The following information is from the last update, which took place in 2022 - 2023. If you are reading this notice, the provider has not updated its information since the last update and the information may be out of date.
The Co4 platform is the universal energy management solution for portfolio/property managers and energy service providers. Monitoring, optimization, reporting and billing are conveniently combined in a single, adaptable tool. Thanks to its modular approach and third-party open structure, the scalable cloud platform enables the unlocking of synergy potentials beyond the scope of proprietary systems. Co4 forms the usually missing link between existing building technology and the management tools used. Thanks to a manufacturer-independent platform solution and bi-directional communication, energy data, EV charging stations, systems and properties can not only be monitored and billed, but also optimally operated.
