Gründerzeit with future: Innovative Modernisation of Wilhelminian style "Gründerzeit" Buildings

This project is a "Building of Tomorrow Plus"- flagship project

The aim of this project is to modernise these historical buildings in a systematic and holistic way using innovative technical and organisational solutions. This should lead to the substantial improvement of the thermal-energetic quality of future renovation projects and thus make a contribution to attaining a CO₂ neutral building sector.

Following activities will be initiated within this flagship project:

• Developingtransferable concepts as well as innovative technical and organisational solutions for renovating historical buildings
• Implementing the concepts and solutions within at least five innovative pilot projects (including documentation and monitoring)
• Dissemination of the results to owners and property managers, planers, architects, representatives of the building sector, including international networking

These pilot projects will be designed to show how technical, economic and social barriers that come up while restoring historical buildings in an innovative fashion can be overcome. The pilot projects will be located within the City of Vienna and cover a variety of historical buildings from historical workers’ quarters on the outskirts of town to the historical palais in the centre of town. The type of historical buildings that will be considered are residential buildings as well as buildings that encompass apartments as well as offices.

High visibility, practical relevance as well as an efficient dissemination of results will be secured by concentrating the pilot projectson the City of Vienna and working in close cooperation with several relevant municipal departments (e.g. those responsible for building subsidies – “wohnfonds wien”, building research – MA50, architecture – MA19). Specifically, the results of the flagship project will generate reliable knowledge for the further development of subsidies and the legal framework in this area. The results gathered in the City of Vienna as “a competence centre for historical buildings“ will be further disseminated on national level (Cities of Graz, Linz and Salzburg) as well as on international level within the framework of „city dialogs“ with Berlin, Munich, Prague, Budapest and Zurich.

Central innovations

The choice of pilot projects represents the full scope of historical buildings located in Vienna from historical workers’ quarters on the outskirts of town to the historical palais in the centre of town. The main innovations are to ensure the high quality of restoration by using passive house components (mechanical ventilation systems, high quality insulation, possibly also from the inside), newly developed windows as well as the systematic implementation of innovative climate neutral systems for HVAC.

The first pilot project in the 14thdistrict of Vienna was completed in December 2010. The follow-up activities of this project will be to monitor the energy use, the usability for clients as well as the accompanying evaluation.

The second pilot project „Davids Corner“ consisting of three historical buildings located next to each other will start in 2011.

Apart from this an own sub project is going to develop new window-façade-components with passive house standard, that also fulfil architectural criteria and those related to city planning. The components will be available for use within restoration projects starting 2011.

The sub project 4 is developing a portfolio management tool to implement and disseminate innovative concepts and solutions in property managing practice that are tailor-made to fit the specific framework conditions of historical buildings.
