BMW (Bayerische Motoren Werke), as a company committed to sustainability, is interested in the environmental performance of its building. A life cycle assessment (LCA) study will help to provide the answers. An LCA enables an ecological classification and optimization of a product or a process compared with possible alternatives over the entire life cycle. However, the expenditure for performing a manual LCA study on complex products is very high. The approach involves the extension of the geometric model of BMW’s building to product models. Integrated software modules which are able to perform an LCA study have been developed from the research project F219 in TUM Lehrstuhl für Bauinformatik. The software modules are capable of performing an LCA study according to the ISO-Standard series 14040. Product models for a BMW building in Dingolfing, Germany were constructed within the framework of Autodesk Architectural Desktop 2005. An alternative was created to study the impacts. Life cycle inventory studies were carried out to complete the database. The product models constructed were analyzed using four different life cycle impact assessment methods.     «
