Sustainability as a matter of principle: Vision becomes reality

A large portion of CO2 emissions worldwide come from energy produced from fossil fuels. CO2 emissions can be reduced with increased use of renewable energy. Our products and solutions actively promote the continuous production of energy from renewable resources and the direct consumption of this energy. A clean environment is essential for us!

Solar-Log® headquarters in Geislingen-Binsdorf is a representation of our commitment to the environment. The energy used in the building for daily work comes from renewable sources. The building is heated by hidden energy from and ice storage system. Two heat pumps first extract energy from the water in the storage tanks and then use this energy from the phase change (between liquid water and frozen ice), forming a large ice cube in the storage tank at the end of the heating phase. This cooling potential is used to keep the building cool during hot summer months.
