Residential Buildings



Strenger Holding GmbH, Ludwigsburg

Project duration

January 2021 – June 2021

The Strenger Group has set itself the goal of enhancing its market position in the field of sustainability. To this end, it wants to examine the environmental impact of its current building standard, with a particular focus on the carbon footprint of residential buildings throughout their entire lifecycle. This lifecycle analysis, which also includes a carbon audit, examines the different lifecycle phases – from production and construction to use and return of the building materials to the circular economy.

As part of the study, the Drees & Sommer experts also identified optimization potential for various standard modules.

“We are looking forward to an excellent long-term partnership with Drees & Sommer, as we believe in the value of carbon audits and in achieving sustainability in economical steps.”
