Examples of Modernisation

diese Seite auf Deutsch

For frequently realised modernisation measures concerning shell elements of existing residential buildings, this collection of examples provides information on requirements, typical constructions and investment costs as well as guides for economic assessment.

The examples of modernisation are structured as follows:

  • Short description of the building component
  • Examples of the energy quality of existing building components
  • Description of the current energy performance requirements according to EnEV
  • Cost functions for estimating and differentiating construction costs
  • Calculation of examples using the BBSR calculation tool:
    Equivalent energy price, annuity and amortisation period displayed as matrix with estimated investment costs and estimated energy savings per square meter of refurbished component.

Further examples of modernisation – concerning technical building services – are currently under preparation.
