Our Energy &
Environment Charter

The air source heat pump is a technology that we are increasingly relying on. Its strengths are particularly evident in combination with underfloor heating, increased external wall and roof insulation and windows with triple glazing. Here, the high energy efficiency ensures environmentally friendly operation with low CO2 emissions and moderate heating costs. Since the necessary energy is obtained from the outside air, it is also available free of charge and in unlimited quantities.

In the case of built-up areas, we provide compensation elsewhere and make our contribution to the balance: for example, extensive green roofs, especially in urban areas, promote biodiversity, bind particulate matter and serve as a buffer for rainwater.

When it comes to grey energy, we are steering towards a circular economy: the avoidance of waste already begins in the planning process and flows into the project planning across all development and construction phases. By selecting durable and, if possible, recyclable materials, we aim to reduce the burdens that we pass on to our children and grandchildren.
