Resource Conserving Renovation (Re_Co_Re) Energy efficient, resource conserving and differentiated renovation of historic European building stocks Synopse Development of integrated, long term and life cycle oriented approach to sustainable modernisation of historical building stocks Summary Starting point / motivation The goal of this research project is to objectify and deepen the knowledge base on the building stocks and further to develop applicable tools and strategic measures for their sustainable modernisation based on the notion of preserving of resources. Project partners will use common objectives and planning tools and will follow a common procedure in order to develop a specific national application which results from a historical, technical, social and cultural understanding of the specific national stock fragments. The particular building stock chosen for research in Austria will be the social housing of the modern era build between 1918 and 1934, the architecture of ¿Red Vienna¿; residential apartment blocks (Gemeindebau) and settlements (Siedlungen). Three characteristics: sufficient use of floor space within the housing unit, added common facilities and the principle of future additional space are essential for socio-cultural capital of these particular building types and are in themselves sustainable. Contents and goals The project will develop an integrated approach to sustainable renovation of historical building stocks and pre-1970th stocks which is based on common objectives, a common procedure, the common use of planning tools and a specific national application which results from a historical, technical, social and cultural understanding of the specific national stock fragments. Through cooperative analysis of the two types of housing (residential apartment blocks and settlements of the modern era), involving several disciplines (housing research, life cycle analysis, energy efficiency, structural analysis) these topics will be addressed: - the specifics of the particular building types and their potential - future use (innovative housing concepts, additional requirements, open buildings approach) - Evaluation of renovation models based upon sufficient use of space - Know how transfer: planning to operation and use - Renovation and participation Methods of treatment Based on preliminary research work of the academic partners and experience of the associated stakeholders, specific methods to deal with specific parts of the stock will be developed, compared and evaluated. Main research methods will be integrated life cycle analysis and the principle of differential refurbishment approach. In each country a particular part of the stock will be selected and buildings belonging to this stock will constitute the basis and template for the development of the methods. Expected results / conclusions - national criteria definition for long term renovation strategies (interdisciplinary and integral approach), - definition of long term integral renovation strategies, definition of time patterns for measures, - life cycle evaluation of long term strategies, based on evaluation of different scenarios, - development of integrated procurement models supporting life-cycle oriented planning and operation, - development of information/knowledge management systems for support of life-cycle oriented planning and operation - scenarios for know-how transfer from the planning into operation phase and use, - guidelines / Tool for development of long term scenarios based upon international results and comparison of outcome, - guidelines for investors, developers, real estate managers, planners and users for integrated renovation, management and use of refurbished building stocks
