving and sustainable manner. Existing buildings are constantly modernised to reflect the latest environmental standards. New buildings in Baden-Baden and Halle In 2018, two production halls were built in Baden-Baden and Essen, whose energy consumption is 20% below the standard set by the Energy Saving Regulation valid at the time. Highest sustainability standard at the headquarters In 2019, the headquarters in Baden-Baden was expanded with a new 5,587 m² building. This was constructed to the passive house standard. Thanks to appropriate insulation and internal heat sources, the energy requirement of the new building is 12 kWh/ m² per year, which is lower than the passive house standard of 56 Company Sustainability management Fields of activity GRI content index
