weEMS
Das Energiemanagementsystem weEMS bringt alle Energie- und Verbrauchsdaten eines Gebäudes an einem Ort zusammen — Strom, Wärme, Wasser und Mobilität, live erfasst und zentral steuerbar. Verbräuche werden automatisiert abgerechnet, inklusive Mieterstrom- und Nebenkostenabrechnung, und liefern verlässliche, jederzeit exportierbare Daten für ESG-Reporting.
Im Ergebnis heißt das weniger manueller Aufwand, niedrigere Betriebskosten und zusätzliche Erträge durch Mieterstrom.
