A TESTBED FOR APPLYING OPERATIONALIZED GRAPH GRAMMARS TO SUSTAINABILITY ANALYSIS IN INTEGRATED BIM-GIS SCENARIOS

Abstract. Environmental aspects are becoming increasingly important for construction projects and thus holistic analysis spanning different scopes such as the building and city context. With graph-based data integration we propose a general method to support cross-domain analysis tasks. In this paper, we present a testbed consisting of a data set with three university buildings in IFC and CityGML format and two use cases for sustainability analysis spanning the building and city scope. We discuss the details of the data set and the two use cases - solar irradiation and material impact analysis - and show how graph-based data integration will be carried out in the testbed.
