Environmental Protection in Connection with Conversions and New Construction

Challenges, Opportunities and Risks


  • Increasing requirements regarding the energy rating of individual buildings due to the German government’s climate target for 2050
  • Increasing requirements regarding materials vs. low acceptance for higher rents
  • Overall conditions for electromobility are not consistent with the goal of nationwide expansion – need for statutory changes and the expansion of grid capacities


  • Systematically demanding and implementing higher environmental requirements for production processes and building materials ingredients at supplier level due to economies of scale


  • Higher construction costs due to future pricing of carbon-intensive building materials, e.g., cement, or sustainability certificates
  • Higher construction costs due to more sustainable building methods pose a risk to the objective of providing housing for broad sections of the population
