Heating & cooling, photovoltaics, electromobility

We work with you to create customised climate-friendly solutions for large individual buildings, building projects, sites, special projects and entire neighbourhoods.

Our approach focuses on the three most important areas of energy infrastructure: heat and cooling, photovoltaics, and electromobility.

Together we will assess your areas for improvement to come up with measures that are energy efficient, sustainable and economical – and always in harmony with the lifecycle management of your real estate.

All data is collected, managed and evaluated comprehensively. For example, you can assign photovoltaic or electromobility services to individual occupants at no extra effort, and charge them transparently.

Climate protection and biodiversity are closely linked

Transformation to climate-neutral energy systems increases the value of your property portfolio. But it also benefits local flora and fauna.

Rapid climate change is affecting biodiversity, as many species are unable to adapt quickly enough to changing conditions. Conversely, the biodiversity crisis exacerbates climate change, as ecosystems play an important role in regulating the carbon balance.

Measures to achieve climate neutrality reduce the risks to biodiversity. Together with you, we are committed to promoting local biodiversity, which benefits the environment as well as quality of life.
