Germany's and Europe's leading real-estate service provider Apleona is investing in a self-learning technology based on artificial intelligence (AI) in the field of energy and CO2 optimization. The company, which specializes in integrated facility and real-estate management, has therefore acquired an interest in Bonn-based green tech company Recogizer. Recogizer uses its "energyControl" AI system to create digital twins of buildings and their technical facilities, enabling fully automated predictive control of heating, ventilation and air conditioning technology in real time, all while predicting and taking into account the environmental conditions and usage parameters of each building. This achieves average energy savings of 20% to 30% and a comparatively large reduction in CO2 depending on the energy supply situation. At the same time, this smart system ensures a comfortable and ideal room climate for the user; one that is not affected by short-term changes in weather, the way the building is used or how much time the user spends there.
