Energy efficiency defines the optimal use of energy to achieve a desired benefit, for example the supply of heating or lighting. The smaller the energy consumption for the benefit to be brought about, the more energy-efficient a technology or product is. In addition to energy efficiency, reducing the absolute energy demand is also crucial for the energy turnaround. As a rule, the conversion and use of energy always results in the generation of pollutants, especially when fossil fuels are used. The German government therefore plans to reduce electricity consumption by 25 percent by 2050, based on data from 2008. Buildings account for almost 35 percent of total final energy consumption in Germany. Owners and operators should make building operation more efficient not only to save costs, but also to reduce the impact on the environment. Energy efficiency often goes hand in hand with a higher degree of automation, which also benefits the comfort of the users. With the aedifion cloud platform, you can reduce your building's energy consumption systematically and AI-based. The Energy Bundle gives you all the tools you need to implement energy management according to ISO 50001.
