23 Digital Building Performance Test Bench Dr.-Ing. Stefan Plesser

24 Challenge: Quality and Data Buildings are complex technical systems Design, Construction and Operation are increasingly difficult. Risks for the technical and economic performance are growing. Innovative technical Components and Systems provide enormous amounts of data

25 synavision: Digital Building Performance Test Bench Digital Building Performance Test Bench uses this data for quality management in buildings. Is the first software for the specification and automated testing of building and system performance Works as a powerful web-based platform

26 How performance gets lost: Complexity in projects Energy Design: Conceptual Ideas 3D-Hardware-Planing: complexity explodes Textual(!) explanation of how it should work Building Management: What was the design idea? synavision GmbH Welle 15 D Bielefeld 26

27 The Challenge How do we do quality management for 10 buildings 100 buildings 1000 buildings? Increase productivity! synavision GmbH Welle 15 D Bielefeld 27
