Regenerative supply. Securing the future.
Nationwide representation – 100% medium-sized business. 100% family-owned.
As one of the leading medium-sized companies in technical building equipment, we stand for modern technologies, the highest quality, and reliable implementation. Our solutions ensure a sustainable energy supply – economical, future-oriented, and value-oriented.
We deliver what powers buildings – efficiently and everywhere.
Whether in exclusive residential areas, medical facilities, or modern office buildings, we create reliable energy supplies and intelligent building technology. Our spectrum ranges from large-scale projects with a high degree of automation to sustainable power generation using solar technology and future-proof heating solutions with heat pumps. No matter how large, complex, or individual. We develop tailor-made solutions adapted to the wishes and requirements of our customers. Sector coupling plays a central role for us and our customers: we intelligently network electricity, heat, and mobility to create a sustainable energy system for your buildings. With photovoltaics, heat pump technology, storage systems, and charging infrastructure, we ensure stable energy flows, reduce operating costs sustainably, and use resources as efficiently as possible.
We take building equipment to the next level.
With technical excellence, economic thinking, and a clear commitment to quality, we implement solutions that have a future. We strive for perfection in execution, technical reliability, and service.
Our projects demonstrate what we can achieve:
- Electrical engineering for a major cultural project: Creation of the complete infrastructure, including building systems and network technology, at the National Theater in Mannheim.
- Solar technology with architectural appeal: invisible energy generation through integrated solar roof tiles on an angled roof in Berlin.
- Green roof with system: 1,750 m² of roof space sustainably sealed, greened, and drained in the “Kirschgärten” terraced housing estate in Potsdam.
- Electrical engineering for modern working environments: Security, communication, and energy infrastructure covering 4,000 m² in an administration building with laboratory in Bielefeld.
- Smartly networked and energy-efficient: 151 residential units equipped with KNX, photovoltaics, e-mobility connection, and network technology in the “Le Flair” residential quarter in Düsseldorf.
