Research output: Chapter in Book/Report/Conference proceedingsConference contribution


The focus of the research project “life cycle improvement of the building quality” (“Lebenszyklusorientierte Qualitätsoptimierung von Gebäuden – LQG”), financed by the FFG and six industry partners is to develop, analyze and evaluate methods to assess planning decisions with their consequences on the life time of a building. The calculation of investment costs often serves as the only basis for decision-making in the building planning. The existing set of approaches for assessment is used only in a limited number of decision processes. The purpose of a certain building is not cost efficiency or in environmental compatibility — its main purpose needs to be focused on usability. This inevitably is connected to the planned and accomplished quality. The project has two main outputs. One is the creation of a comprehensive guideline on sus-tainable building (=Database of Quality), the other is a common database on building life cycle data as well economical as ecological (=Database of Quantity). Both should be called “LQG-Tool”. The comprehensive guideline will be structured on the life cycle of a building and contain defined time slots, where decisions are necessary and what information will be helpful for a decision maker. The focus of the common database will lie on data, which have to be estimated during the planning of a building. These are LCC- and LCA- Data. As both of these Analyses need a calculation of the energy demand, the data are to be accomplished with the data from the energy performance certification. The comprehensive guideline and the data base will be placed in an internet portal, which shall give quick access to the scientific data. As this Internet portal is still in programming and the collection of scientific data is continuously but will also take some time to be useable, a prototype within excel called “enhanced energy certificate” (Energieausweis Plus) is created. The online comprehensive guideline will be presented.
