Gründerzeit with future - subproject 5: Documentation and monitoring

The main aim is the documentation and monitoring of the demonstration projects within the scope of the project "Historical buildings of tomorrow" with regard to the technical implementation, investment and operation costs and to the energetic performance. All demonstration projects will be accompanied by an evaluation process regarding occupants' satisfaction and the refurbishment process. Beyond that, legal constraints for innovative refurbishment of historical buildings will be documented and proposals for adaptations of the rental law and refurbishment subsidy schemes will be developed.

Short Description

This project is a sub project of the flagship project "Gründerzeit with future: Innovative Modernisation of Wilhelminian style "Gründerzeit" Buildings"

Status

ongoing

Summary

Historical Buildings "Gründerzeitgebäude" (Wilhelminian style buildings, construction period approximately 1850–1918) are an essential part of the townscape of Vienna and many other cities. In Graz and Vienna up to one third of the flats are built in that period. Most of these objects show good structural conditions, but nevertheless, due to their characteristics (e.g. structured facades, box-type windows) and a high public interest in preserving the townscape specific renovation methods and technologies are highly needed.

In order to enforce the number and the quality of comprehensive renovations of historical buildings by applying innovative technological and organizational solutions the project "Historical buildings of tomorrow", supported by the RTD program "Building of Tomorrow plus" was established in 2009. Five demonstration projects show how innovative refurbishment of Wilhelminian style buildings can overcome technical, economical, social and legal barriers and achieve a great performance. This project is further divided into sub-projects, one of them being GdZ_SP5.

The main aim of this sub-project is the documentation and monitoring of the demonstration projects regarding their technical implementation, investment and operation costs and regarding the energetic performance. All demonstration projects will be accompanied by an evaluation process regarding occupants’ satisfaction (Post Occupancy Evaluation) and the refurbishment process. Beyond that, legal constraints for innovative refurbishment of historical buildings will be documented and proposals for adaptations of the rental law and refurbishment subsidy schemes will be developed.

The documentation of implemented technical measures will build upon a standardized structure. Monitoring of the energy performance and parameters of convenience will be applied securing comparable results beyond all demonstration projects.

Within SP5 also investment costs and costs for operation – for two years of operation – will be documented along a standardized cost structure scheme. In addition, economic efficiency calculations and life cycle cost analysis will be performed for the demonstration projects.

The project will also pay attention to changes of the structure of tenants before and after the refurbishment and it will evaluate the satisfaction of occupants with the result of the refurbishment process. Additionally, applicable solutions for occupied (or partly occupied) buildings will be developed and tenants will receive guidance to deal with new technologies (e.g. ventilation systems).

Finally, important constraints of the tenant law for an innovative modernization of "Gründerzeit" buildings will be documented for the demonstration project, and adaptations of the rental law and refurbishment subsidy schemes (with focus on Vienna) will be formulated.
