Innovation leader with many years of expertise

We are your energy optimizers!

At Berg, we are more than the sum of our employees. We are a dedicated and diverse team that works together with passion to improve energy efficiency at companies in an economic and ecological way.

Our energy management solution Efficio and the load and charging management system Optimo help you to record all media – such as gas, water, electricity, cooling, compressed air, etc. – taking into account the process parameters – temperature, pressure, humidity, quantities and much more.

If Germany wants to effectively reduce its carbon dioxide emissions and meet internationally agreed climate targets, it must restructure its energy system to make it sustainable and fit for the future. With our optimized energy and load management solutions, companies can operate in a climate-neutral and cost-effective manner. When it comes to funding opportunities, we provide comprehensive advice, work with our clients to tap into financing potential and find funding approaches.

As an agile and reliable innovation leader with many years of expertise in dynamic energy markets, we have earned top references in all sectors of industry and in public institutions and, as “watt watchers”, make our contribution to greater grid stabilization.

Since 2019, Berg has been a subsidiary of VIVAVIS AG, which also includes the other expert companies AMW GmbH, Caigos GmbH, and eoda GmbH. VIVAVIS bundles expertise and portfolios when it comes to infrastructure and infrastructure-related IoT topics. Here, solutions are developed that help decode complex processes and translate them into intuitive applications. We are all united by the vision of actively shaping the future of digital infrastructure, driving digitization forward, and mastering big data. With our technologies and services under the VIVAVIS umbrella, our customers can open up new, sustainable business areas.

Our systems have a modular structure and can also be customized to your individual needs.

This gives you a tailor-made solution for professional energy optimization.
