Catalogue of Passivhouse Details for Refurbishments

A Catalogue of Passivhouse Details for Refurbishments for buildings of all building periods from the 1870 to the 1980s. Special consideration to the refurbishment of building parts in contact with the earth. Integration of controlled ventilation services. Construction elements description with drawings, building physical data and ecological life cycle assessment. This project aimed at contributing to "Replicable refurbishment concepts for meeting passive house (or comparable) standard in buildings of all building periods".

Short Description




Starting point/Motivation

Founding on the IBO Catalogue of Details for Passive Houses (funded by Building of the Future, Project No. 805 785) and a pilot study, that evaluated Building of the Future Renovation Projects (funded by Building of the Future, Project No. 813 968) IBO wishes to produce a catalogue of details for high quality building renovation.

Contents and Objectives

With a Catalogue of Details for Refurbishments up to the passive house standard level, which is proposed here, it is aimed to provide a standard reference for sustainable solutions and basics of renovation of old building stock. Construction details that are evaluated with regard to building physics, ecological life cycle and technical quality, will be offered to architects, contractors and building material producers. Typical refurbishment tasks as loft conversions, damp-proofing of cellars or renovation of façades will be dealt with systematically. Aspects of ecological life cycle evaluation and of hygiene (indoor air quality) will be considered in choosing among available innovative solutions.


Constructions will be shown as regular sections and connection details, supported by informative text.


Publication structured as follows

  • Basics
  • Renovation of building parts in contact with ground
  • Renovation of buildings of the Gründerzeit period (1870–1918) with or w/o classification as historical monument
  • Renovation of buildings from the periods 1920 to 1980 and renovation of earlier renovated buildings up to the passive house standard
  • Renovation of balconies and loggie
  • Renovation of single family detached houses in light-weight construction (from the 1960ies and later)
  • Integration of mechanical ventilation into existing buildings
  • Regular cross sections and functional units
