Sustainable energy concepts only make sense, if the energy required for the building´s operation or the production has been minimized. The utilization of renewable energies will significantly reduce the energy costs and contribute to a reduced dependence on non-renewable energy sources. Precondition for solar or geothermal energy usage, is the lowest possible energy demand for the building`s operation or for the production of goods.
Renewable energy utilization is also becoming increasingly important due to constant amendments to the “EEG Act” (Renewable Energy Act). The requirements arising by the “EEG Act” can be met through the intelligent operation and the integration of renewable energy usage in energy concepts. Renewable energy utilization is a necessary foundation for the future energy-neutral supply.
