Cleantech / Climate Tech

1KOMMA5° wurde im Juli 2021 mit dem Ziel gegründet, alle Gebäude CO2 neutral zu machen. Dies erfolgt durch den Einsatz von Photovoltaik, Wärmepumpe und Ladeinfrastruktur in Verbindung mit einer intelligenten und individuellen Steuerung aller Systeme basierend auf künstlicher Intelligenz, um den besonders günstigen Preiszonen von Sonne und Wind direkt an der Strombörse zu folgen. Nach drei Jahren hat das Unternehmen bereits 100.000 Kunden bedient und gilt damit laut EUPD Studie seit 2024 als europäischer Marktführer. Technologisches Herzstück ist die Software Plattform “Heartbeat AI”. Sie verbindet Wärmepumpe, Ladesäulen und Strombatterien direkt mit der Strombörse und steuert jedes einzelne Systeme nach individuellen Fahrplänen durch künstliche Intelligenz. So wird individuell immer der jeweils günstigste und sauberste Strom bereitgestellt, ob vom eigenen Dach oder vom Energiemarkt. Zurzeit betreibt 1KOMMA5° über 75 Standorte und Meisterbetriebe mit rund 2.200 Mitarbeitenden von Europa bis Australien. Zusätzlich arbeitet 1KOMMA5° kontinuierlich an der Weiterentwicklung der Heartbeat AI 🤖 Platform hierzu arbeiten allein am Entwicklungsstandort in Berlin über 200 Entwicklerinnen und Entwickler. Bereits 30% der mit Heartbeat AI verbundenen Haushalte erwirtschaften durch den Verkauf von Strom in Hochpreisphasen mehr Erlöse als sie Stromkosten. Insgesamt steuert das System nach kurzer Zeit bereits über 40.000 Energiesysteme.
