Systems Engineering in Building and City Design
Abstract Buildings cause a major part of world population's energy consumption and thus bear high responsibility for global warming. This calls for performance-oriented building design aiming at the development of design configurations with low resource consumption and emissions. The talk therefore presents a method for parametric systems modelling (PSM) in building design and urban planning supporting performance-oriented design by systems engineering. The approach uses the Systems Modelling Language (SysML), which is a common diagram language of systems engineering, and describes use cases, requirements, system structures, activities, item flows (energy and material) and parametric performance evaluations of artefacts of the building domain. The method extends existing parametric modelling methods in architecture, which are strongly geometry focused, in two respects: First, it leads to a multidisciplinary model overcoming geometric limitations. Second, it not only addresses the parametric variation of a static model structure but also includes the development process of the system structure by applying systems engineering in a requirement-driven and design-oriented way. This allows to explore the full potential of performance-oriented design. About the speaker Philipp Geyer is researcher and lecturer at the Chair of Information Technology in Civil Engineering of Bauhaus-Universität Weimar. His research area is sustainable building design supported by intelligent computer modeling and simulation. Currently, he conducts research on performance-oriented design by systems modeling as research fellow at Swiss Federal Institute of Technology Zurich. He holds a Dipl.-Ing. in architecture and a Dr.-Ing. (PhD) in building design and engineering from Berlin University of Technology. In his doctoral research, which he partly conducted as visiting scientist at Massachusetts Institute of Technology, he developed a method for applying Multidisciplinary Design Optimization in building design. This approach adapted methods from aerospace engineering and developed them further for supporting decision making in performance-oriented building design. Furthermore, he is responsible for system design, optimization and construction in the research enterprise Watergy. This enterprise develops innovative energy and water systems for sustainable buildings and greenhouses, which provide heating and cooling as well as water regeneration.
