PublicationEnvironmental aspects of lightweight construction in mobility and manufacturing( 2013)
;Baumann, M. ;Brandstetter, C.P. ;Krieg, H. ;Fischer, M.In automotive, mechanical, medical and plant engineering, and the construction industry, lightweight construction is considered one of the most important future technologies, providing good market opportunities for small and medium-sized companies. Due to the increasing relevance of energy and resource efficiency, not only technical and economic, but also environmental aspects have to be considered when assessing lightweight construction. Only with the consideration of environmental and economic aspects modern technologies can succeed in different fields of application and gain societies acceptance. In the study commissioned by the e-mobil BW GmbH in Germany, the topic of sustainability in lightweight construction is analyzed on basis of environment and health (Rommel et al. 2012). This article gives an overview on the most important findings and results of this study with special focus on the Life Cycle Assessment (LCA) of lightweight construction considering the light weight materials steel, high performance steel, aluminum and carbon fiber composites. -
PublicationSmart models as intelligent assistants in building LCA( 2010)
;Löwe, K. ;Fischer, M.Wittstock, B.Life Cycle Assessment (LCA) is one of today's key issues if we look at the environmental performance of building materials, construction components or especially if we discuss about the sustainability of entire buildings. LCA assists in answering questions concerning these topics by using specific software, such as the GaBi 4 software, and by setting up tailored models. The difficulties in designing such tailored models for building LCA are high expenditures of time for modeling, the need for flexibility in assessing conditions and the representation of various building circumstances. In the context of a sustainable certification according to the German Certification for Sustainable Construction (DGNB), a generic built and hierarchical drawn up model for an office building is assembled within the GaBi 4 software. Its structural design complies with the ISO 14040/44 standard, and with the requirements for a sustainable evaluation according to the German Certification for Sustainable Buildings and Construction. As fully parameterized model it was applied in practical certification process for assessing the environmental impacts of the accredited office building and furthermore its applicability was validated. Therefore, the structural assembly of the described model and the flexibility of application for other building types will be demonstrated and discussed, to work out, how a smart model for building LCA may look like. -

PublicationAnforderungen an den ökobilanziellen Vergleich verschiedener Bauweisen am Beispiel eines 1-2 Familienhaus( 2010)
;Loewe, K. ;Wittstock, B. ;Fischer, M.Im Kontext nachhaltiger ökologischer Wohngebäude ist die Datengrundlage bei neutralen Vergleichen unterschiedlicher Bauweisen derselben bisher sehr gering. Damit verbunden existieren derzeit nur wenige wissenschaftlich fundierte Erkenntnisse. Soll die Möglichkeit bestehen, eine ökologisch vorteilhafte Bauweise für den Wohnbau auswählen zu können, muss ein objektiver ökologischer Vergleich der gewählten Bauweise mit anderen alternativen Bauweisen durchgeführt werden. Die Grundlagen für einen solchen Vergleich und die Festlegung von Anforderungen an diesen, liefert das hier vorgestellte Vorgehen. Des Weiteren wird ein Gebäudemodell für die vergleichende Ökobilanzierung zur Verwendung in spezieller Ökobilanz-Software vorgestellt sowie dessen Anwendbarkeit anhand zweier Beispielgebäude praktisch aufgezeigt.
